Unveiling details of the dry-leaf praying mantids: Insights into two species of Decimiana (Mantodea, Acanthopidae) and new records for Mato Grosso do Sul, Brazil

Acanthopidae is the third most diverse family within the Neotropical praying mantids with its genera presenting a high similarity with dry leaves in different levels of senescence or lichens and moss. It has nine genera that have received numerous taxonomic treatments throughout the history of Neotropical mantises’ studies. One of those genera, Decimiana Uvarov, 1940, was revised by Lombardo (2000) and, since then, three species have been added to the genus. In this study, we recorded two species of dry-leaf praying mantids, Decimiana tessellata (Charpentier, 1841) and Decimiana hebardi Lombardo, 2000, for the first time for Mato Grosso do Sul state in Midwest Brazil. A description of male genitalia of both species is provided, and the female genitalia of both species are described for the first time, setting the bases for taxonomic comparison across Neotropical Mantodea lineages, contributing to systematics and phylogenetic discussions.
