Simonoonops orghidani: Harvey, 2002: 456 .

DIAGNOSIS: Males can easily be recognized by the subdistal, diamond-shaped expansion on the darkened conductor (fig. 69), females by the shape of the genital atrium (figs. 42, 74), which has a pair of lateral wings that are separated from the central part of the atrium by oblique slits (figs. 75, 76).

MALE (PBI_OON 2597, figs. 1–30, 61–70): Total length 1.98. Posterior half of pars cephalica with pair of elongate, oval, paramedian light areas, surface of anterior portion reticulate, posterior portion smooth. Chilum small, triangular. Endites with both processes long, narrow, ventral process longer than dorsal process. Anterior femora darkened. Leg spination: femora: I p0-0-2, r0-1-1, II p0-0-1; tibiae: I v4-4-2, II v4-4-1p; metatarsi I, II v2-2- 1p. Embolus twisted around darkened conductor, conductor with diamond-shaped expansion at about half its length.

FEMALE (PBI_OON 2597, figs. 31–60, 71–76): Total length 2.25. Leg spination: femora: I p0-0-2, r0-1-2, II p0-0-2, r1-1-0; tibiae I, II v4-4-2; metatarsi: I v2-2-2, II v2-2- 1p. Atrium wide, semicircular, posterior portion heavily sclerotized, anterior portion mostly filled with rectangular sclerotization; anterior genitalic process long, narrow; posterior margin of transverse bar connecting genitalic apodemes invaginated at midline.

DISTRIBUTION: Coastal Venezuela and Trinidad.

SYNONYMY: Dumitrescu and Georgescu (1987) did not even cite Chickering’s (1968) paper on Dysderina ; had they consulted it, they might have detected that their Venezuelan species had already been described, from Trinidad, by Chickering.
