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.

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.

A review of the Philippine species of Odontomachus treats eleven species including two unnamed species. They belong to four species groups, Odontomachus simillimus SMITH, 1858 to the O. haematodus group, O. rixosus SMITH, 1857 to the newly delimited O. rixosus group, and O. malignus to the newly established O. malignus group (excluded from the O. infandus group). None of these three species are endemic. The majority of species belongs to the O. infandus group, and all known species are endemic to the Philippines. These include O. infandus SMITH, 1858 (= O. infandus r. striaticeps STITZ, 1925) from Luzon and Mindoro, O. philippinus EMERY, 1893 sp.rev.from Panay, Negros and Siquijor, O. banksi FOREL, 1910 from Luzon, and three species new to science: Odontomachus schoedli sp.n.from northern Luzon, O. alius sp.n., wide-spread in the central and eastern Philippines, and O. scifictus sp.n.from Camiguin. In addition, we treat two species (sp. 1 and sp. 2) of uncertain status from southern Luzon and Mindanao which remain unnamed. For stability of nomenclature, lectotypes are designated for O. infandus SMITH, 1858, O. infandus r. striaticeps STITZ, 1925, O. papuanus st. philippinus EMERY, 1893, and O. banksi FOREL, 1910.
