Oratostylum Ricardo, 1925  

Oratostylum Ricardo, 1925: 260   . Type species: O. lepidum Ricardo 1925: 261   , by original designation.

I have examined Ricardo's type material of O. lepidum   in the BMNH and, as Hull (1962) gives such a good description of this monotypic genus, I merely present drawings of the male genitalia for comparative purposes ( Figs 32- 34 View Figs 31-34 ). Oratostylum   is very similar to Remotomyia   but has a very prominent facial swelling ( Fig. 31 View Figs 31-34 ) unlike that found in Remotomyia   ( Fig. 36 View Figs 35-39 ). Oratostylum lepidum   has long palps which reach the level of the lower facial margin whereas Remotomyia   species usually have shorter palps (in the case of R. longipalpus   they are long).

MATERIAL EXAMINED. ZIMBABWE; 1 ♂ (lectotype), Matopos , 3. x. 19 2 0, Rhodesian Museum ( BMNH)   ; 1 ♀ (paralectotype), Forestvale , 2 0.viii..1922, Rhodesian Museum ( BMNH)   ; 1 ♀ (paralectotypc), Bulawayo , 7. ix. 19 23, R. Stevenson ( BMNH)   ; 1 ♀, Khami Ruins , ı 8. viii. 1923, Rhodesian Museum ( BMNH)   . NAMIBIA: 1 ♀, Damaraland, Okombahe area 22 km W Uis Mine , 6. ii. 19 74, M. E. Irwin, 830 m, gravel plain ( NM)   . SOUTH AFRICA: Natal: 2 ♂, Lebombo foothills 5 km N Josini , 2732AC, 28. viii. 1982, under fig tree, B. Stuckenberg ( NM)   . Ricardo (1925) did not designate a holotype; I therefore designate the ♂ from Matopos as lectotype and the other specimens mentioned by Richardo as paralectotypes. The ♂ from Forestvale and ♂ from Umguza River are no longer in the BMNH.
