Diagnosis
Propleuron slender and 1.3–1.6 times as long as mesoscutum in front of tegulae (Fig. 253); head conically narrowed behind eyes (Fig. 257), truncate medio-posteriorly or nearly so; vertex very superficially punctulate and with satin sheen (Fig. 257); malar space 0.1–0.3 times as long as second antennal segment (= pedicellus); clypeus at most with a small depression (Figs 256, 262); apical antennal segment at most 1.2 times as long as third antennal segment and its colour similar to colour of medial segments; hind basitarsus comparatively long and narrow (Fig. 255); interspaces of mesoscutum more or less irregularly coriaceous and without punctures or densely transversely rugulose or rugose; hind tibia about 1.2 times as long as hind femur and trochanter and less swollen (Fig. 255); median carina of propodeum absent (but sometimes a slightly elevated smooth median line), if present then surrounding reticulate-rugose and carina similarly developed; ovipositor sheath 1.6–1.7 times as long as hind tibia and tarsus combined, 0.7–0.8 times as long as metasoma and 2.6–2.7 times as long as hind tibia; apical 0.1 of hypopygium incised; occipital carina obsolescent to narrowly lamelliform medio-dorsally (Fig. 252); apex of ovipositor sheath black or dark brown.
Description
Holotype, female, body length 12.8 mm, of fore wing 5.5 mm.
Head. Head gradually narrowed behind eyes and indistinct curved laterally (Fig. 257); temple 0.9 times as long as eye in dorsal view; vertex and frons matt and coriaceous; vertex flat without any depression medio-posteriorly; occipital carina undeveloped and non-lamelliform medio-dorsally (Fig. 252); third antennal segment 1.3 times as long as second segment; fourth antennal segment as long as third segment; fifth antennal segment 0.8 times as long as third segment (Fig. 259); eye setose; OOL 2.0 times as long as diameter of posterior ocellus; minimum width of malar space 0.2 times as long as second antennal segment; clypeus without depression.
Mesosoma. Length of mesosoma 2.1 times as long as its height; propleuron slender (Fig. 253), 1.3 times as long as mesoscutum in front of tegulae; side of pronotum reticulate-rugose to reticulate, with a distinct antero-lateral tooth; the whole mesoscutum coarsely reticulate-rugose, interspaces coriaceous (Fig. 254); scutellum punctate-rugose; propodeum reticulate, medio-longitudinal carina distinct.
Wings. Fore wing: first discal cell parallel-sided and with outer posterior corner rounded (Fig. 258).
Legs. Hind coxa satin sheen, moderately slender and dorsally reticulate-rugulose to transversely rugose; length of hind femur, tibia and basitarsus 3.3, 3.9 and 5.5 times their width, respectively (Fig. 255); middle tarsus 1.2 times as long as middle tibia.
Metasoma. Ovipositor sheath 0.5 times as long as body, 0.8 times as long as metasoma, 2.7 times as long as hind tibia and 1.6 times as long as hind tibia and tarsus combined; hypopygium shallow v-shaped incised apically.
Colour. Black; mandible dark brown; antenna black to dark brown; wing membrane subhyaline, pterostigma and veins brown; fore and middle legs dark brown to brown, but base of tibiae and basitarsi pale; basal 0.4 of hind tibia ivory ventrally; metasoma dark brown ventrally; ovipositor sheath entire black.
Male (described after a male from Fujian). Body length 11 mm; head gradually narrowed behind eyes (Fig. 260); temple as long as eye in dorsal view; vertex and frons with satin sheen and coriaceous (Fig. 260); vertex flat without any depression medio-posteriorly; occipital carina narrow and non-lamelliform medio-dorsally; third antennal segment 1.4 times as long as second segment; fourth antennal segment 0.9 times as long as third segment; fifth antennal segment 0.8 times as long as third segment (Fig. 264); eye setose; propleuron 1.5 times as long as mesoscutum in front of tegulae; side of pronotum mainly reticulate, with a distinct antero-lateral tooth; the whole mesoscutum densely reticulate-rugose, interspaces coriaceous; scutellum punctate-rugose (Fig. 261); hind coxa with satin sheen, moderately slender and dorsally transversely rugose; length of hind femur, tibia and basitarsus 4.1, 3.8 and 5.6 times their width (Fig. 263); the antenna brown; the colour of legs than female shallow; especially metasoma brown.
Variation. Female: the paratypes have no obvious differences. Body length 13–14 mm, ovipositor sheath 0.5 times as long as body, 0.7–0.8 times as long as metasoma, 2.6–2.7 times as long as hind tibia and about 1.6–1.7 times as long as hind tibia and tarsus combined.
Distribution
Oriental China (Fujian, Hainan, Yunnan).
Biology
Unknown. Collected in April, May and July.
Etymology
Named after the elongate propleuron (Latin: “strigosus” = “lean, thin”).
