Metasoma black; T2 length 0.88× width; T2 disc flattened medially, with anteromedial large ovate spot of golden setae; T2 punctures small confluent; T2 posterior band wide, pale golden, complete; T3 with wide uniform band of golden setae; S1 yellowish red; S2 punctures large dense; surface of pygidial plate coarsely longitudinally rugose anteriorly and granulate posteriorly; lateral margins of pygidial plate subparallel, carinate throughout. MALE. Unknown.
Description. FEMALE. Body length 5.2 mm. Color and setae. Head black with gena, prementum, and stipes brownish black; antennal rim yellowish brown; clypeus except anterior margin of transverse ridge and F2–10 dorsally dark brown; mandible basal half yellow; palpi brownish yellow; scape and pedicel orange; F1 and F2–10 ventrally brown; mesosoma yellowish red; coxae, trochanters, and femora except femoral apices orange; femoral apices, tibiae, and apical tarsomere pale brown; other tarsomeres brownish yellow; tibial spurs pale yellow; metasoma black with S1 yellowish red; S2 brownish black. Frons and vertex with sparse short recumbent golden and sparser long erect black setae; antennal scrobe with sparse long appressed pale golden setae; eye dorsal margin with long erect black setae; gena, coxae, trochanters, femora and tibiae with sparse long recumbent and sparse long erect pale golden setae; clypeus and scape with sparse long recumbent pale golden setae; mandible, posterior propodeal face, propleuron, T1, T2 around margins, T3, T6, and all sterna with sparse long erect pale golden setae; prementum, stipes and palpi with sparse extremely short erect pale golden setae; pedicel and F1 with sparse short recumbent pale golden setae; F2–10 with dense extremely short recumbent pale golden setae; thoracic dorsum with sparse short recumbent and sparser long erect black setae; lateral face of mesosoma with sparse short appressed pale golden setae; ventral half of mesopleuron with sparse short appressed and sparser long erect pale golden setae; tarsi with sparse long appressed pale golden setae; T2 disc with dense short recumbent and sparse long erect black setae; T4–5 with dense long recumbent and sparse long erect black setae; pygidial plate glabrous with thickened lateral pygidial fringe of long erect golden setae; T1 and S2–6 with posterior fringe of sparse long golden setae; T2 with large ovate (1.11× as long as wide) anteromedial spot of dense appressed golden setae reaching anterior margin of T2, and with posterior narrow band of dense appressed golden setae slightly widened medially; minimum distance between spot and band on T2 0.70× spot length; T2 with lateral golden felt line; T3 with wide uniform band of dense appressed golden setae.
Structure. Head 1.45× as wide as long in dorsal view; lateral margins strongly convergent behind eye; posterior margin truncate; vertex rounded posteriorly in lateral view; gena narrow with GOI = 2.00; vertex without medial longitudinal carina; lower frons with short medial longitudinal groove; genal carina distinct; hypostomal tooth sharp; antennal scrobe with dorsal carina reaching mandibular base; eye oval, slightly protruding from head capsule; minimum distance between eyes 1.02× eye height; eye height 2.62× malar distance; vertex width 1.04× pronotal width; clypeus medially elevated but not forming tubercle, with subventral transverse ridge; anterior margin of transverse ridge medially shallowly emarginated. Mandible slender tridentate, dorsal subapical tooth smaller than middle subapical tooth, middle subapical tooth smaller than apical tooth; ventral margin straight. Prementum with posterior rounded tubercle. Scape bending medially; F1 length 1.25× its width and F2 length; F2–9 almost same in length and width; F10 slightly longer than F9, conical and weakly depressed.
Mesosoma broadest at pronotal spiracles, with lateral margins weakly convergent posteriorly; ratio between head width:humeral width:pronotal width:mesonotal width:propodeal width:metasomal width = 100:78:88:80:81:119; dorsal thoracic length 0.82× pronotal width; thoracic dorsum evenly convex in lateral view; anterior margin of dorsum of pronotum nearly straight, without sublateral tooth or tubercle; pronotum laterally weakly projecting but not forming distinct angle at pronotal spiracle; lateral margin of mesosoma weakly crenulate; humeral angle angulate; humeral carina lamellately projecting; prescutellar scales and metanotal-propodeal suture obliterated; dorsal and lateral propodeal faces not separated by carina; posterior propodeal face without medial longitudinal carina.
Metacoxa with weak complete inner longitudinal carina; meso- and metatibiae with a pair of longitudinal rows of five spines on outer face; protarsus with external comb of long spines.
T1 without distinct dorsum; T2 disc medially flattened; dorsal T2 length 0.88× T2 width; S1 with straight medial longitudinal carina; S2 with anteromedial short inconspicuous longitudinal carina; posterior margin of S6 bidentate; pygidial plate slightly convex, elongate; lateral margins of pygidial plate subparallel, weakly carinate throughout but not enclosed.
Frons, vertex, T2 laterally, and S2 with large dense punctures; gena and thoracic dorsum with large confluent punctures; clypeus, pedicel, F1, pronotal collar, propleuron, coxae, trochanters, femora, tibiae, and tarsi with minute sparse punctures; scape, T1, S1, and S3–6 with small sparse punctures; F2–10, lateral face of pronotum, metapleuron, and lateral propodeal face with minute dense punctures; posterior propodeal face reticulate; mesopleuron with minute dense punctures, with few large punctures on ventral half; T2 disc with small confluent punctures; T3–6 with small dense punctures; pygidial plate coarsely longitudinally rugose on anterior 2/3, granulate posteriorly.
Type material. 1♀. Holotype ♀: Thailand: TAK: Sam Nagao, Bhumibol Dam, 6–8.XI.1979, Zool. Mus. Copenhagen Exped. [ZMUC].
Distribution. Thailand: Tak.
Etymology. The specific name takensis is a Latin singular feminine adjective in the nominative case and derived from Tak, the Thai province where the type locality of this new species is located.
Remarks. This new species is similar to A. auricoma sp. nov. and A. borkenti as discussed above. Given the wide distribution of A. rong sp. nov. in northern Thailand, A. takensis sp. nov. may share the overlapping geographical range with this species. These two species are potentially confusing because of the overall body color, specifically the scape orange, the legs basally yellowish red, and the T2 with a ovate setal spot. However, A. takensis differs from A. rong by having the mandible slender with two acute subapical teeth (mandible wide and apically dilated in A. rong).
