Gertsch , R. Hastings ), deposited in AMNH (PBI_OON 36863) . ETYMOLOGY : The specific name is a noun in apposition taken from the type locality. DIAGNOSIS : Whether males of this species show palpal asymmetry is unknown; the only available specimen is missing the left palp, but has a distinctively rebordered posterior margin on the endite excavation (figs. 270, 276), a club-shaped palpal femur (fig. 277), and an extremely long, thin embolus (fig. 280). Females have a distinctively widened anterior epigynal sclerite containing an S-shaped darkening (fig. 290), and both sexes seem to have slightly reduced eyes (figs. 272, 288). MALE (PBI_OON 36863): Total length 1.17 (figs. 269, 270, 273). Carapace pale orange, surface of elevated portion of pars cephalica smooth, sides granulate; lateral margins without denticles (figs. 271, 274). Eyes: ALE circular, PME squared; ALE separated by less than their radius, ALE-PLE touching, PME touching throughout most of their length, PLE-PME touching (fig. 272). Sternum pale orange, without radial furrows between coxae I–II, II–III, III–IV, surface smooth, microsculpture absent (fig. 276). Chelicerae, endites, and labium pale orange. Posterior margin of endite excavation rebordered (fig. 276). Abdomen ovoid; book lung covers large, ovoid; pedicel tube medium (fig. 275), scutum extending far dorsal of pedicel; dorsal scutum pale orange, covering full length of abdomen, no soft tissue visible from above, middle surface smooth, sides smooth; postepigastric scutum pale orange, sides smooth. PMS not observed. Legs pale orange. Palp with proximal segments pale orange; embolus dark, greatly elongated (figs. 278–281); femur enlarged, club shaped (fig. 277); cymbium and bulb pale orange, subdistal row of six long, stiff setae marking edge of cymbial area on prolateral side (fig. 279).

PMS present as single median projection (light microscope). Anterior epigynal sclerite containing S-shaped darkening (figs. 283, 287, 290). Figs. 282–290.
