Amemboa mahananda sp. nov. and Amemboa bifurcata sp. nov. are described from Mahananda Wildlife Sanctuary, in the Darjeeling district and from Kalikhola, in the Jalpaiguri district of West Bengal, and compared with all allied species. A species checklist of the genus Amemboa Esaki, 1925  and Amemboides Polhemus & Andersen, 1984 from India and their distribution in India and elsewhere is provide...

Although they are of economic importance, there have been few cytogenetic studies of the Gerridae (Heteroptera) in Brazil. We examined spermatogenesis (meiosis and spermiogenesis) and nucleolar behavior in three species of the family Gerridae. Brachymetra albinerva and Halobatopsis platensis were found to have a chromosome complement of 2n = 25 (24A + X0) and Cylindrostethus palmaris 2n = 29 (2...

Metrocoris morsei sp. nov., and Metrocoris shillongensis sp. nov., are described from India and compared with known congeners. Metrocoris morsei sp. nov. from Great Nicobar Biosphere Reserve (GNBR), Nicobar Islands, cannot be assigned to any of the known species groups of Metrocoris, so it forms the Metrocoris morsei-group. M. shillongensis sp. nov. from Shillong, Meghalaya, belongs to the M. o...

Tenagogonus venkataramani sp. nov. from Great Nicobar Biosphere Reserve (GNBR), Andaman and Nicobar Islands, India, is described and compared with allied species. Morphological notes on T. ceylonensis Hungerford and Matsuda, 1962, and T. nicobarensis Andersen, 1964, known from India, are presented along with distribution maps of these three Indian species.

The Everglades is a large subtropical wetland that has been modified heavily by humans and now undergoing restoration. Aquatic semiaquatic Heteroptera (Hemiptera) in the infraorders Gerromorpha Nepomorpha were collected Florida using standardized 1-m2 throw-traps. Sampling efforts conducted marshes distributed from southern National Park, north throughout Water Conservation Areas to Loxahatchee...
