“…argyrostoma do not match the pictures of Draber‐Monko et al () and Awad et al (). However, until further studies show whether or not the sculpturing is taxonomically useful, we agree with Leite and Lopes () that the shape of the teeth is more likely related to a supraspecific differentiation than a species‐specific separation.…”

“…At least the anterior and posterior spiracles and the cephalopharyngeal skeleton are described, drawn, or pictured for the third instar larvae of practically all species available in the literature. As regarding SEM descriptions, the sarcophagids have been barely and unevenly studied: the first instar larvae of about 70 European Miltogramminae species is known (Szpila, ; Szpila and Pape, , 2007, ); among the Paramachronychiinae, all the larval stages of Wohlfahrtia magnifica (Schiner, 1862) and first instar larvae of Sarcophila latifrons (Fallén, 1817) are known (Ruíz‐Martínez et al, ; Szpila, ); and from Sarcophaginae, the best studied genus is Sarcophaga , although several non‐Palaeartic species belonging to other genera have also been described (Leite and Lopes, ; Lopes and Leite, ; Mendoça et al, ). With regards to Sarcophaga , three species have been partially described (Aspoas, ), four species have descriptions of third instar larva stage alone (Kirk‐Spriggs, ; Pérez‐Moreno et al, ), and all the immature stages have been described for three more species (Awad et al, ; Draber‐Monko et al, ; Singh et al, ; Sukontason et al, , 2006; Suwannayod et al, ).…”

The Sarcophagidae are one of the most numerous groups of Diptera in the world, consisting of many species of forensic interest, whose immature stages are useful in the estimation of postmortem interval. The immature stages of some species of forensic importance still remain unknown or undescribed, like in the case of Sarcophaga (Liopygia) cultellata Pandellé, 1986, a species restricted to the Iberian Peninsula, south of France and north of Italy, which shares a ecological niche with species of the same subgenus, e.g., Sarcophaga (Liopygia) argyrostoma (Robineau-Desvoidy, 1830) and Sarcophaga (Liopygia) crassipalpis Macquart, 1839, making it necessary to lay the groundwork for a proper specific differentiation before it can be successfully applied in forensic practice. This study provides the first micromorphological description of all preimaginal stages of S. (L.) cultellata using light microscopy and scanning electron microscopy (SEM), the results of which allow the morphology of the main features to be followed during the immature life cycle. We propose a combination of features for distinguishing Liopygia from other sarcophagid subgenera, based on the current level of morphological knowledge of immature stages. S. (L.) cultellata can be differentiated from S. (L.) argyrostoma and S. (L.) crassipalpis in every immature stage by both light microscopy and SEM. The presence of tegumental warts and a fan-shaped anterior spiracle with a single row of 15-18 respiratory papillae allow distinguishing the third instar larvae of S. (L.) cultellata from other Sarcophaga species described hitherto by SEM. Identification keys based on light microscopy observations are provided, covering all the immature stages of Liopygia subgenus occurring in the Iberian Peninsula.

“…This diversity can be understood from the morphological differences in mouthparts of many immature sarcophagids. The bladelike lateral edges of mouth hooks in the first instar P. ruficornis differ markedly from other sarcophagids such as Oxysarcodexia confuse, Oxysarcodexia thornax, Chaetoravinia almeidai whose mouth hooks bear small, sharp teeth Leite and Lopes 1987). Ravinia belforti also shows a mouth hook with delicate pits and ridges .…”

Ultrastructure of all larval instars and puparium of Parasarcophaga ruficornis, a common flesh fly species in India, is presented using light microscopy and scanning electron microscopy for the first time. The principal diagnostic characters, i.e. the cephalopharyngeal apparatus, the cephalic segment, structure and orientation of spines, pupal respiratory horns, the structures of both anterior and posterior spiracles are illustrated and discussed. Information presented herein can be useful during forensic investigations involving this fly species.

Description of immature stages of the flesh flyPeckia(Sarcodexia)lambens(Wiedemann) (Diptera: Sarcophagidae) provides better resolution for taxonomy and forensics

The necrophagous and saprophagous flesh fly Peckia (Sarcodexia) lambens and other flesh flies are similar to one another in general external morphology. Owing to these similarities, larvae are often misidentified, which cause errors in forensic analysis. Here, to resolve these potential problems, we describe immature stages of Peckia (Sarcodexia) lambens using scanning and optical microscopy, in which we emphasize conspicuous characters for possible identification. The dorsal bridge reaches the parastomal bars in first instar larvae (in contrast with some other flesh flies). Additionally, in other larval stages, mouthhook shape, pseudocephalon, distribution of spines and the anal segment may be important characters to identify species. Figures are also included for characters clarification.
