Diagnosis

Based on Mello-Leitão (1931), this species may be separated from other Charinus in eastern South America by means of the following combination of characters: lateral eyes present; tritosternum projecting anteriorly, surpassing base of pedipalp coxae; tetra- and pentasternum with small platelets with seta on each side; pedipalp femur with five dorsal spines and five ventral spines; pedipalp patella with five dorsal spines, long setiferous tubercle between spine I and distal margin, and three ventral spines; pedipalp tarsus with two dorsal spines; tibia of leg I with 23 articles.

Etymology

Patronym honoring P. Schirch ( Mello-Leitão 1931).

Type material

Syntypes BRAZIL • 3 ♀♀; Rio de Janeiro, Teresópolis ; [22°26′04.71″ S, 42°59′00.57″ W]; P. Schirch leg.; MNRJ [not examined] .

Measurements

See Table 4 .

Distribution

Known only from the type locality.

Remarks

The syntypes are lost, hence the diagnosis is based on the original description of Mello-Leitão (1931). The median eyes were not described, but the species was collected in the Atlantic Forest and is not troglobitic; hence, it is assumed to possess a median ocular tubercle with median eyes. Mello-Leitão (1931) described six dorsal spines on the pedipalp patella, but included the long setiferous tubercle in the count; the true count of dorsal spines on the patella is five.
