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

Diagnosis. The species resembles C. adaga   sp. nov.; males can be distinguished from the species above by the shape of the embolic complex with a narrower conductor tip and the large dorsal tooth at embolus ( Figs 73G, H View FIGURES 73 ); females can be distinguished from C. adaga   sp. nov. by the shape of the internal genitalia with posterior lip-like border ( Fig. 75H View FIGURES 75 ).

Description. Male ( MACN PBI _ OON 25675 View Materials ). Total length: 1.70. CEPHALOTHORAX: Carapace dark redbrown, broadly oval in dorsal view, pars cephalica strongly elevated in lateral view, surface of elevated portion of pars cephalica smooth, sides granulate, granulation only evident near borders of carapace; lateral margin without denticles. Clypeus straight in front view, high, ALE separated from edge of carapace by their radius or more, less than AME diameter. Eyes relatively large, all subequal; ALE separated by their radius to diameter, PLE-PME separated by less than PME radius. Sternum dark red-brown, fused to carapace, furrow wrinkled, surface smooth, microsculpture absent, anterior margin with continuous transverse groove, posterior margin not extending posteriorly of coxae IV; setae originating from surface. Mouthparts: Chelicerae, endites and labium dark red-brown. Chelicerae anterior face with swelling; retromargin without teeth; fangs without tooth-like projections; setae antero-medial brush of long forward directed setae; paturon inner margin with scattered setae, 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 absent. Dorsal scutum dark red-brown, middle surface punctate, sides punctate. Epigastric scutum anterior spiracles secondary openings at level of epigastric furrow under a fold, inconspicuous. Postepigastric scutum dark red-brown, almost semicircular, with short posteriorly directed lateral apodemes. Spinneret scutum large. LEGS: orange-brown. GENITALIA: Epigastric region with sperm pore oval, situated in front of anterior spiracles, rebordered. Palp proximal segments orangebrown. Conductor narrowing towards end distal tip downwards curved; embolar tip a short translucent tube with longer embolar distal process; embolar prolateral process with basally broader translucent dorsal area ( Figs 73G View FIGURES 73 ̅H, 74A̅D).

Female ( IBSP ex MACN PBI _ OON 25678 View Materials ). As in male except as noted. Total length: 1.89. CEPHALOTHO- RAX: Mouthparts: paturon inner margin with short inter-digitating setae. GENITALIA: internal genitalia general shape subquadrate, lateral apodemes long and curved, slightly rounded anterior area, receptaculum cavity expanded posteriorly into a lip-shaped border ( Fig. 75H View FIGURES 75 ).
