Yumates nesophila Chamberlin, 1924: 595   (Only female paratype from La Paz, Baja California, Mexico, misidentification).

Type material. Male holotype from 4 mi. W El Refugio, 24.45000°, -111.50000°, Feb. 13, 1966, V. Roth, deposited in AMNH ( PBI _ OON 01185 View Materials ). Paratypes: 2♂, 2♀ from 5 mi. W. San Luis Gonzaga , 25.00000°, -111.25000°, Feb. 14, 1966, V. Roth, deposited in AMNH ( PBI _ OON 01182 View Materials ).  

Etymology. The specific name refers to the region of Baja California. It is to be treated as a noun in apposition.

Diagnosis. Males of this species are closest to C. nesophila   comb. nov.; it can be distinguished from the latter by the triangular embolar prolateral process narrowing distally (which in C. nesophila   comb nov. is broader distally) and also by the absence of conspicuous teeth at the dorsal region of embolus ( Figs 40H View FIGURES 40 , 41A View FIGURES 41 ̅D). Females can be distinguished from C. nesophila   comb. nov. by the broader chitinized wall area of the internal genitalia reaching half of the internal genital width ( Fig. 42H View FIGURES 42 ).

Description. Male ( PBI _ OON 01185 View Materials ). Total length: 1.92. CEPHALOTHORAX: Carapace orange-brown, broadly oval in dorsal view, pars cephalica slightly elevated in lateral view, surface of elevated portion of pars cephalica granulate, sides granulate; lateral margin without denticles. Clypeus straight in front view, high, ALE separated from edge of carapace by their radius or more, twice ALE diameter. Eyes relatively small, all subequal; ALE separated by more than their diameter, PLE-PME separated by less than PME radius. Sternum orange-brown, fused to carapace, furrow wrinkled, surface finely punctuate, microsculpture only medially, anterior margin with continuous transverse groove, posterior margin not extending posteriorly of coxae IV; setae originating from surface. Mouthparts: Chelicerae, endites and labium orange-brown. Chelicerae anterior face unmodified; retromargin without teeth; fangs without tooth-like projections; paturon inner margin with brush, laminate groove absent. Labium anterior margin indented at middle. Endites anteromedian part forming a groove between serrula and the apical portion. ABDOMEN: rounded posteriorly; dorsum soft portions pale white. Book lung covers slightly angular in ventral view. Pedicel scuto-pedicel region with straight scutal ridge, plumose setae dorsal and lateral of pedicel, very weak ridge. Dorsal scutum orange-brown, middle surface granulate, sides granulate. Epigastric scutum anterior spiracles secondary openings at level of epigastric furrow in an indent. Postepigastric scutum orange-brown, almost semicircular, fused to epigastric scutum, without posteriorly directed lateral apodemes. Spinneret scutum large. LEGS: orange-brown. GENITALIA: Epigastric region with sperm pore circular, situated in front of anterior spiracles, rebordered. Palp proximal segments orange-brown. Conductor abruptly narrowing towards end forming a subquadrate ventral portion, distal tip narrow and curved downwards, distally sharp pointed; embolar tip with short translucent embolar distal process; embolar prolateral process triangular, dorsally straight and with very narrow translucent area ( Figs 40H View FIGURES 40 , 41A View FIGURES 41 ̅D).

Female ( PBI _ OON 01182 View Materials ). As in male except as noted. Total length: 1.93. CEPHALOTHORAX: Mouthparts: paturon inner margin with short inter-digitating setae. GENITALIA: internal genitalia general shape subquadrate, with short lateral processes and domed anterior portion ( Fig. 42H View FIGURES 42 ).
