(A) dorsal habitus; (B) front; (C) ventral view of the left palp; (D) left palp, retro lateral view. Figure 18 . Stephanopis cambridgei (A and B) females and a (C) male. Photos by Allan Lance. Diagnosis . Females of S. cambridgei are similar to those of S. rufiventris , in having an elongated body ( Fig. 18 A–C), predominant orange coloration and obovate opisthosoma. However, they can be distinguished by the prosoma being longer than wide, with two pairs of longitudinal lines (a median pair that runs from the carapace slope until the posterior eye row and a lateral one placed close to the border of the prosoma and limited to the thoracic portion), epigynal plate flattened with depressed atrium, CO hidden by the lateral folds (like a pair of lateral pockets) ( Fig. 16C ), and long, coiled and membranous copulatory ducts ( Fig. 16D ). Males are easily recognized by their set of modified (long, thin and filiform) barbs on tibiae and metatarsi I ( Fig. 17A ) and by the remarkably rounded and big palpi with a single curved RTA ( Fig. 17C and D ). Description . Female (AMS KS.10530): Cephalic area slightly elevated with a pair of whitish setae on the MOQ ( Fig. 16B ); anterior eyes arranged in a strongly recurved row and posterior ones in a straight row; PLE preceded by a pair of clavate setae. Clypeal area and chelicerae striped; prosoma and legs orange with reddish-brown stripes and sparse spots; tibiae I bear five pairs of ventral macrosetae ( Fig. 16A ). Opisthosoma obovate, with anterior border slightly concave, yellowish with median light-brown bands weakly delimited by darker ones on both sides ( Fig. 16A ). Spermathecae elongated, with glandular-heads directed laterally ( Fig. 16D ).
