Bioacoustics of Nyikoa limbe

Male ( holotype ). Total length 1.7, carapace width 0.60. Leg 1: 14.0 (3.4 + 0.3 + 3.6 + 5.4 + 1.3), tibia 2: 2.2, tibia 3: 1.3, tibia 4: 2.4. Tibia 1 length/diameter (L/d): 50. Habitus as in Figs. 2, 3 ; coloration mostly pale ochre-yellow, abdomen pale ochre-gray; distance PME–PME 175 µm; diameter PME 70 µm; distance PME– ALE 15 µm; AME missing. Sternum wider than long (0.44/0.38), unmodified. Clypeus unmodified; chelicerae with pair of simple frontal apophyses ( Figs. 15 , 24 ), without stridulatory ridges. Palps as in Figs. 13, 14 ; coxa unmodified, trochanter simple, without apophysis, femur, patella and tibia widened but otherwise unmodified; procursus distinctive, highly complex ( Figs. 18–21 ), bulb with bifid projection, one part membranous (embolus?), other part thin blade-like; palpal tarsal organ capsulate ( Fig. 22 ). Legs without spines and curved hairs, few vertical hairs; retrolateral trichobothrium of tibia 1 at 12%, prolateral trichobothrium apparently absent on tibia 1, present on other legs; tarsus 1 with>10 pseudosegments, but only distally a few visible in dissecting microscope; tarsus 4 with complex comb-hairs ventrally ( Fig. 23 ). Male gonopore without epiandrous spigots ( Fig. 25 ). ALS with one widened, one pointed, and five cylindrically shaped spigots ( Fig. 27 ). Variation . Tibia 1 in other males: Cameroon ( type locality, N=9): 3.4–3.8 (mean: 3.54), Ghana (N=20): 3.0–3.7 (mean: 3.33), Congo DR (N=20): 3.2–3.7 (mean: 3.45). No variation seen in genitalia and chelicerae. Female. In general similar to male. Tibia 1: Cameroon (N=6): 3.2–3.4 (mean: 3.27), Ghana (N=22): 2.9– 3.3 (mean: 3.08), Congo DR (N=20): 3.0–3.4 (mean: 3.21). Epigynum very inconspicuous from outside, barely distinguishable from surrounding cuticle but somewhat protruding, with pair of pockets close together ( Fig. 29 ); with round pore plates and complex ‘valve’ separating uterus externus from uterus internus ( Figs. 17 , 31 ).
