Noonops mortero , new species

Figures 153–163

TYPES: Male holotype, female allotype, and female paratype taken under rocks and thatch in a palm grove at Mortero Palms , south of Dos Cabezas, Anza-Borrego Desert State Park , San Diego , California (Mar. 26, 1991; D. Ubick), deposited in CAS (PBI_OON 35676) .

ETYMOLOGY: The specific name is a noun in apposition taken from the type locality.

DIAGNOSIS: Males can easily be recognized by the enlarged, sharply bent basal process on the embolus (figs. 153–158), females by the long anterior receptaculum set on a strongly arched base (figs. 162, 163).

MALE (PBI_OON 35676, figs. 153–160): Total length 1.39. Anterior portion of endites with single anterior process situated distally, directed anteriorly; serrula absent. Leg spination (leg III missing): tibia IV v0-0-2; metatarsus IV v0-0-2. Embolus with basal process greatly elongated.

FEMALE (PBI_OON 35676, figs. 161–163): Total length 1.72. Leg spination: tibiae: III v0-0-1p; IV v0-0-2; metatarsi: III v0-0-1r; IV v0-0-2. Anterior receptaculum elongated, situated anterior of wide, recurved sclerotization.

OTHER MATERIAL EXAMINED: One female taken in a Neotoma rodent nest on Magee Road, Tucson, Pima Co. , Arizona, Nov. 10, 1960 (A. Aschwanden, AMNH PBI_OON 38489) was damaged during digestion, but may belong to this species, as it also seems to have an elongated anterior receptaculum but not more posteriorly situated, heavily sclerotized median elements. However, another damaged female taken in the same habitat has those median sclerotized elements and seems to belong to N. sonora instead, and thus possibly the median elements were simply lost during preparation of specimen 38489.

DISTRIBUTION: San Diego Co., California (possibly east to Pima Co. , Arizona) .

TYPES: Male holotype, female allotype, and female paratype taken 2 miles north of Chapulhuacán, 21°11′N, 98°57′W, Hidalgo, Mexico (Aug. 18, 1964; J., W. Ivie), deposited in AMNH (PBI_OON 37982) .

ETYMOLOGY: The specific name is a noun in apposition shortened from the type locality.

DIAGNOSIS: Males resemble those of N. taxquillo but have a smaller projection on the base of the embolus (figs. 290–295); females resemble those of N. mesa but have smaller lateral sclerites at the base of the anterior receptaculum (figs. 299, 300). Both sexes have spines on the prolateral surface of the palpal patella and tibia (fig. 293) that resemble those found in the species of Heteroonops Dalmas.

Embolar base with short, sharp projection, tip angular.

FEMALE (PBI_OON 37982, figs. 298–300). Total length 1.56. Female palp with spines: patella p1-1-0; tibia p1-1-1. Leg spination: femora III, IV d1-0-1; tibiae: III d0-1-0, p1-0-0, v0-1p-2, r1-0-0; IV d0-0-1, p0-0-1, v1p-1p-2, r1-0-1; metatarsi: III v0-1p-2, r1-0-1; IV d1-0-1, p1-0-1, v0-1p-2, r1-0-1. Anterior membrane angular, anterior receptaculum greatly widened at tip, posterior sclerotization Y-shaped.
