Charinus ferreus Giupponi & Miranda, 2016: 21–23, figs 2g, 3g, 4h, 10a–f.

Diagnosis

Based on Giupponi & Miranda (2016), this species may be separated from other Charinus in Amazonia and northern South America by means of the following combination of characters: tegument pale yellow; median eyes and median ocular tubercle absent; lateral eyes reduced and pale; small, rounded tetra- and pentasternum; reduced tritosternum, slightly surpassing base of pedipalp coxae; male gonopod with long, curved, wrinkled medial lobes; lateral lobe fimbriate; median lobe surpassing lateral and dorsal lobes; female gonopod cushion-like; pedipalp femur with three dorsal spines; spines of pedipalp tibia subequal; basal spine of pedipalp tarsus large, ca two-thirds length of distal spine; tibia of leg I with 21 articles, tarsus I with 37 articles; leg IV basitibia with three pseudo-articles; leg IV basitibia trichobothrium bt situated in proximal third; leg IV distitibia with 16 trichobothria; sc and sf series each with five trichobothria; basal trichobothria bc and sbf situated closer to each other than to bf.

Etymology

The name is an adjective derived from the Latin ‘ ferrum ’, referring to the iron ore cave in which the type specimens were collected (Giupponi & Miranda 2016).

Natural history

This species is only found inside iron ore caves. It exhibits troglomorphic characters, such as pale coloration and the almost complete absence of eyes, and may be troglobitic.
