Description
Heteragrion obsoletum: Selys 1886: 57–58 (description of ♁ from Minas Gerais state; mention that the appendages were missing);— Williamson 1919: 29 (general remarks);— Garrison et al. 2010: 88 (list of Heteragrion species);— Souza et al. 2013: 1368–1369 (misidentification, it is in fact H. cyane; fig. 2);— Machado & Souza 2014: 95, 97–98 (remarks and differences from H. cyane);—Vilela et al. 2019: 590–593 (remarks and differences with H. denisye; images of the original labels; figs. 1, 5);— Cezário & Guillermo-Ferreira 2021: 78–86 (remarks and differences with H. gorbi).
Material examined. None, only known from type holotype, which was lost (Vilela et al. 2019), originally housed at RBINS.
Known distribution. Brazil (Southern Minas Gerais state).
Diagnosis and remarks. Described from a single male collected in Caxambu, Minas Gerais state, this species has not been collected again, despite some search in that area by A.B.M. Machado (pers. comm. in 2019). Because of this, the assessment of H. obsoletum in the IUCN Red List is Data Deficient (Vilela & Guillermo-Ferreira 2021i). According to Selys (1886), this species can be separated from the other congeners by the broad shape of the MP plate, which has a rounded apex. Vilela et al. (2019b) made a thorough analysis of this enigmatic species, separating it from H. denisye and other congeners.
