Abstract

Angilia Stål, 1865 is one of three genera of the subfamily Veliinae (Hemiptera: Heteroptera: Veliidae) from the Eastern Hemisphere and is distributed in sub-Saharan Africa, Madagascar, and Southeast Asia. Currently, 23 species and five subspecies are known and the genus is divided into two subgenera: Angilia ( Angilia ) Stål, 1865 and A . ( Adriennella ) Poisson, 1942. We present here the descriptions of two new species from Africa: A . ( An. ) morogoro n. sp. , from Tanzania, and A. ( Ad. ) igniventris n. sp. , from Madagascar. In addition, we propose A. ( An. ) albidotincta ugandensis Poisson, 1955 as a junior subjective synonym of A. ( An. ) a. albidotincta (Stål, 1855); A. ( An. ) kaokoveldi Poisson, 1958a as a junior objective synonym and junior homonym of A . ( An .) kaokoveldi Poisson, 1957; A . ( An .) albidotincta kaokoveldi Poisson, 1958b as a junior subjective synonym and junior homonym of A . ( An .) kaokoveldi Poisson, 1957; A . ( An .) collarti Poisson, 1958a as a junior objective synonym and junior homonym of A . ( An .) collarti Poisson, 1957; transfer Angilia perplexa Poisson, 1942 from the subgenus Adriennella to Angilia s. str .; and provide morphological notes and illustrations for the following species: A . ( An .) aeterna Hoberlandt, 1946, A. ( An. ) albidotincta , A. ( An. ) ambakakae Poisson, 1952, A. ( An. ) congoensis Poisson, 1950, A . ( An .) kaokoveldi , A. ( An. ) rhodesiensis Poisson, 1955, A. ( Ad. ) anderseni Zettel & Hecher, 1998, A. ( Ad. ) bertrandi Poisson, 1963, A. ( Ad. ) bispinosa Andersen, 1981, A. ( Ad. ) conradsi Poisson, 1950, A. ( Ad. ) orientalis Andersen, 1981, A. ( Ad. ) philippiensis Drake & Hoberlandt, 1953, and A. ( Ad. ) schoutedeni schoutedeni Poisson, 1942. We also designate lectotypes for three species and present a checklist and key to the species.
