Parepalpus

Parepalpus species can be distinguished from related tachinid genera by characters of the male terminalia, particularly the shape and structure of the surstyli and cerci. The genus name refers to the reduced or modified palpi (mouthpart structures). Accurate identification to species level requires examination of genitalic morphology and reference to original species descriptions.

The genus occurs in the Americas. Parepalpus constans has been recorded from the United States and Canada. Parepalpus flavidus is known from the western United States. Parepalpus auroanalis, Parepalpus discors, Parepalpus labeosus, and Parepalpus similis have been recorded from various Neotropical regions including Mexico, Central America, and South America.

As tachinid flies, Parepalpus species function as parasitoids, though specific host records are not documented in available literature. The family Tachinidae is ecologically significant as regulators of other insect populations.

• Tachinini (tribe)Other genera within Tachinini share general body plan and require genitalic examination for definitive separation; Parepalpus is distinguished by palpus structure and male terminalia morphology.
