Stenoonops hoffi Chickering, 1969a: 14 , figs. 34–42 (male holotype from Morant Point , St. Thomas Par., Jamaica, in MCZ; examined).

Scaphioides hoffi: Platnick and Dupérré, 2010: 9 .

DIAGNOSIS: Members of this species resemble those of S. campeche , S. gertschi , and S. siboney in having sternal pits only around the furrows (figs. 179, 180) and both tubercles and pits with reticulating ridges on the carapace (fig. 178), but the sides of the carapace have rows of tubercles opposite the leg coxae (fig. 178).

MALE (PBI_OON 362, figs. 178, 179, 181–187). Total length 1.11. Elevated portion of pars cephalica smooth, with both tubercles and reticulating ridges. ALE separated by less than their radius. Sternum surface smooth, covered with large round pits, microsculpture everywhere but middle, furrows with rows of small pits, anterior margin with continuous transverse groove. Endites with rounded tip. Proximal portion of embolus jaw shaped in prolateral view.

FEMALE (PBI_OON 364, figs. 180, 188–190): Total length 1.25. Anterior genitalic process relatively wide, with irregular tip, situated on oval base.

Scaphioides miches , new species

Figures 191–200

TYPES: Male holotype, female allotype, plus two male and two female paratypes taken at cacao farm near Miches, El Seíbo. Dominican Republic (June 22, 2008; V. Ovtsharenko), deposited in AMNH (PBI_OON 371). FIGS. 201–210. Scaphioides phonetus (Chickering) , male (201, 202, 204–207) and female (203, 208–210). 201. Carapace, dorsal view. 202, 203. Sternum, ventral view. 204. Left embolus, prolateral view. 205. Same, retrolateral view. 206. Left palp, prolateral view. 207. Same, retrolateral view. 208. Epigastric region , ventral view. 209. Genitalia, ventral view. 210. Same, dorsal view .

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

DIAGNOSIS: Members of this species resemble those of S. reductoides in having the sternum covered with tiny, deep depressions (figs. 192, 193), but have an iridescent abdomen, a larger proximal lobe on the embolus (figs. 194, 195), and a narrower anterior genitalic process (figs. 199, 200).

MALE (PBI_OON 371, figs. 191, 192, 194–197): Total length 1.41. Elevated portion of pars cephalica granulate anteriorly, coated with deep slits posteriorly, sides granulate. ALE separated by less than their radius. Sternum surface finely punctuate, without pits, microsculpture covering entire surface, furrows with rows of small pits, anterior margin with interrupted transverse groove. Endite tip rebordered, with rounded, posteriorly directed process. Proximal portion of embolus almost as large as distal portion, in prolateral view.

FEMALE (PBI_OON 371, figs. 193, 198–200): Total length 1.54. Anterior genitalic process bent at about half its length, situated on widely oval base.
