A new species of Cocinachernes (Pseudoscorpiones: Chernetidae) associated with mosses in Mexico

Pseudoscorpions can be found in different microhabitats, one of which is moss. In this paper, we report the first records of pseudoscorpions associated with mosses in Mexico. We found three species: Albiorix edentatus, Paratemnoides nidificator and a new species of the genus Cocinachernes which is described below as C. akalchesis sp. nov. The specimens were collected from moss of the genus Bryum. This new species has globose spermathecae with four tubes: two short and two long, with ocular spots in the carapace; trichobothrium distance between t and st is less than the distance of t from the fingertip, Femur L/B ranges from 2.4 to 2.9, tibia from 1.68 to 1.9, chela is 2.9 (without pedicel), and hand (without pedicel) ranges from 2.53 to 2.88; galea short and slightly robust, without divisions in males; anterior operculum with 36 setae long and acuminated, posterior operculum with 20 acuminated setae. This new species represents the second known species of Cocinacheres from Mexico.
