MACHADO, Angelo B.M.. Carajathemis simone, new genus and species from Brazil (Odonata: Libellulidae). An. Acad. Bras. Ciênc. [online]. 2012, vol.84, n.4, pp.1039-1049. ISSN 0001-3765.

Carajathemis simone n. gen., n.sp. from the state of Pará, Brazil, is described and illustrated based on 22 specimens collected in a "canga" (laterite) lake within the forest at the Flona de Carajás, Parauapebas Municipality. The new libellulid genus fits in the subfamily Sympetrinae and the male keys out to Erythemis in Garrison et al. (2006). The new taxon has a combination of characters that makes it different from all genera of Sympetrinae including Erythemis. The species is remarkable by its large size, pleural striping and especially by the complex and strongly dimorphic leg armature. It seems to be restricted to shallow, rainfall-dependent, iron-rich lakes.
