title: Simulium (Edwardsellum) rasyani n.sp., the Yemen species of the Simulium damnosum complex.
abstract: The examination of the polytene chromosomes of the Yemen representative of the Simulium damnosum complex revealed hitherto unknown arrangements distinct enough to justify the description of this form as the new species Simulium (Edwardsellum) rasyani. The newly recognized inversion II L-60.65 was always present and found to be homozygous in 62% and heterozygous in 38% of the 106 larvae which were examined. A short description is given of the morphology of the females, males, larvae and pupae. Populations from the five permanent Wadis Kabir, Rasyan, Al Barh, Zabid, and Surdud were genetically and morphologically very uniform.
