Eremobates vallis species group

Diagnosis:  Muma (1989) established this group to accommodate a single species, Eremobates vallis Muma 1989,  from the cape region of Baja California, Mexico.  He characterized males of the group as having a basal constriction, but no distinct notch, and a dorsal flare, but no ectodorsal tooth-like process, on the fixed cheliceral finger (Figure 1), and a. mesoventral groove in the fixed cheliceral finger that is broad from its apex to its base and occupies most of finger width (Figure 2). The movable finger, he reported, lacks an anterior tooth (Figure 1). Females, he stated, have opercula that are broadly lobate at their posterioectal angles, adjacent mesally for most of their length, with a small, wide and flat opercular notch that occupies a minor portion of opercular area,. and a pair of shallow, distinct pits about midway along their ectal margins (Figure 3).
