The Musculoskeletal System of Male Genitalia in Curetis bulis Westwood, 1851 (Lepidoptera, Lycaenidae: Curetinae) and Paralaxita damajanti (C. Felder et R. Felder, 1860) (Lepidoptera, Riodinidae: Nemeobiinae)1

摘要

The muscles of the male genitalia were studied for the first time in two species endemic to the Oriental zoogeographical region, namely Curetis bulls from the subfamily Curetinae (Lycaenidae) and Paralaxita damajanti from the tribe Abisarini (Riodinidae). Both taxa possess a common plan of musculature reflected in the positions of muscles ml, m2(I0), m5(7), m7(6), m21, and m28. Two new autapomorphies of Curetis bulls were discovered: the splitting of m4 into two muscles and a shift of the attachmentsite of one of these muscles onto the dorsal area of the anellus. Apomorphic differences in the position of the genital muscles were found between Paralaxita damajanti and the previously studied Polycaena tamerlana from the family Riodinidae. A new synapomorphy between the latter two species, namely splitting of the aedeagus protractors m6(5), was also found.
