Holotype, ♀ (CSCS), "[China:] Hubei, Shennongjia Nature Reserve, Banbiyan, 2600 m, 26.VI.2002, Yi-hai Zhong".

Diagnosis.

Apex of ovipositor sheath ivory, ivory part 0.8 times as long as hind basitarsus; ovipositor sheath comparatively wide (Fig. 45); ovipositor sheath 0.9 times as long as hind tibia and 0.6 times as long as hind tibia and tarsus combined; occipital carina obsolescent medio-dorsally (Fig. 43) and rather protruding ventro-posteriorly (Fig. 38); antesternal carina narrow; head, laterally mesosoma and scape black; head in anterior view slightly protruding below lower level of eyes by less than basal width of mandible and mandibular condylus near lower level of eyes (Fig. 42); in lateral viewcondylarincision of malar space close to eye (Fig. 38); clypeus with shallow triangular depression at ventral 0.8 (Fig. 42); eyes inconspicuously setose; fourth and fifth antennal segment 1.4 and 1.2 (♀) times as long as third segment, respectively (Fig. 46); apical antennal segment 1.2 times as long as third antennal segment and paler than medial segments; antenna of female yellow-brown apically; sculpture of mesoscutum and head dissimilar, matt (Fig. 40); head dorsally densely coriaceous, but mesoscutum densely rugulose and medio-posteriorly reticulate-rugose; propleuron robust and 0.8 times as long as mesoscutum in front of tegulae (Fig. 39); hind coxa finely transversely striate and rather slender; hind tibia narrow and elongate, without subbasal ivory patch and ventral border slightly convex (Fig. 41); hind basitarsus comparatively long (Fig. 41); hind tibial spurs yellow-brown; hind tarsus dark brown; apical sixth of hypopygium incised and hypopygium pale apically.

Description.

Holotype, female, body length 17.6 mm, of fore wing 9.0 mm.

Head. Vertex and frons matt and very finely densely coriaceous, moderately convex (Fig. 38) and without a depression medio-posteriorly (Fig. 43); head gradually narrowed behind eyes and U-shaped excised medio-posteriorly (Fig. 43; more distinctly so if head in plane of vertex); temple 0.7 times as long as eye in dorsal view (Fig. 43); fourth antennal segment 1.4 times as long as third segment and 0.8 times as long as second and third segments combined, fifth antennal segment 1.2 times as long as third segment (Fig. 46), third antennal segment 1.4 times as long as second segment; occipital carina narrow and non-lamelliform medio-dorsally; ocelli comparatively small, OOL 1.8 times as long as diameter of posterior ocellus; face wide (Fig. 42); minimum width of malar space 0.3 times as long as second antennal segment (Fig. 38); clypeus with shallow triangular depression up to dorsal fifth and slightly emarginate (Fig. 42); eye inconspicuously setose.

Mesosoma. Length of mesosoma twice its height; pronotal side moderately high and ventrally largely rugulose, without distinct antero-lateral tooth, but angularly protruding (Fig. 39); mesoscutum slightly protruding anteriorly; propleuron robust and 0.8 times as long as mesoscutum in front of tegulae; antesternal carina narrow and hardly lamelliform; mesoscutum densely rugulose, medio-posteriorly reticulate-rugose and matt; scutellum irregularly rugose (Fig. 40).

Wings. First discal cell elongate triangular and with vein 3-CU1 near apical third (Fig. 44).

Legs. Hind coxa finely transversely striate, rather slender and with satin sheen; length of hind femur, tibia and basitarsus 4.5, 5.6 and 6.0 times their width, respectively; middle tarsus elongate (Fig. 41), 1.2 times as long as middle tibia; middle femur subparallel-sided and much slenderer than fore femur.

Metasoma. Ovipositor sheath 0.2 times as long as body, 0.3 times as long as metasoma and 0.9 times as long as hind tibia; ivory apical part of sheath 0.8 times as long as hind basitarsus; hypopygium shallow v-shaped apically.

Colour. Black or black-brown; mandible yellow-brown; antenna apically yellow-brown, tegulae and legs more or less dark brown, but hind tibial spurs yellow-brown; pterostigma dark brown; wing membrane subhyaline.

Male. Unknown.

Distribution.

China (Hubei).

Biology.

Unknown. Collected in June in montane zone (2600 m).

Etymology.

From the specific name “assectator” and “oides” (Latin for “resembling”), because of its superficial similarity to Gasteruption assectator .
