Scientists' warning to humanity on insect extinctions
Taxonomic revision and cladistic analysis of Avicularia Lamarck, 1818 (Araneae, Theraphosidae, Aviculariinae) with description of three new aviculariine genera
TLDR
Cladistic analyses using both equal and implied weights were carried out with a matrix of 46 taxa from seven theraphosid subfamilies, and 71 morphological and ecological characters suggesting Avicularia and Aviculariinae are monophyletic.
Revision of Cyriocosmus Simon, 1903, with notes on the genus Hapalopus Ausserer, 1875 (Araneae: Theraphosidae)
TLDR
The genus Cyriocosmus Simon, 1903 is revised based on most types and additional material from Argentina, Brazil, Colombia, Tobago Island and Venezuela, finding a single, totally resolved tree with the same topology.

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.
Two new species of Pamphobeteus Pocock 1901 (Araneae : Mygalomorphae : Theraphosidae) from Brazil, with a new type of stridulatory organ
TLDR
Two new species of Pamphobeteus Pocock 1901 are described from Brazil and a new type of stridulatory organ is described from legs III and IV of P. crassifemur sp.

TLDR
The tarantula genus Ephebopus Simon 1892 is reviewed and includes the type species, E. murinus, which occurs in northeastern South America where it is known only from Brazil, Guyana, Suriname, and French Guiana.
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.
