DE ARMAS, Luis F.  and  PALOMINO-CARDENAS, Andrea C.. New species of the genus Charinus (Amblypygi; Charinidae) from Cusco, Peru. Rev. peru biol. [online]. 2023, vol.30, n.2, e24115.  Epub June 28, 2023. ISSN 1727-9933.  http://dx.doi.org/10.15381/rpb.v30i2.24115.

A new species of the genus Charinus Simon, 1892 is described from Santa Teresa District (1436 -1511 m of altitude), La Convención, Cusco, Peru, being this the third Charinus species from this region and the fifth one for this South American country. Its general feature and female gonopods greatly resembles Charinus longitarsus Armas & Palomino-Cardenas, 2016, and C. yanatile Palomino-Cardenas & Armas, 2022, from Cusco, too; but it differs from them by having 16 instead of 14 trichobothria in the distitibia of leg IV; on the other hand, in C. longitarsus the leg I has 30 tarsomeres (43 in the new species); whereas C. yanatiles has larger median ocular tubercle and the first tarsomere of leg I is longer than tarsomeres 1+2 joined. Also, the description of the female gonopods of C. longitarsus is emended and a taxonomic key for the identification of the Peruvian species of Charinus is given.
