(Figs 3 A–G, 4A–G, 5G, 6G, 7G, 8F)
Type material. Holotype ♀: CHINA, Xishuangbanna Tropical Botanical Garden, 21°55′N, 101°15′E, H 547±7, 22.VIIII.2011, collected by Y. C. Ma, ex Ficus curtipes Corner, (I–1–12 –CEG ethanol collection number). Deposited in Xishuangbanna Tropical Botanical Garden, Chinese Academy of Sciences, Kunming, 88 Xuefu Road. Paratypes: 15 ♀, 4 ♂: same data as holotype; deposited with holotype.
Etymology. Named after its host fig tree, F. curtipes.
Diagnosis. Female (Figs 3 A, 5G, 6G): POL:OOL = 5:2; marginal vein more than twice as long as postmarginal vein. Male (Figs 4 A, 4C, 7A–G): head subquadrate, without posterior transverse groove (present in other six species); toruli with posterior margins connected by a groove (not connected by groove in W. jacobsoni); mandible larger and more massive than for other six species as in Fig. 7; fore wing (Figs 4 D, 8A–F) vestigial, nearly invisible, punctiform.
Affinities. Males of W. curtipedis uniquely share a subquadrate head with W. jacobsoni (Figs 7 B, 7G).
Description of female. Size and colour. Length 2.4 mm. Head, mesosoma, and all coxae and femora black with iridescent green, other parts of legs transparent yellow; metasoma black with distinct iridescent bluish-green tinge; eyes and ocelli dark red; antennal scape and anelli yellow, pedicel brownish-yellow, rest of antenna smokyblack; wings hyaline.
Head. Shape as in figure (Figs 3 A, 5G), 0.8× as long as wide, with distinct reticulated puncta on dorsum; eye a little longer than wide, about 0.85× as wide as long; antennae inserted close together in middle of dorsum of head; inter-torular distance about 0.2× oculo-torular distance, a little more than 0.6× diameter of torulus; antennal scrobe distinct and parallel; POL:OOL = 5:2. Antennal formula 11253 (Fig. 3 B); scape a little shorter than 6.5× as long as broad, cylindrical; pedicel about 1.5× as long as wide; flagellum with first two segments forming two small unequal anelli, flagellomeres 3–7 forming funicle, the segments wider than long, and flagellomeres 8–10 fused to form a club about twice its maximum width. Mandible (Fig. 3 C) a little less than 1.5× as long as wide, tridentate with three glands. Maxillary palpus (Fig. 3 C) 4-segmented (5:6:4:8); labial palpus (Fig. 3 C) 2-segmented (1:1).
Mesosoma. Closely reticulate-punctate. Pronotum narrow, a little over 3× as long as wide, anterior half vertical; mesonotum with mesoscutum about 0.6× as long as wide, sub-quadrangular; notauli complete; scutellum sub-circular, as long as mesoscutum. Fore wing (Fig. 6 G) about twice as long as wide; distal one-third slightly pubescent, marginal fringe short; submarginal, marginal, stigmal, and postmarginal veins approximately in ratio of 28:14:5:6; stigmal vein with four rounded sensilla distally as in Fig. 6 G. Hind wing about 3.5× as long as wide; marginal fringe long. Fore leg (Fig. 3 E) with coxa slightly more than 1.5× as long as wide; femur a little over 2.5× as long as wide, widest in middle; tibia slightly longer than coxa, a little more than 0.8× length of femur, and a little more than 4× as long as wide, with long setae, distally with two small spines on dorsal side and three odontoid spines and a long bifid apical spur on ventral side; tarsus about 0.8× length of tibia; basal tarsomere about one-third length of tarsus and about equal to following two tarsomeres combined. Mid leg (Fig. 3 F) with femur a little less than 4× as long as wide, widest in middle; tibia about 9× as long as wide, about equal in length to femur and trochanter combined, armed with numerous long setae and a long apical spur; tarsus slightly longer than femur, 0.8× length of tibia; basal tarsomere about 0.5× length of tarsus and about equal to following four tarsomeres combined. Hind leg (Fig. 3 G) with coxa a little less than twice as long as wide, reticulate-punctate dorsally; femur large, a little more than 2.5× as long as wide; tibia shorter than femur, about 4× as long as wide, with numerous long setae, a pair of unequal apical spurs and about 20 odontoid spines; tarsus about equal in length to coxa, about 0.8× length of tibia; basal tarsomere slightly shorter than half length of tarsus and about equal to following three tarsomeres combined.
Metasoma. Longer than mesosoma, a little longer than twice its height; tergites two and three with posterior margins usually deeply excised in middle; ovipositor sheaths protruding slightly.
Description of male. Size and colour. Length 2.4–3.0 mm. Head, mesosoma and all legs yellow, metasoma pale gray; mandibles reddish-brown; antennal scape brownish-yellow, pedicel yellow, flagellum gray; eyes black. Head (Figs 4 A, 7G). Head slightly shorter than wide, sub-quadrate; eye slightly less than twice as long as wide; clypeus deeply depressed, with several short setae, anterior margin concave, medially sharply convex; frons above antennae mesad large eyes distinctly striate, each stria isolated by many deep foveolae with one short seta, and rest of frons with some low foveolae; antennae inserted apart in middle of dorsum of head, with distance between toruli more than twice distance between torulus and eye; internal margins of toruli distinctly thickened, connected by a groove. Antennal formula 11152 (Fig. 4 B); scape gradually expanding in apical half, compressed, sub-clavate, about 3× its maximum width; pedicel 2.5× as long as wide; funiculars gradually shortened, the width of apical two funiculars similar; apical two flagellomeres forming a club twice as long as its maximum width. Mandible (Fig. 4 C) large and massive with many foveolae and one short seta, shorter than head, a little over 1.5× as long as wide; bidentate apically with ventral tooth massive and obtuse, and with two massive dentiform projections on its internal margin basally.
Mesosoma. Prothorax large. Pronotum sub-quadrangular and pubescent, about 1.5× as wide as long; mesonotum, metanotum and propodeum combined a little over 1.5× as wide as long. Fore wing (Figs 4 D, 8F) vestigial, nearly invisible, punctiform as in Fig. 4 D. Fore leg (Fig. 4 E) with coxa about 1.5× as long as wide, its outer side with many setae; femur large, slightly less than twice its maximum width, its ventral side with regular setae; tibia a little shorter than femur, sub-claviform, slightly more than 3× as long as wide, with long setae, spines, a long bifid spur and 15 odontoid spines; tarsus slightly shorter than 0.6× length of tibia, the apical tarsomere a little longer than the three preceding tarsomeres combined. Mid leg (Fig. 4 F) with coxa less than 1.5× as long as wide; femur a little shorter than twice as long as wide; tibia clavate, 4.5× as long as wide, slightly longer than femur, with numerous setae, spines, a long apical spur and 26 odontoid spines; tarsus a little longer than half length of tibia, 4-segmented, the apical tarsomere a little longer than first and second tarsomeres combined. Hind leg (Fig. 4 G) with coxa about 2.5× as long as wide; femur as long as coxa, 2.5× as long as wide; tibia longer than femur, but shorter than length of femur and trochanter combined, about 5× as long as wide, with setae, a pair of unequal apical spurs and 36 odontoid spines; tarsus longer than half length of tibia length, the apical tarsomere about equal to two preceding tarsomeres combined.
Metasoma. A little less than 1.5× as long as wide, depressed. Genital armature with two apically rounded dorsal appendages, each with four odontoid spines.
