Abstract

ALVAREZ, Fernando; TORRES, Eduardo  and  VILLALOBOS, José Luis. New species of crayfish of the genus Procambarus, and notes on Procambarus pilosimanus (Decapoda: Cambaridae) from Chiapas, Mexico. Rev. Mex. Biodiv. [online]. 2021, vol.92, e923833.  Epub May 09, 2022. ISSN 2007-8706.  https://doi.org/10.22201/ib.20078706e.2021.92.3833.

A new species of crayfish is described from the Cave of Sótano de La Lucha, in the border between the Mexican states of Chiapas and Oaxaca. The new species is completely adapted to the cave environment with reduced eyes lacking cornea and visual pigments, an almost unpigmented body and elongated appendages. We also report on crayfish populations from the “Lagunas de Montebello” area, which fit well the description of Procambarus pilosimanus (Ortmann, 1906), a heretofore problematic species in southern Mexico.

Keywords : Stygobitic crayfish; Sótano de La Lucha; Lagunas de Montebello; Chiapas.
