Segestria canities McCook, 1890 Emended diagnosis. After Gertsch (1958) , Brignoli (1974) , Platnick (1989) , Grismado & Ramírez (2014) . Members of Diguetia resemble those of Segestrioides by the diamond-shaped endites, females with two lateral pore plates and males with wide, flattened laminate embolus, but Diguetia can be distinguished by the presence of thick white setae on the prosoma and opisthosoma ( Figs 1–8 , 25 , 30–37 , 53 , 56–63 , 67–74 , 85–92 , 103–104 ; absent in Segestrioides ); opisthosoma usually with a middle basal band which continue caudally as two narrow scalloped bands, different pattern in Segestrioides , and the capsulated tarsal organ ( Fig. 23 ; while in Segestrioides it is a typical flattened plate bearing concentric rings). Furthermore, the gonopore in Diguetia is wider than in Segestrioides but it is not situated on a protuberance; the male palpal bulb of Diguetia has a narrow tubular prong associated with the spoonshaped embolus ( Figs 11–17 , 40–46 , 64–65 , 77–82 , 95–100 ; absent in Segestrioides ). The females have a single longitudinal oriented membranous median sac ( Figs 10 , 18–19 , 39 , 47–48 , 76 , 94 ) of unknown function, although Brignoli (1974: 258) refers it as single medial spermatheca; such structure is absent in Segestrioides . Moreover, Diguetia species spin extensive aerial webs in shrubs and cacti with vertical retreats, whereas Segestrioides species dwell under rocks ( Platnick 1989 ). Composition. Diguetia albolineata (O. Pickard-Cambridge, 1895 ) , D. andersoni Gertsch, 1958 , D. balandra sp. nov. , D. canities ( McCook, 1890 ) , D. dialectica Chamberlin, 1924 stat. reval. , D. catamarquensis ( Mello-Leitão, 1941 ) , D. imperiosa Gertsch & Mulaik, 1940 , D. mojavea Gertsch, 1958 , D. propinqua (O. Pickard-Cambridge, 1896 ) , D. signata Gertsch, 1958 , D. stridulans Chamberlin, 1924 . Distribution. Primarily Southwestern United States to North and Central Mexico, and from Argentina ( Ubick et al. 2017 ). Remarks. We emend the generic diagnosis based on the copulatory organs of D. balandra sp. nov. , D. canities , D. dialectica stat. reval. , D. signata , D. imperiosa , and D. catamarquensis .
