( Figs. 6 A–H, 7C, 8C, 10C–D, 12C, 13) Diagnosis. MALE. Mandible robust, apically bidentate, basally beneath with rounded lobe. Clypeus anteriorly with median broad rectangle projection. Prementum with two strong longitudinal lamellate carinae. First metasomal tergum 1.6 × as long as broad. Sternum 2 without distinct lateral felt lines, at most with few microsetae. Length of cuspis about two-thirds of length of gonostylus, cuspis mesally with strong, long, dark fuscous setae. Hind coxa mesally with acute tubercle. FEMALE unknown. FIGURE 8 . Clypeus of males. A.

MALE. Body length 11.2–11.8 mm . Head black, mandible brown. Mesosoma ferruginous, except tegula dark fuscous. Legs black, except trochanters dark ferruginous, spurs black. Metasoma black, segment 1 basally ferruginous. Wings subhyaline, apical half fuscous, marginal cell darker. Frons and vertex with sparse erect fuscous setae. Gena with sparse, erect, white setae. Mandible basally with sparse, erect, pale setae, mixed with few long fuscous ones. Scape, pronotum, scutellum and propodeum posteriorly with sparse erect long white setae. Mesonotum with sparse suberect black setae. Pronotum laterally, mesopleuron and propodeum laterally with sparse recumbent white pubescence. Metasomal tergum 1 and anterior part of tergum 2 with sparse, long, erect, white setae, black ones on disc of tergum 2. Tergum 2 posteriorly and segment 3 with dense, white setae. Felt lines on tergum 2 fuscous. Segments 4–6 with dense, erect, long, black setae. Sternum 2 with sparse, erect, black setae mixed with recumbent whitish ones. Relation of head width and mesosoma width 34:40. Mandible robust, apically bidentate, basally beneath with rounded lobe. Clypeus medially concave, anteriorly with median broad rectangle projection, densely punctate, irregularly rugose, except basal median area glabrous, shiny. Prementum with two strong longitudinal lamellate carinae. Scape not carinate beneath. Ocellar area raised, relation of POL:OD:OOL 8:5:16. Frons and vertex irregularly punctate-reticulate. Gena with dense, more or less confluent punctures, mixed with fine, shallow ones. Pronotum, mesonotum and scutellum with dense, more or less confluent punctures. Pronotum laterally with fine sparse shallow punctures, except posterior portion glabrous. Mesopleuron with fine, dense, confluent punctures, mixed with sparse, separate ones. Metapleuron glabrous, shiny. Mesosternum midway to anterior margin mesally with paired high, apically acuminate lamellae. Propodeum coarsely reticulate. Length of marginal cell of fore wing 1.5 × length of first submarginal cell; second submarginal cell pentagonal, apically blunt. FIGURE 9. Genitalia of males. A, B.

Hind coxa mesally with acute tubercle. Legs with subappressed, short, fuscous setae, except femora with white long setae more than 2 × maximum width of femur. Tibio-tarsal relation of hind leg 42:30:14:10:7:7. First metasomal tergum 1.6 × as long as broad. Sternum 1 with median, strong, longitudinal carina, weakly bifurcate posterad. Sternum 2 without distinct lateral felt lines, at most with few microsetae. Hypopygium longitudinally broadly concave, laterally strongly carinate. Length of cuspis about two-thirds length of gonostylus, cuspis mesally with strong, long, dark fuscous setae. Tergum 1 with deep, separate punctures. Segment 2 with fine, sparse, separate punctures. Segment 3–6 with fine, dense, slightly confluent punctures. Tergum 7 mostly glabrous. FIGURE 10. Genitalia of males. A, B. Hemutilla . hoozana (Zavattari) , China, Zhejiang. A. Dorsal view, B.

The male of this new species differs from other species of Hemutilla by having hind coxa mesally with acute tubercle (without tubercle in other species) and the mandible apically bidentate (tridentate in other species). Etymology. The specific name is a Latin adjective meaning “tuberous" with reference to the tubercle of the hind coxa.
