Scaphiella cayo , new species Figures 133–160; map 7

TYPE: Male holotype from a Berlese sample of limestone forest litter taken 2.5 mi S of Belmopan, Cayo, Belize (Aug. 4, 1972; S., J. Peck), deposited in FMNH (33510, PBI _OON 10017) .

DIAGNOSIS: Males resemble those of S. palenque in having a greatly thickened palpal femur, but have a much shorter embolus (fig. 142) and just a narrow prolongation at the tip of the endites. The female (from a nearby locality) here matched with the males resembles them in size and color, but can easily be distinguished by the chelicerae, which lack macrosetae but are distally elongated and bear greatly elongated fangs (figs. 153–156), and by the palpal femur, which is basally only slightly expand- ed and lacks prolateral macrosetae (figs. 157– 160).

MALE (PBI_OON 293, figs. 133–143). Total length 1.24. Carapace smooth. Sternum smooth. Endites with tiny, spiniform anteromedian tip. Abdomen unpatterned, scuta smooth. Palpal femur greatly expanded; embolus short, wide.

FEMALE (PBI_OON 294, figs. 144–160). Total length 1.25. Endites unmodified. Epigynal atrium widely oval, with large, rounded anterior sclerite; apodemes short, posterolaterally directed; dorsal extension of anterior sclerite short, thick; apodemes short, triangular.
