Abstract:

"Male genital structures and muscles of bombycoid moths have repeatedly been misidentified in the literature. Furthermore, the genital structures of some bombycoid families, such as the poorly known Australo-New Guinean Anthelidae, have essentially remained unstudied. Based on comparative morphology, this study details the principal arrangements of male genital sclerites and muscles in all bombycoid families, with particular focus on basic structures and their modifications in Anthelidae. Emphasis is placed on the homology of and fusions between these structures and their function, providing a basis for the interpretation of modifications in future phylogenetic and taxonomic studies. This includes the unique fusion of gnathos and valvae in several bombycoid families, the arrangement and extent of the fused tegumen and vinculum, as well as the homology of the ‘‘transtilla’’. Further, a modification of the valve adductor muscle (the segment IX sternum to valva muscle, m4) widely regarded as a synapomorphy of Bombycoidea is demonstrated to be non-existent, as is the presumed presence of the valve abductor muscle (the segment IX tergum to valva muscle, m2) in Saturniidae."
