Holotype:male, NAMIBIA, Kububfara, 12 kmS of Aus, 26°44′S: 16°17′E, 1800 ma.s.l., 12–17 November 1984, leg. C. Griswold NMSA 26464). Paratype: NAMIBIA, Ai Ais, 27°55′S: 17°29′E, 1 male, 19 August 1981, leg. P. Selden( NHM).
Diagnosis.The male pedipalp of this species may be distinguished from those in the other African members of the genus—except E. leipoldti Peckham & Peckham, 1903—by the large spirally coiled embolus placed parallel to the long axis of palp. It differs from E. leipoldtiin having a clearly longer embolus with the tip bent onto the dorsal surface of the cymbium and by the presence of a ventral process on the tibia.
Etymology.This species is dedicated to Charles E. Griswold, eminent arachnologist, who collected the holotype.
Description.Measurements. Cephalothorax: length 1.6, width 1.0, height 0.7. Abdomen: length 1.4, width 1.1. Eye field: length 0.8, anterior width 1.0, posterior width 0.9. FIGURES 47–54. Euophrys gracilis sp. nov.47 male holotype, dorsal view; 48 palpal organ, ventral view; 49 palpal organ, ventrolateral view; 50 palpal organ, retrolateral view; 51, 53 epigyne; 52, 54 internal structure of epigyne. Male. General appearance as in Fig. 55. Carapace moderately high, brown with darker eye field. Anterior eyes surrounded by small fawn scales. White hairs form wide streaks along lateral margins of carapace and two short stripes on eye field anteriorly ( Fig. 56). Five long bristles on “face”: three placed below median eyes and pair above, between median and lateral eyes. Chelicerae with two promarginal teeth and single tooth on retromargin. Clypeus brown, labium, endites and sternum slightly lighter. Abdomen yellowish with median brown streak in anterior half. Dorsal surface of abdomen covered with brown and greyish hairs. Venter yellowish, book-lung covers brown. Traces of greyish patches on sides. Spinnerets light yellow. Legs light brown, only ventral surfaces of femora I tinged with black. Leg hairs light, dorsal spines of femora very long. Pedipalps brownish, clothed in dark hairs, basal segments with white hairs ( Fig. 56). Segments of pedipalps short. Palpal tibia with large process on ventral surface ( Figs 57, 58) and long retrolateral apophysis, embolus spirally coiled, placed parallel to long axis of palp, very long with end folded onto dorsum of cymbium ( Figs 57–60). Femaleunknown.
