Rahanitriniaina lgt.”; PCPH. Description BODY. Yellowish-brown, more elongated, about 2.40–2.50 × as long as wide; body 1.70–1.80 mm long and about 0.72 mm wide. HEAD. Elongate, 2.15–2.30 × as long as wide, 1.90–2.00 × as long as pronotum. ANTENNA. Trimerous, 0.74–0.75 mm long, terminal antennomere slightly curved in distal portion. PRONOTUM. Transverse, 1.47 × as wide as long. METAVENTRITE. With large median impression, posterior metaventral process long, slender, parallel-sided with two separate setae. ELYTRA. 1.70–1.75 × as wide as long, 1.60–1.70× as long as pronotum; lacking sutural and discal striae; humeri strongly projecting; lateral margin with some stout setae; posterior elytral margin in lateral third with pair of subequal teeth. ABDOMEN. 1.60–1.80× as long as elytra; composite tergite in posterior portion with pair of small, bump-like, widely separated projections. MESOTIBIA. Simple, last tarsomere with distal, sharp lamella. AEDEAGUS (Fig. 4C–D). Elongate, 2.50 × as long as wide, distal lobe with round apex; basal bulb and distal lobe well-separated, ratio length of basal bulb / length of distal lobe 1.20; endophallus with sclerite having two differently shaped arms; dorsal diaphragm semicircular. Sexual dimorphism As for the genus. Distribution Madagascar (Anjozorobe-Andasibe massif). Remarks A. sikorai sp. nov. is related to A. spinosus sharing a pair of small, bump-like, wide-distant projections on the posterior portion of the composite tergite. It is separated from A. spinosus by larger body over 1.7 mm long (length of A. spinosus 1.4 mm) and having mesotibia lacking inner projection which is well-defined in A. spinosus. Host ant Unknown.
