Diagnosis.

The new species resembles A. quadraticollar Wu & Chou, 1985 in having pronotal collar nearly square, vein 1 rs-m incomplete and female clypeus with three teeth on anterior margin. It differs by the following characteristics (characters of A. quadraticollar in parentheses): frontal carina originating from each frontal lobe present, extended and enclosed into an elliptical area, including anterior ocellus (frontal carina originating from each frontal lobe present, not extended or enclosed into an elliptical area); pronotum with one median longitudinal carina (pronotum without median longitudinal carina); four propodeal posterior lateral angles evident (two propodeal posterior lateral angles evident); mid and hind femora red (only hind femora red).

Description of female.

Body length 21–23 mm. Body with bright metallic blue-green and purple luster. Mandible apically reddish brown, remainder dark brown. Antennae black. Wings hyaline, smoky brown; veins and stigma dark brown. Mid and hind femora red except for distal part; tarsi dark brown. Head and mesosoma densely covered with pubescence.

Head. Mandible sharp at apex; inner edge blade-like, without inner teeth (Fig. 1 B View Figure 1 ). Clypeus beak-like, anterior margin with three teeth (Fig. 1 B View Figure 1 ). Terminal segment of labial palpus normal. Frons with dense, fine punctures; frontal carina originating from each frontal lobe present, extended and enclosed into an elliptical area, including anterior ocellus (Fig. 1 B View Figure 1 ). Frontal line long, incomplete (Fig. 1 B View Figure 1 ). Vertex with median longitudinal groove, with dense, fine punctures (Fig. 1 C View Figure 1 ). Gena with dense, fine punctures. Ratio of EW: ID = 29: 15. Ratio of F 1: (F 2 + F 3) = 17: 21.

Mesosoma. Pronotal collar nearly square, with dense, fine punctures and one median longitudinal carina (Fig. 1 D View Figure 1 ); propleurum with dense, fine punctures, and with one transverse, narrow groove, posteriorly with several short, oblique rugae on each side (Fig. 1 E View Figure 1 ); prosternum with dense, fine punctures. Scutum with dense, fine punctures; notaulus long, extending to posterior margin, crenulate (Fig. 1 D View Figure 1 ). Mesopleuron with dense, fine punctures and sparse, large punctures (Fig. 1 F View Figure 1 ). Mesosternum with dense, fine punctures and sparse, large punctures (Fig. 1 F View Figure 1 ). Omaulus crenulate (Fig. 1 F View Figure 1 ). Sternaulus absent (Fig. 1 F View Figure 1 ). Scutellum with dense, fine punctures; anterior margin with one transverse, crenulate groove (Fig. 1 D View Figure 1 ). Metanotum with dense, fine punctures (Figs 1 D, G View Figure 1 ). 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 serrated 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; transverse rugae incomplete between two oblique, longitudinal carinae on both sides (Fig. 1 G View Figure 1 ). Posterior surface of propodeum with distinct, irregular reticulation. Upper part of lateral surface of propodeum with irregular reticulation, rest smooth, nearly not punctate (Fig. 1 F View Figure 1 ). Four propodeal posterior lateral angles evident (Fig. 1 G View Figure 1 ).

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

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

Male. Differs from female as follows: Body length 18–20 mm. Mandible short, black, with one large inner tooth (Fig. 2 B View Figure 2 ). Clypeus approximately trapezoidal, covered with dense, white long setae; anterior margin truncate, with one distinct tooth medially (Fig. 2 B View Figure 2 ). Frons with dense, large punctures, and approximately irregular reticulation (Fig. 2 B View Figure 2 ). Ratio of EW: ID = 48: 31. Ratio of F 1: (F 2 + F 3) = 15: 22. Vertex, gena, pronotal collar, prosternum, scutum, mesopleuron, mesosternum, scutellum and metanotum with dense, large punctures (Figs 2 B-F View Figure 2 ). Propleurum with more and longer oblique ruga posteriorly on each side (Fig. 2 E View Figure 2 ). Propodeal enclosure with complete transverse rugae between two oblique, longitudinal carinae on both sides (Fig. 2 G View Figure 2 ). Lateral surface of propodeum almost entirely with irregular reticulation. Hind wings with vein M + Cu diverging before crossvein cu-a (Fig. 2 H View Figure 2 ). Metasomal apex not compressed laterally (Fig. 2 A View Figure 2 ); T 1 - T 3 with dense, large punctures.

Distribution.

China (Yunnan).

Etymology.

The specific name fronticarinalis originates from the Latin stem “ front ” and “ carina ” with the ending “ alis ” meaning “ belonging to ”, refers to frons with carina originating from each frontal lobe extended and enclosed into an elliptical area, including anterior ocellus.
