General features : Dorsal shield oval (L/W ratio 1.1), with medial depression ( Figs. 39G–I ); muscle scars with moderately pronounced thickenings, located anterior and posterior to the postocularia; central portion of dorsal shield light blue; gnathosomal bay of a modified Y-shape (gradually narrowing in posterior half, intermediate between typically Y- or V-shape); tips of Cx-I ending posterior to frontal margin; medial margin of Cx-IV reduced to a median angle; Cx-III and -IV with numerous longitudinal striae. Palp comparatively short and stocky ( Fig. 20D ): P-1 without a dorsal seta; P-2 inflated with convexly bowed dorsal margin; P-3 proximally as high as long; P-4 equally narrowing from base to tip. Legs: I-L ( Fig. 20E ) with I-L-6 L/H ratio 2.5, ventral margin strongly protruding; IV-L: Fig. 20F . Discussion : The combination of a comparatively short and stocky palp with P-1 lacking dorsal seta and P-3 proximally as high as long, and Cx-III/IV with numerous longitudinal striae separates D. ferruginea from all other members of the genus. Distribution : Cameroon (K. Viets 1914), Liberia (Cook 1966), Zimbabwe (K.O.Viets 1970), Côte d’Ivoire (first record), Ghana (first record).
