LECTOTYPE (sex undetermined), designated here, labeled: a) “Riverside / Ariz.”; b) “64”; c) “ HoloTYPE / 3932”; d) A. / Wickhami / Horn; e) MCZ / Type / 33979” ( MCZ ). Additional material examined. ( 79 specimens ). USA : Arizona (Gila, Coconino, Pinal, Yavapai, Maricopa, Pima, Greenlee, and Mohave Counties), California (San Bernardino County). Diagnosis. Stenomorpha wickhami can be distinguished from other members of the furcata group by the dense coating of short erect light brown setae on the dorsum, venter, and legs and the weakly crenulated elytral base. It is superficially similar to Asidina parallela (LeConte) and the two species co-occur in at least part of their ranges. Stenomorpha wickhami differs from A. parallela as per the species group characters, including the larger, well defined protibial spine ( Fig. 10 ), smaller more laterally rounded mentum, and the larger rounded spaces separating the submentum from the postgena. Also, on each elytron S. wickhami has a discal costa, and a marginal costa that is nearly always bifurcated. However, the carina on each elytron of A . parallela appears to be the inner branch of a bifurcated marginal costa, though it is not connected to the raised carinate marginal costa at either end. The discal costa is entirely absent. Remarks. Variation in the bifurcation of the elytral marginal costa in S. wickhami is discussed in Triplehorn and Brown (1971) .
