Diagnosis. In A. evansi, sp. nov., both sexes also have a black head and mesosoma with reddish orange metasoma, but the females lack the contrasting silver setae on the head and mesosoma forming an obvious pattern, which is found in the males (Figs. 3 b,c,d,e). However, the pronotum of the male only has a broad integumental band of whitish yellow and lacks black setal patches, and the propodeum has only the posterior face with whitish long setae, while the remainder is black (Fig. 3 c,e). Additionally, the female has three comb spines and the last metasomal tergum has thin setae, while the aedeagus of the male is slightly longer than the parapenial lobes and has expanded apical lobes (Fig. 5).
Description. Holotype Male. Length 11.5 mm (7.5 mm – 17 mm). Coloration (Figs. 5 c,e). Integument of head, scape, mesosoma and legs black; integument of metasoma orange. Labrum and apical 2/3 of mandible reddish brown. Flagellomeres black dorsally, orange ventrally. Pronotum with broad yellowish white integumental transverse band on posterior margin, width of approximately half of length of vertical and dorsal portion of pronotum. Silver setae on head, scape, vertical face of pronotum, prosternum, mesopleura dorsal contiguous with pronotal band, Mesopleura ventrally contiguous with mesocoxae, anterior faces of pro and mesocoxae, posterior third of mesoscutum, scutellum laterally, metanotum, propodeum anterior to spiracles and in a thin band posterior to postnotum, posterior face of propodeum, legs from tibiae to tarsi, and metasomal terga and sterna. Setae on T7 denser than elsewhere on metasoma. Remainder of mesosoma covered with short, dense, decumbent black setae. Head, propodeum and venter of metasoma with sparse, erect, orangish white, erect setae. Wings hyaline, slightly infuscated apical to closed cells and in MC. Head. Head round; TFD 1.08 × FD; MID 0.63 × FD. Ocelli in oblique triangle; lateral ocelli slightly closer to each other than to compound eyes; POL 1.12 × OOL. Mandible wide, with two sharpened apical teeth, basal tooth longer. Clypeus truncate, large, anterior margin slightly sinuous with slight broad emargination; LC 0.47 × WC; clypeal projection absent medially; dorsal surface slightly convex laterally; sculpture obscured by dense setae. Maxillary beard absent. Antenna elongate; length of third and fourth segments 2.4 × their width; ratio of the first four antennal segments 4.2:1:2.9:2.9; LA3 2.1 × UID. Mesosoma. Sculpture coriaceous where not obscured by setae. Pronotum not elongated, posterior margin angulated, pronotal collar inconspicuous. Notauli absent. Postnotum with integument covered by setae. Wing long; 1m-cu meeting 2SMC at apical third; 2SMC ~2 × length of 3SMC measured on MC; 2rs-m straight. M and cu-a in hind wing interstitial on M+CuA. Front tibia spines absent on anterior margin, few on base; mid tibia spines present, thick, sharpened, abundant; hind tibia dorsal spines present, arranged in two rows; tibial brush thinning before apex, but complete. Metasoma. Sculpture coriaceous. Venter lacking dense brushes of setae. S6 with median emargination that is Ushaped bearing lateral brown spine. Subgenital plate elongate, slightly truncate apically, bearing denser, thicker brown setae along posterior margin; with median longitudinal rounded carina that is more pronounce anteriorly and becomes indistinct posteriorly. Genitalia (Fig. 5). Paramere long, bypassing aedeagus and parapenial lobes; basal third wider and laterally flattened; apical two-thirds finger-like and dorsoventrally flattened towards apex; setae long, thin, sparse found throughout apical two-thirds; ventral squama absent. Parapenial lobe split; lobe broad and thickened, becoming spatulate apically. Digitus wide, truncate, punctate; length 0.6× paramere length; apex dorsally curved. Basal hooklets absent. Aedeagus long, slender, slightly longer than parapenial lobe, apex flaring laterally.
Allotype Female. Length 14.2 mm (12.3–14.2 mm). Coloration (Figs. 3 b,d). Head, mesosoma, and legs from coxae to femora black; remainder of legs dark brown tinged with rufous; scape and pedicel dark brown; flagellomeres lighter brown, tinged with rufous; mandible with apical half rufous, basal half dark brown; metasoma orange, except extreme apex of T1 black; wing brown. Head, mesosoma, and legs covered in dense decumbent brown setae discernible from integument only at high magnification. Head and dorsum of femora with sparse erect brown setae. Metasoma covered in short, decumbent, silver setae only visible at certain angles, except T6 more densely and distinctly covered in short, dense, silver setae. T6 also with sparse, longer, erect, brown setae. Head. Head wide; TFD 1.15 × FD; MID 0.68 × FD. Ocelli in oblique triangle; lateral ocelli closer to each other than to compound eyes; POL 0.90 × OOL. Mandible wide, with two sharpened apical teeth, basal tooth longer. Clypeus with anterior slight broad emargination; LC 0.35 × WC; clypeal lacking projection medially; dorsal surface slightly convex laterally; anterior margin nitid. Maxillary beard absent. Antenna elongate; length of fourth segment 3.4 × its width; ratio of the first four antennal segments 2.8:1:6:3.4; WA3 0.20× LA3; LA3 0.91 × UID. Mesosoma. Pronotum not elongated, posterior margin angulated; pronotal collar inconspicuous. Notauli absent. Postnotum thin band not obscured by setae. Propodeum with sloping dorsal face and distinct vertical face. Wing long; 1m-cu meeting 2SMC at apical third; 2SMC 2 × length of 3SMC measured on MC; 2rs-m straight. M and cu-a in hind wing interstitial on M+CuA. Front tibia with 3 comb-spines; spines absent on anterior margin; mid tibia spines present, thick, sharpened, abundant; hind tibia with two rows of dorsal spines; tibial brush thick, complete. Metasoma. Metasoma coriaceous.
