Yumates nesophila Chamberlin, 1924: 595 , figs 26-29 (Male holotype CAS 1380 and female allotype CAS 1381 from Fig Cañon, Puerto Ballandra, Carmen Island (-25.958138, 68.838539), Gulf of California, Mexico, only female allotype examined (PBI_OON 2974); six paratypes, males and females, from same locality, May 12, 1921, J.C. Chamberlin, deposited in CAS and MCZ, not examined; one female paratype from La Paz, Baja California, Mexico, April 11, 1928, deposited in CAS, PBI_OON 2970, examined).

Note. The male holotype and paratypes were not found in CAS or MCZ. Only the female allotype CAS 1381 was examined, but now labelled as San Marcos, Baja California, Mexico with same date and collector of holotype. The examined males from the same locality (San Marcos) match the description of C. nesophila , confirming that they are conspecific with the allotype. The female paratype from La Paz, from the type series, belongs to the C. baja sp. nov., see below.

Diagnosis. Males of C. nesophila comb nov. are very close to males of C. angela comb. nov., C. baja sp. nov., C. laguna sp. nov. and C. sur sp. nov. in general appearance (body color and size, eyes size, clypeus high and abdomen proportional size). The species differ from C. angela comb. nov. ( Figs 35 E-H) by the presence of a heavely sclerotized dorsodistal narrow and downward-curved tip ( Figs 36H ̅I, 37D). Differs from C. laguna sp. nov. and C. sur sp. nov. by the straight angled ventro-distal portion of the conductor ( Figs 36H, I ; 37D ) which is also present at C. baja sp. nov. ( Figs 40H , 41 A-C). The species differ from the last by the wider distal tip of the embolar prolateral process ( Figs 36H ̅I, 37D). Females of this species resembles C. baja sp. nov. and C. laguna sp. nov. by the shape of the internal genitalia with squared chitinized wall area ( Figs 38H , 42H , 48H ), differ from C. baja sp. nov. by the chitinized wall area occupying less than half of the width of the internal genitalia (desconsidering lateral apodemas) and from C. laguna sp. nov. by the more pronounced and domed anterior portion of the internal genitalia (reaching almost the half size of the whole genitalia length).

Description. Male ( PBI _OON 1179).Total length: 1.70. 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. ABDO- MEN: rounded posteriorly; dorsum soft portions pale white. Book lung covers angular in ventral view. Pedicel scuto-pedicel region with straight scutal ridge, plumose setae dorsal and lateral of pedicel. Dorsal scutum orangebrown, 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 forming a subquadrate ventral portion, distal tip hook-like, narrow, curved downwards and distally sharp pointed; embolus with conspicuous dorsal teeth, embolar tip short with short embolar distal process; embolar prolateral process axe-shaped, dorsally excavated with narrow and subdistal translucent dorsal area ( Figs 36H ̅I, 37D).

Female ( PBI _OON 2971). As in male except as noted. Total length 1.68. CEPHALOTHORAX: Mouthparts: paturon inner margin with short inter-digitating setae. GENITALIA: internal genitalia general shape subquadrate, with short lateral apodemes, domed anteriorly, chitinized wall area squared occupying around one third of internal genitalia width ( Fig. 38H ).
