Biological Journal of the Linnean Society. It is likely hundreds more hygropetric species will be described in the coming decade, shifting the habitat from its once marginal status to one that is more mainstream. IX—2 Chapter IX—Order Coleoptera Unlike the Hemiptera, the larvae of Coleoptera are morphologically and behaviourally different from the adults, and their diversity is high. Hydrochus falsus Hellman in Worthington et al., 2016). The full text of this article hosted at iucr.org is unavailable due to technical difficulties. How the families are positioned within Elateriformia, and even if they are themselves reciprocally monophyletic, remains unclear. 0000001429 00000 n Previous classifications of gyrinids were based principally on morphological works by Beutel (1989a,b, 1990) and Beutel & Roughley (1994). 0000016688 00000 n Some early descriptions have been shown to be misattributed to the lineage or lack characters that would allow unambiguous attribution, underscoring the need for critical review of historical records. The aquatic larvae of the Diptera are often the most abundant and most diverse group of the benthic macroinvertebrate fauna. Hydrophilidae, also known colloquially as water scavenger beetles, is a family of chiefly aquatic beetles. Burmese amber reveals a new stem lineage of whirligig beetle (Coleoptera: Gyrinidae) based on the larval stage. Watch videos of the live benthics to see how they move and view pictures of their different life stages. %PDF-1.4 %���� Having accurate accounting of the diversity within water beetle lineages is critical to facilitating and accelerating both taxonomic and evolutionary research within the group. Most water beetle families have modern catalogues which are updated on a regular basis. Learn more. The phylogeny and classification of Noteridae was revised by Miller (2009) based on a cladistic analysis of morphological data. Indeed, water beetles were early test‐subjects of such methods (Miller et al., 2005), and remain a focal group for exploring the opportunities and limitations of DNA barcoding (e.g. The pupal phase of all coleopteransis technically terrestrial, making this life stage of beetles the onlyone that has not successfully invaded the aquatic habitat. stygobionts; Miller et al., 2009) or ‘known unknowns’ from previously unpublished theses (e.g. In general the larvae of aquatic beetles may be said to be modified in respect of respiratory apparatus but otherwise they greatly re semble terrestrial larvae. I have omitted a few groups that some workers might generally consider aquatic, in particular the Limnichidae and Scirtidae. Fossils of the family Haliplidae have been rare but are known as far back as the lower Cretaceous (Prokin & Ponomarenko 2013, Prokop et al.

Distribution of aquatic beetles from the east of Morocco (Coleoptera, Polyphaga) We present old and new faunistic and distributional data on aquatic Polyphaga (Coleoptera) from the east of Morocco, comprising the Oriental Region and the basin of Moulouya River. benthic macroinvertebrate by exploring the life cycle, feeding habitats, interesting facts and its role in the food chain. 0000002582 00000 n Grant No. Michat et al. The majority of extant aquatic beetle families are now known in the fossil record. A few species) additional families have a limited number of aquatic species. Consequently, sequencing both the target immatures alongside a battery of potential adults remains necessary in most cases. Consequently, although there is no question that thousands of new species of aquatic beetles remain to be discovered or described, they are among the better‐known and best‐catalogued groups of beetles. Stephen Baca, David Bilton, Jennifer Girón, Grey Gustafson, Martin Fikáček and Ignacio Ribera graciously provided valuable feedback on early drafts of this manuscript. In addition to providing important insights on character evolution, the robust fossil record provides critical information for time‐calibration of phylogenies and consequently supports aquatic beetles as a model system in evolutionary biology. ^��ړW˵gV�\S۳x�=,]j�kyݐ��\/��sA#������‚�3��w,�+Q���^i��|�E�����׮�H}����vdx�E����E��#��O#�ؑKj��c f�6`.