Variation of cleaning organ structures and setae of pedipalp tarsus in the family Phrynidae (Arachnida: Amblypygi)

The pedipalp tarsus of Amblypygi is used as a cleaning tool in grooming behavior and as a weapon in prey capture. The tarsus presents several structures with unknown functions that probably relate to both processes. The Amblypygi tarsus possesses a cleaning organ with two lines of projections and a...

520 |a The pedipalp tarsus of Amblypygi is used as a cleaning tool in grooming behavior and as a weapon in prey capture. The tarsus presents several structures with unknown functions that probably relate to both processes. The Amblypygi tarsus possesses a cleaning organ with two lines of projections and a group of setae distributed along the structure. We analyzed the morphological variation of the cleaning organ structures and the setae of the tarsus in species of the family Phrynidae using scanning electron microscopy (SEM). Additionally, we made histological sections to evaluate the sensory function of the structures. We found variation in the shape and size of the setae, projections and granular area of the cleaning organ; however, the observed differences do not allow for differentiation of taxonomic genera. The setae and projections of the cleaning organ have an internal structure similar to tip-pore sensilla. Externally, the setae are similar to the sensorial hairs in spiders and differ from the cleaning organ projections, which probably are modified setae. Mechanoreception function is evident in the setae, and is probable in projections of the cleaning organ; the evidence observed indicates that both structures may be considered as putative chemoreceptors.
