Title: Chemical and behavioral defenses of the neotropical harvestman Camarana flavipalpi (Arachnida : Opiliones)
Author: Machado, G
Pomini, AM
Abstract: The defensive secretion of the harvestman Camarana flavipalpi (Gonyleptidae) was chemically characterized, revealing the presence of a single, highly volatile component (2-methyl-5-ethyl-phenol). Individuals do not frequently use chemical defenses and rely mainly on thanatosis as defense. Two types of emission of secretions were recorded: a globule at the gland opening without liquid displacement and liquid displacement along the lateral margins of the dorsal scute with accumulation of fluid at the later-oposterior area of the body. The anterior opening of the ozopore is covered by an integumentary dome that faces the laterodorsal area of the scute. The lateral channel is well defined near the opening of the ozopore and along the lateral margin of the dorsal scute as rows of small granules. The ozopore morphology of C. flavipalpi is similar to closely related species and simplified when compared with other species that promptly release chemical secretions. Published by Elsevier Ltd.
