Sarcophagidae is a worldwide distributed flesh-fly family that encompasses about 3000 named species (Pape et al., 2011), being the second most species-rich family within the superfamily Oestroidea, and is usually classified into three subfamilies: Miltogramminae, Paramacronychiinae, and Sarcophaginae (Pape, 1996; Pape et al., 2011). The latter subfamily, with about 2300 species in 46 genera (Buenaventura & Pape, 2018), has its highest richness in the Neotropical Region and is generally more diverse in life habits and morphology of the male terminalia than the other two subfamilies (Buenaventura et al., 2018).

The study of the sarcophagid fauna in Colombia has been focused on flies collected near the main cities attracted with carrion (Wolff et al., 2001; Pérez et al., 2005; Martinez et al., 2007; Buenaventura et al., 2009; Barrios & Wolff, 2011; Ramírez-Mora et al., 2012; Amat et al., 2013; Yepes-Gaurisas et al., 2013; Ramos-Pastrana et al., 2014; Valverde Castro et al., 2017). To date, there are 109 recorded Sarcophagidae species for Colombia (Pape, 1996; Pape et al., 2004; Ramírez-Mora et al., 2012; Buenaventura & Pape, 2013; Yepes-Gaurisas et al., 2013; Mello-Patiu, 2016; Souza & Buenaventura, 2016; Valverde-Castro et al., 2017, Souza et al., 2020), of which 103 belong to the subfamily Sarcophaginae. In this study, we aimed to contribute to the knowledge of the Sarcophaginae species recorded for the first time in localities from Colombia and to extend the geographical distribution of previously known species.

A total of 485 male specimens were examined from 31 localities (Fig. 1), collection data are summarized in Table I.

The material is deposited at the Colección Entomológica Tecnológico de Antioquia (CETdeA, number 204 in the Colombian National Record). Specimens were attracted using Van Someren Rydon traps baited with decomposing fish and chicken, traps were left in the field between 12-24 hrs. Male specimens were examined and identified using the reference collection previously identified by Dr. Eliana Buenaventura hosted at CETdeA, and the following taxonomic keys, descriptions, and redescriptions: Guimarães (2004), Pape & Mello-Patiu (2006), Carvalho & Mello-Patiu (2008), Vairo et al. (2011), Carvalho Filho & Esposito (2012), Buenaventura & Pape (2013), Vairo et al. (2014), Souza et al. (2020). Previous distributional records at country level for the Neotropical Region were obtained from Pape et al. (2004), Ramírez-Mora et al. (2012), Mello-Patiu (2016), Valverde-Castro et al. (2017), Dufek et al. (2020), and the references used for the taxonomic identification.

As a result, 22 species of Sarcophaginae were identified, six of which are recorded for the first time for Colombia: Argoravinia catiae Carvalho Filho & Esposito, 2012, Oxysarcodexia adunca Lopes, 1975, Oxysarcodexia carvalhoi Lopes, 1946, Oxysarcodexia eberti Lopes & Tibana, 1987, Peckia .Euboettcheria. epimelia (Lopes, 1938), and Peckia (Sarcodexia) chirotheca (Hall, 1933). The distribution of 16 species already known from Colombia is also updated, with new records for the departments of Amazonas, Antioquia, Chocó, Magdalena, and Meta (Table II).

This study provides 22 new geographic records of Sarcophaginae in Colombia, South America, including species recorded for the first time for the country, and advances towards the knowledge of flesh fly diversity from Colombia. In particular, it increases the knowledge of the sarcophagid fauna in unexplored regions far from large urban centers such as Chocó and Meta departments. As a result, the number of known species of Colombian Sarcophaginae increased to 109. The most diverse genera registered in the country were Oxysarcodexia (31 species) and Peckia (27 species). These genera are common in the Neotropical Region and are represented by a large number of species.

Colombia is a country having various geographical regions and climates with diverse environments. Therefore, the actual number of sarcophagid species should be substantially higher than the one mentioned here.
