Synonyms

Hunting singly during daytime and nesting under stones in arid coastal areas on Malta (Schembri & Collingwood 1981; Boer, 2013).

Identification

A member of the A. testaceopilosa group. By the absence of propodeal spines or teeth, the workers cannot be confused with other species. Moreover, the setae are fine instead of bristle-like, as in most species. Gynes and males unknown. (Boer 2013)

Description

Worker

Boer (2013) - Lateral sides of mesosoma with weak longitudinal rugulae, on the propodeal dorsum absent or rugulose. Head longitudinally rugulose with some cross-connections. Terminal side of propodeum, opposite of petiole rugulose and punctate. Petiolar nodes punctate. Dorsal side of postpetiole with longitudinal costulae. Microstriae on dorsal side of gaster dense, less pronounced than in other species. Dorsal side of postpetiole matt. Pronotum matt glossy. Dorsal side of gaster matt satin. Terminal side of propodeum, opposite of the petiole matt glossy. Antennal club 4-segmented. Propodeal spines absent. Terminal side of propodeum oblong, without any spine, generally slightly dentate. All hairs not bristle-like as in most species. The fine hairs of the underside of the head and anterior side of the first coxae have the same shape as those of the mesosoma.
