scopulatus
series
Diagnosis: Muma and Brookhart (1988) recognized this series as including those members of the palpisetulosus group in which males possess a palpal scopula (when present only on the metatarsus, the scopula is basal in position). The dorso-ectal process of the fixed cheliceral finger of males is present as a short, rounded to elongate blade or blade-like process that occupies 15 to 30 percent of the finger length. The fondal notch is narrower than the width of the base of the fixed cheliceral finger (finger width/notch width mean = 1.29 to 2.50), and is usually as wide as or wider than long (length/width mean = 0.73 to 1.50). The posterior intermediate tooth of the the movable cheliceral finger is located on the finger margin at the base of the principal tooth, and the anterior tooth is nearly normal or is modified into a tooth-like flange, an angulate flange, a round flange, a low ridge or a bipartite process. The mesal tooth of the movable finger is missing or indistinct. Known females have opercula that are typical of the palpisetulosus group, varying from 1.4-2.0 times as wide as long, with the opercular notch occupying 21-38% of the opercular area and the anterior opercular lobes broad, but not usually distinctly enlarged at their distal ends. Distribution: United States: Arizona, California, Nevada, and Utah with one questionable record from New Mexico. Included species: Notes: Per Muma and Brookhart (1988), most included species are small to moderate sized and well-marked, varying from blackish-brown with dark palpal tarsi and pale leg metatarsi and tarsi, to pale species with palpal tarsi that are distinctly pale or with a pale spot above, and pale leg metatarsi and tarsi. There are 2 dark brown species with a bipartite process on the movable finger of the males, girardi and williamsi. The remaining 14 species are paler and somewhat variable in both color pattern and morphological structure. Five of these are known from unique, single males that do not seem to be closely related to any other species. Nine species, 3 known only from males, 1 known only from females, and 5 known from both sexes, appear to be related to one or more other species of the series. The species of this series are very difficult to identify and place, either because of the paucity of material or because of intraspecific variation . For these reasons, they suggested that the tabular key to species that they included in their paper (see below) may not function adequately in the identification of every collected specimen; rather, they suggested, a series of specimens may be required for accurate placement.
