palpisetulosus series

Diagnosis:  Muma and Brookhart (1988) recognized this series as including those members of the palpisetulosus group having the following characteristics: Males without palpal scopula; with dorsal process of fixed cheliceral finger a posteriorly elevated elongate ridge that occupies 25-35% of finger length; fondal notch nearly as wide as or wider than base of fixed cheliceral finger (finger width/notch width mean = 0.96 to 1.33) and as wide as long or slightly to distinctly longer than wide (fondal notch length/width mean = 1.0 to 1.87); anterior tooth of movable cheliceral finger composed of a more or less basally flattened ridge and apical conical process; basal intermediate tooth  of movable cheliceral finger located in basal angle where principal tooth meets dorsal margin of finger; mesal tooth of movable cheliceral finger small to large and distinct. Females with opercula typical of the palpisetulosus group, varying from 1.5- 1.8 times wider than long, with opercular notch occupying 17-51 % of opercular area, and anterior opercular lobes tapered to a rounded distal point. Vulvular opening transverse, narrow to wide, and located in posterior half of notch with fold extending nearly to posterior margin of opercula.

Distribution: United States: eastern Arizona, Colorado, Kansas, Nebraska, New Mexico, Oklahoma, western Texas,  and southeastern Utah. 

Included species:

Notes:  Muma and Brookhart (1988) noted that the species of this series may be categorized on the bases of both male and female characters, but the resulting groups are not parallel. They reported that males of  marathoni, bajadae, and texanus are large; bantai and norrisi are small; and  palpisetulosus, kiseri, and polhemusi are moderate and nearly equal in size.  Excluding the abdomens, palpisetulosus, bajadae, marathoni, kiseri, and texanus have males larger than females; bantai and norrisi have females larger than males. Males of palpisetulosus, bajadae, marathoni and polhemusi have the peak of the dorsal process of the fixed cheliceral finger occurring over the distal half of the fondal notch; those of norrisi, kiseri, texanus, and bantai have the peak over the basal half. Females of palpisetulosus, bantai,and kiseri have the vulvular openings narrow and crescentic; those of bajadae. marathoni, norrisi, and texanus have the openings wide and bowed. Females of polhemusi were unknown at the time of their writing.
