Paradysderina apurimac , new species Figures 158–173

TYPE: Male holotype from Río Apurimac, Llactohuaman, 12 ° 519S, 73 ° 309W, Cusco, Peru (July 11–29, 1998; J. Duárez, S. Córdova), deposited in MUSM (501448, PBI_OON 540) .

ETYMOLOGY: The specific name is a noun in apposition taken from the type locality.

DIAGNOSIS: Males and females have not been taken together, and may be mismatched. Males can be recognized by the long, narrow embolus, which resembles those of Scaphiella species and has the ventral prong reduced to a small tubercle (figs. 163, 164), females by the sclerotized lateral margins of the genitalic atrium (figs. 171– 173), which is greatly widened and occupies most of the space between the anterior spiracles.

MALE (PBI_OON 540, figs. 158–165): Total length 1.47. Elevated portion of pars cephalica appears reticulate. Chilum triangular. Paturon with anterior ledge bearing dorsally directed process at its dorsomedian edge, plus long, thin, heavily sclerotized spine directed toward chilum. Endites anteriorly with two short, curved, clawlike processes. Leg spination: femur I p0-0-2; tibiae: I v4-4- 1p, II v4-4-0; metatarsi: I v2-2-1p, II v2-2-0. Palps symmetrical; embolus with ventral flange reduced to small tubercle, dorsal flange narrow, elongate.

FEMALE (PBI_OON 113, figs. 166–173): Total length 1.69. Postepigastric scutum covering about one-third of abdomen length, fused to epigastric scutum. Leg spination: femur I p0-0- 2; tibiae: I v4-4-2, II v4-4-1p; metatarsi I, II v2- 2- 1p. Genitalic atrium very wide, laterally sclerotized, median one-third occupied by rectangular anterior genitalic elements.
