ABSTRACT
The puparia of Merosargus cingulatus Schiner, 1868 and Ptecticus lanei James, 1941, two Neotropical species of Sarginae (Stratiomyidae), are described and illustrated based on 19 and 17 immatures of each species, respectively. The specimens were collected in rotting vegetal material in Carambe, state of Paran, Brazil. Images of reared adults of both species are provided, allowing future identifications of specimens. New distributional records include the first occurrences of M. cingulatus in the Brazilian states of Cear, Maranho, Mato Grosso do Sul, and Rio de Janeiro. With these two new descriptions, immature stages (6th instar and/or puparium) of 29 species of Sarginae are now known, with only eight species known from the Neotropical Region.

Popularly known as fungus gnats, Mycetophilidae are found in humid environments usually associated with mushrooms and decaying wood. Their immature forms often feed on fungus fruiting bodies. Similar to most bibionomorphans, mycetophilids need due attention concerning their taxonomy and information on their natural history, especially in the Neotropical region. This work describes Monoclona carambeiensis sp. nov., a new species of Monoclona Mik, and furnishes information on the morphology of adults and immatures, besides notes and photographs on the life cycle of the species. Immature forms present on a piece of decaying wood with lichens and fungi were collected from Carambe, Paran, and reared in the laboratory. The emerged adult male was fixed in 80% ethanol. This is the first study describing an immature of a Neotropical species of Monoclona, and also the first record of the genus in the state of Paran, Brazil. This is the third Neotropical species of Mycetophilidae to have its life cycle described, for a fauna with over 1,100 known species.

Roraima is a Brazilian state located in the northern portion of the Amazon basin, with few studies regarding its biodiversity. The Ecological Station of Maracá (Brazil, state of Roraima) harbors the third largest Brazilian pluvial island and is composed of a transitional landscape of savanna and Amazon rainforest components. Despite its ecological importance and strategic localization, few studies covered the dipterofauna of this locality. An updated checklist addressing 41 families of true flies (Diptera) occurring in Roraima is presented based on the literature and the specimens collected during a field expedition that occurred in 2015. This checklist brings several improvements such as new records of 165 taxa to the state of Roraima, 29 taxa to Brazil, and 259 morphotypes, mostly likely representing undescribed species.(AU)
