Proshapalopus marimbai, a new tarantula species (Mygalomorphae, Theraphosidae) and first genus record from Colombia

Carlos Perafán, Dayana Valencia-Cuéllar ,2018

A new species of Proshapalopus Mello-Leit~ao, 1923, distributed in the Southwest Colombia in the Choco Region, is described. A morphological cladistic analysis based on the previous matrix of a Theraphosinae group confirmed the inclusion of this species within Proshapalopus. The new species, Proshapalopus marimbai n. sp., can be distinguished from other species of the genus mainly by the reduced number of labial cuspules, around 40; in contrast the other species having over 100. Males can be distinguished by the thickened femur III, presence of intermediate urticating setae type I-III only, palpal bulb with a considerably long prolateral inferior keel (from ventral median depression to embolus apex) and the accessory keel pronounced distally. Females can be distinguished for lacking urticating setae type III and the non-incrassated tibia IV. This discovery constitutes the fourth species described for Proshapalopus and the first record for Colombia, expanding the geographical distribution of the genus, until now known for Brazil only. Other aspects of distribution and the phylogenetic relationship of the new species are also discussed here.

The genus Holothele Karsch, 1879: the identity of the type species (Mygalomorphae, Theraphosidae)

José Paulo Leite Guadanucci, Carlos Perafán, Dayana Valencia-Cuéllar ,2017

The genus Holothele Karsch, 1879 has a confusing taxonomic history, mainly due to a imprecise and outdated generic diagnosis, perpetuated since its original description. In this work, we propose a new diagnosis for the genus, redescribe the type species Holothele recta Karsch, 1879 and propose a few taxonomic changes. Holothele longipes is here considered as a senior synonym of Holothele recta Karsch, 1879, Stichoplastus sanguiniceps F. O. P.-Cambridge, 1898, Dryptopelmides rondoni Lucas & Bücherl, 1972, Dryptopelmides ludwigi Strand, 1907. We also provide updated geographic distribution records for Holothele longipes and propose the revalidation of Scopelobates Simon, 1903.
