Teasienna heratyi  sp. nov.

( Figs 111–120View FIGURES 111, 112View FIGURES 113 – 120)

Diagnosis. Female (male unknown): flagellum progressively lighter towards pale yellow clava ( Figs 115, 120View FIGURES 113 – 120); fore wing uniformly and broadly infumate ( Figs 111View FIGURES 111, 112, 119View FIGURES 113 – 120); body setation long (longest genal setae about 1/2 length of tegula) and brown ( Figs 113–116View FIGURES 113 – 120); antenna ( Figs 115, 120View FIGURES 113 – 120) strongly clavate, clava about twice as wide as F1; funicular segments strongly transverse; mesosoma length about 1.3× width.

Teasienna heratyi  can be easily separated from all previously described species, mostly by the conspicuously and broadly infumate fore wings ( Figs 111View FIGURES 111, 112, 119View FIGURES 113 – 120), long brown body setae ( Figs 113–116View FIGURES 113 – 120), lighter colouration of the head, mesosoma and clava ( Fig. 111View FIGURES 111, 112, 120View FIGURES 113 – 120), and larger body size of females. Additionally, from T. eirene  it differs mainly in having the antenna much more strongly clavate, with the distal funicular segments strongly transverse ( Figs 115, 120View FIGURES 113 – 120).

Description. Female. Body length: 2 mm.

Colour. Head dark brown except clypeus and malar region lighter ( Figs 113–118View FIGURES 113 – 120). Mesosoma dorsally dark brown except pronotum and propodeum lighter ( Figs 116, 118View FIGURES 113 – 120); membranous area between pronotum and fore coxa whitish ( Fig. 117View FIGURES 113 – 120); mesopleuron ( Fig. 117View FIGURES 113 – 120) with upper mesepisternum dark brown, lower mesepisternum and mesepimeron lighter. Gaster brown, paler ventrally ( Figs 111, 112View FIGURES 111, 112). Eyes and ocelli whitish ( Fig. 114View FIGURES 113 – 120). Antenna ( Figs 115, 120View FIGURES 113 – 120) with scape, pedicel and anelli light brown; F1 brown, the following funicular segments progressively lighter towards pale yellow clava. Mandibles light brown, teeth reddish-brown ( Fig. 113View FIGURES 113 – 120). Legs ( Fig. 111View FIGURES 111, 112) with coxae and femora light brown; trochanters, tibiae and tarsi, except for brown pretarsi, pale yellow. Wings uniformly infumate, tegula and venation brown ( Figs 111View FIGURES 111, 112, 119View FIGURES 113 – 120). Body and wing setation brown ( Figs 113–116, 119View FIGURES 113 – 120).

Sculpture. Head and mesosoma smooth to finely coriaceous-alutaceous ( Figs 113–116View FIGURES 113 – 120); gaster smooth.

Structure. Head. Longest genal setae about 1/2 the length of tegula. Head in profile with face slightly convex at toruli level ( Fig. 115View FIGURES 113 – 120). Lower margins of toruli below lower eye margins ( Fig. 113View FIGURES 113 – 120). Scape reaching median ocellus ( Fig. 113View FIGURES 113 – 120). Antenna strongly clavate, clava twice as wide as F1 (9.0:4.5) ( Figs 115, 120View FIGURES 113 – 120). Eyes oval, inner margins subparallel ( Fig. 113View FIGURES 113 – 120); eye in lateral view not distinctly inclined relative to vertical axis of head ( Fig. 115View FIGURES 113 – 120). Head width 2.65× length in dorsal view (53:20) and about 1.2× height in frontal view (53:44). POL about 1.3× OOL (12:9). Eye height about 1.3× length (24:19) and 1.6× malar space (24:15). Scape length about 1.2× eye height (28:24). Head width 1.15× length of pedicel plus flagellum (53:46). F1 width about 1.3× length (4.5:3.5); F5 width about 1.8× length (8.0:4.5); clava length about 1.4× width (13:9).

Mesosoma. Scutellar spine large, but hardly visible among dense setae ( Fig. 116View FIGURES 113 – 120). Propodeum ( Fig. 118View FIGURES 113 – 120) smooth, median carina very strong; spiracles very large, oval. Fore wing ( Fig. 119View FIGURES 113 – 120) with very small speculum (effaced by setae on ventral side of the wing), otherwise completely setose; parastigma with hyaline break. Mesosoma length about 1.3× width (58:45), width 1.15× height (45:39). Mesoscutum width 2.25× length (45:20). Mesoscutellum length subequal to width (25:24). Propodeum length about 0.4× mesoscutellum length (9:25). Fore wing length about 2.3× width (150:65). MV length about 2.9× width (13.0:4.5); SV about 1.9× MV (25:13); PV about 3.4× MV (44:13).

Gaster. Short ovate, about as long as head plus mesosoma ( Figs 111, 112View FIGURES 111, 112); length 1.65× width (73:44).
