Philotrypesis arfak Li & Rasplus sp. nov. Figs 13 A, 13 C – F; 14 A – D (♀); 13 B, 14 E, F (♂) Type material. Holotype • ♀: Indonesia: West Papua, road from Manokwari to Maruni [-0.925 134.044], 11. v. 2008, Cruaud A.; Ubaidillah R. & Rasplus J. Y. leg. [JRAS 02350_0310], deposited in MZB, Bogor. Condition: glued by right side on rectangular card; perfect state, entire. Paratypes: • 22 ♀, 28 ♂, same data as holotype. Paratype specimens deposited in MZB, Bogor and CBGP, Montpellier. Diagnosis. Female recognized by the alutaceous lower face and parascrobal area, antenna inserted on the ocular line, orange ventral metasoma extending dorsally above the midline of the gaster, weakly sculptured mesoscutellum with a broad median longitudinal declivity, and long ovipositor sheath. The propodeum is distinctive in possessing discontinuous submedian carinae and only two conspicuous anterior carinae. The gastral tail is the most strongly developed within the P. ravii sp. gp., with Mt 7 about 1.2–1.4 × as long as Mt 8 + 9. Together with P. paiwan sp. nov., it belongs to the subgroup characterized by strong facial sculpture, orange metasomal coloration and a sculptured mesoscutellum. It differs from P. paiwan sp. nov. by its weaker mesoscutellar sculpture, simplified propodeal ornementation, markedly longer ovipositor sheath (about 1.4–1.5 × versus 1.2 × metasomal length) and more elongate gastral tail (Mt 7 about 1.2–1.4 × versus 1.0–1.1 × the length of Mt 8 + 9). Although approaching P. minang sp. nov. in ovipositor length and tail development, it differs by the orange metasoma, sculptured face and mesoscutellum, and reduced propodeal carination. Male recognised by the triangularly emarginate clypeal margin, long malar space (0.5–0.8 × eye height), long temples (3.3–4.0 × eye height), 4 - segmented funicle with a 3 - segmented clava, and pronotum only moderately longer than the mesonotum + metanotum (1.1–1.6 ×). Closest to P. paiwan sp. nov., but differing by the shorter pronotum, smaller eyes (eye length only 0.5–0.6 × eye height), and less elongate mesonotum relative to propodeum. Female.
