Description

Male

BODY. Length: 6 mm (Fig. 10A).

HEAD. Dark, 1.2 × as wide as long (Fig. 10B). Clypeus domed, irregularly punctate, punctures separated by 0.5 puncture diameters laterally, by 0.5–2 puncture diameters medially, underlying surface smooth and shining. Process of labrum rounded rectangular, 2 × as wide as long, fore margin emarginate, surface smooth and shining. Gena equalling width of compound eye; ocelloccipital distance 1.5 × diameter of lateral ocellus. Head medially with short pale pubescence, with scatter black hairs laterally; gena, vertex, and scape with pale hairs. Antennae dark, A4–13 ventrally lightened by presence of dark orange-brown scales. A3 much shorter than A4, approximately ½ length, A4–13 elongate, rectangular, 2 × as long as broad (Fig. 10C).

MESOSOMA. Scutum laterally and anteriorly microreticulate, dull, sculpture becoming weaker medially, here smooth and shining; surface punctate, punctures separated by 0.5–1 puncture diameters, obscure laterally, becoming more visible medially (Fig. 10D). Scutellum with weaker sculpture, predominantly smooth and shining, punctation equal. Pronotum rounded. Mesepisternum microreticulate, overlain by network of moderately raised irregular rugosity, dull. Propodeum strong microreticulation overlain by dense network of raised rugosity, propodeal triangle broad, laterally defined by raised carinae, internal surface with raised rugosity, not strongly differentiated from sculpture of dorsolateral parts of propodeum. Mesosoma covered with pale, weakly plumose hairs. Legs dark, apical tarsal segments lightened brownish, pubescence whitish. Hind tarsal claws with strong inner tooth. Wings hyaline, stigma orange-brown, venation dark orange, nervulus strongly antefurcal.

METASOMA. Tergal discs dark, apical rims moderately lightened hyaline-brown yellow (Fig. 10E). Tergal discs and margins finely and densely punctate, punctures separated on average by 1 puncture diameter, underlying surface finely shagreened, shining. Declivity of T1 with erect white hairs, T2–4 with weak apical hairbands of moderately long white hairs, condition degraded, widely separated on T2–3, nominally complete on T4. T6–7 with light brown hairs overlying pseudopygidial plate of T7. S8 columnar, apex slightly broadened, rounded; ventral surface with lateral fan of brown hairs. Genital capsule somewhat elongate, gonocoxae weakly produced into rounded teeth apically, gonostyli basally narrow, broadening apically, spatulate, with inner margin raised (Fig. 10F). Penis valves parallel sided, occupying ½ space between gonostyli.

Remarks

Newly recorded from India, including the first record of the male, which is described here. Tadauchi & Matsumura (2007) recorded the species from January and February only, and our late capture dates indicate that the species may be bivoltine, or at least sporadic in emergence. Diagnosis against A. tungnatha is provided above, and the male sex is described here.

Distribution

India * (Punjab, Uttarakhand) and Nepal (Tadauchi & Matsumura 2007).
