Encarsia maculiformis , female: 16, fore wing; 17, stigmal vein; 18, mesosoma; 19, ovipositor. Description. Female. Holotype . Body length: 0.57 mm. Colour. Body mostly pale yellow. Head with mouth region dark brown, eyes dark grey, ocelli red-brown. Mandible brown ( Figs 12–14 ). Antenna pale yellow to dark yellow ( Fig. 15 ). Mesosoma with anterior margin of pronotum and lateral margin of axillae brown to dark brown; prosternum dark ( Figs 11, 12 ). Wings hyaline except fore wing faintly infuscate behind marginal vein ( Fig. 16 ). Legs white to pale yellow. Metasoma with petiole, anterior margin of T1, and T5 with transverse dark brown stripes; posteromedial margin of T1 and middle of T2–T4 with short transverse dark brown stripes forming ⊥ -shaped dark brown patch from petiole to T5 ( Fig. 11 ); gastral sternites anteromedially dark brown; third valvula pale yellow ( Fig. 12 ). Head. Frontovertex largely with transverse sculpture. Maxillary and labial palps 1-segmented. Mandibles with three teeth. Antennal formula 1:1:3:3; scape 4.12× as long as wide; pedicel equal in length to F2 (31: 31), longer than F1 (31: 21) and slightly shorter than F3 (31: 33); F1 shorter than each of flagellar segments, respectively; C1–C 3 in length as 38: 43: 55; flagellum with following numbers of longitudinal sensilla: F1: 0, F2: 1, F3: 1, F4: 2, F5: 2, F6: 2 ( Fig. 15 ). Mesosoma. Mid-lobe of mesoscutum smooth, posteromedially with 1+1 fine setae; side-lobe of mesoscutum with 2 setae; axilla with 1 seta; scutellum with 2 pairs of setae, fore pair of setae finer than and 0.33× as long as hind pair, distance between fore pair of setae slightly greater than between hind pair; placoid sensilla distantly placed, closer to fore pair than to hind pair of setae ( Fig. 18 ). Fore wing narrow, 3.17× as long as maximum width of wing disc; marginal fringe rather long, 0.73× as long as maximum width of disc; submarginal vein with 2 setae, anterior margin of marginal vein with 6 or 7 setae, basal cell with 1 seta; wing disc densely setose ( Fig. 16 ). Tarsal formula 5: 5: 5. Metasoma. Metasoma 1.31× as long as mesosoma; petiole laterally with fine sculpture; tergites 1–7 with setae as follows: T1, 0+0; T2–T5, 1+1 each; T6, 2 between cercal plates; T 7, 6 in two rows. Ovipositor short, basally located at apex of T4, not projecting beyond apex of metasoma, equal in length to mid tibia (65: 65) and shorter than mid tibia and basitarsus combined (65: 81); third valvula about 0.38× as long as second valvifer, and 1.13× as long as mid basitarsus ( Fig. 19 ). Male. Unknown. Species-group placement. Encarsia perflava -group. Host. Unknown whitefly ( Hemiptera : Aleyrodidae ) on Ficus microcarpa Linn. Distribution. China (Hainan). Etymology. The species name is derived from the Latin, maculiformis = patched, referring to the ⊥ -shaped dark brown patch on the metasoma. Diagnosis . Encarsia maculiformis sp. nov. is placed in the perflava group, and keys to couplet 63 in the key to Chinese Encarsia species given by Huang & Polaszek (1998) , but differs from all other species of perflava group in the following characters: metasoma with the distinctly ⊥ -shaped dark brown patch from petiole to T5 ( Fig. 11 ); mid-lobe of mesoscutum smooth, posteromedially with only 1+1 fine setae ( Fig. 18 ); antenna with F1 short, without longitudinal sensilla ( Fig. 15 ); fore wing narrow, 3.17× as long as maximum width of wing disc; marginal fringe rather long, 0.73× as long as maximum width of disc ( Fig. 16 ).
