The combination of an extremely elongate first article of the leg I tarsus and the tegument covered with clavate setae are observed only in C. carvalhoi sp. nov. , C. longitarsus and C. montanus . The presence of four long tarsal articles on leg I is unique to C. carvalhoi sp. nov. Etymology Patronym honoring Dr Leonardo Carvalho, collector of the type series, for his contributions to arachnology.

Description CARAPACE. Six anterior setae ( Fig. 28A ); frontal process triangular ( Fig. 28C ). Small granules densely scattered between ocular triads and among sulci. Median eyes and median ocular tubercle absent ( Fig. 28A ); lateral eyes well developed, seta posterior to each lateral ocular triad; lateral ocular triad well separated from carapace margin ( Fig. 28A ). STERNUM. Tritosternum projected anteriorly with typical setation, long, surpassing base of pedipalp coxae ( Fig. 28B ); other sternal plaques broad and flat, with pair of setae on lateral borders; pentasternum without setae near membranous region and two setae anteriorly. OPISTHOSOMA. Ventral sacs and ventral sac cover absent ( Fig. 28B ). GENITALIA. Female genital operculum with prominent setae posteromedially and smaller setae near margin; gonopod sucker-like, tubular, unsclerotized from base to apex. Male unknown. CHELICERAE. Small flat tooth on retrolateral surface of basal segment, opposite to bifid tooth; setae absent on retrolateral surface of claw; claw with four teeth; row of six setae on prolateral surface of basal segment; bifid tooth on basal segment with dorsal cusp larger than ventral cusp. PEDIPALPS. Coxal dorsal carina with two setae on margin and without seta encircled by round carina. Femur with three dorsal spines and three ventral spines ( Fig. 28E ); two prominent setiferous tubercles between dorsal spine 1 and proximal margin; setiferous tubercle between ventral spine 1 and proximal margin. Patella with three dorsal spines in primary series ( Fig. 28E ); prominent setiferous tubercle distal to spine I, one-third length of spine I; two ventral spines ( Fig. 28F ); setiferous tubercle between spine I and distal margin. Tibia with ventral spine distally and seta between spine and distal margin ( Fig. 28F ). Tarsus with two dorsal spines, proximal spine one-third length of distal spine ( Fig. 28D ); cleaning organ with 28 setae in ventral row. LEGS. Tibia of leg I with 21 articles; tarsus I with 26 articles; first four tarsal articles up to ten times as long as subsequent articles. Leg IV basitibia with two pseudo-articles, without sclerotized, denticulate margin projecting from apex of articles; trichobothrium bt situated in proximal third of pseudo-article; distitibia with trichobothrium bc situated closer to sbf than to bf , sc and sf series each with five trichobothria. Measurements See Table 2 . Distribution Known only from the type localities. Natural history Epigean in secondary forest and synanthropic in disturbed areas.
