TL;DR: The morphological, molecular and combined phylogenies mostly agree with the current classification of the group, but in some cases the results are in contradiction with established genera.
Abstract: The subtribe Deronectina Galewski, 1994 (Dytiscidae, Hydroporinae, Hydroporini) is distributed in the Nearctic, in the north of the Neotropical region, and in the Palaearctic and Afrotropical regions. It is currently composed of 194 species and 13 subspecies in eight genera: Amurodytes Fery & Petrov, 2013, Boreonectes Angus, 2010, Deronectes Sharp, 1882, Nebrioporus Regimbart, 1906, Oreodytes Seidlitz, 1887, Scarodytes Gozis, 1914, Stictotarsus Zimmermann, 1919, and Trichonectes Guignot, 1941. We present a morphological and a molecular phylogeny of the species of the subtribe, and a revision of their taxonomy to accommodate our phylogenetic results. The morphological phylogeny is based on the study of 54 characters of the adults of 189 species and 2 subspecies, of which 114 species and the 2 subspecies were coded in the morphological matrix. For the molecular phylogeny we investigated 115 species and 11 subspecies, using a combination of fragments of four mitochondrial (COI, 16S rRNA, tRNA-Leu and NAD1) and two nuclear genes (18S rRNA and H3), analysed with maximum likelihood and Bayesian methods. For both datasets we included the type species of all genus-group taxa. The morphological, molecular and combined phylogenies mostly agree with the current classification of the group, but in some cases our results are in contradiction with established genera. Most remarkable are the polyphyly of Stictotarsus and Nebrioporus , the low support for the monophyly and internal phylogeny of Oreodytes , and the low support for the monophyly of Deronectina with molecular data. Thus, we introduce some taxonomic changes in the current classification to accommodate the generic concepts to our phylogenetic results. Nine new genera are established: Clarkhydrus n. gen. (type species Hydroporus roffii Clark, 1862), Hornectes n. gen. (type species Hydroporus quadrimaculatus Horn, 1883), Iberonectes n. gen. (type species Deronectes bertrandi Legros, 1956), Larsonectes n. gen. (type species Potamonectes minipi Larson, 1991), Leconectes n. gen. (type species Hydroporus striatellus LeConte, 1852), Mystonectes n. gen. (type species Deronectes neomexicanus Zimmerman & Smith, 1975), Nectoboreus n. gen. (type species Hydroporus aequinoctialis Clark, 1862), Nectomimus n. gen. (type species Oreodytes okulovi Lafer, 1988), and Zaitzevhydrus n. gen. (type species Hydroporus formaster Zaitzev, 1908). Three genera are reinstated as valid: Deuteronectes Guignot, 1945 (stat. rest.) (type species Hydroporus picturatus Horn, 1883), Nectoporus Guignot, 1950 (stat. rest.) (type species Hydroporus abbreviatus Fall, 1923), and Neonectes J. Balfour-Browne, 1940 (stat. rest.) (type species Hydroporus natrix Sharp, 1884). Thirty-six new combinations for species and subspecies thus far treated in the genera Boreonectes , Nebrioporus , Oreodytes and Stictotarsus result from the new classification: Clarkhydrus corvinus (Sharp, 1887) n. comb., C. decemsignatus (Clark, 1862) n. comb., C. deceptus (Fall, 1932) n. comb., C. eximius (Motschulsky, 1859) n. comb., C. falli (Nilsson, 2001) n. comb., C. interjectus (Sharp, 1882) n. comb., C. minax (Zimmerman, 1982) n. comb., C. opaculus (Sharp, 1882) n. comb., C. roffii (Clark, 1862) n. comb., C. spectabilis (Zimmerman, 1982) n. comb., Deuteronectes angustior (Hatch, 1928) n. comb., Hornectes quadrimaculatus (Horn, 1883) n. comb., Iberonectes bertrandi (Legros, 1956) n. comb., Larsonectes minipi (Larson, 1991) n. comb., Leconectes striatellus (LeConte, 1852) n. comb., Mystonectes coelamboides (Fall, 1923) n. comb., M. grammicus (Sharp, 1887) n. comb., M. neomexicanus (Zimmerman & Smith, 1975) n. comb., M. panaminti (Fall, 1923) n. comb., M. titulus (Leech, 1945) n. comb., Nectoboreus aequinoctialis (Clark, 1862) n. comb., N. dolerosus (Leech, 1945) n. comb., N. funereus (Crotch, 1873) n. comb., Nectomimus okulovi (Lafer, 1988) n. comb., Nectoporus angelinii (Fery, 2015) n. comb., N. congruus (LeConte, 1878) n. comb., N. crassulus (Fall, 1923) n. comb., N. obesus obesus (LeConte, 1866) n. comb., N. obesus cordillerensis (Larson, 1990) n. comb., N. rhyacophilus (Zimmerman, 1985) n. comb., N. sanmarkii sanmarkii (C.R. Sahlberg, 1826) n. comb., N. sanmarkii alienus (Sharp, 1873) n. comb., N. sierrae (Zimmerman, 1985) n. comb., N. subrotundus (Fall, 1923) n. comb., Zaitzevhydrus formaster formaster (Zaitzev, 1908) n. comb., and Z. formaster ulanulana (C.-K. Yang, 1996) n. comb.

