Teasienna burksi sp. nov.

( Figs 82–90 View FIGURES 82, 83 View FIGURES 84 – 90 )

Diagnosis. Female (male unknown): flagellum uniformly brown on dorsal side, paler ventrally ( Figs 86, 87 View FIGURES 84 – 90 ); legs with femora conspicuously dark ( Fig. 82 View FIGURES 82, 83 ); fore wing hyaline ( Fig. 90 View FIGURES 84 – 90 ); body setation short (longest genal setae about 1/5 length of tegula) and whitish ( Figs 84–86, 88 View FIGURES 84 – 90 ); antenna ( Figs 86, 87 View FIGURES 84 – 90 ) 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 View FIGURES 82, 83 ) and strongly transverse funicular segments ( Fig. 87 View FIGURES 84 – 90 ).

Description. Female. Body length: 1.4 mm.

Colour. Head and mesosoma mainly brownish-black, with weak blue-green reflections ( Figs 82, 83 View FIGURES 82, 83 ); membranous area between pronotum and fore coxa whitish ( Fig. 89 View FIGURES 84 – 90 ). Gaster brown ( Figs 82, 83 View FIGURES 82, 83 ). Eyes pale reddish-grey; ocelli whitish ( Figs 84, 85 View FIGURES 84 – 90 ). Antenna ( Figs 86, 87 View FIGURES 84 – 90 ) with scape light brown; pedicel and flagellum brown dorsally, light brown ventrally. Mandibles light brown, teeth reddish-brown ( Figs 84, 86 View FIGURES 84 – 90 ). Legs ( Fig. 82 View FIGURES 82, 83 ) with coxae brown; trochanters pale yellow; femora brown except for pale yellow tips; tibiae pale yellow; tarsi pale yellow except for brown pretarsi. Wings hyaline, tegula and venation brown ( Fig. 90 View FIGURES 84 – 90 ). Body setation whitish, wing setation brownish ( Figs 84, 86, 88, 90 View FIGURES 84 – 90 ).

Sculpture. Head and mesosoma smooth to finely coriaceous-alutaceous ( Figs 84, 86, 88 View FIGURES 84 – 90 ); 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 View FIGURES 84 – 90 ). Lower margins of toruli below lower eye margins ( Fig. 84 View FIGURES 84 – 90 ). Scape reaching median ocellus. Antenna strongly clavate, clava 2.6× as wide as F1 (6.5:2.5) ( Figs 86, 87 View FIGURES 84 – 90 ). Eyes virtually round, inner margins slightly diverging ventrally ( Fig. 84 View FIGURES 84 – 90 ); eye in lateral view slightly inclined relative to vertical axis of head ( Fig. 86 View FIGURES 84 – 90 ). 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 View FIGURES 84 – 90 ). Propodeum smooth, median carina very thin ( Fig. 88 View FIGURES 84 – 90 ). Fore wing ( Fig. 90 View FIGURES 84 – 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).

Gaster. Short ovate, shorter than head plus mesosoma ( Figs 82, 83 View FIGURES 82, 83 ); length about 1.4× width (59:42).
