Scaphioides reducta Bryant, 1942: 327 , figs. 6, 8 (female holotype from St. Croix , Virgin Islands, in MCZ; examined).– Platnick and Dupérré, 2010: 9.

Stenoonops reductus: Chickering, 1969a: 21 , figs. 53–58 (first description of male).– Burger, 2009: 346, figs. 17–21, 23H, I).

DIAGNOSIS: Members of this species resemble those of S. granpiedra in having relatively few, small sternal depressions that are “haloed” by distinct edges (figs. 221, 222), but have the proximal portion of the embolus longer than the distal portion (figs. 223, 224) and a larger base of the anterior genitalic process (figs. 228, 229).

MALE (PBI_ OON 26341 View Materials , figs. 220, 221, 223–226): Total length 1.47. Elevated portion of pars cephalica strongly reticulate, sides granulate. ALE separated by less than their radius. Sternum surface finely punctuate, without pits, microsculpture everywhere but front, furrows with rows of small pits, anterior margin with interrupted transverse groove. Endites with rebordered, rounded tip. Proximal portion of embolus larger than distal portion.

Figures 230–239 View FIGS

Stenoonops reductus (misidentification): Chickering, 1969b: 21 (specimens from St. John only).

TYPES: Male holotype, female allotype, plus two male and one female paratypes from Virgin Gorda, no specific locality, Virgin Islands (Aug. 1966; A. Chickering), deposited in MCZ (71676, PBI_ OON 26566 View Materials ) .

ETYMOLOGY: The specific name refers to the previous confusion of this species with S. reducta .

DIAGNOSIS: Members of this species resemble those of S. miches in having the sternum covered with tiny, deep depressions (figs. 231, 232), but have a white abdomen that is not iridescent, a smaller proximal lobe on the embolus (figs. 233, 234), and a wider anterior genitalic process (figs. 238, 239).

MALE (PBI_ OON 21011 View Materials , figs. 230, 231, 233–236): Total length 1.47. Elevated portion of pars cephalica granulate anteriorly, reticulate posteriorly, sides granulate. ALE separated by less than their radius. Sternum surface finely punctuate, without pits, microsculpture everywhere but front, furrows with rows of small pits, anterior margin with interrupted transverse groove. Endite tip with thickened, rounded, posteriorly directed protuberance. Proximal portion of embolus straight, scarcely widened distally.

FEMALE (PBI_OON 1771, figs. 232, 237–239): Total length 1.61. Anterior genitalic process long, wide, distally curved, situated on very short base.
