Figures 822–837

Opopaea ambigua Simon, 1893b: 302 (male lectotype, here designated, from Galle , Sri Lanka, in MNHN; examined).

NOTE: Simon described both sexes of this species, but the female currently with the male here selected as the lectotype is clearly not conspecific with that male. It has a higher posterior carapace margin than does the male, anterolateral projections on the pedicel that are lacking in the male, and a deeply Wshaped anterior scutal ridge on the abdomen. We suspect that, unlike the male, the female does actually belong to Opopaea .

DIAGNOSIS: Males can easily be recognized by the distally expanded, blunt-tipped palpal bulb (figs. 830–837).

MALE (PBI_OON 556, figs. 822–837): Total length 1.17. Coloration uncertain (lectotype badly faded). Carapace with traces of dark brown egg-shaped patches behind eyes; pars cephalica slightly elevated in lateral view; posterolateral edge without obvious pits, posterior declivity without distinct shoulders, top margin apparently without enlarged setae or enlarged setal bases, posterior margin rounded, low, without apparent darkenings. Sternum without distinct pits. Scuto-pedicel region with scarcely detectable, straight scutal ridge, without apparent tubercles. Palpal bulb short, distally thickened, with blunt tip.

FEMALE: Unknown.

MATERIAL EXAMINED: Only the male lectotype (MNHN AR14180, PBI_OON 556).

DISTRIBUTION: Sri Lanka.
