MORENO, Joanna; MASSAFERRO, Julieta; CABALLERO, Margarita  e  OSEGUERA, Luis. First record of the Pseudodiamesa branickii species-group (Diptera: Chironomidae: Diamesinae) from central Mexico. Rev. Mex. Biodiv. [online]. 2020, vol.91, e913228.  Epub 22-Dez-2020. ISSN 2007-8706.  https://doi.org/10.22201/ib.20078706e.2020.91.3228.

Larvae and pupae of the Pseudodiamesa branickii species-group (Makarchenko & Makarchenko, 1999) (Diptera: Chironomidae) were found in 2 high-altitude lakes (El Sol and La Luna, 4,200 m asl), in the crater of the Nevado de Toluca volcano, in central Mexico. This is the first record of the genus in Mexico, and its southernmost report from a location that represents a transitional zone between the Nearctic and Neotropical regions. New information on the ecology and biogeographical distribution of the species-group is given.
