T. eirene Heydon, 2004: 184 –186; holotype in UCD, examined.

Diagnosis. Female (male unknown): flagellum uniformly brown on dorsal side, paler ventrally ( Figs 93, 95 ); legs uniformly pale ( Fig. 91 ); fore wing hyaline ( Fig. 99 ); body setation short (longest genal setae about 1/5 length of tegula) and whitish ( Figs 93, 95, 96, 99 ); head in profile with face only slightly convex at toruli level ( Fig. 95 ); eye height 1.55–1.80× length of malar space; eye in lateral view not distinctly inclined relative to vertical axis of head ( Fig. 95 ); lower margin of toruli slightly above or level with lower margin of eyes ( Fig. 93 ); antenna ( Figs 93, 95 ) with scape barely reaching median ocellus; clava width 1.1–1.5× width of F1; proximal funicular segments quadrate to slightly transverse, distal funicular segments slightly to moderately transverse (F5 width 1.1–1.5× length); mesosoma length about equal to width; MV length 2.0–2.5× width; fore wing speculum present, although small ( Fig. 99 ).

The females of T. eirene are very similar to those of T. africana (see diagnosis of the latter species).
