We investigated phylogenetic relationships among pond skaters (Heteroptera: Gerridae) of the genus Limnogonus Stål 1868 by performing separate and combined parsimony analyses of DNA sequences from three mitochondrial (COI + II, 16SrRNA) and one nuclear (28SrRNA) gene(s). The taxon sample represented almost two thirds of the known diversity, and with most taxa represented by two or more individuals. A simultaneous analysis of all data showed that L. luctuosus Montrousier 1865 was paraphyletic and suggests that " L. luctuosus" from Australia and possibly also a population from the Society Islands (Moorea) each represents unrecognized species. L. fossarum F. 1775 was strongly supported, but the two subspecies L. f. fossarum F. 1775 and L. f. gilguy Andersen and Weir 1997 were paraphyletic. The two currently recognized subgenera Limnogonus (s. str.) Stål 1868 and L. (Limnogonoides) Andersen 1975 were paraphyletic, and were accordingly broken up in several monophyletic groups, each containing one or more species. From Limnogonus (s. str.) we delimited five clades: I (comprising L. aduncus Drake & Harris 1933, L. recens Drake and Harris 1934, L. profugus Drake & Harris 1930 and L. ignotus Drake and Harris 1934, all from the Neotropical Region), II (comprising L. nitidus Mayr 1865 from the Oriental Region), III (comprising L. franciscanus (Stål 1859) from the New World and L. cereiventris (Signoret 1862) from the Afrotropical Region), IV (comprising L. hungerfordi Andersen 1975 and L. luctuosus Montrousier 1865 from the Oriental and Australasian Regions) and V (comprising L. fossarum F. 1775 from the Oriental and Australasian Regions). From L. (Limnogonoides) we delimited two clades: VI (comprising L. intermedius Poisson 1941 from the Afrotropical Region and L. pectoralis (Mayr 1865) from the Oriental Region) and VII (comprising L. hypoleucus (Gerstaecker 1873), L. nigrescens Poisson 1941, L. poissoni Andersen 1975, and L. capensis China 1925 from the Afrotropical Region). Finally, L. (s. str.) windi Hungerford & Matsuda 1961 from Australia was placed as sister to clades I-VI. A manual optimization of geographical distribution onto the strict consensus tree suggests that Limnogonus is primarily an Old World group with independent transitions to the New World in L. franciscanus and in the common ancestor of Clade I. © 2010 Elsevier Inc.

Seven new species of the genus Hesperus Fauvel 1874 from China are described and illustrated: H. beijingensis sp. n. from Beijing, Henan, Hubei, Anhui, Zhejiang, Fujian, Sichuan and Yunnan; H. hainanensis sp. n. from Hainan and Guangxi; H. emeishanus sp. n. and H. pulchellus sp. n. from Sichuan; H. coarcticollis sp. n. from Yunnan; H. gracilantennatus sp. n. from Tibet and H. elongatussp. n. from Yunnan and Hainan. Hesperus amabilis (Kraatz 1859) from Sichuan and Yunnan, and H. susannekontrusae Schillhammer 2005 from Hainan are reported from China for the first time. In addition, H. amabilis is also reported from Afghanistan, Thailand and Laos for the first time. Hesperus feae Fauvel 1895 Is placed in synonym with H. amabilis (Kraatz 1859). Thus, a total of 12 species of the genus Hesperus are known from China; and the world fauna of the genus is now increased to 219 species. A key to the Chinese species of the genus Hesperus is provided and species geographical distributions are discussed.

The Chinese species of the genus Thoracostrongylus Bernhauer, 1915 are reviewed. Five new species are described: Thoracostrongylus acerosus sp. nov. from Sichuan and Hubei, Th. aduncatus sp. nov. from Yunnan, Th. baoxingensis sp. nov. from Sichuan, Th. diaoluoensis sp. nov. from Hainan and Th. fujianensis sp. nov. from Fujian. Thoracostrongylus birmanus (Fauvel, 1895) is recorded from China for the first time. Male genitalia and other critical characters are illustrated not only for the new species but also for the remaining Chinese species, namely Th. Formosanus Shibata, 1982, Th. malaisei Scheerpeltz, 1965, Th. miyakei Bernhauer, 1943 and Th. velutinus Scheerpeltz, 1965. © 2011 Taylor & Francis.

The phylogenetic relationships among selected species and genera of Mesoveliidae (Insecta: Hemiptera: Heteroptera: Gerromorpha) were investigated in a parsimony analysis of 2858 bp of DNA sequence data from the genes encoding COI+II, 16S rRNA and 28S rRNA. The resulting phylogeny showed that Mesoveloidea williamsiHungerford, 1929, from the subfamily Madeoveliinae, was sister group to Mniovelia Andersen & J.T. Polhemus, 1980, from the Mesoveliinae, thus making the latter subfamily paraphyletic. The genus MesoveliaMulsant & Rey, 1852 also showed to be paraphyletic, since an undescribed Laotian relative of M. indicaHorváth, 1915 and M. ujhelyiiLundblad, 1933 resulted as sister group to PhrynoveliaHorváth, 1915; and M. amoenaUhler, 1894 was sister species to Speovelia maritimaEsaki, 1929. Whereas these relationships were poorly or moderately supported, the remaining species of Mesovelia formed two distinct and well-supported clades, one comprising M. horvathiLundblad, 1933, M. hackeriHarris & Drake, 1941, and two undescribed species from Nigeria and New Caledonia, and another comprising M. vittigeraHorváth, 1895, M. stysi J.T. Polhemus & D.A. Polhemus, 2000, M. ebbenielseniAndersen & Weir, 2004, M. furcata Mulsant & Rey, 1952, and M. mulsantiWhite, 1879. A large genetic difference was found between populations of M. vittigera from Europe and Africa on one side and populations from Australia and New Caledonia on the other. DNA sequence data from a Japanese "M. vittigera" obtained from GenBank placed the specimen as strongly supported sister group to a Danish specimen of M. furcata. Comparisons of the 28S rRNA sequence data between the two specimens revealed a single C/T transition, while comparison with a Chinese female of M. furcata revealed one A/G and one C/T transition, thus suggesting mislabelling of the Japanese specimen, or an unrecognized presence of M. furcata in Japan. Considerable genetic differentiation was found between specimens of M. horvathi from Australia, New Caledonia, New Guinea, and Laos, and between sympatric specimens of M. mulsanti from Honduras, thus supporting earlier ideas of species-complexes in these two clades. Samples of Austrovelia caledonicaMalipatil & Monteith, 1983 from New Caledonia and Mniovelia kuscheli Andersen & J.T. Polhemus, 1980 from New Zealand’ s North Island also revealed considerable intraspecific divergences indicating genetic isolation among geographically separated populations on these ancient islands. © 2012 by Koninklijke Brill N.V., Leiden, The Netherlands.

Vombisidris jacobsoni (Forel, 1915) is redescribed and recognized as a member of the V. australis group, as defined by Bolton (1991). A lectotype is designated. In addition, the convoluted history of the two type specimens in the Forel Collection at the Muséum d'Histoire Naturelle, Genève, Switzerland is presented. An additional paralectotype specimen from the Museo Civico di Storia Naturale "Giacomo Doria", Genova, Italy is included.
