Acanthogonatus birabeni is a mygalomorph spider of Argentina, named after Max Birabén, an Argentinian arachnologist.[1] It differs from others in the patagonicus group by its smaller size and (except for A. fuegianus) by the less developed bulb keels.
Description
- Male: total length 7.9 millimetres (0.31 in); cephalothorax length 3.27 millimetres (0.129 in), width 2.62 millimetres (0.103 in); cephalic region length 2 millimetres (0.079 in), width 1.65 millimetres (0.065 in); medial ocular quadrangle length 0.35 millimetres (0.014 in), width 0.69 millimetres (0.027 in); labium length 0.25 millimetres (0.0098 in), width 0.61 millimetres (0.024 in);sternum length 1.87 millimetres (0.074 in), width 1.46 millimetres (0.057 in). Its labium possesses no cuspules. A serrula is apparently present as a small patch of denticles. Its posterior sternal sigilla is small, shallow and marginal; its sternum weakly rebordered. Chelicerae: rastellum is formed by long, thin, stiff setae. Cheliceral tumescence is present. Leg I: tibia long and cylindrical, with an apical prolateral spur typical for this genus; metatarsus evenly curved downward in its basal third, the remainder being straight. The entire spider is a light yellow colour, with a dorsal abdominal pattern similar to that in A. patagonicus.[1]
