Hentzia fimbriata (F.O. Pickard-Cambridge 1901) 

Fig. 16

This species was adequately described by Richman (1989, pp. 306–307, figs. 37–43), but a few specimens have been collected in the United States, far north of the previously northernmost known record in Nayarit, Mexico. Based on the specimens examined it is possible that H. pima Richman 1989  is a junior synonym of H. fimbriata  , as the photograph of the epigynum ( Fig. 17) of a female collected from east of Sycamore Canyon resembles fig. 65 in Richman (1989), except for the openings, which in the Sycamore Canyon female are typical for H. fimbriata  . The dorsal pattern of the abdomen of H. pima  (Richman 1989, fig. 64) is very similar to that of the female from near Sycamore Canyon. The males collected in Sycamore Canyon and Florida Canyon closely match those of H. fimbriata  . I suspect that H. pima  is based on an slightly aberrant female, especially because of the relatively close geographical proximity of the type specimen from the Baboquivari Mountains. However, more material is needed either to verify H. pima  as a separate species or to synonymize it with H. fimbriata  .
