We redescribe and illustrate the male of Thrixopelma ockerti Schmidt, 1994 presenting the first analysis of keels on the palpal bulb. Additionally, a new species Thrixopelma kimraykawsaki sp. nov. is described and illustrated from Peru, along with data on its natural history. This new species is known from Abancay, department of Apurimac, can be di...
A cladistics analysis of the high-altitude tarantulas of the genus Hapalotremus was carried out for the first time with a matrix of 21 taxa and 69 morphological characters using both equal and implied weights. Two consistent topologies were obtained with a concavity = 10.541, resulting from a sensitivity analysis. Both cladograms suggest Hapalotrem...
ABSTRACT
This work aims to describe a new species of Thrixopelma Schmidt, 1994 from southcentral Peru in the Department of Cusco. Thrixopelma choquequirao sp. nov. can be easily distinguished from congeneric species by the low number of labial cuspules, a very long palpal tibia, morphology of the male palpal bulb and female spermathecae. Currently...
Chinchaysuyu gen. nov. is described as a new monotypic Theraphosidae genus from northern Peru, with distinct genitalic morphology. Males of Chinchaysuyu gen. nov. differ from all known species by having a palpal bulb organ with many conspicuous keels extending towards the subtegulum. Females differ by having two pairs of short and hyper-sclerotized...
A new species of Linothele Karsch, 1879 from southern Peru is described and illustrated, L. mu-bii sp. nov. The new species can be distinguished from other species of the genus by scopulation in combination with the morphology of copulatory organs.
For several decades, Troglotayosicus Loureno, 1981, remained an enigmatic, monotypic scorpion genus believed to be troglobitic. The discovery and description in recent years of several endogean species of the genus, inhabiting the leaf litter of tropical rainforests in Colombia and Ecuador, advanced knowledge about these scorpions. The known distri...

Human activities increasingly result in disturbance of wild animal populations. Behavioral responses vary according to the type, duration, frequency and intensity of disturbance. Exposure to disturbance, for example, arising from ecotourism, may promote tolerance of humans and drive a decrease in vigilance and avoidance behaviors, whereas disturban...

Aim
One of the planet's most imposing geomorphological features, the Andes, played an important role in the evolution of South America's flora and fauna. The bothriurid scorpion genus Brachistosternus Pocock, 1893 comprises more than 40 species with high diversity and endemism in the Andes. The present contribution investigates the biogeographical...
Autotomy, the voluntary shedding or detachment of a body part at a determined cleavage plane, is a common anti-predation defense mechanism in several animal taxa, including ar-thropods. Among arachnids, autotomy has been observed in harvestmen, mites, and spi-ders, always involving the loss of legs. Autotomy of the opisthosoma (abdomen) was recentl...
Slow motion (10% of real time) sequence of the moment of metasomal autotomy in a male Ananteris solimariae Botero-Trujillo & Flórez, 2011 scorpion, illustrating lateral twisting motion of the metasomal segments anterior to the cleavage plane, immediately preceding detachment of the posterior metasomal segments. http://journals.plos.org/plosone/arti...
