Article Description

The morphology and ultrastructure of the sensilla ampullacea on the pedipalps of Solifugae (Arachnida) are described. There are several hundred sensilla per pedipalp, each innervated by one dendrite with 2 distal segments running to the tip of the peg without branching. The specific features of the cuticular part of the sensillum are a complicated apparatus at the base of the peg, a peg wall formed by a double epicuticular lattice, an extremely long neck, and a cuticular “goblet” around the cellular part of the organ. The cellular complex, consisting of sheath cells, enveloping cells, and a secretory cell, is described. The structural peculiarities of the sensillum are discussed and compared with other arthropod sensilla. The possession of 2 distal dendritic segments per proximal segment is suggested to be a common feature of what are thought to be the less-highly evolved arthropods. In arachnids, high density of microtubules in the distal dendritic segments seems to be a more common feature than in insects. Some specific features of the sensillum are proposed to be adaptations against water loss by evaporation. The structure of the sensilla ampullacea is compatible with both olfactoreception and thermo- and/or hygroreception.
