DUFEK, Matías I.  y  MULIERI, Pablo R.. Updating the distribution of mesembrinellid flies (Diptera: Mesembrinellidae) in Argentina with the first record of Mesembrinella bicolor. Rev. Soc. Entomol. Argent. [online]. 2023, vol.82, n.3, pp.37-41.  Epub 25-Ago-2023. ISSN 0373-5680.

During samplings carried out to evaluate the diversity of calyptrate flies (Diptera: Calyptratae) in northeastern Argentina, Mesembrinella bicolor (Fabricius, 1805) was first detected. This finding represents the second species of Mesembrinellidae from Argentina, after Mesembrinella bellardiana Aldrich, 1922 and the southernmost known record for a species of Mesembrinellidae. A brief diagnosis of both species is included.
