Teasienna burksi sp. nov.

(Figs 82–90)

Diagnosis. Female (male unknown): flagellum uniformly brown on dorsal side, paler ventrally (Figs 86, 87); legs with femora conspicuously dark (Fig. 82); fore wing hyaline (Fig. 90); body setation short (longest genal setae about 1/5 length of tegula) and whitish (Figs 84–86, 88); antenna (Figs 86, 87) strongly clavate, clava about twice as wide as F1; funicular segments strongly transverse; mesosoma length about equal to width.

The female of T. burksi most closely resembles those of T. eirene, from which it can be easily separated by the dark femora (Fig. 82) and strongly transverse funicular segments (Fig. 87).

Sculpture. Head and mesosoma smooth to finely coriaceous-alutaceous (Figs 84, 86, 88); gaster smooth.

Structure. Head. Longest genal setae about 1/5 length of tegula. Head in profile with face slightly convex at toruli level (Fig. 86). Lower margins of toruli below lower eye margins (Fig. 84). Scape reaching median ocellus. Antenna strongly clavate, clava 2.6× as wide as F1 (6.5:2.5) (Figs 86, 87). Eyes virtually round, inner margins slightly diverging ventrally (Fig. 84); eye in lateral view slightly inclined relative to vertical axis of head (Fig. 86). Head width 2.55× length in dorsal view (51:20) and about 1.3× height in frontal view (51:40). POL about 1.6× OOL (13:8). Eye height subequal to length (18:17) and equal to malar space (18:18). Scape length about 1.2× eye height (22:18). Head width 1.45× length of pedicel plus flagellum (51:35). F1 width 1.25× length (2.5:2.0); F5 width 2.75× length (5.5:2.0); clava length about 2.4× width (15.5:6.5).

Mesosoma. Scutellar spine small, hardly visible among dense setae (Fig. 88). Propodeum smooth, median carina very thin (Fig. 88). Fore wing (Fig. 90) with small speculum, otherwise completely setose; parastigma with hyaline break. Mesosoma length equal to width (50:50), width 1.25× height (50:40). Mesoscutum width about 2.8× length (50:18). Mesoscutellum length about 1.1× width (25:23). Propodeum length about 0.2× mesoscutellum length (6:25). Fore wing length about twice width (115:57). MV length 1.9× width (9.5:5.0); SV about 2.3× MV (22:9.5); PV about 3.3× MV (31.0:9.5).
