Yellowish-brown, more elongated, 2.35 × as long as wide; body 1.85–1.90 mm long and about 0.60 mm wide. HEAD. Elongate, 2.00–2.10 × as long as wide, about 1.8× as long as pronotum. ANTENNA. Trimerous, 0.70–0.75 mm long, terminal antennomere slightly curved in distal portion. PRONOTUM. Transverse, 1.80–1.85 × as wide as long. METAVENTRITE. With large, triangular median impression, posterior metaventral process short, wide with straight margin. ELYTRA. 1.60–1.70 × as wide as long, 1.50–1.60× 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 cutout between two, short teeth. ABDOMEN. 1.85–1.90 × as long as elytra; composite tergite in posterior portion with pair of long, triangular, closely separated projections with rounded apex, which are clearly exceeding posterior margin of abdomen. MESOTIBIA. With obtuse, short median tooth; last mesotarsomere simple. AEDEAGUS (Fig. 4A–B). Elongate, 2.67 × as long as wide; basal bulb and distal lobe well-separated, ratio length of basal bulb/ length of distal lobe 2.40; endophallus lacking sclerites; dorsal diaphragm elliptical. Sexual dimorphism As for the genus. Distribution Madagascar (Antongila Bay). Remarks Apoderiger torticornis is related to A. banari sp. nov. and A. grandis sp. nov. sharing with both species a pair of long, triangular, short distant projections on the posterior portion of the composite tergite. It is separated from A. banari by having a pair of triangular, short distant projections longer, exceeding posterior margin of composite tergite (shorter, not exceeding posterior margin in A. banari) and having posterior metaventral process wide and short (subtriangular and long in A. banari). From A. grandis it is readily separated by body smaller than 2 mm (2.2 mm in A. grandis) and having elytra lacking discal and sutural striae which are well-defined in A. grandis. Host ant Paratrechina amblyops rubescens (Forel, 1892).
