(Figs 5 A–H, 7A, 8A, 9C–D, 12D, 13)
Diagnosis. MALE. Mandible robust, apically tridentate, basally beneath strongly widened. Prementum with strong median carina. First metasomal tergum 2.0 × as long as broad. Volsellar cuspis mesally with sparse, short, fuscous setae. Legs ferruginous. FEMALE unknown.
Description. MALE. Body length 9.5 mm. Head black, mandible, clypeus and scape brown. Mesosoma ferruginous, except tegula dark ferruginous. Legs ferruginous, spurs fuscous. Metasoma black, segment 1 ferruginous, except tergum 1 posterad black. Wings subhyaline, apical half fuscous, submarginal cells darker. Vertex with sparse, erect, fuscous setae, yellow ones on frons and gena. Mandible basally, scape, pronotum, scutellum, propodeum posterd, and metasomal terga 1 and 2 with sparse, erect, long, yellow setae. Mesonotum with sparse, suberect, fuscous setae. Pronotum laterally, mesopleuron and propodeum laterally with sparse, recumbent, yellow pubescence. Tegula posterad with tuft of yellow setae. Tergum 2 posteriorly, tergum 3, sterna 2 and 3 with dense, yellowish setae, mixed with black ones on segment 3. Segments 4–6 with dense, erect, long, black setae.
Relation of head width and mesosoma width 41:44. Mandible robust, apically tridentate, basally beneath strongly widened, rounded. Clypeus medially slightly concave, anteriorly with median rectangle projection; lateral section of clypeus not concave, finely rugose; basal median area glabrous, shiny. Prementum with strong median carina. Scape not carinate beneath. Frons with distinct median furrow. Relation of POL:OD:OOL 11:5:30. Frons, vertex and gena with dense, more or less confluent punctures.
Pronotum and scutellum with dense, confluent punctures, more elongate on mesonotum. Pronotum laterally irregularly rugose; mesopleuron anteriorly with fine, dense, punctures, mixed with sparser larger ones, posteriorly with larger dense punctures. Metapleuron glabrous, shiny. Mesosternum midway to anterior margin mesally with paired high, apically acuminate lamellae. Propodeum dorsally coarsely reticulate, laterally slightly irregularly reticulo-punctuate.
Length of marginal cell of fore wing 1.4 × length of first submarginal cell.
Legs with long dense, erect, pale setae. Tibio-tarsal relation of hind leg 43:31:13:11:6:6.
First metasomal tergum 2.0 × as long as broad. Sternum 1 with median, strong, longitudinal carina weakly bifurcate posterad. Sternum 2 with lateral felt line 0.5 × distance between line and posterior border of sternum. Hypopygium longitudinally broadly concave, finely punctate, laterally slightly carinate. Volsellar cuspis mesally with sparse, short, fuscous setae. Tergum 1 basally longitudinally rugose. Segment 2 with coarse punctures, mixed with fine ones. Segments 3–6 with fine, dense, separate punctures. Tergum 7 mostly glabrous, laterally finely rugose.
Material examined. Holotype, ♂, CHINA, Hunan, Bucheng, Nanshan, Mufang, 4.VIII.1985, Chen Naizhong, No. 200012099 (ZJHU).
Distribution. China (Hunan).
Remarks. The male of this new species is similar to that of Hemutilla hoozana (Zavattari), but differs by having mandible beneath basally strongly widened (slightly rounded in H. hoozana); the legs and metasomal segment 1 ferruginous-red (black in H. hoozana).
Etymology. The specific name consists of a Latin adjective meaning "ferruginous" and a Latin noun pes, meaning "leg" with reference to the ferruginous legs.
