Heteroonops murphyorum , new species

Figures 148–168

TYPES: Male holotype and female allotype taken from shrubs and litter at an elev. of 500 m at Laguna de Arenal , Guanacaste, Costa Rica (Aug. 19, 1983; J., F. Murphy), deposited in AMNH (PBI_OON 36756) .

ETYMOLOGY: The specific name is a patronym in honor of the collectors of the types and many other fascinating oonopids.

DIAGNOSIS: Males resemble those of H. spinimanus in having two longitudinally situated projections on each endite (fig. 153), but the posterior projection is smaller (fig. 154); females have a very thin transverse bar on the anterior receptaculum (figs. 166–168).

MALE (PBI _OON 36756, figs. 148 – 152): Total length 1.40. Endites each with two posteriorly directed projections, posterior one not enlarged (figs. 153–155). Abdominal venter with pair of subcuticular dark spots just anterior of spinnerets. Leg spination: femora: I, II d1-0-1; III d1-0-1; IV d1-0-0; tibiae: I, II v0-2-0; III p1-1-0, v0-1-1, r0-1-0; metatarsi: I v0-1-0; II v1-0-0; III v1-2-0, r0-1-0; IV p0-0-1, v1-0-0, r0-0-1; tarsi IV v0-1-1. Embolus long, slightly arched, distal half darkened, conductor shorter, sharply pointed, translucent (figs. 156–158).

FEMALE (PBI_OON 36756, figs. 159– 165): Total length 1.43. Palpal patella prolaterally dilated at half its length. Leg spination: femora: I, II d1-0-0; III, IV d1-0-0; tibiae: I, II v0-2-0; III p0-1-0, v0-2-0; IV p0-1-1, v0-1- 2; metatarsi: I, II v2-2-0; III d1-0-0, v1-2-0, r1- 1-0; IV d1-0-0, p1-1-0, v1p-2-0, r1-1-0. Palpal spination: femur v1-1-0, patella p0-1-1, tibia p1-2-2, v1-1-1, tarsus p1-2-2, v1-1-2. Anterior receptaculum T-shaped, with thin transverse bar (figs. 166–168).
