Simonoonops chickeringi , new species

Figures 168–181

Dysderina principalis (misidentification): Simon, 1891: 557 (in part, some specimens from Saint Vincent only).

Dysderina soltina (misidentification): Chickering, 1968: 31, figs. 74, 75 (female only).

TYPES: Male holotype and three female paratypes from Saint Vincent, no specific locality, deposited in BMNH (PBI_OON 673) .

ETYMOLOGY: The specific name is a patronym in honor of Arthur Chickering, in recognition of his many contributions to our knowledge of goblin spiders.

DIAGNOSIS: Members of this species resemble those of S. soltina but have much weaker transverse ridges on the sternum (fig. 170), a wider embolus (figs. 173–175), and a smaller sclerotization in the female genital atrium, paired with a weaker transverse bar connecting the apodemes (figs. 179–181).

MALE (PBI_OON 673, figs. 168–175): Total length 1.52. Posterior half of pars cephalica with pair of elongate, oval, paramedian light areas, surface of anterior portion of pars cephalica reticulate, posterior portion smooth. Chilum short, triangular. Endites with ventral process distinctly set off from remainder of endite by strip of lightly sclerotized cuticle, almost diamond shaped, dorsal process narrow. All femora darkened. Leg spination: femur I p0-0-2; tibiae: I v4-3-0, II v4-4-0; metatarsi: I v2-2-1p, II v2-2-0. Embolus with elaborate, translucent dorsal flange, conductor short, with blunt tip.

FEMALE (PBI_OON 673, figs. 176–181): Total length 1.87. Posterior portion of pars cephalica with U-shaped smooth area surrounding median reticulate area. Leg spination: femora: I p0-0-2, r0-2-1, II p0-0-2, r0-2-0; tibiae I, II v4-4-1p; metatarsi: I v2-2-1p, II v2-1p- 2. Atrium oval, posterior margin relatively thin, internal sclerotization surrounded by unsclerotized areas at side, narrower unsclerotized area anteriorly, only narrow anterior genitalic process visible through cuticle.

OTHER MATERIAL EXAMINED: Windward Islands: Saint Vincent: no specific locality (BMNH PBI_OON 674, paratype of Dysderina soltina Chickering , originally misidentified as Dysderina principalis by Simon, 1891), 1♀, (MNHN PBI_OON 675, originally misidentified as Dysderina principalis by Simon, 1891), 1♀.

DISTRIBUTION: Windward Islands ( Saint Vincent).
