Diagnosis

This species may be separated from other Charinus in eastern South America by means of the following combination of characters: anterior margin of carapace with six prominent, elongated setae; female gonopods sucker-like, length greater than width, opening rounded, each with posterior slit dorsally, margins with fold and small bottleneck below; male gonopods with several long lobes (LoL2 and LoL1) emerging from fistula (Fi); cheliceral claw with ten denticles; pedipalp femur with three or four dorsal spines and four or five ventral spines; pedipalp patella with five or six dorsal spines and three ventral spines; tibia of leg I with 23 articles, tarsus I with 41 articles; leg IV basitibia with four pseudo-articles; distitibia sc and sf series each with six trichobothria.

Etymology

Noun in apposition referring to the Iuiu Municipality , in which the type locality is situated ( Vasconcelos & Ferreira 2016).

Distribution

Known only from the type locality.

Natural history

Specimens were found in two caves, Lapa do Baixão and Toca Fria , which are around 18 km apart. Both caves are located in the Iuiu Municipality (Bahia State, Brazil), in the Caatinga biome, and belong to the Bambuí limestone group. Although other caves in the area were also surveyed, specimens were only found at the two type localities. The surroundings of the entrance to both caves are severely impacted, mainly by agricultural activities, extensive cattle and goat breeding ( Vasconcelos & Ferreira 2016).
