Philotrypesis minang Li & Rasplus sp. nov. Figs 9 A, 9 C – F, 10 A – D (♀), 9 B, 10 E, F (♂) Type material. Holotype • ♀: Indonesia, Sumatra, Bukittinggi [-0.304929 100.358216] 6. iv. 1990 Tanjung P. [JRAS 06684_0202]. Condition: glued by right side on rectangular card; perfect state, entire. Paratypes • 13 ♀, 1 ♂, same data as holotype. All type specimens deposited at CBGP, Montpellier. Diagnosis. Female recognised by the weakly sculptured lower face and parascrobal area, antenna inserted above the ocular line, slightly convex clypeal margin, smooth mesoscutellum, dark ventral metasoma, and strongly developed gastral tail. The ovipositor sheath is remarkably long, about 1.3–1.5 × metasomal length, and Mt 7 is about 0.9–1.4 × as long as Mt 8 + 9. The propodeum bears complete submedian carinae and four conspicuous anterior carinae. It belongs to the dark-bodied subgroup (with P. ravii, P. minang sp. nov., P. bannaensis sp. nov.) sharing a smooth mesoscutellum and weak facial sculpture, but differs from P. ravii and P. bannaensis sp. nov. by its much longer ovipositor sheath (about 1.3–1.5 × versus less than metasomal length) and more strongly developed gastral tail (Mt 7 about 0.9–1.4 × versus 0.8 × and 1.0 × the length of Mt 8 + 9, respectively). Although approaching P. arfak sp. nov. in ovipositor length and tail development, it differs by the dark ventral metasoma, smooth mesoscutellum, weak facial sculpture and complete propodeal carination. Male recognised by the elongate head (longer than broad), very long vertex setae, 5 - segmented funicle with subdivided clava, and extremely elongate pronotum, nearly twice as long as the fused meso- and metanotum. Closest to P. paiwan sp. nov., but differing by the elongate head, 5 - segmented rather than 4 - segmented funicle, broadly emarginate rather than triangularly emarginate clypeus, and shorter mesonotum relative to propodeum.

The species was also reared from figs of Ficus tinctoria subsp. gibbosa (Blume) Corner, pollinated by an undescribed species of Kradibia (sp 046 in our database) closely related to Kradibia rutherforti subsp. rutherforti (Waterston, 1920).
