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).
