Type material. Holotype male and paratype female from 7 mi E San Blas , 21.54288°, -105.17530°, Nayarit, Mexico, July 27, 1964, W. Gertsch, J. Woods deposited in AMNH PBI_OON 169 . Paratypes: 7 mi E San Blas , 21.54288°, -105.17530°, Nayarit, Mexico, July 27, 1964, W. Gertsch, J. Woods, 4♂, 4♀ ( AMNH PBI _ OON 01361)

Etymology. The specific name refers to the type locality. It is to be treated as a noun in apposition.

Diagnosis. Males are close to C. nesophila comb. nov. and C. baja sp. nov. by the shape of the ventrodistal area of the conductor presenting a right angled edge ( Figs 36H, I ; 37D ; 40H ; 41 A-C) but differs from the above cited species by the strong sclerotized C-shaped and blunt dorsoanterior tip of the conductor ( Figs 55H , 56A, D ), which in both other species is narrowing towards end ( Figs 36H , 37D ). Females resembles C. nesophila comb. nov., C. baja sp. nov. and C. laguna sp. nov. by the rectangular shaped internal genitalia ( Figs 38H , 42H , 48H ) but can be distinguished from the above by the absence of the ventral chitinized wall area ( Fig. 57H ).

Description. Male ( PBI _OON 00169). Total length: 1.85. 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, near one and a half times ALE diameter. Eyes all subequal; ALE separated by more than their diameter, PLE-PME separated by less than PME radius. Sternum orange-brown, fused to carapace, furrow with rows of small pits, surface finely punctuate, microsculpture medially and in furrows, anterior margin with continuous transverse groove, posterior margin not extending posteriorly of coxae IV, enlarged hair basis posteriorly; 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 elevated. Pedicel scuto-pedicel region with paired curved scutal ridges, plumose setae lateral of pedicel. Dorsal scutum orange-brown, middle surface granulate, sides granulate. Epigastric scutum: anterior 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, with clear seam at furrow. 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 curved downwards forming hook-like process with distal stout tip. Embolar tip a short translucent tube with longer embolar distal process; embolar prolateral process curved dorsally, narrow and with narrow translucent dorsal area ( Figs 55H , 56A ̅D).

Female ( PBI _OON 01361). As in male except as noted. Total length: 2.09. Mouthparts: paturon inner margin with short inter-digitating setae. GENITALIA: internal genitalia subquadrate, anterior area rounded, slightly protuding, lateral apodemes short, receptaculum rounded ( Fig. 57H ).

Other material examined. USA: Arizona: Galiuro Mountains (32°30’22, 32” N 110°16’47, 28” W), 2♂ ( USNM 2046648 PBI _ OON 27919) . MEXICO: Nayarit: San Blas , 21.54108°, -105.28346°, Aug. 6, 1947, C., M. Goodnight, B. Malkin, 1♀ ( AMNH PBI _ OON 01412) .

Distribution. This species is known from southern USA and Mexico.
