Type material. Holotype male from La Selva , 10.43333°, -84.01666°, Heredia, Costa Rica, May 11, 2000, C. Viquez, deposited in INBIO PBI_ OON 31121 View Materials   . Paratype: La Selva, 150m, 10.43333°, -84.01666°, Heredia, Costa Rica, Sept. 1, 1992, C. Viquez, 1♀ ( INBIO PBI _ OON 31123 View Materials )   .

Etymology. The specific name is an adjective referring to the long and strong setae in the inner paturon of male chelicerae.

Diagnosis. This species resembles C. puberula   comb. rest. and C. zero   sp. nov. bythe shape of the suprapedicelar region with two strong downwards directed teeth ( Figs 32B View FIGURES 32 , 34F, 49G, 51E, 60G, 63H), can be distinguished from the first by the punctuated pattern of the sternum without any groove ( Figs 31F View FIGURES 31 , 33A View FIGURES 33 , 49F View FIGURES 49 ) and from the last species by the large ridge connecting the two strong suprapedicelar teeth ( Figs 49G View FIGURES 49 , 51E View FIGURES 51 , 60G View FIGURES 60 , 63H View FIGURES 63 ). Males of this species are also close to C. loreto   sp. nov. by the the presence of long and strong sclerotized setae in the inner paturon of male chelicerae ( Figs 49E View FIGURES 49 ̅F), character not possessed by any other species of the group, however can be distinguished from the last species by the shape of the suprapedicelar ridge, which in C. loreto   sp. nov. does not present downwards directed teeth ( Figs 52G View FIGURES 52 , 54G View FIGURES 54 ). Female internal genitalia resembles also C. baja   sp. nov. ( Fig. 42H View FIGURES 42 ), with domed anterior area and squared posterior area, can be distinguished from the last by the trapezoidal chitinized wall area, by the forward positioned receptaculum and the very right-angled posterior corners of the internal genitalia ( Fig. 51F View FIGURES 51 ).

Description. Male ( PBI _ OON 31121 View Materials ). Total length: 1.73. CEPHALOTHORAX: Carapace orange-brown, broadly oval in dorsal view, pars cephalica strongly elevated in lateral view, surface of elevated portion of pars cephalica granulate, sides granulate, with radiating rows of pits; lateral margin without denticles. Clypeus straight in front view, high, ALE separated from edge of carapace by their radius or more, around ALE diameter. Eyes relatively large, 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 semicircular depression in the middle half, posterior margin not extending posteriorly of coxae IV; setae originating from surface. Mouthparts: Chelicerae, endites and labium orange-brown. Chelicerae anterior face unmodified, two pairs of medial strong setae; retromargin without teeth; fangs without tooth-like projections; paturon inner margin with pairs of enlarged setae, laminate groove absent. Labium anterior margin indented at middle. Endites anteromedian part forming a groove between serrula and the apical portion. ABDOMEN: pointed posteriorly; dorsum soft portions pale white. Book lung covers slightly elevated. Pedicel scuto-pedicel region with W-shaped scutal ridge, plumose setae dorsal and lateral of pedicel, scutal ridge medium sized with two strong downwards projected denticles. Dorsal scutum orange-brown, middle surface granulate, sides granulate. Epigastric scutum anterior spiracles secondary openings in an indent forming independent apertures. 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 gently narrowing towards end with subdistal constriction, distal tip long, narrow and sharp pointed; embolar tip with short translucent embolar distal process; embolar prolateral process with narrow sclerotized area and broad translucent dorsal area ( Figs 49H View FIGURES 49 , 50 View FIGURES 50 A-D).

Female ( PBI _ OON 31123 View Materials ). As in male except as noted. Total length: 1.64. GENITALIA: internal genitalia general shape subquadrate, with very short lateral processes, receptaculum rounded ( Fig. 51F View FIGURES 51 ).

Other material examined. BRAZIL: Mato Grosso: Corumbá , -19.00960°, -57.65474°, May 05-08, 1964, B. Malkin, 1♂ ( AMNH PBI _ OON 01166 View Materials )   .

Distribution. This species is know from Costa Rica and Brazil.
