Schismatothelinae spiders (Araneae, Mygalomorphae, Theraphosidae) from Colombia: four new species and an approach to their diversity 

Abstract: The spider subfamily Schismatothelinae from Colombia is revised. One new species of Euthycaelus Simon 1889 and three new species of Schismatothele Karsch 1879 are named, as well as new geographical records provided. E. guane sp. nov. from Santander, S. hacaritama sp. nov. from Norte de Santander, S. olsoni sp. nov. from Norte de Santander and Táchira (Venezuela), and S. weinmanni sp. nov. from Cundinamarca are herein described, diagnosed and illustrated. Schismatothele is newly recorded from Colombia. Morpholo… Show more

“…Males of Schismatothele can be recognized by the combination of the following characters: palpal tibia swollen (except S. quimbaya sp. nov.;, with several thick spines on the apical third in one row, arranged in one or two groups (38)(39)(46)(47)(72)(73) (Guadanucci & Weinmann 2014;Valencia-Cuéllar et al 2019) or in a single linear group (80)(81); palpal bulb with subtegulum large and totally fused with tegulum; tegulum rounded at the base (Guadanucci 2020); embolus short with an paraembolic apophysis below, except in S. caeri sp. nov., S. hacaritama and S. quimbaya, which has an apical keel instead (Figs 23-26, 59-62) (Valencia-Cuéllar 2019).…”

“…nov., S. hacaritama and S. quimbaya, which has an apical keel instead (Figs 23-26, 59-62) (Valencia-Cuéllar 2019). Females can be recognized by the spermathecae bulky and heavily sclerotized, except in S. weinmanni, which has the ventral receptacle weakly sclerotized with four receptacles divided in dorsal and ventral portions clearly distinguishable (Guadanucci & Weinmann 2014;Valencia-Cuéllar et al 2019).…”

“…This species constitutes the northernmost and westernmost record of the genus and subfamily for the country. Previously, the genus had a characteristic cis-Andean distribution over the Eastern Cordillera of Colombia and the Cordillera de Mérida in Venezuela ( Valencia-Cuéllar et al 2019 ). The geographic range of the genus Euthycaelus was recently extended with the publication of E. quinteroi from Panama, which is distributed in the same biogeographical region as E. cunampia sp.…”

“…Despite the great potential that Colombia has to become a worldwide reference on Mygalomorphae diversity, due to its geographical location and its enormous variety of ecosystems, only 34 of the 50 species described for the country are known by both sexes, and most of them are distributed in the Andean region ( Perafán 2017 ; WSC 2023). This scenario highlights the need to conduct studies that complement the taxonomic gaps and the scarce information that exists in other natural regions that have been little explored ( Cifuentes et al 2016 ; Perafán 2017 ; Perafán and Valencia-Cuellar 2018 ; Valencia-Cuellar et al 2019 ). The taxonomic novelties presented in this paper are part of the results obtained from a biological expedition carried out in the Jardín Botánico del Pacífico ( JBP ), focused on Mygalomorphae spiders.…”
