On the identities of Paracacoxenus exiguus (Duda) and Paracacoxenus inquilinus (Hendel), with the description of a new Paracacoxenus species from Italy (Diptera, Drosophilidae)


Bächli, G; Vilela, C R (2011). On the identities of Paracacoxenus exiguus (Duda) and Paracacoxenus inquilinus (Hendel), with the description of a new Paracacoxenus species from Italy (Diptera, Drosophilidae). Schweizerische Entomologische Gesellschaft. Mitteilungen, 84:113-139.

Abstract

Three male paralectotypes of Cacoxenus exiguus Duda, 1924 and the male holotype of Cacoxenus inquilinus Hendel, 1933, once considered to be lost, are examined. It is concluded that the latter binomial is a junior synonym of the former, which has precedence. So, the four specimens are re-described as Paracacoxenus exiguus. The subgenus Paracacoxenus is re-elevated to generic rank. Additionally, Paracacoxenus sp. aff. kaszabi sp. nov., a species closely related to P. kaszabi, is described from specimens mostly collected at Parco Nazionale dello Stelvio, Bolzano province, Trentino-Alto Adige region, Italy. Photomicrographs and drawings of their male terminalia are also included.
