NOTES

New record for Mato Grosso do Sul. For a description, see Yacharoen et al. (2015). The species is often synonymized with the type species of the genus, butYacharoen et al. (2015) argue against this (q.v.) and prefer to keep the tropical material of this complex separate from the temperate material, based on morphological differences and polymorphisms in DNA sequences.
