Escaphiella exlineae , new species Figures 816–829 ; map 17

TYPE: Male holotype from the Pariñas Valley, 15 mi NE Negritos, Piura, Peru (Oct. 16, 1938; D. Frizell and H. Exline Frizell), deposited in CAS (9026652, PBI_OON 2674) .

ETYMOLOGY: The specific name is a patronym in honor of Harriet Exline, one of the collectors of the holotype.

DIAGNOSIS: Only the left palp of the holotype is present, so palpal asymmetry cannot be assessed, but the palp resembles that of E. gigantea in having a relatively long embolus (figs. 824–827), oriented obliquely, situated on a relatively long embolar base (although the body is much smaller, with lighter coloration). The dorsal abdominal scutum is relatively long and narrow (fig. 816), and the setal bases form tiny denticles, most pronounced on the most anterior setae (fig. 819). The fourth leg is also longer than in other members of the group (fig. 820).

MALE (PBI_OON 2674): Total length 1.71 (figs. 816, 817, 820). Carapace orange-brown, surface of elevated portion of pars cephalica smooth, sides granulate; lateral margins with blunt denticles (figs. 818, 822). Eyes: ALE circular, PME squared; ALE touching, ALE-PLE touching, PME touching throughout most of their length, PLE-PME touching (fig. 819). Sternum pale orange, without radial furrows between coxae I–II, II–III, III–IV, surface smooth, microsculpture absent (fig. 829). Chelicerae, endites, and labium pale orange. Endites anteromedially with long, pointed tip (fig. 828). Abdomen ovoid; book lung covers small, elliptical; pedicel tube medium, ribbed, scutum extending far dorsal of pedicel, anterior spiracles apparently connected by groove (figs. 821, 823); dorsal scutum orange-brown, covering full length of abdomen, no soft tissue visible from above, middle surface striated, sides striated; postepigastric scutum pale orange, long, semicircular, sides smooth. Legs pale orange (leg I missing).

Palp proximal segments pale orange; embolus dark, long (figs. 824–827); femur normal size; cymbium and bulb pale orange.

FEMALE: Unknown.

OTHER MATERIAL EXAMINED: None.

DISTRIBUTION: Known only from Peru (map 17).
