Harvestmen are a major arachnid order that has experienced a dramatic increase in
biological knowledge in the 21st century. The publication of the book Harvestmen: The …

For the first time a hypothesis of homology is proposed for the macrosetae which compose
the armature of the distal truncus penis of the Gonyleptoidea. Previous attempts to name …

Opiliones are one of the largest arachnid orders, with more than 6,500 species in 50
families. Many of these families have been erected or reorganized in the last few years since …

Gonyleptidae is the second most diverse harvestmen family and the most studied in terms of
morphology, behaviour, and ecology. Despite this, few phylogenetic studies have focused …

Gonyleptoidea, largely restricted to the Neotropics, constitutes the most diverse superfamily
of Opiliones and includes the largest and flashiest representatives of this arachnid order …

Secondary sexual traits increase male fitness, but may be maladaptive in females,
generating intralocus sexual conflict that is ameliorated through sexual dimorphism. Sexual …

The first cladistic analysis of the Tricommatinae is presented here based on a matrix with 88
terminals and 117 characters. The subfamily, hitherto with 28 genera and 53 species, is not …

Abstract The Brazilian Atlantic Forest has long been considered a global biodiversity
hotspot. In the last decade, the phylogeographic patterns of endemic taxa have been …

Benzoquinones are usually present in arthropod defence exudates. Here, we describe the
chemical profiles of 12 harvestman species belonging to the neotropical family …

Abiotic factors exert direct and indirect influences on behavioral, morphological, and life-
history traits. Because some of these traits are related to reproduction, there is a causal link …
