General features —Dorsal shield with two pairs of anterior platelets, shoulder platelets a little shorter than frontal platelets ( Fig. 16B ); Cxgl-4 subapical, only slightly posterior of Cx-I tips; posterior suture lines of Cx-IV extending posteriorly far beyond posterior margin of genital field; excretory pore and Vgl-2 posterior to the line of primary sclerotization, excretory pore posterior to Vgl-2; gnathosoma relatively long and narrow ( Fig. 16C ), located at the end of an extrusible membranous tube. Palp segments short, ventral margin of P- 2 and P-3 without ventral tubercles ( Fig. 16D ). Measurements. Idiosoma (ventral view: Fig. 16A ) L 722, W 455; dorsal shield L 525, W 394, L/W ratio 1.33; dorsal plate L 488; shoulder platelets L 123, W 53–55, L/W ratio 2.26–2.32; frontal platelets L 134, W 47, L/W ratio 2.9; shoulder/frontal platelets L ratio 0.92. Gnathosomal bay L 56, Cx-I total L 284, Cx-I mL 228, Cx-II+III mL 34; ratio Cx-I L/Cx-II+III mL 8.35; Cx-I mL/Cx-II+III mL 6.7. Genital field L/W 142/138, ratio 1.03; distance genital field-excretory pore 203, genital field-caudal idiosoma margin 258. Gnathosoma vL 269; chelicera total L 248; palp total L 157, dL/H, dL/H ratio: P-1, 21/25, 0.85; P-2, 49/35, 1.4; P-3, 33/33, 1.0; P-4, 38/23, 1.65; P-5, 16/ 11–12, 1.4; P-2/P-4 ratio 1.29; dL of I-L: 51, 70, 79, 101, 102, 104; I-L-6 H 40, dL/H I-L-6 ratio 2.6. Remarks . In the general characters, the female specimen of this study agrees well with the description of Cook (1966) . The only differences are found in slightly larger dimensions of idiosoma and palps of the specimen from Ghana . Distribution. Liberia ( Cook 1966 ); Ghana (first record).