�lР�b��N�E���O�SmV>�a7&n`SM��&�C�}Ua�5~�' Using taxonomic revision data and controlling for several variables such as body size and geography, Nilsson‐Örtman & Nilsson (2010) used modelling methods to estimate the actual number of species of diving beetles to be 5405, which would mean that Dytiscidae is presently ∼80% described (Nilsson, 2016). The Coleoptera (beetles) is the most speciose of all the insect orders with over 5,000 aquatic species. Of the four currently recognized subfamilies of Hydraenidae, most larval descriptions are from the more species‐rich and widespread Hydraeninae and Ochthebiinae. Larvae The relationships between, and within, the families of aquatic Byrrhoidea are the least understood among water beetle lineages. A potentially older elmid from Cretaceous Spanish Amber was removed from the family (Bukejs et al., 2015; see also for a review of Baltic Amber Elmidae). They have a variety of morphological adaptations for aquatic life. The larvae of Orchymontiinae was described for the first time by Delgado & Palma (2004), but immature stages remain unknown for the Afrotropical endemic Prosthetopinae. Ribera et al., 2008; Bloom et al., 2014). I am grateful to Pete Cranston whose suggestion sowed the seed for this review as well as his subsequent critiques. 0000001238 00000 n C). Both larvae and adults are predators, mainly on other arthro- About 1% of the known species of Coleoptera have an aquatic pods. Three new genera of acidocerine water scavenger beetles from tropical South America (Coleoptera, Hydrophilidae, Acidocerinae).

Coleoptera. Many aquatic habitats are definable and discrete in space and time, a luxury more difficult to find in terrestrial systems. Here, I attempt to summarize the current state‐of‐the‐art of water beetle systematics, including a synthesis of recent literature on how well water beetle taxa are described, the degree to which we understand their evolutionary relationships, and in what ways they are being used as model systems in systematics. All citations, no matter how old, that are not contained in the complete on-line bibliography may be included each year. Going underwater: multiple origins and functional morphology of piercing-sucking feeding and tracheal system adaptations in water scavenger beetle larvae (Coleoptera: Hydrophiloidea). In this study the diversity and habitat selection of aquatic Coleoptera has been assessed. Using a combination of adult and immature characters and a single gene, Miller (2001a, 2003) made the first attempt to infer a family‐wide phylogeny. 0000003108 00000 n Can DNA barcodes of stream macroinvertebrates improve descriptions of community structure and water quality? D) with the spiracles on the terminal abdominal segment forming sclerotized hooks (Fig. I also provide a ‘horizon scan’ of where water beetle systematics is going, and how its prominence and role in shaping our understanding of evolutionary biology will continue to increase. For simplicity and the purposes of this review, I limit discussion to families within the five major groups in which the vast majority of species have adults and/or larvae occupying aquatic habitats: Myxophaga, ‘Hydradephaga’, Hydraenidae, Hydrophiloidea and the core aquatic Byrrhoidea (Dryopidae, Psephenidae, Lutrochidae, Elmidae). Larvae undergo from 3 to 8 molts. 0000000016 00000 n Although new species are still to be found, they are often either isolated/unusual endemics (e.g. wuhana and Luciola cruciata were bred in tap water following the method outlined in Fu et. lateralis, Aq. 2004).

