Scaphiella pich , new species Figures 630–648; map 4

TYPES: Male holotype and female allotype from a Berlese sample of forest litter taken at an elevation of 700 ft at Río Palenque Station, 47 km S of Santo Domingo, Pichincha, Ecuador (May 18–30, 1975; S., J. Peck), deposited in FMNH ( PBI _ OON 322 ) .

DIAGNOSIS: Males resemble those of S. bocas in having a basally originating embolus but differ in having a prominent knob on the palpal bulb at about one-quarter of its length (figs. 638, 639); females have a distinctively widened anterior epigynal sclerite that fills most of the width of the epigynal atrium (figs. 646–648).

MALE (PBI_OON 322, figs. 630–639). Total length 1.25. Carapace with granulations restricted to lateral and posterior margins of pars thoracica. Sternum smooth. Endites with strong toothlike projection bearing spiniform anteromedian tip. Abdomen with dark markings visible under scuta, scuta smooth. Palp femur moderately expanded; bulb with knob at about half its length; embolus long, extending from near base of cymbium to past its tip.

FEMALE (PBI_OON 323, figs. 640–648). Total length 1.40. Endites unmodified. Anterior epigynal sclerite widened, filling much of atrium, with invaginated posterior margin; apodemes directed laterally.
