Philotrypesis paiwan Li & Rasplus sp. nov. Figs 11 A, 11 C – F, 12 A – D (♀), 11 B, 12 E, F (♂) Type material. Holotype • 1 ♀: China, Taiwan, Kenting, Hengchun TBG [21.964 120.813], 8. ix. 2008, Cruaud A. & Rasplus J. Y. leg. [JRAS 02406_0201], deposited in CBGP, Montpellier. Condition: glued by right side on rectangular card; perfect state, entire. Paratypes: • 3 ♀, 1 ♂, same data as holotype. Paratype specimens deposited in CBGP, Montpellier. Diagnosis. Female recognised by the entirely yellow antennae, strongly alutaceous lower face and parascrobal area, antenna inserted distinctly above the ocular line, regularly convex clypeal margin, orange ventral metasoma, and densely sculptured mesoscutellum with elongate meshes and a median longitudinal declivity. The propodeum is distinctive in possessing winding submedian carinae and a median depression crossed by transverse septa. The ovipositor sheath slightly exceeds metasomal length and Mt 7 is moderately elongate, being about 1.0–1.1 × as long as Mt 8 + 9. Together with P. arfak sp. nov., it forms a distinctive subgroup characterized by an orange ventral metasoma, strong facial sculpture and a sculptured mesoscutellum. It differs from P. arfak sp. nov. by its entirely yellow antennae, denser mesoscutellar sculpture, more elaborate propodeal sculpture, shorter ovipositor sheath (about 1.2 × versus 1.4–1.5 × metasomal length) and less developed gastral tail (Mt 7 about 1.0–1.1 × versus 1.2–1.4 × the length of Mt 8 + 9). It differs from P. ravii, P. minang sp. nov. and P. bannaensis sp. nov. by the orange ventral metasoma, strongly sculptured lower face and sculptured mesoscutellum. Male recognised by the triangularly emarginate clypeal margin, 4 - segmented funicle with subdivided clava, large eyes (eye length about 0.8 × eye height), and extremely elongate pronotum (about 1.8 × as long as mesonotum + metanotum). Closest to P. arfak sp. nov., but differing by the much longer pronotum and mesonotum, and by the larger eyes. Female. Body length: 2.32–2.35 mm; ovipositor length: 1.61–1.66 mm.
