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. burksimost 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).
Material examined. Typematerial. Holotype ♀(deposited in UCR) [entire except right front leg beyond trochanter missing; on triangular card]. D. R. CONGO: ‘Rep. Congo: Pool, Abio, Lesio-Louna Park, 3°6’1”S 15°31’26”E, 26.viii.2008 BraetMT’, ‘Univ. Calif. Riverside, Ent. Res. Museum, UCRCENT00229345’.
Description. Female. Body length: 1.4 mm. Colour.Head and mesosoma mainly brownish-black, with weak blue-green reflections ( Figs 82, 83); membranous area between pronotum and fore coxa whitish ( Fig. 89). Gaster brown ( Figs 82, 83). Eyes pale reddish-grey; ocelli whitish ( Figs 84, 85). Antenna ( Figs 86, 87) with scape light brown; pedicel and flagellum brown dorsally, light brown ventrally. Mandibles light brown, teeth reddish-brown ( Figs 84, 86). Legs ( Fig. 82) 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). Body setation whitish, wing setation brownish ( Figs 84, 86, 88, 90). FIGURES 82, 83. Teasienna burksi, holotype ♀: 82, habitus, lateral view; 83, ♀, habitus, dorsal view. FIGURES 84–90. Teasienna burksi, holotype ♀: 84, head, frontal view; 85, head, dorsal view; 86, head, lateral view; 87, antenna; 88, mesosoma, dorsal view; 89, mesosoma, lateral view; 90, fore wing. 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). Gaster. Short ovate, shorter than head plus mesosoma ( Figs 82, 83); length about 1.4× width (59:42). Male. Unknown.
Distribution. Democratic Republic of Congo.
Biology.Unknown.
Etymology.Named in honour of Dr. Roger Burks (UCR), for his contribution to the systematics of Chalcidoidea.
