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: median and lateral eyes present; median ocular tubercle and lateral eyes markedly reduced; small, rounded tetra- and pentasternum; reduced tritosternum, slightly surpassing base of pedipalp coxae; cushion-like female gonopod with lateral projections directed posteriorly, covering openings of internal seminal receptacles (atrium); male gonopods with long, curved, wrinkled medial lobes ( Fig. 8E–F ); lateral lobes fimbriate ( Fig. 8E–F, H ); dorsal lobe surpassing length of other lobes and with elevated scales ( Fig. 8E, G ); marked secondary sexual dimorphism evident, males with longer pedipalps, ca twice as long as female pedipalps; pedipalp femur with four dorsal spines; two dorsal spines on pedipalp tarsus, small basal spine, one-quarter length of distal spine; tibia of leg I with 23 articles, tarsus I with 42 articles; leg IV basitibia with three pseudo-articles; leg IV basitibia trichobothrium bt situated in proximal third; leg IV distitibia sc and sf series each with five trichobothria; leg IV distitibia trichobothrium bf equidistant between bc and sbf; tegument pale yellow.

This is among the few Amazonian species in which the median eyes and median ocular tubercle are present.

Etymology

Noun in apposition, taken from the Caraja mountain range where the species was collected, and from the indigenous people known as the karajas ( Giupponi & Miranda 2016).
