Gavryusin ( ZMUM ) . Remarks. New material collected from the Mezam Department of Cameroon , which is very close (about 70 km ) to the type locality of C. beckeri (Dschang city), stimulated the re-examination of the description of this species ( Speiser 1920 ). As it turned out, Speiser incorrectly described the fore leg of his species; i.e ., he named the modified basitarsus as tibia, and the simple tarsomere 2 as the basitarsus. In all other respects, C. beckeri male is identical with the holotype of C. congensis (examined; see Grichanov 1998 , 1999 ). Therefore, the latter species is placed in synonymy with the former species. No differences in the male genitalia of C. beckeri collected from Cameroon , Ethiopia and Kenya were found. Nevertheless, wing venation is distinctly different. Vein M 1 is straight, forming an almost straight line with M 2 in the material from Cameroon ; M 1 is slightly curved, forming distinct angle with M 2 in the material from Ethiopia (like those veins in Fig. 3E ); and M 1 has proximal stump vein in middle, also forming distinct angle with M 2 in the material from Kenya . These characters may indicate cryptic species, but at this time they are considered as intraspecific variation, which is sometimes found in other species of Sciapodinae . Distribution.
