Londt, Jason G. H., 1983, The Genus Daspletis Loew, 1858 And The Description Of Two New Genera, Anasillomos And Remotomyia (Diptera: Asilidae: Stenopogoninae), Journal of the Entomological Society of Southern Africa 46 (2), pp. 283-308 : 295-296

Daspletis stenoura spec. nov. Figs 22-24 .

Derivation: Gr. Stems = narrow; oura = tail. Refers to the narrow gonocoxites.

Description: Agrees very closely with the description of D. hirtus except for the following points:

Head: A11 antennal segments orange. Mystacal bristles yellow-white.

Thorax: 4, supra-alar bristles. Legs: femora yellow-brown ventrally and distally on dorsal aspects. Wings: 83-93 mm long; 2,7—3,2 mm wide (in the northern Cape hirtus is generally a slightly larger species). Cell cup close to wing margin. Abdomen: d‘ genitalia as in Figs 22-24 ..

Variation: Only minor sexual dimorphism as in hirtus.

MATERIAL EXAMINED. SOUTH AFRICA: Cape Province: 10 ♂ (holotype and paratypes) 3 ♀ (paratypes), 30 km E. Groblershoop , 2822CD, 19.iii. 1982, J. Londt & L. Schoernan, roadside vegetation ( NM) ; 3♂ 4 ♀ (paratypes), Padkloof Pass ca. 20 km S. Witsand , Dry river course Grass/Acacias, 2822 DA, 17. iii. 1982, J. Londt & L. Schoeman ( NM) ; 4 ♀ (paratypes), 15 km SE Vanzylsrus, 2622CC, 22. iii. 1 9 82, L. Londt & L. Schoeman, Acacias Grass/Shrubs ( NM) ; 2 ♂ (paratypes), 55 km W. Vanzylsrus, 272 1 BA, 22.iii.19 82, J. Londt & L. Schoeman, Acacias/Dry Grass ( NM) ; ı ♀ (paratype), 50 km SW of Kuruman , 2723CA, 24.iii. 1 9 82, J. Londt & L. Schoernan, Acacia woodland area ( NM). NM Type no. 2655 .

Remarks: A species very similar to D. hirtus but male genitalia with narrow fused gonocoxites quite easily distinguished from those of hiríus. Females are difficult to separate but stenoura has bristles, especially those of the legs, somewhat yellower than in hirtus .
