    ABSTRACT: Peckia is the most species-rich necrophagous genus among the Neotropical sarcophagids, encompassing 67 species distributed in 5 subgenera. Recent phylogenetic studies have challenged the monophyly of this genus with regard to species of the genera Peckiamyia, Titanogrypa, and Villegasia, and the genera Engelimyia, Helicobia, Retrocitomyia, and Sarcophaga. These genera have variously been hypothesized as sister groups to Peckia, or genera closely related to it. We applied cladistic methods using both molecular and morphological data to study phylogenetic relationships of these mostly necrophagous taxa. All currently recognized species of Peckia were included in our analysis. Based on 116 morphological characters and sequences of five gene fragments, we corroborate the recent division of Peckia into five subgenera, and we argue that the reduction of the acrophallic median stylus is an autapomorphic condition supporting the clade (Peckia + (Lipoptilocnema (Helicobia + Sarcophaga))). Our analysis shows that Peckiamyia is sister to Retrocitomyia, and Titanogrypa is sister to Villegasia, which together with Engelimyia form lineages that emerge in a basal divergence with regard to the clade with no median stylus. Alternative homology interpretations of the median stylus were studied and tested in a phylogenetic context. The median stylus and other phallic homologies were revisited and redefined. All studied genera were found to be monophyletic.

    ABSTRACT: With approximately 850 valid species, genus Sarcophaga Meigen (Diptera: Sarcophagidae) is one of the megadiverse genera of true flies. Species of this genus are widespread, showing the greatest diversity in the Holarctic, Oriental and Afrotropical Regions. They are extremely uniform in their external appearance, and their correct identification usually relies upon a close examination of the terminalia. In the framework of ongoing studies on relationships within Sarcophaga, a series of field trips were carried out in 2011-2012 in Europe, the Afrotropics and Australia, with the aim of collecting a wide representation of species for molecular and morphological analyses. We extracted DNA from 137 species representing 48 subgenera from the Palaearctic, Afrotropical and Australasian Regions. We obtained 817bp COI sequences for 144 species, as well as 924bp 28S sequences for 105 species. Additional sequences were taken from GenBank. Altogether, 144 species of Sarcophaga were included in the analyses. The datasets were analysed both separately and combined using parsimony, ML and Bayesian approaches. Results confirmed the monophyly of some of the major subgeneric groupings previously defined by morphology, with a few notable exceptions. The subgeneric placement of a recently discovered morphologically outlying species from Turkey is discussed based on these preliminary molecular results.

