Length of body 3.1 mm, fore wing 2.8 mm. COLOURATION. Black; antenna dark brown except scapus and pedicellus yellow; clypeus reddish brown; mandible yellowish and with reddish teeth; prothorax yellow; first metasomal tergite and second tergite medio-anteriorly white; metasoma ventrally white or ivory; fore and middle legs brownish yellow except coxa, trochanter and tibia basally whitish; hind coxa and trochanter ivory, femur and tarsus brownish yellow, hind tibia dark brown but basally white; wing veins and parastigma pale brown, pterostigma dark brown. HEAD. Width 1.4 × median length in anterior view and part of head above eye in lateral view 0.2× height of eye; antenna with 41 segments and 1.6× as long as fore wing, not widened but shortened medially, gradually narrowing apically, subapical segments non-moniliform and longer than wide, third, fourth, tenth, fifteenth and penultimate segments 4.3, 4.0, 1.7, 1.3 and 2.0× as long as wide in lateral view, respectively; area of stemmaticum transversely striate; OOL: OD: POL=21: 6: 7; length of eye 1.0 × temple in dorsal view; frons transversely rugulose and with median carina; vertex reticulate-rugose with short setae; temple finely punctate and shiny; face rugulose and with distinct median ridge, dorsally connected to median carina; clypeus finely punctate and with shiny interspaces, truncate medio-ventrally; eye width in lateral view 0.9× maximum width of temple, eye height in anterior view 0.7× minimum width of face; malar space finely punctate and 1.1× as long as basal width of mandible; mandible somewhat slender, lower tooth of mandible 0.4× as long as apical tooth; face width equal to height of face and clypeus together. MESOSOMA. Length 1.4× its width in lateral view; side of pronotum superficially punctate-rugulose; mesoscutum densely and finely reticulate except distinctly coarsely reticulate medio-posteriorly; notauli absent; scutellar sulcus with four crenulae; scutellum reticulate; mesopleuron coarsely reticulate and without smooth and shiny area posteriorly, precoxal sulcus absent; propodeum reticulate, without median carina, with irregular transverse carina connected to four weak and blunt lateral tubercles. WINGS. Fore wing 3.6× as long as its maximum width; second submarginal cell petiolate; vein m-cu distinctly postfurcal; veins r and 1-SR+M straight; vein SR1 curved; vein 1-R1 as long as pterostigma; vein r issued far beyond middle of pterostigma, 0.9× vein r-m; r:2-SR: SR1= 9: 26: 45; vein 1-CU1 0.2× as long as vein 2-CU1. Hind wing: M+CU: 1-M: 1r-m =33: 45: 22. LEGS. Hind femur 3.6× as long as wide; longest spur of hind tibia 0.5× as long as its basitarsus; hind leg smooth and shiny except fine and superficial punctation; middle tibia without ivory blister. METASOMA. Oval in dorsal view, carapace 1.9 × as long as wide and 1.1 × as long as mesosoma; first to third tergites densely reticulate-rugose; third tergite 0.9× as long as second tergite, medial length of third tergite 0.6 × its maximum width; lamella of third tergite not protruding medio-apically and with pair of blunt tubercles latero-apically. VARIATION. Second submarginal cell weakly petiolate or rarely sessile; length of fore wing of female 2.5– 2.9 mm; antenna of female with 41–43 segments; mesoscutum medio-posteriorly, scutellum distally, mesopleuron dorsally and metapleuron more or less yellowish brown; third antennal segment basally more or less yellowish. Male Very similar to female, but second metasomal tergite black without yellow patch medio-anteriorly and first metasomal tergite yellow with black patch small or widened medially. Host Unknown. Distribution China (Hainan, Yunnan). Remarks Phanerotomella rugifera sp. nov. is similar to P. varicolorata Zettel, 1989 because of the distinctly developed vein 2-SR, the blackish brown metasoma except for the first tergite and the second tergite medio-basally yellow, the length of the fore wing 2.8–3.1 mm, and the eye in lateral view 0.9× as long as the temple. However, P. rugifera can be distinguished from P. varicolorata by the black head (yellowish brown in the latter), the mesoscutum being medially coarsely reticulate (finely reticulate in the latter), and the scutellar sulcus with four large crenulae (five small crenulae in the latter).
