Tarantula urticating setae are modified setae located on the abdomen or pedipalps, which represent an effective defensive mechanism against vertebrate or invertebrate predators and intruders. They are also useful taxonomic tools as morphological characters facilitating the classification of New World theraphosid spiders. In the present study, the morphology of urticating setae was studied on 144 taxa of New World theraphosids, including ontogenetic stages in chosen species, except for species… 
URTICATING SETAE IN URUGUAYAN TARANTULAS: ACTIVE OR PASSIVE DEFENSE?
TLDR
Significant differences were found between males and females of all sampled species, with females showing a predominance of types I (except subtype Ic) or IV setae over other types or subtypes, suggesting these type of US takes part in passive defense.
A new species and two new genera of theraphosine from Peru (Araneae: Theraphosidae)
TLDR
Two new theraphosine genera and one new species are described from Peru, based on material from the collections in the Natural History Museum, London, and the female of A. picta is redescribed, with the female described for the first time.
Phylogenomic analyses reveal a Gondwanan origin and repeated out of India colonizations into Asia by tarantulas (Araneae: Theraphosidae)
TLDR
It is determined that their current distributions are attributable to a combination of Gondwanan vicariance, continental rafting, and geographic radiation, which provides support for a dual colonization of Asia by two different tarantula lineages that occur at least 20 million years apart.
Stabilizing a chaotic taxonomy: redescription and redefinition of the genera Lasiodorides Schmidt & Bischoff, 1997 and Thrixopelma Schmidt, 1994 (Araneae: Theraphosidae)
TLDR
It is argued that future designation of exuviae as type specimens of novel theraphosid spiders should be considered an unacceptable practice in arachnology.
The biology and evolution of spider venoms.
TLDR
The mechanisms that drive spider venom evolution are summarized and the need for genome-based studies to reconstruct the evolutionary history and physiological networks of spider venom compounds with more certainty is highlighted.
Edible arachnids and myriapods worldwide – updated list, nutritional profile and food hygiene implications
Like insects, arachnids (spiders, scorpions, mites and ticks) and myriapods (millipedes and centipedes) also have a history of traditional consumption, either as foodstuff or medicine. In this revi...

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.
Kankuamo, a new theraphosid genus from Colombia (Araneae, Mygalomorphae), with a new type of urticating setae and divergent male genitalia
TLDR
It is hypothesized that these setae are the first in Theraphosinae subfamily whose release mechanism is by direct contact, and their remarkable characteristics, morphological affinities and cladistic relationship are analyzed.
Taxonomic revision of Hemirrhagus Simon, 1903 (Araneae: Theraphosidae, Theraphosinae), with description of five new species from Mexico
TLDR
The theraphosine genus Hemirrhagus is revised based on the examination of the type specimens and additional material collected in Mexico and different types of stridulatory organs are described for the first time for the genus.
Aguapanela, a new tarantula genus from the Colombian Andes (Araneae, Theraphosidae).
TLDR
A new monotypic genus of Theraphosidae is described from Colombia with only the type species Aguapanela arvi Perafán, Cifuentes & Estrada sp.
THE OCCURRENCE OF ABDOMINAL URTICATING HAIRS DURING DEVELOPMENT IN THERAPHOSINAE (ARANEAE, THERAPHOSIDAE): PHYLOGENETIC IMPLICATIONS
TLDR
Sexual dimorphism in the occurrence of urticating hair types is analyzed and a hypothetical explanation is proposed for the dimorfismo sexual encontrado in estos pelos for algunas especies of terafósidas.
Redescription of the holotypes of Mygalarachnae Ausserer 1871 and Harpaxictis Simon (1982) (Araneae:Theraphosidae) with rebuttal of their synonymy with "Sericopelma" Ausserer 1875
TLDR
It is argued that Mygalarachnae and Harpaxictis should be removed from their current synonymy with Sericopelma Ausserer 1875 and restored as a valid genus.
A New Species of North American Tarantula, Aphonopelma paloma (Araneae, Mygalomorphae, Theraphosidae)
Aphonopelma paloma new species, is distinguished from all other North American tarantula s by its unusually small size and presence of setae partially or completely dividing the scopula of tarsus IV
The Andean tarantulas Euathlus Ausserer, 1875, Paraphysa Simon, 1892 and Phrixotrichus Simon, 1889 (Araneae: Theraphosidae): phylogenetic analysis, genera redefinition and new species descriptions
TLDR
The Chilean tarantula genera Euathlus and Paraphysa are revised, and some of their constituent species are transferred, and Phrixotrichus is resurrected.
MALE PALPAL BULBS AND HOMOLOGOUS FEATURES IN THERAPHOSINAE (ARANEAE, THERAPHOSIDAE)
Abstract A first attempt to homologize male palpal bulb structures of theraphosine spiders is made, with the aim of providing systematic characters. The morphology and distribution of palpal bulb
