Abstract Since its original description, the theraphosid spider genus Crassicrus Reichling & West, 1996 has not been revised and no new species have been described. While reviewing material deposited in the Mexican National Collection of Arachnids (National Autonomous University of Mexico, Mexico City) and the American Museum of Natural History (New York, USA), we encountered specimens corresponding to four new species of Crassicrus from Mexico. In this revision, we include a redescription of… 
Revised taxonomic status of some Mexican and Central American tarantulas (Araneae: Theraphosidae), with transfers from Aphonopelma Pocock, 1901, and a new genus from the Pacific lowlands of Nicaragua and Costa Rica
TLDR
The type material of several Central American tarantulas were re-examined within a broader revision involving the defunct genus Eurypelma Koch, 1850 and the poorly defined Aphonopelma Pocock, 1901, to create the new monotypic genus Sandinista gen. nov.
Species conservation profiles of tarantula spiders (Araneae, Theraphosidae) listed on CITES
TLDR
To assess the 21 taxonomically valid spider species listed on CITES according to the IUCN criteria, study the general patterns and trends and advise on possible future conservation actions critical for the survival of endangered species, it is proposed to prioritise and support research on the population trends and distribution, as well as on the impact of land use and habitat degradation.

Revalidation of Pterinopelma Pocock 1901 with description of a new species and the female of Pterinopelma vitiosum (Keyserling 1891) (Araneae: Theraphosidae: Theraphosinae)
TLDR
The preferred tree shows that Pterinopelma is a monophyletic genus sister to the clade Lasiodora (Vitalius + Nhandu) and the presence of denticles on the prolateral inferior male palpal bulb keel is a synapomorphy of the genus.
Morphology, evolution and usage of urticating setae by tarantulas (Araneae: Theraphosidae)
TLDR
It is proposed that spiders use the various types of urticating setae differently and according to their different targets: type I setae, when incorporated either into the molting web or eggsac, is more effective against invertebrates than type III, which seems to be used mainly against vertebrate predators.
