Scaphiella palmillas , new species Figures 114–132; map 6

TYPE: Male holotype from the Palmillas Mountains, Tabasco, Mexico (Aug. 18, 1945; F. Bonet), deposited in AMNH ( PBI _OON 29866) .

DIAGNOSIS: Males have the distal portion of the endites prolonged as a narrow projection, a slightly thickened palpal femur (fig. 123), and a very long, narrow embolus originating from a ventrally expanded bulb (fig. 122). The female from Chiapas here assigned to the species was not collected together with males, but is a close match in somatic structure and adds only a slight expansion to the relatively extensive distribution shown by the few available males; it resembles those of S. campeche but can be distinguished by the much longer anterior epigynal sclerite (figs. 130–132).

MALE (PBI_OON 29855, figs. 114–123). Total length 1.60. Carapace smooth. Sternum smooth. Endites with small, spiniform anteromedian tip. Abdomen unpatterned, scuta smooth. Palpal femur slightly expanded; embolus long, narrow; bulb expanded ventrally, bulging distally.

FEMALE (PBI_OON 29858, figs. 124–132). Total length 1.45. Endites unmodified. Epigynal atrium wide triangular; anterior sclerite narrow, with pair of rounded posterior sclerotizations; apodemes very short, posteriorly directed.
