Orchestina moaba Chamberlin and Ivie, 1935: 10 , pl. 2, figs. 10–13, pl. 3, figs. 15–18 (male holotype and female allotype from the United States, Moab, Utah, should be deposited in AMNH, presumably lost, see below). – Wunderlich, 1986: 167, fig. 56 (m) – Wunderlich, 1988: 57, fig. 46 (m).

NOTE: The type material was not examined, either because is lost or is mixed with other material with no indication. Three vials are coincident with the type locality (Moab, Utah), one of them ( PBI _OON 42824) with 23 and 16♀, a second ( PBI _OON 42825) with only one male, and a third vial ( PBI _OON 42573) with 43 and 5♀ labeled as “ paratypes.” Note that Chamberlin and Ivie designated a female allotype but no paratypes. The illustrations in the original description are consistent with this material and the rest of the studied specimens.

DIAGNOSIS: Males can easily be separated from the other North American species by having a depressed area behind the eyes covered with patch of short setae (fig. 4D, E). Additionally, the proximal part of tibiae I is swollen, covered with long, needlelike setae (fig. 4F) and probably with pores (as in O. quasimodo , see below). Females resemble those of O. utahana in having external pockets on the epigastric region, but in O. moaba these pockets are larger and are placed near epigastric fold (figs. 18B, 19B, 21B).

MALE (PBI_OON 1073): Total length 0.98.

CEPHALOTHORAX: Carapace orange, margins of carapace brown or purple; cephalic region with depression covered with patch of setae (fig. 4A, D, E, G). PME circular. Sternum with dark pigment on sides, anterior margin with dark sclerotized band originating at base of labium (fig. 4B). Endites without serrula. ABDOMEN: Dorsum with gray netlike pattern (fig. 4A, G).

LEGS: Tibiae I proximal end swollen, with long, needlelike setae (fig. 4F). GENITALIA (figs. 15D–F, 20C, D): Palp proximal segments yellow; bulb yellow, spherical; embolus short, dark, straight in dorsal view, slightly convex in lateral view; sperm duct with only one loop.

FEMALE (PBI_OON 1079): Total length 1.37. CEPHALOTHORAX (fig. 4C): Endites with serrula in single row. LEGS: Patella plus tibia I shorter than carapace. GENITALIA (figs. 18B, 19B, 21B): Epigastric region with large external pockets near epigastric fold, internal pockets absent; anterior receptaculum short, twisted ventrally, posterior receptaculum present, massive; posterior apodeme divided, formed by two parallel plates.

DISTRIBUTION: Known from the west and central region of United States (map 1).