(2017) provide a comprehensive review and discussion of dytiscid larvae in a phylogenetic framework, as well as paper and online keys to the larvae of the subfamilies and tribes of the diving beetles of the world. Many ambitious surveys that focussed in total or in part on water beetles have been carried out in the last quarter of a century, including those in China (Jäch & Ji, 2003), Venezuela, Madagascar, Costa Rica, New Caledonia (Jäch & Balke, 2010), United Arab Emirates (e.g. The Afrotropics and particularly the Oriental region are likely to have many new species awaiting discovery. E). Došlo je do pogreške. In their analyses, neither Psephenidae nor the subfamilies of Elmidae (Elminae and Larainae) were monophyletic. (2000) is also a good source of larval keys and illustrations, albeit focused on North America. This video is unavailable. The families Noteridae, Amphizoidae and Meruidae lack described fossils; none are attributed to the Aspidytidae, although the extinct family Liadytidae is extremely similar and may prove to be confamilial. Notes on Stenhelmoides and description of the true male genitalia of S. strictifrons Grouvelle, 1908 (Coleoptera: Elmidae). For breathing, some diving beetles (Coleoptera) and bugs (Hemiptera) entrap an air bubble beneath the … In the most robust study to date, Kundrata et al. Of the five smaller families, only the internal relationships of Helophoridae have been examined (Fikáček et al., 2012a,b). This rich diversity is not the result of a single aquatic invasion, but rather of repeated macroecological shifts from terrestrial habitats throughout more than 300 Ma of evolutionary history (Toussaint et al., 2017b). 0000002881 00000 n Psephenidae, Scirtidae). (2015) place the Hydrophiloidea as well as Hydraenidae in the context of staphyliniform evolution, being sister to Histeroidea and within Staphylinoidea respectively. Similarly, larvae have been described for representatives of all families, subfamilies and tribes of Hydrophiloidea, and despite continued progress, our knowledge at the genus and species level remains substantially underdeveloped (Archangelsky et al., 2016). In fact, spiracles, except for the posteriormost in some, are normally greatly reduced on aquatic beetle larvae. Coleoptera families (INBIO, Costa Rica). Mouth morphology of the diving beetle Hyphydrus japonicus (Dytiscidae: Hydroporinae) is specialized for predation on seed shrimps. Legs with 5 segments (not counting tarsal claw) (Fig. 12.8); abdomen terminating with 1-2 long filaments.....Haliplidae 3'. No molecular data has been applied to the evolution of Haliplidae, and the phylogenetic validity of some smaller genera is uncertain; phylogenies based on morphological data have been inferred for the family (Beutel & Ruhnau, 1990) as well as the genus Brychius (Mousseau & Roughley, 2007). endstream endobj 27 0 obj<> endobj 28 0 obj<> endobj 29 0 obj<>/ColorSpace<>/Font<>/ProcSet[/PDF/Text/ImageC/ImageI]/ExtGState<>>> endobj 30 0 obj<> endobj 31 0 obj<> endobj 32 0 obj<> endobj 33 0 obj[/ICCBased 42 0 R] endobj 34 0 obj[/Indexed 33 0 R 255 46 0 R] endobj 35 0 obj<> endobj 36 0 obj<> endobj 37 0 obj<>stream (2017b) provided more detailed reviews on hypotheses of relationships among adephagan families. 2001 Aquatic Coleoptera Bibliography compiled by Sharon Jasper.

(2013) and Gomez & Damgaard (2014) for recent summaries of fossil Hydradephaga. Although most aquatic byrrhoid families are known in the fossil record, the oldest known representatives (to date) are comparatively young, with Elmidae and Psephenidae known from the Eocene, and Dryopidae and Lutrochidae from the Oligocene (Ponomarenko & Prokin, 2015). The status of fossil Psephenidae are reviewed in Wedmann et al. 1516149 | Learning to See, Seeing to Learn A Sociotechnical System Supporting Taxonomic Identification Activities in Volunteer-Based Water Quality Biomonitoring Fontidessus Miller & Spangler 2008, Spanglerodessus Miller & García 2011, Petrodessus Miller, 2012), Hydrophilidae (e.g. Coleoptera are holometabolus, thus possess distinct egg, larval, pupal, and adult stages. Aquatic larvae are associated with organic matter (leaf packs and rotting wood) or rocks in streams. The larval phylogeny largely agrees with Miller & Bergsten (2014) with regard to the monophyly of most tribes and subfamilies, though there are exceptions (e.g. New seepage genera have been described in Dytiscidae (e.g. This changed dramatically with the discovery of a vast community of diving beetles living in calcrete aquifers in Western Australia (e.g. and you may need to create a new Wiley Online Library account. The families treated in this review have an approximate total diversity of ∼13 000 described species. (2017) provide an independent estimate of dytiscid phylogeny based solely on larval characters. The megadiverse genus Hydraena, with nearly 1000 described species, has been the subject of several recent molecular phylogenies to sort out this explosive diversity (Trizzino et al., 2011, 2013). The larvae of most myxophagan genera are described (10 of 13). Phylogenies examining interfamilial relationships using adult (Beutel, 1999) and larval characters (Beutel et al., 1999, but excluding Lepiceridae) have found a generally consistent branching pattern of (Lepiceridae + (Torridincollidae + (Hydroscaphidae + Sphaeriusiidae))). Hydradephaga, including some now‐extinct families (e.g. Tobochares Short & García 2007, Radicitus Short & García 2014) and Hydroscaphidae (Confossa, Short et al., 2015). (2016). 146 | 3(1').

