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 in color; median eyes and median ocular tubercle absent; lateral eyes well developed; small, rounded, markedly sclerotized tetra- and pentasternum; cushion-like female gonopod with lateral projections directed posteriorly, covering opening of internal seminal receptacles (atrium); pedipalp femur with two dorsal spines and three ventral spines; pedipalp tarsus with two spines, proximal spine small, ca one quarter length of distal spine; tibia of leg I with 21 articles, tarsus I with 37 articles; leg IV basitibia with two pseudo-articles; trichobothrium bt situated in proximal third of distitibia; leg IV distitibia with 16 trichobothria; trichobothrium bc situated closer to sbf than to bf.
Charinus bichuetteae is one of ten species of Charinus in Amazonia and northern South America in which the basitibia of leg IV consists of two pseudo-articles; the others are C. bonaldoi, C. brescoviti, C. bromeliaea, C. carvalhoi sp. nov., C. camachoi, C. pardillalensis, C. platnicki, C. quinteroi and C. ricardoi. Charinus bichuetteae differs from C. bromeliaea and C. carvalhoi sp. nov. in the cushionlike gonopods, which are sucker-like in C. bromeliaea and in C. carvalhoi sp. nov. The absence of median eyes and ocular tubercle differentiates C. bichuetteae from C. brescoviti and C. bromeliaea. Seven of these species lack median eyes and median ocular tubercle, and can be differentiated from C. bichuetteae by the number of teeth on the cheliceral claw and the number of spines on the pedipalp femur.
Etymology
