Heteroonops castelloides , new species

Figures 242–259

TYPE: Male holotype taken in a flight intercept trap at an elevation of 1100 m in a tropical evergreen forest in the Parque Nacional A. Bermudez, Cienaga, La Vega, Dominican Republic (July 19–Aug. 2, 1995; S., J. Peck), deposited in AMNH (PBI_OON 21069) .

ETYMOLOGY: The specific name refers to the similarities of this species to H. castellus (Chickering) .

DIAGNOSIS: Males resemble those of H. castellus but have a shorter, basally thicker embolus (figs. 249, 250); females resemble those of H. castellus in having a solid, compact posterior receptaculum but have a much longer, more elaborate anterior receptaculum (figs. 257–259).

MALE (PBI _ OON 21095, figs. 242– 246): Total length 1.72. Endites each with one posteriorly directed projection (figs. 247, 248). Abdominal venter with pair of subcuticular dark spots just anterior of spinnerets. Leg spination: femora: I d1-0-0; II d1-0-1; III, IV d1- 0-1; tibiae: III d0-1-0, p1-0-1, v0-0-1, r0-0-1; IV d0-1-0, p1-0-1, v0-1-2, r0-0-1; metatarsi: III v1- 0-2; IV d1-0-0, p1-0-0, v0-0-2, r1-0-0. Embolus basally thickened, then abruptly bent, conductor straight, translucent (figs. 249, 250).

FEMALE (PBI_OON 21095, figs. 251– 256): Total length 1.98. Palpal patella elongated but not prolaterally dilated. Leg spination: femora: III d1-0-0; IV d1-0-1, p0-0-1; tibiae: I v0-0-1; III p1-0-1, r1-0-0; IV v0-1-0; metatarsi: I v0-2-2; III v0-1-0; IV v0-1-1. Palpal spination: femur v1-1-1, patella p1-1-0, tibia 2- 2-3, v0-1-1, tarsus p1-1-1, v1-1-1. Anterior receptaculum with five branches; posterior receptaculum compact (figs. 257–259).

DISTRIBUTION: Puerto Rico and Virgin Islands (St. John, St. Thomas, and Tortola).

SYNONYMY: Chickering (1972: 108) noted that the female of O. delegenus has a palp ‘‘with numerous spines on four terminal segments much like those on Heteroonops spinimanus (Simon) ’’ but nevertheless suggest- ed that the species ‘‘seems to belong in the group of species including Oonops anoxus and Oonops vestus as described in Part I of this series.’’ Even odder is that he correctly identified as O. castellus a male he collected at the type locality of O. delegenus , which (like the females of O. delegenus ) fully matches Virgin Island specimens of O. castellus , rather than the Panama and Trinidad species he mentioned in the diagnosis of O. delegenus .
