Diagnosis
This species may be separated from C. monasticus sp. nov., C. taboa, C. troglobius, and C. una sp. nov. by the presence of well-developed median and lateral eyes. It differs from C. diamantinus sp. nov., C. euclidesi sp. nov., C. souzai, and C. sooretama sp. nov., in the lower number of teeth on the cheliceral claw: six teeth are present in C. brasilianus whereas more than six are present in the other species.
Etymology
Although unspecified, the species name is evidently an adjective referring to Brazil, the country in which the type locality is located.

Patella with five dorsal spines; spine distal to spine 1, about one-third length of spine 1 (Fig. 48C, E); three or four conspicuous ventral spines, decreasing in size, with small setiferous tubercles and spines forming secondary series between primary series of spines (Fig. 48D, F). Tibia with two dorsal spines; ventral spine situated in distal half, two-thirds length of proximal dorsal spine; two setae between spine and distal margin.

Distribution
Populations of C. brasilianus were collected in several different municipalities, e.g., Aracruz, Aricanga, and Santa Teresa, in the vicinity of the type locality.
Natural history
This species occurs under stones and fallen tree trunks in tropical forest.
