Assessing information about prey before attacking is crucial for predators. Whip spiders (Arachnida, Amblypygi) are predatory arachnids that prey mainly on arthropods and whose first pair of legs concentrates many sensory structures. Nonetheless, these aspects of amblypygid biology have been mostly studied in a few species of Phrynidae and basic information about predatory behavior and sensory morphology remain scarce for other families. In this study, we described the sensory morphology of the antenniform leg and the predatory behavior of Charinus asturius Pinto-da-Rocha, Machado and Weygoldt, 2002, a representative of the family Charinidae. We report the presence of most sensilla types described in the better studied Phrynidae and highlight novel aspects such as the morphology of the tarsal organ and the reduced number of rod sensilla. Our behavioral results underscore the importance of antenniform legs in the predatory behavior of C. asturius. Finally, we suggest new avenues to advance the knowledge about the importance of antenniform legs for capturing living prey. (AU) | |
