Introduction
The genus Condylostylus is a wide spread pantropical taxon. It
contains approximately 308 described species with a huge diversity
in Neotropical Region (230 species) and a small number of species in
southern Nearctic, far-eastern Palearctic and other Regions (Bickel,
1994). Twelve species of the genus occur throughout Africa south of
latitude 10 centigrades North including Madagascar. Probably a few
afrotropical species of Condylostylus await description.
The species of Condylostylus, contrary to that of other
sciapodine genera, are well recognized by strongly recurved vein M1,
four strong scutellar and five pairs of strong dorsocentral bristles,
and setose mound on the frons, bearing vertical seta. Males of
afrotropical species of the genus sometimes have abnormal wing
venation (C. pateraeformis Group), very narrow face and greatly
reduced hairs on the frontal mound (the same Group and C. burgeoni
Group), relatively short (C. paricoxa) or bifurcated (C. selectus)
cercus.
In this paper first descriptions of C. galinae sp.n. and male C.
paricoxa Parent, and new records for known species are given on the
basis of the collections from the Natural History Museum, London
(NHML), the Hungarian Natural History Museum (HNHM), and the Institut
Royal des Sciences Naturelles, Brussels (IRSN).
Holotype and paratypes of the new species, as well as a male of
C. paricoxa, are conserved in the Natural History Museum (London).
