“…Recently, cryptic diversity doubling the original number of valid species was detected within the genus Curimatopsis (Melo, Ochoa, Vari, & Oliveira, ). The Hoplias malabaricus species complex has been receiving particular attention during recent years (Mattox, Bifi, & Oyakawa, ) and two new species (Azpelicueta, Benítez, Aichino, & Mendez, ; Rosso et al, ) have been formally described recently. Cryptic diversity in the freshwater pufferfish genus Colomesus (Amaral, Brito, Silva, & Carvalho, ), and in pencilfishes of the genus Nannostomus (Benzaquem, Oliveira, da Silva Batista, Zuanon, & Porto, ) have also been revealed.…”
