Abstract
MORALES-CASTANO, Irina T. and MOLANO-RENDON, Fredy. Revision of the genera Eurygerris and Tachygerris (Hemiptera: Tachygerrini) from the neotropical region. Rev. Mex. Biodiv. [online]. 2009, vol.80, n.2, pp.395-410. ISSN 2007-8706.
The taxonomy of the tribe Tachygerrini (Hemiptera: Gerridae: Gerrinae) was studied. The tribe comprises 2 genera: Eurygerris Hungerford and Matsuda (with 10 species) and Tachygerris Drake (with 7 species). The revision was based on the examination of 19 entomological collections in the neotropics. The type materials of T. opacus, T. quadrilineatus, T. adamsoni, T. dentiferus, E. fuscinervis, E. flavolineatus, E. mexicanus and E. atrekes were reviewed. Eleven species from the tribe were re-described for the Neotropics, Tachygerris opacus, T. quadrilineatus, T. celocis, T. adamsoni, T. dentiferus, Eurygerris fuscinervis, E. flavolineatus, E. mexicanus, E. beieri, E. summatis, and E. atrekes. Eurygerris kahli (Drake y Harris, 1934) is synonymized with Eurygerris fuscinervis (Berg, 1898). Re-descriptions, illustrations, nomenclatural information and distribution and ecological data for each of the species are also provided. The geographical distributions for T. adamsoni (Venezuela), E. fuscinervis (Guatemala, Mexico and Venezuela), and E. atrekes (Venezuela) are expanded.
