Taxonomic note
Lopes et al. (2018) established a new genus for the species following confirmation that it is more closely related to Sublegatus than to Suiriri suiriri, and that there are significant and consistent differences from the three members of Sublegatus. Hence the proposed new genus Guyramemua Lopes et al. 2018 is accepted by the BirdLife Taxonomic Working Group, hence Suiriri affinis (del Hoyo and Collar 2016) becomes Guyramemua affinis (HBW and BirdLife International (2019).
Previously Suiriri affinis (del Hoyo and Collar 2016) was newly described as Suiriri islerorum by Zimmer et al. (2001). However, the type specimen of S. affinis previously believed to belong to S. suiriri was subsequently shown to relate to this species, and takes precedence (Kirwan et al. 2014).

Population justification: The global population size has not been quantified. The species is described as rare to locally fairly common. In shrubby areas with grass and scattered trees along the Agua Fria road near Chapada dos Guimar, for example, 1-2 pairs per km were recorded in limited roadside surveys (del Hoyo et al. 2004).
Trend justification: The species is feared to decline in line with the loss and conversion of its cerrado habitat.
An estimated decline of 13% occurred in the adult population at Estação Ecológica de Águas Emendadas, Brazil, between 2003 and 2007 (L. F. França and M. A. Marini in litt. 2008, França and Marini 2010). The drivers of declines are not well understood: this site is apparently well protected and has apparently suffered little anthropogenic alteration since its formal protection. However, on the basis of apparent rarity in other large protected areas of cerrado, it is precautionarily suspected that these declines are representative for the entire range and that they are continuing at this rate to the present day. Consequently, the total population is suspected to have declined by 24% over the past ten years.
