( Figs. 31A–F )

Mideopsis (Djeboa) obovata Cook 1966: 240 .

Material examined: Type series: FMC, Liberia; holotype female, Congo Town area, water filled ditch, 30.vii.1958 Cook (Coll. 105); paratype male, same data as holotype.

General features: Idiosoma tapering posteriorly, obovoid in shape (L/W ratio 1.1–1.2), dorsal shield without medial depression; muscle scars with weakly pronounced thickenings, located anterior and posterior to the postocularia; colour pattern unknown; gnathosomal bay Y-shaped, narrowing in posterior half; tips of Cx-I ending posterior to frontal margin; medial margin of Cx-IV not reduced to a median angle; Cx-III and -IV with a few longitudinal striae (two or three pairs on Cx-IV) Palp ( Fig. 31D ): P-1 without a dorsal seta; P-2 with slightly concave ventral and convexly bowed dorsal margin; P-3 ventral margin slightly concave; P-4 equally narrowing from the base to distal edge. Legs: I-L ( Fig. 31E ) with I-L-6 dL/H ratio 3.2; IV-L: Fig. 31F .

Discussion: Differing from all known species of the genus in the obovate idiosoma shape.

Distribution: Liberia (Cook 1966).
