Eremobates aztecus species group

Diagnosis:

Muma (1970) erected this group to accommodate a single species, Eremobates aztecus Pocock 1902. In a key to the species groups of Eremobates (based on males), Muma, (ibid), characterized males of this group as having a fixed cheliceral finger that, in dorsal view, lacks a wide basal notch, and has the mesal groove mesodorsal in position (Figure 1). Muma later (1989) , in a key to species groups of Eremobates based on females, credited females of the group as having opercula that are widely separated posteriorly with a pair of deep, distinct pits about midway along their ectal margins, and a posteriomesal notch that is wide, long (occupying at least a third of opercular area), and sinuate or weakly lobate mesally (Figure 2).


Literature accounts:


Muma 1989: 6-7 (key):


"Females of palpisetulosus, aztecus, and vallis groups have opercula pitted and alate laterally but variable in size and form."


(Male) Mesal groove of fixed cheliceral finger mesodorsal in position ........ aztecus group


(Female) Opercula widely separated posteriorly and/or slightly to distinctly lobate at posterio-ectal angles and with a pair of distinct pits about midway along ectal margins....
Posteriomesal notch wide and long, occupying at least a third of opercular area, pits deep....
Posteriomesal notch of opercula sinuate or weakly lobate mesally within the notch ..........................................................................................................................azteca group
