Diagnosis.

The new species resembles A. longiabdominalis Wu & Chou, 1985 in having frontal carina not extended or enclosed into an elliptical, mid and hind femora red, and fore wings with three submarginal cells. It differs by the following characteristics (characters of A. longiabdominalis in parentheses): anterior margin of clypeus with five teeth (anterior margin of clypeus with three teeth); scutum with sparse, large punctures (scutum nearly without punctures); sternaulus present, short and narrow (sternaulus absent); wings hyaline, proximal part of forewing with dark brown marking (wings hyaline, entirely smoky brown); mandible dark brown, with apex and inner edge reddish-brown (mandible entirely red).

Description of female.

Body length 22–31 mm. Body with dark metallic blue-green and purple luster. Mandible dark brown, with apex and inner edge reddish-brown. Antennae black. Wings hyaline, veins and stigma dark brown, proximal part of forewing with dark brown marking. Mid and hind femora red except for distal part; tarsi dark brown. Clypeus, prosternum, mesosternum and upper part of lateral surface of propodeum densely covered with slivery pubescence.

Head. Mandible sharp at apex; inner edge blade-like, without inner teeth (Fig. 3 B View Figure 3 ). Clypeus beak-like, anterior margin with five teeth (Fig. 3 B View Figure 3 ). Terminal segment of labial palpus setose. Frons with dense, fine punctures; frontal carina originating from each frontal lobe present, not extended or enclosed into an elliptical (Fig. 3 B View Figure 3 ). Frontal line long, complete (Fig. 3 B View Figure 3 ). Vertex and gena with sparse, large punctures and dense, fine punctures (Fig. 3 C View Figure 3 ). Ratio of EW: ID = 31: 19. Ratio of F 1: (F 2 + F 3) = 32: 37.

Mesosoma. Pronotal collar nearly rectangular, with dense, fine punctures and sparse, midsized punctures; median longitudinal groove narrow and shallow (Fig. 3 D View Figure 3 ); propleurum with dense, fine punctures and one transverse, narrow groove on each side (Fig. 3 E View Figure 3 ); prosternum with dense, fine punctures. Scutum with sparse, large punctures and dense, fine punctures; notaulus narrow and short, not extending to posterior margin, not crenulate (Fig. 3 D View Figure 3 ). Mesopleuron and mesosternum with sparse, large punctures and dense, fine punctures (Fig. 3 F View Figure 3 ). Omaulus not crenulate (Fig. 3 F View Figure 3 ). Sternaulus short, not crenulate (Fig. 3 F View Figure 3 ). Scutellum with dense, fine punctures and sparse, large punctures; anterior margin with one transverse, crenulate groove (Fig. 3 D View Figure 3 ). Metanotum with dense, fine punctures (Figs 3 D, G View Figure 3 ). Propodeal enclosure approximately trapezoid, medially with five strong, longitudinal carinae, including one median longitudinal carina, two strong, oblique, longitudinal carinae on either side, and two oblique, longitudinal carinae located further out to sides; numerous nearly parallel transverse rugae connected five carinae and edge carinae on either side, forming distinct, regular reticulation except posterior central part with irregular reticulation (Fig. 3 G View Figure 3 ). Posterior surface of propodeum with distinct, irregular reticulation. Upper part of lateral surface of propodeum with irregular reticulation, rest with sparse, large punctures and dense, fine punctures (Fig. 3 F View Figure 3 ). Four propodeal posterior lateral angles evident (Fig. 3 G View Figure 3 ).

Wings and legs. Fore wings with three submarginal cells, vein 1 rs-m complete, vein M + Cu diverging at crossvein cu-a. Hind wings with vein M + Cu diverging before crossvein cu-a (Fig. 3 H View Figure 3 ). Claws bifid (Fig. 3 I View Figure 3 ).

Metasoma. T 1 - T 2 with sparse, fine punctures; T 3 with dense, large punctures; T 4 - T 6 alutaceous. T 2 with one transverse groove near anterior margin. Metasomal apex laterally compressed.

Male. Unknown.

Distribution.

China (Guangxi, Fujian).

Etymology.

The specific name genapunctata originates from the Latin word “ gena ” and “ punctata ”, refers to the gena with sparse, large punctures.