Water beetles have been a popular study group among professional and amateur entomologists alike, even boasting their own international society, the UK‐based Balfour‐Browne Club. Much of the higher‐level relationships of Hydraenidae remain untested and given that both groups have substantial ecological variability, major classification changes are likely. Larvae are known to live in semiaquatic or aquatic habitats, such as decaying damp logs and organic muck. Insect Systematics and Evolution 36: 371–394. Coleoptera of Rhode Island: An on-line database. Many additional terrestrial beetle families have taxa with significant aquatic modifications (e.g. Insects generally dominate freshwaters in terms of species number, biomass and productivity.

Coptoclavidae) allied to Gyrinidae and Hygrobiidae, have a fossil record of both larval and adult forms extending back to at least the Early Triassic (Beutel et al., 2013; Ponomarenko & Prokin, 2015). These discoveries have only driven additional fieldwork in these habitats which in turn have illuminated yet more previously unrecognized hygropetric communities. Our knowledge of the diversity and phylogeny each of the 23 families water beetles is reviewed. ENVIRONMENT. (2006b, c). Description: Larvae are elongated, with flattened lateral projections, and 2 short spine like cerci (tails).Adults have a broad appearance and are reddish brown to black.L ength 10-15mm.. Habitat: In cold mountain streams. From a geographical standpoint, whereas many areas warrant and deserve inventory work, tropical South America and the zone of tropical Asia including and bounded by southern China–India–Malaysia likely will yield the highest percentage and volume of new taxa and lineages.

Assuming that this represents in aggregate between 65 and 75% of the actual diversity, there are roughly between 17 000 and 20 000 water beetle species. Two particularly remarkable recent findings relating to the ecology of aquatic beetles have been the subterranean radiation of diving beetles in Australia, and the unveiling of a poorly understood and little‐known guild of hygropetric water beetles. With the exception of a recent comprehensive molecular phylogeny of Hydroscaphidae (Short et al., 2015), no phylogenies have been published that substantively examine relationships within any family of Myxophaga. The Palaearctic already is relatively high in species richness but much better described than the tropical regions. (2016) elevated Protelmini (a small group of about six described species from the Afrotropics and Neotropics) from a tribe of Elmidae to its own family, Protelmidae. By far the largest family, Dytiscidae has been subject to more phylogenetic studies than any other water beetle group (Table 2). Consequently, water beetles do not form a single clade but are better described as an ecological guild distributed across at least 30 families in three of the four coleopteran suborders. Kirejtshuk, 2009). At higher taxonomic levels, our knowledge of aquatic beetle larvae is fairly robust, with the larvae even of the newest families Aspidytidae and Meruidae having been described (Alarie & Bilton, 2005; Alarie et al., 2011b). Diving beetle fossils attributable to extant clades have been described from Baltic and Dominican amber, including representatives of Copelatinae (Copelatus aphroditae Balke, 2003; Copelatus predaveterus Miller, 2003; Miller & Blake, 2003), Hydroporinae (Hydroporus carstengroehni Balke et al., 2010), and Agabinae (Hydrotrupes prometheus Gomez & Damgaard, 2014). Because there are not yet any reviewable data for the justification of this new family, I have treated it as part of Elmidae for the purpose of this review (similarly, a figure of an elmid phylogeny depicted in Kodada et al. Overviews can be found in Lawrence & Reichardt (1991) and Beutel & Vanin (2016). The fossil record of Hydrophiloidea has been extensively expanded in recent years (Fikáček et al., 2010, 2012a, 2014, 2017; Fikáček & Engel, 2011) and now extends back 150 