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

The genus Holothele Karsch, 1879 has a confusing taxonomic history, mainly due to a imprecise and outdated generic diagnosis, perpetuated since its original description.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.