    ABSTRACT: The New World and largely Neotropical genus Peckia Robineau-Desvoidy, 1830 is revised with a key to all species. Peckia is considered a senior synonym of Guanoxipha Lehrer, 2012, n. syn. and of Sarcodexia Townsend, 1892, n. syn., the first one under Squamatodes Curran and the latter maintained as a valid subgenus, which here is redefined giving the new generic combinations Peckia (Sarcodexia) lambens (Wiedemann, 1830), n. comb. and P. (S.) notata (Lopes, 1935), n. comb.; and the new subgeneric affiliations P. (S.) aequata (Wulp, 1895), P. (S.) chirotheca (Hall, 1933), P. (S.) dominicana (Lopes, 1982), P. (S.) florencioi (Prado & Fonseca, 1932), P. (S.) roppai (Lopes & Tibana, 1982) and P. (S.) tridentata (Hall, 1937). Peckia virgo (Pape, 1994) is transferred from subgenus Euboettcheria Townsend, 1927 to subgenus Squamatodes Curran, 1927. Sarcophaga adolenda Lopes, 1935 is transferred from its current position in Peckia to the genus Retrocitomyia Lopes, 1982, n. comb. A total of 67 species are recognized and grouped in the subgenera Euboettcheria, Pattonella Enderlein, 1928, Peckia Robineau-Desvoidy, 1830 (sensu stricto), Sarcodexia and Squamatodes. Nine new species are described, viz., Peckia (Euboettcheria) santamariae n. sp. (Colombia), Peckia (Euboettcheria) cacao n. sp. (Costa Rica), Peckia (Euboettcheria) calixtoi n. sp. (Puerto Rico), Peckia (Euboettcheria) hernandosi n. sp. (Ecuador), Peckia (Pattonella) kladosoides n. sp. (Colombia), Peckia (Peckia) cocopex n. sp. (Costa Rica: Cocos Island), Peckia (Peckia) sarmientoi n. sp. (Ecuador), Peckia (Peckia) rosalbae n. sp. (Colombia) and Peckia (Sarcodexia) cocos n. sp. (Costa Rica: Cocos Island). The following new synonymies are proposed as junior synonyms under their respective species: under Peckia (Euboettcheria) tridentata (Hall, 1937) is Euboettcheria alvarengai Lopes & Tibana, 1982, n. syn.; under Peckia (Peckia) chrysostoma (Wiedemann, 1830) is Paraphrissopoda hugolopesiana Lehrer, 2006, n. syn.; under Peckia (Peckia) pexata (Wulp, 1895) are Sarcophaga concinnata Williston, 1896, n. syn., Sarcophaga otiosa Williston, 1896, n. syn. and Paraphrissopoda catiae Lehrer, 2006, n. syn.; under Peckia (Peckia) rubella (Wiedemann, 1830) is Sarcophaga capitata Aldrich, 1916, n. syn. and under Peckia (Squamatodes) trivittata (Curran, 1927) is Squamatodes stahli Dodge, 1966, n. syn. Lectotypes are designated for Sarcophaga aequata Wulp, 1895, Sarcophaga concinnata Williston, 1896, Sarcophaga otiosa Williston, 1896 and Sarcophaga volucris Wulp, 1895. Paraphrissopoda alvesia Lehrer, 2006 is deemed an unavailable name as no depository was given for the putative type material.

    ABSTRACT: In temperate studies on carrion flies assemblages is widely accepted that Calliphoridae followed by Sarcophagidae, Muscidae and Fanniidae are the most abundant families in terms of abundance. In the Neotropical region, consideration on this matter had been little studied. During a one-year survey, the abundance variation of these families assemblage of carrion flies in an anthropized Andean valley located in the province of Antioquia, was studied. From February 2010 to February 2011 two monthly sampling per site were performed, Van Someren Rydon traps baited with fish and chicken were settled in four localities, one per cardinal point with different landscape use. A total number of 33838 flies were collected distributed as follow: Calliphoridae (39%), Sarcophagidae (23%), Fanniidae (18%), Muscidae (16%), and small fraction of other dipteran families (4%). This trend in the families abundance was observed during the complete year except in May, March and August when sarcophagids were the most abundant. It is remarkable the alternate half-year abundance of Muscidae and Fannidae. No significance differences in flies’ abundance were observed according the climatic season, and sampling locality. Differences in flies abundance were found by month sampled where an increase pattern in the last months were evident. Differences also were found in family rank assessed, being Calliphoridae the most frequent. Accumulate number of Sarcophagidae contrast with others studies in tropical ecosystem where the second more frequent family is Muscidae probably due to the type and decomposition stage of the bait.

    ABSTRACT: The morphology of larval stages of Diptera (Insecta) is little known, especially in the case of Sarcophagidae family larvae. Interest in sarcophagid larvae studies has increased with the step forward of forensic entomology, where they are considered potential indicators of the time of death. Forensic studies show Peckia (Peckia) chrysostoma as one of the most important species in the Neotropical region. However, taxonomic identification of larvae is difficult due to the lack of knowledge of its morphology and useful taxonomic characters for identify them. Sealed microscope slides of first and second instar larvae were performed. The pseudocephalon, cephalopharyngeal skeleton, spinules, spiracular atrium and the posterior spiracles were studied. Morphological characteristics of larval instars I and II were described and illustrated.
