Taxon classification Animalia Hymenoptera Stephanidae

Foenatopus weii sp. n. Figs 1, 2-5, 6-11

Material examined.

Holotype, ♀ (SCAU), CHINA: Yunnan, Jinghong, Nanbanhe National Nature Reserve, 22°15'47.39"N, 100°36'3.22"E, 892 m, 19-23.VII.2011, Nasen Wei, yellow pan trap.

Etymology.

Named after the collector Dr. Nasen Wei.

Diagnosis.

Frons finely and transversely carinate-rugose (Fig. 2); vertex finely and transversely striate (Fig. 4); pronotum slender and mostly coriaceous, but anteriorly transversely rugulose (Figs 3, 5); scutellum (Fig. 5), propleuron and mesopleuron (Figs 3, 6) coriaceous; propodeum (Figs 5, 6) with medium-sized, circular foveolae and with coriaceous interspaces, inside of foveolae polished; fore wing with vein 2-CU1 absent (Fig. 9); most of mid tarsus ivory; subapical part of ovipositor sheath whitish (Fig. 11). This species is most similar to Foenatopus flavidentatus (Enderlein, 1913) but can be distinguished by the combination of the following characteristics: frons with two rather than three short longitudinal ivory streaks; pronotum entirely coriaceous (smooth posteriorly in Foenatopus flavidentatus ); propodeum more spaced foveolate (reticulate-foveolate in Foenatopus flavidentatus ); hind femur entirely black (hind femur chestnut brown and with two large ventral teeth yellowish in Foenatopus flavidentatus ).

Description.

Holotype. Female. Body length 12.2 mm; fore wing length 6.1 mm.

Colour. Black (Fig. 1), except: frons laterally with short ivory streaks not reaching level of anterior coronal tooth (Fig. 2); temple brown with ivory streak along lower half of the eye, streak becoming narrow apically (Fig. 3); base of mandible yellow; most of mid tarsus ivory; subapical part of ovipositor sheath whitish (Fig. 11).

Head. Antenna with 33 segments; first flagellomere 3.0 × as long as wide, and 0.6 × as long as second flagellomere; three anterior coronal teeth large and acute, both posterior ones short and wider; frons finely and transversely carinate-rugose (Fig. 2); coronal area with some longitudinal carinae; vertex finely and transversely striate (Fig. 4); temple non-angulate, smooth and shiny (Fig. 3).

Mesosoma. Pronotum (Figs 3, 5) slender and mostly coriaceous, but with transverse rugulae anteriorly; neck anteriorly deeply emarginated, neck at slightly lower level than middle part of pronotum (Fig. 3); anterior half of mesoscutum transversely coriaceous, posterior half with shallow and large foveolae; notauli and middle groove distinct; scutellum (Fig. 5), propleuron and mesopleuron (Figs 3, 6) coriaceous; propodeum (Figs 5, 6) with medium-sized, circular foveolae and with wide coriaceous interspaces, inside of foveolae polished; fore wing (Fig. 9) with vein 2-CU1 absent; pterostigma elongate and subparallel-sided, acute apically, 15.4 × as long as its maximum width and 3.1 × as long as vein r; vein r and vein SR1 obtusely-angled, vein r ends 0.2 × length of pterostigma behind level of apex of pterostigma; vein SR1 subparallel to costal margin; hind coxa transversely striate, basal third rugose; hind femur swollen, microreticulate, ventrally with two large acute teeth and with one smaller tubercle basally (Fig. 7); hind tibia coriaceous, 1.2 × as long as hind femur, basal narrow part of hind tibia 1.2 × as long as widened part, inner side of widened part basally distinctly depressed, followed by convex and setose area, apically densely setose.

Metasoma. First tergite transversely striate, 14.7 × as long as its maximum width, 3.5 × as long as second tergite and 1.1 × as long as remainder of metasoma; basal 0.1 of second tergite rugose, remaining tergites largely smooth to weakly coriaceous; pygidial area distinctly differentiated, pygidial impression reverse V-shaped; length of ovipositor sheath 0.7 × as long as body length, length of subapical whitish band 1.9 × length of dark apex (Fig. 11).

Male. Unknown.

Distribution.

Oriental: China (Yunnan).
