New combinations and synonymies for Neotropical species of Diaphorinae (Diptera: Dolichopodidae).

Abstract

Based on examination of the Dolichopodidae (Diptera) material in the Senckenberg Naturhistorische Sammlung Dresden, eight Neotropical species of Diaphorus Meigen are herein transferred to the genus Chrysotus Meigen: C. amicus (Parent), comb. n.; C. ciliatus (Becker), comb. n. (= C. superbiens (Parent), comb. n. et syn. n.); C. hamatus (Parent), comb. n.; C. vicinus (Becker), comb. n., nec Parent; C. luteipalpus (Parent), comb. n.; C. mediotinctus (Becker), comb. n.; C. propinquus (Becker), comb. n. Additionally, C. kallweiti Capellari & Amorim, nom. n. is proposed as a replacement name for C. vicinus Parent, nec C. vicinus (Becker), comb. n., and C. diligens Parent is found to be a junior-synonym of C. viridis Becker. Lectotype and paralectotypes are designated for species with syntypes in their type-series. The mediotinctus-group is proposed within Chrysotus for a small clade including five South American species, and an identification key to the species of the group is provided.
