Philotrypesis ravii (Priyadarsanan, 2000) comb. nov. Figs 5 A, 5 C – F, 6 A – D (♀), 5 B, 6 E, F (♂) Philoverdance ravii Priyadarsanan, 2000: 80–81. Holotype ♀ [MZDC], not examined. Type data: India, Calicut, 4. ii. 1993; reared from figs of Ficus subsp. gibbosa (Blume) Corner [Terega (= Sycidium)] (Berg and Corner 2005; Pederneiras et al. 2015). Philoverdance ravii: Pramanik & Dey, 2016: SI. Type material. India: • Calicut [Holotype ♀, MZDC]. Distribution. India [Oriental]. Host Ficus. F. tinctoria subsp. parasitica [Terega (= Sycidium)]. Series ♀ ♂, Calicut, coll. Priyadarsanan D. R., 4. ii. 1993; 6 paratypes and 6 paratypes mounted on slides. (not examined). Additional material examined. • 67 ♀, 62 ♂: India: Karnataka, Agumbe [13.5184 75.0898] 2. ii. 2024 and ii. 2005, Kjellberg F., ex F. tinctoria (JRAS 01214_02 and JRAS 01221_03 respectively) (CBGP). Diagnosis. Female recognised by the weakly sculptured lower face and parascrobal area, antenna inserted just above the ocular line, straight clypeal margin, smooth mesoscutellum, dark ventral metasoma, and short ovipositor sheath, shorter than metasoma. The gastral tail is the shortest within the sp. gp., with Mt 7 about 0.8 × as long as Mt 8 + 9. It belongs to the subgroup comprising P. ravii, P. minang sp. nov. and P. bannaensis sp. nov., characterized by a dark ventral metasoma, weak facial sculpture and a smooth mesoscutellum. It is closest to P. bannaensis sp. nov., but differs by its broader Mt 7, and slightly longer ovipositor sheath. It differs from P. minang sp. nov. by its much shorter ovipositor sheath (less than metasomal length versus about 1.3–1.5 × metasomal length) and by its less developed gastral tail (Mt 7 about 0.8 × versus 0.9–1.4 × the length of Mt 8 + 9). Male recognised by the broadly emarginate clypeal margin, 5 - segmented funicle with undivided clava, and short pronotum, only about as long as the fused meso- and metanotum (1.0–1.2 ×). Closest to P. bannaensis sp. nov., but differing by the shorter pronotum, less punctate frontovertex, longer mesonotum relative to propodeum (1.6–1.9 × versus 1.2–1.3 ×), and shorter fore wing remnants. Female. Body length: 1.54–1.90 mm; ovipositor length: 0.95–1.09 mm.
