Chandler, in CNC . Comments: Paschoal (1983c) stated that the holotype of J. bicentenaria is a male, but the slide labelled ‘holotype’ in OSAL is a female and possibly represents a paratype . Joshuella is a distinctive genus of three species known from grasslands in western North America and can be differentiated from other genera by the parallel longitudinal cerotegumental ridges with large pustules on the notogaster ( Fig. 22 ) and the 6 pairs of genital setae. The species are differentiated in the key below.
