Diagnosis.

Males are recognized by the yellow palp and the very short palpal patella ( Fig. 22 A–C ), females are recognized by the dark, ring-shaped spot on anterior edge of epigastric furrow and the long, fork-like arms of the paddle-like sclerite ( Fig. 23C, D ).

Description.

Male. Yellow-brownish. Habitus as in Fig. 4A, C, E . Body length 1.33. Carapace ( Fig. 4B ): oval in dorsal view; sides with longitudinal streaks; dorsal area smooth, with some setae at lateral edges. Eyes: ALE largest, PLE smallest; posterior eye row straight viewed from above, procurved from front; ALE separated by less than their radius, ALE-PLE separated by less than ALE radius, PME touching throughout most of their length, PLE-PME separated by less than PME radius. Clypeus height about 0.6 times ALE diameter ( Fig. 4G ). Sternum ( Fig. 4F ) longer than wide, uniform, fused to carapace; surface finely reticulate; radial furrows present between coxae, with rows of small pits. Anterior end of endites with a small, sharply pointed projection. Legs light yellow. Abdomen: booklung covers small, ovoid, without setae. Pedicel tube short, ribbed, with small, dorsolateral, triangular extensions, scuto-pedicel region lower than diameter of pedicel, with nearly straight scutal ridges and anterior scutal ridge ( Fig. 4H ). Palp ( Figs 5 , 22 A–C ): yellow; femur slightly shorter than the patella and inserted almost basally to patella; patella very short; cymbiobulbus longer than the patella, tip of the cymbiobulbus acute.

Female. As in male except as noted. Habitus as in Fig. 6A, C, E . Body length 1.60. Endites without projections. Copulatory organ ( Figs 6H , 23C, D ): in the middle of the epigastric furrow there is a dark, ring-shaped spot; there is a paddle-like sclerite (pls) dorsally, with long, fork-like arms; nail-like process (nlp) well separated.
