FEMALE INTERNAL REPRODUCTIVE-ORGANS, MODES OF SPERM TRANSFER, AND PHYLOGENY OF ASIAN EPILACHNINAE (COLEOPTERA, COCCINELLIDAE)

A total of 22 Indonesian and Japanese species of epilachnine ladybird beetles were divided into the following three groups on the basis of t he conditions of bursa copulatrix and spermatheca, and modes of sperm transfer. Group 1, 'Henosepilachna', being characterized by a spermath eca derived from the lateral side of a well developed bursa copulatrix and formation of a 'spermatophore' prior to ejaculation; group 2, Epi lachna admirabilis species-group and E. chapini group, by a spermathec a derived from terminal end of a well developed bursa copulatrix and l ack of spermatophore formation; and group 3, E. flavicollis group and E. fallax group, by a reduced bursa copulatrix with or without a termi nally positioned spermatheca and lack of spermatophore formation. It w as suggested that groups 2 and 3 are phylogenetically more closely rel ated to each other than they are to group 1.
