Brookhart and Muma 1988:
Eremobates bixleri Muma
and Brookhart new species
Male holotype from Pima Co., Tucson,
Arizona, April 30, 1968, David E. Bixler, deposited in FSCA.
Figures 59 and 60
distinguished by tiny triangular dorso-ectal spur on fixed cheliceral
finger; rounded, but apically notched process on movable cheliceral
finger; no ctenidia; palpi
dusky on metatarsal tips and all of tarsi. Dorsal process of fixed
cheliceral finger peaked over
distal half of fondal notch.
Females known from a single badly fragmented , previously dehydrated
specimen from Tucson,
Species pale to dusty yellow in color
with dusky purplish markings as follows. Palpi pale yellow basally to
dusty yellow distally with distal 1/4 of metatarsi and all of
tarsi dusky. Legs pale yellow with femoral-tibial union of leg IV dusty
yellow to dusky. Propeltidia
dark along anterior margin with dusky marking and pale area as on
Mesopeltidia, metapeltidia, and abdominal
terga dusky with pleura
pale. Sterna pale.
Males (3) relatively uniform in size; CP varies from 9. 1- 10.6 (mean
10.1). Legs long; A/CP varies from 6.4-6.9 (mean 6.7). Fondal notches
slightly longer than wide; length/width ratio was same for all 3
specimens, 1.3 (fig. 59). No ctenidia. Mesal tooth on movable cheliceral
finger varies from small to large; mode small.
Single female designated here too badly dessicated and fragmented to
permit accurate description; opercula
All 3 of our male study specimens and
the single female from Tucson, Arizona, collected between April 20
and June 2. See Plate XIX.
Paler coloration, pale, less distinct markings, and distinctly notched
anterior process on movable cheliceral finger presently distinguish this
species from ajoanus.
Ventral notch of movable cheliceral finger completely obscured from a
lateral view for this species, and may also prove diagnostic.
