Heteroonops toro , new species

Figures 354–364

TYPE: Male holotype taken in the Caribbean National Forest, Toro Negro Division, Puerto Rico (Aug. 29, 1967; E. Sabath), deposited in MCZ (71598, PBI_ OON 28101) .

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

DIAGNOSIS: The male palp closely resembles that of H. castellus , but has the tips of the embolus and conductor more widely separated than in that species (figs. 362–364), and the endite projection is longer and differently shaped (figs. 360, 361). The male palp is also remarkably similar to that of Oonops ebenecus Chickering , also from Puerto Rico, but males of that species can easily be recognized by their highly modified cheliceral fangs ( Chickering, 1972: fig. 12). Males of O. ebenecus do have an anterior projection on their endites, but it projects straight out from the endite surface and is not posteriorly directed. It is possible that O. ebenecus is the male of O. viridans Bryant (1942) ; both have been collected at El Yunque and at Mayagüez, Puerto Rico, and were taken on the same day at the latter locality. Females of O. viridans have genitalia that are very different from those of Heteroonops species.

MALE (PBI _ OON 28101, figs. 354– 358): Total length 1.34. Endites each with one posteriorly directed projection (figs. 359– 361). Abdominal venter with pair of subcuticular slightly darkened spots just anterior of spinnerets. Leg spination (legs I, II missing): tibiae: III p0-1-0, v0-1-0, r0-1-0; IV v2-2-0; metatarsi: III d1-0-0, v0-1-0; IV v2-2-0. Embolus smoothly curved, conductor very short, spiniform (figs. 362–364).

FEMALE: Unknown.

OTHER MATERIAL EXAMINED: None.

DISTRIBUTION: Puerto Rico.
