Oonops trapellus Chickering, 1970: 501 , figs. 27– 29. Male holotype from Trinidad and Tobago: Trinidad: Arima: Arima Valley, Simla , Apr. 19, 1964, A. Chickering ( MCZ 23324 PBI _ OON 36844 ) , and one male paratype from Trinidad, 10.41032 °, - 61.69009 °, Apr. 19, 1964, A. Chickering ( MCZ 66779 PBI _ OON 36843) , examined. Deposited in MCZ.

DIAGNOSIS: N. trapellus males are recognized by the shape of the conductor, sharp, spinelike, with dorsobasal swelling (figs. 107B– D, 109F), and females by the widely expanded and rounded distal part of the anterior receptacle, combined with very thin transverse ridges (fig. 109E).

DESCRIPTION: MALE (holotype, PBI_OON 36844). Total length 1.80. Cephalothorax: Carapace yellow-brown, broadly oval in dorsal view, pars cephalica strongly elevated in lateral view, anteriorly narrowed to between 0.5 and 0.75 times its maximum width; lateral margin straight; nonmarginal pars cephalica setae absent, seem to be lost (bases remain); nonmarginal pars thoracica setae absent; marginal setae dark, needlelike. Clypeus setae dark, needlelike. Eyes: all subequal, ALE circular, PME oval, PLE circular; posterior eye row straight from front; ALE separated by more than their diameter, ALE-PLE touching, PME touching throughout most of their length, PLE-PME separated by less than PME radius. Sternum as long as wide, yellowish white, anterior margin unmodified, posterior margin not extending posteriorly of coxae IV; setae sparse, evenly scattered. Mouthparts: chelicerae, endites, and labium yellowish white; cheliceral setae light, evenly scattered. Labium anterior margin indented at middle; with six or more setae on anterior margin. Endites distally excavated, anteromedian tip with one strong, toothlike projection (fig. 106E). Abdomen: Dorsum white. Book lung covers round. Postepigastric scutum white. Spinneret scutum absent. Dorsum setae dark, needlelike. Colulus represented only by setae. Legs: Yellow-brown; femur IV thickened, much larger than femora I–III (fig. 106C). Leg spination: leg I: femora d0-0- 1, tibiae v2-2-2-2-2-0, v2-2-2-2; leg II: tibiae v2-2-2-2-2-0, v2-2-2-2; leg III: femora d1, tibiae p1-1, v2ap, metatarsi p1-1, v2ap; leg IV: femora d1; tibiae p0-1, v1-2ap; metatarsi p1-1, v1-2ap. Trichobothria not examined. Genitalia: Palp proximal segments yellowbrown; femur normal size, two or more times as long as trochanter; cymbium yellowbrown, ovoid in dorsal view, not fused with bulb; bulb white, 1 to 1.5 times as long as cymbium, slender, tapering apically; conductor spinelike, distally attenuated, basally with translucent flange; embolus dark (figs. 107B– D, 109F).

FEMALE (PBI_OON 1696). Total length 2.57. As in male except as noted. Cephalothorax: Carapace pale orange; nonmarginal pars cephalica setae dark, needlelike, scattered. Eyes: the ocular area is slightly damaged in this specimen. Sternum pale orange, precoxal triangles present; setae dark. Mouthparts: chelicerae, endites, and labium pale orange. Labium elongated hexagon. Palp spines absent. Abdomen: Dorsum pale white. Postepigastric scutum pale orange. Postepigastric area setae dark, needlelike. Legs: Pale orange; patella plus tibia I nearly as long as carapace. Leg spination: leg I: femora d0-1-1-1, tibiae v2-2-2-2-2-2-0, metatarsi v2-2-2-2; leg II: femora d0-1-1-1, tibiae v2-2-2-2-2-2-0, metatarsi v2-2-2-2; leg III: femora d0-1-1-1-1, tibiae p1-1, r1-1, v1-0, d1, metatarsi p1-1, v0-1-1-2ap, r1-1; leg IV: femora d0-1-1-1, tibiae d1, p1-1, v0-1-2ap, r1- 1 metatarsi d1-0-1, p1-1, v0-1-2ap, r1ap. Genitalia: Anterior receptacle elongated, with widened, rounded distal part (appearing orange in ventral view, fig. 108H); with presumably glandular tissue visible at base (fig. 109E); uterus externus opening Vshaped, with thickened margins; basal ridges very thin, gently procurved; posterodorsal plate surpassing anterior receptacle, covering it completely in dorsal view (fig. 109E).
