Joseph Villeneuve had a remarkable knowledge throughout the taxa of the Tachinidae family-group,
and he described a large number of flesh fly taxa. Standing, as it were, directly on the shoulders of
Louis Pandellé, Villeneuve utilised the diagnostic powers in the study of the male terminalia,
and the illustration of the phallus of Sarcophaga subvicina given in his very first paper on
Sarcophagidae is probably the first ever to be provided for any flesh fly as a means of identification
(already De Geer  provided an illustration of the male phallic complex, but here only as
morphological documentation). However, Villeneuve never took full advantage of the study of
male terminalia, and his illustrations are few and somewhat sketchy.
