Structure. Head 1.39× as wide as long in dorsal view; lateral margins strongly convergent behind eye; posterior margin truncate; vertex rounded posteriorly in lateral view; GOI = 1.30; vertex with medial longitudinal carina reaching upper frons; 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 1.04× eye height; eye height 2.47× malar distance; vertex width 1.03× pronotal width; clypeus medially elevated but not forming tubercle, with subventral transverse ridge; anterior margin of transverse ridge medially shallowly emarginate. Mandible slender tridentate, dorsal subapcial 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 1.17× its width and 1.4× 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; ratio between head width: humeral width:pronotal width:mesonotal width:propodeal width:metasomal width = 100:80:86:79:80:116; dorsal thoracic length 0.90× pronotal width; thoracic dorsum posteriorly sloping in lateral view; anterior margin of dorsum of pronotum nearly straight, with a pair of very weak rounded sublateral tubercles; 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 narrowly depressed; 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 slightly convergent anteriorly, weakly carinate on posterior half.

Type material. 1♀. Holotype ♀: Malaysia: NEGERI SEMBILAN: Pasoh Forest Reserve, 1.IV.1993, K. Konishi leg. [FRIM].
Distribution. Malaysia: Negeri Sembilan.
Etymology. The specific name auricoma, meaning “golden-haired”, is a Latin singular feminine adjective in the nominative case and refers to the orange-golden setae on the vertex and thoracic dorsum of this new species.
Remarks. This new species is similar to A. borkenti and A. takensis by having the mandible tapering to apex, but differs by having the frons and vertex with large confluent punctures (dense but separated in A. takensis), the vertex with medial carina (lacking in A. takensis), the clypeus medially elevated but lacking tubercle (with medial tubercle in A. borkenti), the metasoma with bluish metallic luster (metasomal integument black in A. borkenti and A. takensis), the S1 black (more or less reddish in A. borkenti and A. takensis), the T2 length 0.88× its width (subequal in A. borkenti), the T2 disc depressed medially (flattened in A. borkenti and A. takensis), the T2 spot small elongate (medium-sized in A. borkenti; large ovate in A. takensis), the pygidial plate finely longitudinally rugose (coarsely rugose in A. takensis), and the lateral margins of the pygidial plate carinate on the posterior half (carinate throughout in A. borkenti and A. takensis). This species was collected from a primary lowland forest during a field survey by Kazuhiko Konishi, probably by sweeping bushes (K. Konishi personal communication), as a part of Japan-Malaysia joint research project. The collecting site was described by Maetô et al. (1999).
