Orchestina utahana Chamberlin and Ivie, 1935 View in CoL (male holotype and female allotype from the United States: Utah, west shore of Utah Lake, sifting cottonwood leaves, deposited in AMNH, PBI_OON 51099, 3 male and 4 female paratypes from Utah
Lake, west shore at heron rookery, 1437
m, 40.16667°, -111.95000°, Apr. 08, 1934, Wilton Ivie, deposited in AMNH, PBI_ OON 42586; examined).
NOTE: The original label is missing, but there is an additional one with the inscription “ Orchestina utahana types.” The type locality was revised from the original publication and transcribed onto a new label. A clear label was added to indicate the type status of both specimens.
DIAGNOSIS: Males resemble those of O. obscura by the general appearance and a similar palp, and by having cuticular projections on the cheliceral promargins, but can be distinguished by the paler coloration and the slightly larger PME (compare figs. 3E and 5A). Females resemble those of O. moaba by having external pockets on the epigastric region (figs. 18A, 19A, 21A, E), but can be distinguished by their smaller size and proximity to the pedicel.
MALE (PBI_OON 51099): Total length 1.24.
CEPHALOTHORAX: Carapace (fig. 3E) sometimes with weak pattern of dark pigment on sides. Clypeus slightly sloping forward in lateral view. Posterior eye row straight from front. Sternum with dark stripe on anterior median half (fig. 3G, arrow). Cheliceral promargins with conical projections (as in O. obscura , fig. 5B). Endites without serrula. ABDOMEN: Dorsum with gray netlike pattern (fig. 3A, H), epigastric area pale. LEGS: Yellow. GENITALIA (figs. 15A– C, 20A, B): Embolus short, dark, straight in dorsal view, convex in lateral view (figs. 20A, B); sperm duct with only one loop (fig. 20A).
FEMALE (PBI_OON 51099). Total length 1.19.
CEPHALOTHORAX: Clypeus sloping forward in lateral view. Endites with serrula in single row.
ABDOMEN: Cylindrical; dorsum with white coloration, without pattern in female allotype, other material with brown net-shaped pattern (fig. 3C, D, I). LEGS: Left legs I, II absent. GENI- TALIA (figs. 18A, 19A, 21A, E): Epigastric region with two external pockets near pedicel, internal pockets absent; anterior receptaculum tube shaped, twisted ventrally (fig. 21E), posterior receptaculum present, posterior apodeme divided, formed by two parallel plates.
DISTRIBUTION: West and central United States, Mexico (maps 1 and 2).
