Eremobates ajoanus Muma and Brookhart 1988

Eremobates ajoanus Muma and Brookhart, 1988: 19-21, figs 53-58; Brookhart and Brookhart, 2006: 308.

HOLOTYPE: United States.

TYPES: Male holotype at night lights, Child's Ranch, 4.5 mi. south of Ajo, Arizona along Highway 85, June 3, 1975, and female allotype at night lights, 1.2 miles north of Organ Pipe National Monument along Highway 85, June 3, 1975, J. O. Brookhart and M. H. Muma, both deposited in FSCA.

Original description:
Brookhart and Muma 1988:

Species pale to dark yellow in color with dark purplish markings as follows. Palpi yellow basally to dark yellow distally with distal 1/4- 1/2 of metatarsi and all of tarsi dark (fig. 53). Legs pale yellow basally to yellow distally with femoral-tibial unions lightly dusky on legs IV, III and sometimes II (fig. 53). Propeltidia dark along anterior margin, lightly dusky throughout with wide marginal posterior pale area, pale transverse ovate area on each side of eyes, large pale longitudinal ovate area behind eyes, and narrow yellow longitudinal stripe extending from eye tubercle to posterior margin (fig. 54). Mesopeltidia, metapeltidia. and abdominal terga dusky to dark with pleura paler to pale. Sterna pale.
Males (6) somewhat variable in size; CP varies from
9.5-12.8 (mean 10.9). Legs long; A/CP varies from 6.4-7.2 (mean 6.9). Fondal notch slightly longer than wide with length/width ratio varying from 1.1-1.5 (mean 1.4) (fig. 55). No ctenidia. Mesal tooth on movable cheliceral finger varies from medium sized to large with mode medium sized.
Females (6) also somewhat variable in size; CP varies from
10 .8- 13.0 (mean 11.88). Legs short; A/CP varies from 5.6-5 .9 (mean 5.7). Mesal tooth on movable cheliceral finger varies from small to medium sized with mode medium sized (figs. 56-57). Opercula 1.5 times wider than long; opercular notch occupies 29-38% of the opercula (mean 33) (fig. 58).

SUBSEQUENT ACCOUNTS:

DISTRIBUTION: Brookhart and Muma 1988: We have examined 8 males and 7 females of this species from the Organ Pipe Cactus National Monument, Ajo, and Gila Bend area of Arizona. All of our specimens were collected during June. The species probably ranges from southcentral through southwestern Arizona. See Plate XIX.

nOTES:

In a diagnosis, Muma and Brookhart (1988) commented that males of this species may be distinguished by the tiny triangular dorsal-ectal spur on fixed cheliceral finger, an irregular rounded or indistinctly lobed anterior process on movable cheliceral finger, no ctenidia, palpi that are dark apically on their metatarsi and all of their tarsi, and a cheliceral finger  whose dorsal process is peaked over the distal end of fondal notch.  Females, they noted, can be  distinguished by the mesally undulate anterior lobes of their opercula, the anteriorly concave and posteriorly convex lateral margins of their small posterior opercular notch, and a vulvular opening that is located essentially at the posterior end of the opercular area.  They suggested that his species and bixleri are either very closely related or synonyms, but stated that, until more specimens of the latter are available for study, they would maintain them separately.
