Bioacoustics of Ninetis toliara

Male ( holotype ). Total length 1.0, carapace width 0.50. Leg 1: 2.97 (0.83 + 0.20 + 0.77 + 0.77 + 0.40), tibia 2: 0.63, tibia 3: 0.28, tibia 4: 0.77. Tibia 1 L/d: 15. Habitus as in N. subtilissima (cf. fig. 1 in Huber and van Harten 2001 ); entire spider pale ochre-yellow, abdomen rather ochre-grey. Ocular area not elevated, not separated from carapace; no thoracic furrow; distance PME–PME 30 Μm; diameter PME 40 Μm; distance PME–ALE 15 Μm; distance AME–AME 10 Μm, diameter AME 25 Μm. Sternum wider than long (0.36/0.32), without frontal humps. Clypeus unmodified; chelicerae with pair of distinctive frontal apophyses ( Figs. 17 , 21 ), with very fine stridulatory ridges ( Fig. 23 ). Palps as in Figs. 18, 19 ; proximal segments simple, widened but otherwise unmodified; cymbium with short and simple pointed procursus and small sclerotized prolateral projection; bulb with slender ventral projection with a tiny hook at the tip and more complex dorsal projection, partly membranous ( Fig. 22 ), probably containing the sperm duct (or situated beside the opening of the sperm duct?). Palpal tarsal organ capsulate, very small, with small orifice ( Fig. 26 ). Legs without spines and curved hairs, few vertical hairs; retrolateral trichobothrium of tibia 1 at 60%, prolateral trichobothrium not seen on any leg; tarsus 1 with about 5 very indistinct pseudosegments. Gonopore with four epiandrous spigots, arranged in two pairs ( Fig. 24 ). Variation. Tibia 1 in other male: 0.77 (missing in others). Female. In general similar to male. Tibia 1, female from type locality: 0.53; females from other localities (N=5): 0.73–0.83. Epigynum large relative to abdomen, external shape similar to N. minuta , but with a median pocket ( Figs. 25, 27 ). Pore plates not seen ( Fig. 20 ).
