Sexually dimorphic tegumental gland openings in Laniatores (Arachnida, Opiliones), with new data on 23 species
This study reviews the literature for the Phalangida and presents new data for 23 species of Laniatores, finding previously undescribed sexually dimorphic glandular openings on the femur, patella, metatarsus, and tarsus of legs I and metatarsu of legs III and IV.
An ethological approach to a SEM survey on sensory structures and tegumental gland openings of two neotropical harvestmen (Arachnida, Opiliones, Gonyleptidae)
This work describes five new tegumental glands, one sexually dimorphic in the metatarsus IV of I. pustulosa males and two that are rubbed against the substrate while walking, present in both species, the first morphological evidence that harvestmen might leave chemical marks on the substrate.
Sensory biology of Phalangida harvestmen (Arachnida, Opiliones): a review, with new morphological data on 18 species

Sexually dimorphic legs in a neotropical harvestman (Arachnida, Opiliones): Ornament or weapon?
Experimental demonstration of close‐range olfaction and contact chemoreception in the Brazilian harvestman, Iporangaia pustulosa
The results suggest that I. pustulosa is capable of detecting food only by its chemical properties; food with weak odor may not be detected by close‐range olfaction; and legs I and II are important for food detection but, before ingestion, legs I are used to examine potential food items.
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, including a sexually dimorphic row of spines and glandular openings on leg I of Fangensis cavernarum.
Behavioral roles of the sexually dimorphic structures in the male harvestman, Phalangium opilio (Opiliones, Phalangiidae)
The data show that the cheliceral horns and the longer pedipalps of the male seem to play an important role, during both intersexual and intrasexual encountering.
Neotropical harvestmen (Arachnida, Opiliones) use sexually dimorphic glands to spread chemicals in the environment.
