Trigastrotheca nigricornis Cameron, [1909] 1910

Figs 29 , 30

Notes.

The holotype female from South Africa (Cape Colony) is in the MFN but is too badly eaten by dermestids ( Shenefelt 1978) to permit species-level identification, and it is therefore not included in the key. However, the original description is fairly complete for the time and includes the following diagnosis for distinguishing it from T. trilobata : “ May be known from the type species of the genus, T. trilobata, Cam. (Ann. S. Afr. Mus., V, 32), by the shorter ovipositor (4 mm with a body length of 5 mm in the latter), by the middle lobe on the apex of the abdomen being hardly developed and by the 1 st abscissa of the radius being longer, not shorter, than the 2 nd. ”
