Abstract

Despite being the most diverse family of flies found in carcasses and corps in the Neotropical Region, Sarcophagidae is still underestimated in Peru. This research was developed in the Department of Piura, Northern Peru and we identify the flesh flies captured on two kinds of animal carcasses: dog and guinea pigs. As a result, a new record was documented for Peru: Blaesoxipha (Gigantotheca) plinthopyga (Wiedemann, 1830) and eight new records for the Department of Piura.

Highlights

Sarcophagidae is a family of flies, commonly called “flesh flies”, that are distributed globally, comprising 173 genera and more than 3,000 species (Pape et al, 2011)
Sarcophagids are the most diverse flies found in carcasses and corpses in the Neotropical region (Alves et al, 2014), studies on association of flesh flies and carcass decomposition are still rare
One of the limiting factors is the taxonomic difficulty presented by the group, whose specific identification is mainly based on features of the male terminalia complex (Santos, 2018)

Summary

Introduction

Sarcophagidae is a family of flies, commonly called “flesh flies”, that are distributed globally, comprising 173 genera and more than 3,000 species (Pape et al, 2011). The females are ovoviviparous multilarviparous, that is, they deposit many first instar larvae directly on the substrate (Meier et al, 1999). This habit of larviposition constitutes an adaptive advantage against other early colonizers flies as Calliphoridae or Muscidae (Barros et al, 2008). Sarcophagidae has great forensic importance because they are pioneering flies in colonizing human and animal carcasses, along with Calliphoridae and Muscidae (Oliveira-Costa & Mello-Patiu, 2004; Santos, 2018). The few records of Sarcophagidae associated with animal carcasses have been made mainly on pigs carcasses, as it is the most internationally accepted biomodel (Jagmahender & Sharma, 2008), since it