TL;DR: A large number of oviposition sites have been identified as high-risk predation sites in both the Northern and Southern Black-winged Pratincole species, suggesting that females that are able to correctly assess the risk of predation and use that information to avoid high- Risk Oviposition Sites should be favoured.
Abstract: 1. Theory predicts that natural selection should favour females that are able to correctly assess the risk of predation and then use that information to avoid high-risk oviposition sites to reduce ...

TL;DR: The first terrestrial terrestrial Hydroporus known to science is described in detail and important features are illustrated in this paper, where a single male accidentally found when collecting Staphylinidae (Coleoptera) in south-western Georgia (Caucasus) by sifting more or less dry material quite far from any water.
Abstract: Hydroporus novacula sp. n. is described on a single male accidentally found when collecting Staphylinidae (Coleoptera) in south-western Georgia (Caucasus) by sifting more or less dry material quite far from any water. The species belongs to the longulus-group of the genus (former subgenus Sternoporus). However, the shape of the median lobe, the club-like pro- and mesotibiae and the evenly curved protarsal claws separate it from all other species of the group. Additionally, no natatory setae could be detected on any leg of the single male studied. Together with the collecting circumstances, it appears not unlikely that the new species is the first terrestrial Hydroporus known to science. The species is described in detail and important features are illustrated.

TL;DR: A third set of corrections and additions is given to the World Catalogue of Dytiscidae including the first and second sets of Corrections and additions (NILSSON 2003 & 2004).
Abstract: A third set of corrections and additions is given to the World Catalogue of Dytiscidae (NILSSON 2001) including the first and second sets of corrections and additions (NILSSON 2003 & 2004). Megadytes lherminieri (GUERIN-MENEVILLE, 1829) has priority over M. giganteus (LAPORTE, 1835). The species name Dytiscus silphoides P ONZA, 1805 is declared as a nomen oblitum, in order to ensure the continuous usage of its junior synonym Deronectes opatrinus (GERMAR, 1824) as a valid name (nomen protectum). The preoccupied name Hydroporus ruficeps A UBE, 1838 is replaced with Hydroporus pseudoniger nom.n. New taxa published before January 1, 2006 are added. The number of recent species of the family Dytiscidae is now 3959.

TL;DR: Groups of functionally-related species within the orders Odonata, Trichoptera and Coleoptera each exhibited possible temporal and/or spatial segregation.
Abstract: The life histories, densities and distribution patterns of the most abundant macroinvertebrates, exclusive of chironomids and oligochaetes, are reported for a low-gradient, second-order, blackwater stream on the Coastal Plain of South Carolina, USA. Univoltine life histories were found for all species of Coleoptera (Ancyronyx variegata, Macronychus glabratus, Dubiraphia quadrinotata and Hydroporus clypealis) and most species of Ephemeroptera (Eurylophella temporalis, Paraleptophlebia volitans and Hexagenia munda), although the mayfly Stenonema modestum was at least bivoltine. Both univoltinism (Macrostemum carolina and Pycnopsyche luculenta), partial bivoltinism (Nyctiophylax affinis) and complete bivoltinism (Hydropsyche decalda, Cheumatopsyche sp., Phylocentropus placidus and probably Chimarra florida) were found among the Trichoptera. Odonate species were both univoltine (Calopteryx dimidiata, Enallagma divagans and Epitheca cynosura) and semivoltine (Boyeria vinosa, Gomphus lividus and Macromia georgina). The alderfly Sialis aequalis and the isopod Asellus laticaudatus were univoltine, while the blackfly Simulium taxodium produced at least 6 generations per year. Groups of functionally-related species within the orders Odonata, Trichoptera and Coleoptera each exhibited possible temporal and/or spatial segregation.
