  New data on the distribution of Aguapanela arvi Perafán, Cifuentes & Estrada, 2015 in Colombia through collections and citizen science, with notes on the natural history (Araneae: Theraphosidae) Abstract This paper expands the known distribution of Aguapanela arvi Perafán, Cifuentes & Estrada, 2015 in Colombia by reporting its presence for the first time in the departments of Caldas, Quindío, and Risaralda. Additionally, new aspects of its natural history are documented, including parasitic interactions involving a parasitoid wasp and an arthropod-pathogenic fungus. These findings are based on field observations, specimens deposited in biological collections, and citizen science records.

The scorpions of the Estación de Biología Chamela, Jalisco, Mexico with the description of a new species of Mesomexovis (Scorpiones, Vaejovidae) and an identification key

Abstract

Mesomexovis Gonzalez-Santillan & Prendini, 2013 is a scorpion genus of the Vaejovidae family that comprises seven species, all endemic to Mexico. The present study describes a new species from Estación de Biología Chamela, Jalisco, related to M. occidentalis (Hoffmann, 1931), M. atenango (Francke & Gonzalez-Santillan, 2006), and M. subcristatus (Pocock, 1898). Mesomexovis caxcan sp. nov. differs from these species in several respects. Firstly, the carinae of the pedipalp chelae are vestigial. Secondly, the ventral lateral carinae of metasomal segments I–IV are granular, and the ventral submedian carinae of segments I–IV are costate to granular. A microstructural separation between the subex and the basal carina of the capsular area of the hemispermatophore is described for the first time. Mesomexovis caxcan sp. nov. represents the eighth species of the genus and the fifth reported in the Estación de Biología Chamela. The other scorpions identified in this location are Centruroides chamela Ponce-Saavedra & Francke, 2011, C. elegans (Thorell, 1876) (Buthidae), Konetontli chamelaensis (Williams, 1986), and Thorellius intrepidus (Thorell, 1876) (Vaejovidae).
