A new genus and species, Petrolina bifasciata gen. nov., sp. nov. (Diptera: Sarcophagidae, Sarcophaginae), with only two black stripes dorsally on thorax, is described from both sexes. The type material was collected in fragments of seasonally dry tropical forest in the state of Pernambuco, northeastern Brazil. The new genus and species is morphologically similar to genera Rafaelia Townsend and Malacophagula Bequaert. However, the atypical two thoracic black stripes and phallic morphology give evidence to the proposal of a new genus in Sarcophaginae.

Samples from 1,254 MacQueen's bustards (Chlamydotis macqueenii) were sent for parasitological examination to the department of parasitology of the Central Veterinary Research Laboratory between 2003 and 2022. The birds originated from sanctuaries where confiscated birds were kept but also from from zoos and private collections or were bred in captivity and released to conservation areas where they got injured or died for various reasons. The material consisted of mainly of intestines and faecal samples as well as heads, stomachs, muscles samples and cysts, isolated helminths, ecto-parasites and fly larvae.

The nocturnal behaviour and reproduction patterns of Sarcophagidae species during the scotophase are largely unexplored for species in the Neotropical region. The aim of this study was to assess the light regimes under which females of Peckia (Peckia) chrysostoma (Wiedemann, 1830) and Peckia (Sarcodexia) lambens (Wiedemann, 1830) would larviposit and understand how these variables influence intrauterine development in these flies. The experiments were conducted in an experimental room (lux = 100) in two independent experiments: I.

An annotated checklist of the Sarcophagidae of Jamaica is presented based on material collected from 2018 to 2024, supplemented with specimens in museum collections as well as literature records. The checklist comprises 45 species from 21 genera, of which 23 species from 15 genera were collected during the present study and identified based on male terminalia. The following species are recorded from Jamaica for the first time: Dodge, Peckia (Sarcodexia) dominicana (Lopes), Tibana & Lopes, and Lepidodexia (Harpagopyga) diversipes (Coquillet).

Article Synopsis
- Forensic entomology uses fly species on corpses to help estimate the time of death, but current identification methods are labor-intensive and costly due to a lack of specialists.
- This paper suggests using computer vision and deep learning techniques to classify flies into specific families and genera, which could streamline the process and improve accuracy, especially when using drones for remote searches.
- Two deep learning models, MobileNetV3-Large and VGG19, were evaluated, achieving high accuracy rates of 99.39% and 99.79%, with MobileNetV3-Large being faster in processing time, indicating great potential for these technologies in forensic and emergency situations.
