Oonopoides endicus (Chickering) , new combination

Figures 12–92 Oonops endicus Chickering, 1971: 209 , figs. 21–23 (male holotype from South Bimini, Bahama Islands, in AMNH; examined); not figs. 24, 25, female (= Oonopoides iviei ).

DIAGNOSIS: Males can be recognized by the abruptly bent tip of the embolus (figs. 43, 46), females by the hypertrophied posterior receptaculum (figs. 89, 90).

MALE (PBI_OON 37975, figs. 12–53): Total length 1.72. Posterior eye row straight from front; ALE separated by more than their diameter. Endites distally excavated, anterior portion with single, strongly protuberant ledge. Postepigastric scutum absent. Leg spination: femora III, IV d1-0-1; tibiae: III p1-1-0, v0-0-2, r1-1-0; IV d1-1-0, p1-0-1, v0-2-2, r1-0-0; metatarsi: III v0-0-1p, r1-1-0; IV p1-1-0, v2-0-2, r1-1-0. Embolar base with long, narrow projection; embolus abruptly bent.

FEMALE (PBI_OON 37975, figs. 54–92): Total length 2.63. Leg spination: femora: III d1-01; IV d1-0-0; tibiae: III p1-1-0, v0-1p-2, r1-1-0; IV d1-1-0, p1-0-1, v0-1p-2, r1-0-0; metatarsi: III v0-0-1p, r1-1-0; IV p1-1-1, v1p-0-2, r1-1-0. Anterior receptaculum small, anteriorly widened, globular; posterior receptaculum hypertrophied, ducts with anterior pair of large, longitudinal loops anteriorly, numerous smaller, transverse loops posteriorly.

Oonopoides iviei , new species

Figures 93–103

Oonops balanus (misidentification): Chickering, 1971: 204 (some males from South Bimini only). Oonops endicus (misidentification): Chickering, 1971: 209, figs. 24, 25 (females only).

TYPE: Male holotype taken on South Bimini, Bahama Islands (May 1951; W. Gertsch, M. Cazier), deposited in AMNH (PBI_OON 51291)

ETYMOLOGY: The specific name is a patronym in honor of Wilton Ivie, who was the first person to collect specimens of Oonopoides in Florida.

DIAGNOSIS: Males resemble those from Bimini described (but probably misidentified) as “ Oonops balanus ” by Chickering (1971: figs. 1–11), but have a longer, more evenly curved embolus (figs. 97, 100); females have a distally narrow anterior receptaculum and a heavily sclerotized, W-shaped anterior margin of the posterior receptaculum (figs. 102,103).

MALE (PBI_OON 37348, figs. 93–101): Total length 1.83. Posterior eye row straight from front; ALE separated by their radius to diameter. Endites distally not excavated, anterior portion with single, rounded, protuberant ledge. Postepigastric scutum absent. Leg spination: femur IV d1-0-0; tibiae: III p0-0-1, v0-1p-2; IV d0-1-0, p1-0-1, v0-1p-2, r0-0-1; metatarsi: III v0-0-2; IV p1-0-1, v0-0-1p, r1-0-1. Embolus gently arched, with basal projection reduced to tiny spur no longer than tiny projections on hyaline conductor.

FEMALE (PBI_OON 1719, figs. 102, 103): Total length 1.97. ALE separated by more than their diameter. Leg spination: femur III d1-0-0; tibiae: III p1-0-0, v1p-0-2, r1-0-0; IV p0-1-1, v0-1r-2; metatarsi: III v0-1p-2; IV p1-0-0, v0-1p-2, r0-0-1. Anterior receptaculum narrow, tubular, posterior receptaculum with heavily sclerotized, W-shaped anterior margin.
