(Figs 4 A–H, 7B, 8B, 9A–B, 13)
Diagnosis. MALE. Mandible robust, apically tridentate, basally strongly widened beneath. Lateral section of clypeus granulate, not concave. Prementum with weak median carina and stronger lateral one, which combined anterad. First metasomal tergum 1.6 × as long as broad. Volsellar cuspis mesally with strong, long, yellow setae. FEMALE unknown.
Description. MALE. Body length 12.5–13.0 mm. Head and metasoma black, mandible infuscated. Mesosoma ferruginous-red. Legs black, except fore coxa brown, spurs black. Wings infuscated, discoidal cell hyaline, wing veins dark brown. Front and vertex with dense, erect, fuscous setae. Gena with sparse, erect, yellow setae. Mandible basally with sparse, erect, long, yellow setae. Scape with sparse, erect, yellow setae. Pronotum, scutellum and propodeum posteriorly with dense, erect, long, yellow setae. Pronotum laterally with sparse, recumbent, yellow pubescence; mesopleuron and propodeum laterally with sparse, suberect, yellow setae; other parts of mesosoma with dense, subappressed, fuscous setae. Terga 1 and 2 and sternum 1with sparse, erect, yellow setae; segments 2 and 3 posteriorly with fascia of yellow setae, sparser on sterna. Segments 4–6 with dense, erect, long, black setae.
Relation of head width and mesosoma width 24:29. Mandible robust, apically tridentate, basally strongly widened beneath. Clypeus medially concave, anteriorly with broad, almost quadrangular median projection, densely punctate; lateral section granulate, not concave; basal median area glabrous, shiny, with longitudinal strong carina. Prementum with weak median carina and stronger lateral one, which combined anterad. Scape not carinate beneath. Relation of POL:OD:OOL 8:4:19. Frons and vertex with dense, more or less confluent punctures. Gena with finer, dense, separate punctures.
Pronotum with coarse, irregular punctures. Mesonotum with dense, confluent punctures, finer on scutellum. Mesopleuron with fine, sparse, separate punctures anterad, coarser and confluent posterad. Metapleuron glabrous and shiny. Mesosternum midway to anterior margin mesally with paired high, apically acuminate lamellae Propodeum dorsally coarsely, strongly reticulate, laterally slightly irregularly reticulo-punctate.
Length of marginal cell of fore wing 1.7 × length of first submarginal cell.
Legs with long dense, erect, yellow setae. Tibio-tarsal relation of hind leg 41:29:15:9:7:7.
First metasomal tergum 1.6 × as long as broad; sternum 1 with median, longitudinal carina. Sternum 2 with well developed lateral felt line which longer than distance between line and posterior border of sternum. Hypopygium slightly longitudinally concave, laterally not carinate, punctate to smooth. Volsellar cuspis mesally with strong, long, yellow setae. Metasomal tergum 1 basally slightly longitudinally rugose. Segment 2 with coarse, more or less confluent punctures, finer and denser laterad and posterad. Segments 3–6 with fine, dense punctures. Tergum 7 glabrous on apical half and densely punctate on other part.
Material examined. Holotype, ♂, CHINA, Zhejiang, Fengyang Mountain, 25.VII.2007, Liu Jingxian, No. 201310904 (ZJUH). Paratypes. 2 ♂♂ with the same data as holotype, No. 201310905, 201310906 (ZJUH).
Distribution. China (Zhejiang).
Remarks. The male of this new species is similar to that of Hemutilla hoozana (Zavattari), but differs by having the mandible basally strongly widened beneath, acute (slightly rounded in H. hoozana); the lateral section of the clypeus not concave, granulate (concave, coarsely punctate in H. hoozana); the volsellar cuspis mesally with strong, long setae (with much shorter setae in H. hoozana).
Etymology. The specific name is a Latin adjective meaning "granulose", with reference to the sculpture of the lateral section of the clypeus.
