Thaumatodryinus townesi Olmi, 1984: 692 (partim, only male).

Etymology: This species is named after the type locality, Sokoke Forest.

Description:

Male.

Fully winged; length 2.68 mm. Head black, with mandibles testaceous; antennae testaceous, with segments 3–10 darkened; prothorax testaceous; scutum black, with notauli and median region testaceous; rest of mesosoma black; gaster brown; legs testaceous.Antennae filiform; antennomeres as following: 6:6:9:12:11:12:11:10:8:10. Head dull, granulated and reticulate rugose; frontal line absent; occipital carina complete;

POL = 6; OL = 2; OOL = 6; OPL = 1; TL = 4. Scutum dull, granulated and slightly reticulate rugose. Notauli complete, posteriorly separated; minimum distance between notauli as long as POL, longer than greatest diameter of posterior ocelli (5:4), longer than breadth of lateral regions of scutum measured at posterior margin. Scutellum and metanotum shiny, smooth, without sculpture. Propodeum dull, reticulate rugose, without transverse or longitudinal keels. Forewing hyaline, without dark transverse bands; distal part of stigmal vein longer than proximal part. Inner side of parameres ( Fig. 13 ) without mosaic pattern. Tibial spurs 1, 1, 2.

Female. Unknown.

Holotype: ơ “ KENYA: Sokoke Forest , 8.v.1976, Ian Bampton”; [red] “ Thaumatodryinus sokokensis sp. n. M. Olmi det. 2005, ơ” (AEIC).

Hosts: Unknown.

Comparison: The male of T. sokokensis is similar to that of T. merinus Olmi, 2004 b , but the head is black, with only mandibles testaceous. By contrast, in T. merinus the head is extensively testaceous.

Remarks: T. townesi was described on the basis of both sexes. The male, however, was not reared, but tentatively associated to the female holotype according to the systematics of that time. Afterwards, T. townesi was attributed by Olmi (1990 b) to Pseudodryinus Olmi, 1990 . In fact, the female agrees with the morphologic characters of Pseudodryinus . On the contrary, the male does not agree, because the minimum distance between the notauli is longer than greatest diameter of posterior ocelli (in Pseudodryinus the minimum distance between the notauli is much shorter than breadth of the ocelli). For this reason, the male of T. townesi is now attributed to the new species, T. sokokensis .
