Trigastrotheca trilobata Cameron, 1906

Figs 34 , 35

Diagnosis.

Similar to T. aethiopica sp. nov. and T. romani in being ochraceous except for black stemmaticum. Differs from T. aethiopica sp. nov. in having the pterostigma largely black, especially on the anterior 1 / 2, and from T. romani in that it has the frons anterolateral to median ocellus with distinct weakly diverging striae which is similar to the condition found in the male of T. serrata ( van Achterberg & Sigwalt, 1987) .

Notes.

The type species of Trigastrotheca is T. trilobata Cameron, 1906 from South Africa or Zimbabwe [ Rhodesia] ( Cameron 1906). The type label in Cameron’s handwriting states “ Cape ” (Fig. 32 A ), but on the underside of the card that the specimen is micro-pinned to with a minute pin “ Rhodesia ” and an illegible word is written (see http://www.waspweb.org/ichneumonoidea/Braconidae/Braconinae/Trigastrotheca/Trigastrotheca_trilobata.htm).
