Abstract
The family of mygalomorph spiders Paratropididae Simon, 1889 is here reported for the first time for Colombia, where it is represented by three genera (Anisaspis, Paratropis, Stormtropisgen. n.) and eight species. One genus, Stormtropis, and six species constitute new taxa that are here diagnosed, described and illustrated. The geographical distribution of Paratropispapilligera FO Pickard-Cambridge, 1896 and Paratropiselicioi Dupérré, 2015 are also redescribed and expanded on the basis of new material examined. The diagnosis of the subfamily Paratropidinae, Paratropis Simon, 1889 and Anisaspis Simon, 1892 are emended including the variations of the new species. Likewise, a geographic distribution map for the entire family and a taxonomic key for the males of Paratropidinae are included. Other biogeographic, morphological, and taxonomic aspects are discussed.
Highlights
Paratropididae Simon, 1889, known as bald legged spiders, is one of the most enigmatic groups of Mygalomorphae due to its cryptic habits, singular biology, and controversial phylogenetic position
The first Paratropididae from Colombia: new genus, species and records lomorph spiders from Colombia including field and collection data produced some important results for Paratropididae, which we present here: a new genus, Stormtropis gen. n., with four new species; a new species of Anisaspis, which represent the first male description for the genus and the first record for South America; one new species of Paratropis; and a new record of P. papilligera FO Pickard-Cambridge, 1896 and P. elicioi Duperré, 2015
De Mello-Leitão (1941) recorded Paratropis scruposa Simon, 1889 for Cúcuta (Colombia): this determination has not been included in the World Spider Catalog (2018); possibly this is a wrong identification, since the type locality of this species is in Peru
Summary
Paratropididae Simon, 1889, known as bald legged spiders, is one of the most enigmatic groups of Mygalomorphae due to its cryptic habits, singular biology, and controversial phylogenetic position. Paratropidids constitute a small family of spiders, currently comprising four genera and eleven species, distributed in Mexico, Central America, Lesser Antilles, and northern South America except Colombia Paratropidids are characterized by the soil encrusted or scaly cuticle, weakly or ascopulate tarsi I and II and absence of scopulae elsewhere, maxillary lobes elongated, and the presence of labial cuspules usually arranged in an anterior rectangular group (Raven 1985). Paratropidinae includes three genera, Paratropis Simon, 1889 with six species, distributed in Mexico, Venezuela, Brazil and Peru; Anisaspis Simon, 1892 with one species from Saint Vincent island; and Anisaspoides FO Pickard-Cambridge, 1896 with one species from Brazil. We discuss the geographic distribution and diversity of paratropidids as well as some biological and morphological characteristics
