Bioacoustics of Spermophora abibae

Description Male ( holotype ) MEASUREMENTS. Total body length 2.1, carapace width 0.7. Leg 1: 4.7 + 0.3 + 4.8 + 7.9, tarsus missing, tibia 2: 2.7, tibia 3: 1.8, tibia 4: 2.7; tibia 1 L/d: 68. Distance PME-PME 135 µm, diameter PME 80 µm, distance PME-ALE 25 µm, AME absent. COLOR. Carapace pale ochre-yellow with narrow black margins and indistinct median line ( Fig. 84 ), ocular area and clypeus with dark pattern, sternum whitish ( Fig. 89 ), legs ochre-yellow, with indistinct dark rings subdistally on femora and tibiae, abdomen mostly pale gray, with distinct dark pattern dorsally and laterally, ventrally only pair of marks at booklung covers. BODY. Habitus as in Fig. 84 ; ocular area slightly elevated, each triad on low hump; carapace without median furrow (only dark line); clypeus with distinctive bifid process, about 120 µm long ( Figs 85 , 92 ); sternum wider than long (0.52/0.44), unmodified. Chelicerae as in S. dieke and S. akwamu (cf. fig. 89 in Huber & Kwapong 2013 ), with pair of weakly sclerotized processes proximally, distally without modification, without stridulatory ridges. PALPS. As in Figs 86-88 , apparently indistinguishable from S. dieke and S. akwamu ; coxa with indistinct ventral process, trochanter with long ventral and shorter retrolateral apophyses, procursus with ventral sclerotized flap, prolatero-dorsal hinged process and thin distal flagellum; bulb with hooked apophysis and long weakly sclerotized embolus. LEGS. Without spines and curved hairs, few vertical hairs; retrolateral trichobothrium on tibia 1 at 10%; prolateral trichobothrium absent on tibia 1, present on other tibiae. VARIATION. Tibia 1 in 30 other males:4.8-5.9 (mean 5.3), in one exceptional but otherwise indistinguishable male: 3.0. Female In general similar to male but sternum in most females dark brown or black ( Fig. 90 ), clypeus unmodified, carapace with small median process acting against indistinct sclerotized plate above pedicel. Tibia 1 in 30 females : 3.7-4.9 (mean 4.3). Epigynum simple rectangular plate, anteriorly with dark transversal internal structure, without pockets ( Fig. 91 ); internal genitalia as in Fig. 93 .
