Four new Neotropical species in the Hirtodrosophila hirticornis species group (Diptera: Drosophilidae).

Hirtodrosophila Duda, 1923 (Diptera, Drosophilidae) is a worldwide genus associated with fungi that encompasses 30 Neotropical species. They are gathered into four clusters: glabrifrons species group (Burla 1956), hirticornis species group (Burla 1956), magnarcus species group (Frota-Pessoa 1951), and thoracis species group (Grimaldi 1987), although there are still some ungrouped species. Nevertheless, their species richness is highly underestimated, and several unknown species of the genus have been sampled in different Brazilian regions.

Two new species of the new world genus Rhinoleucophenga (Diptera: drosophilidae).

The genus Rhinoleucophenga Hendel (1917) encompasses 21 described species but is still not well known as a taxon. Even the currently described species lack full descriptions, i.e.
