Diagnosis

Based on the original description, supplemented by observations of Quintero (1983), this species may be separated from other Charinus in Amazonia and northern South America by means of the following combination of characters: median eyes and median ocular tubercle absent; lateral eyes reduced; sternum with undivided platelets, not pairs; pedipalp femur with three dorsal spines and three or four ventral spines; pedipalp patella with three dorsal spines and large setiferous tubercle between spine I and distal margin, and two prominent setiferous tubercles, decreasing in size, proximal to spine III; pedipalp patella with two ventral spines; pedipalp tibia with two dorsal spines, distal spine very long, more than half length of tibia, proximal spine one-third length of distal spine; cheliceral claw with five or six teeth; pedipalp tarsus with two dorsal spines; tibia of leg I with 23 articles, and with 41 articles; leg IV basitibia with three articles ( Ravelo (1975), and also Quintero (1983), considered the distitibia to be part of the tibia, resulting in a count of four articles); leg IV distitibia trichobothrium bc situated closer to sbf than to bf; sc and sf series each with five trichobothria.

Natural history

Charinus tronchonii was the first species of the genus to be considered troglobitic in South America ( Ravelo 1975), due to the absence of median eyes.
