Figures 148–218

TYPES: Male holotype, female allotype, and four male paratypes taken by canopy fogging at Pithecia, 05 ° 11'S, 74 ° 42'W, Loreto, Peru (May 13–30, 1990; T. Erwin, D. Silva), deposited in MUSM ( PBI_OON 818 ) .

ETYMOLOGY: The specific name is a patronym in honor of one of the collectors, the leading Peruvian arachnologist Diana Silva.

DIAGNOSIS: Males can easily be recognized by the overhanging distal prong and the spiniform proximal prong of the embolus (figs. 211–216), females by the distinctively shaped sclerotization visible through the cuticle at the base of the epigastric scutum (figs. 210, 217) and the wide, rectangular anterior expansion on the anterior genitalic process (fig. 218).

MALE (PBI_OON 821, figs. 148–177, 208, 211–216): Total length 1.69. ALE separated by less than their radius. Sternum surface coarsely reticulate, microsculpture everywhere but front. Endites distally narrowed into sharply pointed projection. Dorsal scutum covering full length of abdomen, no soft tissue visible from above, not fused to epigastric scutum. Postepigastric scutum long, almost rectangular, extending to about 3/4 of abdomen length. Leg spination: femur I p0-0-1; tibiae I, II v4-4-0; metatarsi I, II v2-2- 0. Sperm pore large, narrow, slitlike. Cymbium with distal patch of setae. Embolus ventral portion with very narrow, spiniform, arched projection, dorsal portion with thicker arched projection.

FEMALE (PBI_OON821,figs. 178–207, 209, 210, 217, 218): Total length 1.86. Dorsal scutum covering more than 3/4 of abdomen length, more than 1/2 to most of abdomen width. Postepigastric scutum almost semicircular, extending to about 2/3 of abdomen length. Leg spination: femora: I p0-0-2, r2-1- 0; II p0-0-2, r1-1-0; tibiae: I v4-4-2; II v4-4-1p; metatarsi I, II v3-2-0. Posterior portion of anterior genitalic process surrounded by distinctive basal sclerite, sclerite longer ventrally than dorsally.
