Palp sensory structures in adult caddisflies of the suborder Annulipalpia (Trichoptera): a scanning electron microscopy study
Number: 487, Pages: 1 - 20
Sensory structures and their patterns are investigated by scanning electron microscopy in 38 species representing ten families of the suborder Annulipalpia (Trichoptera). Palp sensilla comprise seven types: long trichoid, chaetoid, campaniform, mushroom-like pseudoplacoid, petaloid, thick basiconic, and thin basiconic sensilla. Comparative analysis suggests the presence of family-specific patterns of the palp sensory surfaces. Palp sensilla and their sensory patterns persist in the instances of partial palp reduction. Considerations on the evolution trends, functionality, and taxonomic importance of palp sensory structures are provided.