Ma to the Jurassic. startxref 1, Table 1), water beetles are one of the most globally abundant groups of aquatic insects. Due to being defined by ecology rather than a single clade, which groups fall under the aquatic beetle umbrella differ slightly depending on the specialist. Although regional treatments and generic revisions exist to a certain extent for some groups, the recent publication of Miller & Bergsten's (2016) comprehensive resource on diving beetle biology and identification put into sharp relief the varying degrees to which water beetle identification is feasible. That changed with the discovery of two previously unrecognised beetle families from seeps, namely Aspidytidae from South Africa and China (Ribera et al., 2002a; Balke et al., 2005), and Meruidae from Venezuela (Spangler & Steiner, 2005). These types are found in many species of beetles (Coleoptera) and some lacewings (Neuroptera) The decision at this point is more subjective. Other aquatic larvae, such as Aquatica ficta, Aq. However, almost all aquatic and semiaquatic Coleoptera pupate terrestrially with the exception of a few taxa (e.g. Perkins 2005, 2006; Short, 2010; Short & Garcia, 2010; Clarkson & Short, 2012; Bilton, 2016). More than 300 new species have been described from the Neotropics in the last 10 years alone. Learn about our remote access options. In one recent attempt to estimate the actual diversity, Jäch & Balke (2008) suggested that water beetles were approximately 70% described (although their circumscription of water beetles differs slightly from that of this review). � �0���Ḧ��'3����Fn"�_�ֱ The Nearctic, accounting for just ∼8% of water beetle diversity (Jäch & Balke, 2008), is both the best known and also the most species‐poor region. Cretodineutus rotundus gen. et sp. Phylogenomic analysis of the beetle suborder Adephaga with comparison of tailored and generalized ultraconserved element probe performance. The branching pattern of the hydradephagan families has received significant attention, although no strong consensus on interfamilial relationships has yet emerged. Lawrence et al. However, these databases often focus on what are already the most well‐known and well‐studied regions, and any widespread use of the method in the more diverse tropical regions remains purely theoretical. However, many of these other early larger‐scale studies were confounded by incomplete sampling of major lineages or poor resolution/low support along the backbone of the tree. Many are familiar to us like ladybugs, Japanese beetles, fireflies and dung beetles. 0000002452 00000 n 0000009381 00000 n About 25,000 species occur in North America, north of Mexico, but only about 1200 of these are purely aquatic. 0000006179 00000 n Aquatic beetles are consumed in both immature and adult stages. piercing the air cells of aquatic plants. Laccophinae being a highly nested, late diverging lineage in Miller & Bergson but sister to the remaining Dytiscidae in Michat et al., 2017). Kirejtshuk, 2009; Cai et al., 2012), including magnificently preserved specimens of Lepiceridae from Burmese amber (Kirejtshuk & Poinar, 2006; Ge et al., 2010; Jaloszynski et al., 2017) – a family now restricted to the northern Neotropics. Subterranean aquatic habitats such as underground cave and aquifer systems have long been known to host unique water beetle communities. The reasons for the relative popularity of aquatic beetles include: (i) their sheer abundance and broad distribution – they are easy to collect almost anywhere; (ii) their occasionally large size, with some adult species exceeding 5 cm in length, makes some species highly visible and some of these are even kept as pets; (iii) their diversity and often beautiful colour patterns, particularly evident in some diving beetles; and (iv) the breadth of their ecologies and behaviours – from incompressible plastrons in Elmidae to repeated aquatic/terrestrial habitat shifts in Hydrophilidae – ensure water beetles are tractable for a range of biological questions.
