Sexually dimorphic tegumental gland openings in Laniatores (Arachnida, Opiliones), with new data on 23 species
Sexually dimorphic glands often release sexual pheromones both in vertebrates and invertebrates. Species of Laniatores (Arachnida, Opiliones) seem to depend on chemical communication but few studiesExpand

An ethological approach to a SEM survey on sensory structures and tegumental gland openings of two neotropical harvestmen (Arachnida, Opiliones, Gonyleptidae)
We studied the sensory structures and tegumental glands of two harvestmen species, Neosadocus sp. and Iporangaia pustulosa. We also provide field data of dietary items and data on the foragingExpand

Sexually dimorphic legs in a neotropical harvestman (Arachnida, Opiliones): Ornament or weapon?
The evolution of sexually dimorphic traits has been the focus of much theoretical work, but empirical approaches to this topic have not been equally prolific. Males of the neotropical familyExpand

Behavioral roles of the sexually dimorphic structures in the male harvestman, Phalangium opilio (Opiliones, Phalangiidae)
Abstract: In various animal species, male sexual dimorphic characters may be used during intrasexual contests as ornaments to attract females, or to hold them before, during, or after copulation. InExpand

A scanning electron microscopic survey of the cuticle in Cyphophthalmi (Arachnida, Opiliones) with the description of novel sensory and glandular structures
The cuticular surfaces of Cyphophthalmi (Opiliones) were studied in detail, covering a wide range of their taxonomic diversity. Previously unknown structures are described, including a sexuallyExpand

Breeding biology of the cavernicolous harvestman Goniosoma albiscriptum (Arachnida, Opiliones, Laniatores): sites of opposition, egg batches characteristics and subsocial behaviour
Summary We present field data on seasonality, mating behaviour, sites of oviposition, characteristics of egg batches, and parental care of a cavernicolous population of the Brazilian harvestmanExpand

Harvest-ironman: heavy armature, and not its defensive secretions, protects a harvestman against a spider
Natural selection has caused prey species to evolve distinct defensive mechanisms. One of such mechanisms was the evolution of noxious or distasteful chemicals, which have appeared independently in aExpand

Experimental demonstration of close‐range olfaction and contact chemoreception in the Brazilian harvestman, Iporangaia pustulosa
We studied the ability to detect food by close‐range olfaction and contact chemoreception in the harvestman Iporangaia pustulosa Mello‐Leitão (Opiliones: Laniatores: Gonyleptidae). We first testedExpand

Costs and benefits of freezing behaviour in the harvestman Eumesosoma roeweri (Arachnida, Opiliones)
Animals present an enormous variety of behavioural defensive mechanisms, which increase their survival, but often at a cost. Several animal taxa reduce their chances of being detected and/orExpand
