Workers.

TL5.33-5.84, HL 1.23-1.32, HW 1.16-1.23, CI 93-98, SL 1.00-1.09, SI 82-89, ED 0.16-0.21, PW 0.65-0.70, MSL 1.54-1.72, PL 0.27-0.32, PH 0.52-0.61 (n=7) (After Leong et al., 2018).

In full-face view head longer than broad, posterior margin strongly concave. Mandibles linear, gradually broadened apically; inner margin without denticles; apical portion with three distinct teeth. Antennae 12-segmented; scapes not exceeding to posterior corners of head. Eyes moderate-size.

In lateral view mesosoma stout, dorsal outline of posterior half of pronotum and mesonotum straight. Posterolateral corners of propodeum obtusely angulate. Petiole thin, distinctly higher than long, with acute triangular tip; anterior margin straight, posterior margin distinct convex; subpetiolar process developed with subtriangular ventral margin. Dorsal margin of petiole weakly concave in anterior view.

Frons and anterior part of vertex longitudinally striate extending to posterior lobes of head, remainder of head smooth and shining. Clypeus smooth and shining. Pronotum longitudinally striate. Mesonotum and propodeum transversely striate. mesopleuron smooth and shining. Petiolar node smooth and shiny except basal area faintly striate. Gaster smooth and shining.

Dorsum of body with abundant erect to suberect hairs and abundant decumbent pubescence; scapes and tibiae with scattered subdecumbent hairs dense pubescence. Body reddish brown; antennae, legs and petiole yellowish brown.

Recognition.

The species is similar to A. ruginotus Stitz, 1925, but can be distinguished from the latter by the following characters: eyes larger with 12 ommatidia along the maximum diameter; dorsal outline of mesosoma straight.

Distribution.

Known only from the type locality - Orchid Island of Taiwan.
