A Gynandromorph in Parasarcophaga harpax (Diptera, Sarcophagidae), with Special Reference to "Hypopygium Circumversum" of the Calyptrate Postabdomen

概要

A gynandromorphic individual of Parasarcophaga harpax showing female head and male genital abnormalities has been reared from a pupa of the pine-moth, Dendrolimus spectabilis. The abnormal postabdomen is suggestive for the condition of hypopygium circumversum in the Sarcophagid flies and the related Calyptrate groups. The position of fifth to ninth sternites were easily traced and indicated the 360° rotation of sarcophagine hypopygium. This also supports the CRAMPTON'S theory that the first genital segment is composed of sternites 7 and 8 which might be fused with each other. The absence of tergite 6 may be considered to be a derived condition from that of the subfamilies Macronychiinae and Miltogrammatinae.
