(Figs 27–36)

Material examined. Holotype, 1♂, China, Yunnan prov., Wenshan City, Maguan County, Diba Village, 23°7′30″N, 104°22′56″E, 1280 m, 21.VII.2015, Chunfa Chen (CQNU); paratype, 1♂, same label as holotype (CQNU).

Description. Male (Fig. 27). Body length 6.77–6.80 mm. Body black, following parts yellow: clypeus (Fig. 28), mandible, a thin and short band along lower inner eye orbit, inter-antennal spot, ventral side of scape, an elongated band on temple, an anterior interrupted transverse band on pronotum, small spot on mesepisternum, spots on outside of tegula anteriorly and posteriorly (Fig. 27), tiny spot on metanotum, apical bands of terga I–II and sternum II, an small apical spot on tergum III mesally, spot on mid coxa ventrally, and apical markings on outer sides of fore and mid femora and tibiae; tarsi brown to dark brown; wings lightly infuscate. Body with dense white setae, setae on propodeum relatively longer than those of other pars.

Head. Clypeus 1.16× as wide as long in frontal view, with dense punctures, apex deeply emarginate, with two lateral sharp teeth, emargination width about 1/4 of clypeal width (Fig. 28); mandible normal, third tooth of mandible without one deep incision; terminal antennal segment hooked and bent backward to the base of segment XI (Fig. 30); frons, vertex and temple with reticulate punctures, punctures on frons relatively denser than those on other parts of head (Fig. 29).

Mesosoma. Mesosoma with coarse punctures, punctures similar to or somewhat coarser than those on head; pronotal humeral angle blunt, dorsal face with distinctly reticulate punctures (Fig. 29); setae at upper part of mesonotum not brush-like in lateral view; mesopleuron with reticulate punctures (Fig. 31); scutellum flat, rectangle and with coarse punctures, punctures at base slightly sparser; metanotum coarsely punctate, distinctly coarser than scutellum, slightly concave mesally; dorsal surface of propodeum with honeycomb punctures, upper part of lateral face with shallow honeycomb punctures and other part coriaceous (Fig. 31); posterior face of propodeum with densely minute striae and median longitudinal carina (Fig. 32); ventral side of fore trochanter and femur with short and dense setae.

Metasoma. Tergum I (Fig. 33) much wider than long, 1.50× as wide as long in dorsal view, distinctly with coarse, large and dense punctures, gradually smaller and sparser from base to apex; tergum II coarsely punctate, punctures a little sparser than those of tergum I, apex with a row of deeper punctures forming a transverse groove, and without a bent apical lamella behind groove (Fig. 33); sternum II (Fig. 34) convex basally, with coarse punctures, punctures basally sparser than those at apex; punctures at visible part of metasomal segment III denser than those of segment II; genitalia as in figure 35: apex of volsella long, narrow and strongly sharp, penis valve as in figure 36: ventral lobe of penile valve slightly erect and basal apodeme curved from base to apex and with a small bulge near the base, basal plate of penile valve claviform, gradually narrowed at apex.

Female. Unknown.

Distribution. China (Yunnan).

Remarks. This species is allied to A. mandschuricus Blüthgen, 1953, in body with similar yellow markings, clypeus densely punctate and clypeal apex deeply emarginate. It can be distinguished from A. mandschuricus and all the other members of Allodynerus by the following character combination: mesopleuron with denser punctures (Fig. 31) (relatively sparser in Fig. 55 of A. mandschuricus), punctures of metasomal segment I and II coarser than those of the related species (Figs 33–34, 59–60), and apex of volsella long, narrow and very sharp (Fig. 35) (apex of volsella short, wide and at most pointed in Fig. 57 of A. mandschuricus).

Etymology. The specific name asperipunctarus is derived from two Latin words: asper (=coarse) and punctara (=punctures), referring to body with coarse punctures.
