Data from: New geographic record in eastern Amazon Forest and potential distribution of Amphidecta calliomma (Lepidoptera: Nymphalidae)

<p><em><span>Amphidecta</span></em><span> <em>calliomma</em> is a butterfly species that occurs in Colombia, Bolivia, Peru, Venezuela, Ecuador, Panama and Brazil (in the states of Mato Grosso, Mato Grosso do Sul, Rondônia and Pará). Here, we present a new occurrence of <em>A</em>. <em>calliomma</em> in the Carajás National Forest (Pará, eastern Amazon), expanding the known distribution of the species. We also provide Species Distribution Model comparing the contribution of the new occurrence to species area of occurrence projections, supporting future field research. The projections reveal an expansion of area of occurrence for <em>A</em>. <em>calliomma</em> located mainly in the southeast portion of Amazon Forest. Despite its wide distribution, the small number of records of <em>A</em>. <em>calliomma</em> may indicate that the species has a low detectability in surveys. This study provides support for new surveys and reduces the knowledge gap about <em>A</em>. <em>calliomma</em>, thus supporting its conservation.</span></p>
