REPRODUCTIVE BIOLOGY OF URUGUAYAN THERAPHOSIDS (ARANEAE, MYGALOMORPHAE)
TLDR
The lengthy and costly sperm induction, the widespread display by body vibrations of courting males, multiple mating strategies of both sexes and the absence of sexual cannibalism are considered.

Ecology and behaviour of the ‘road tarantulas’ Eupalaestrus weijenberghi and Acanthoscurria suina (Araneae, Theraphosidae) from Uruguay
TLDR
Tarantulas showed spatial co‐occurrence and temporal coexistence with the beetle Diloboderus abderus, an important pest of grasslands, and polyphagous tarantulas seem to be potential agents for the biological control of beetle pests.

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.

Silk production from tarantula feet questioned
TLDR
It is shown that when the spinnerets are experimentally sealed, the zebra tarantula cannot secrete silk or similar threads, disagreeing with previous reports by Gorb et al..

Sexual dimorphism in chelicerae, forelegs and palpal traits in two burrowing wolf spiders (Araneae: Lycosidae) with sex-role reversal
TLDR
The occurrence of differences in morphological traits related to sex roles in both Allocosa species and the results with two non-burrowing wolf spiders with typical sex roles are explored.

Ami, a new Theraphosid genus from Central and South America, with the description of six new species (Araneae: Mygalomorphae)
TLDR
Females of Ami differ further from those of other theraphosid genera by their highly characteristic spermathecae: paired ventral receptacles attached to an almost discrete, semicircular, sclerotized back-plate.

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.

TLDR
The only species Iracema cabocla, from the Amazonic state of Roraima, Brazil, is described and the cladistic relationships of this genus within the Theraphosinae are analyzed.

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.
