Comments: Specimens were collected between 14:00 and 17:00 in a small tributary of the Rio Jamari, close to a bush of submerged macrophytes in a slow flowing part of the Rio Preto, approximately 200 m above rapids. It was collected with <i>Apistogramma resticulosa, Axelrodia lindeae, Axelrodia stigmatias, Hemigrammus bellottii, Hyphessobrycon aff. sweglesi, Leporinus</i> sp., <i>Nannostomus trifasciatus, Odontocharacidium aphanes</i> and <i>Satanoperca</i> sp. Three of these species are considered miniature: the characids <i>Axelrodia lindeae, A. stigmatias</i> and the crenuchid <i>Odontocharacidium aphanes</i>. This species and the three miniatures are mostly transparent, and with the larger <i>Hemigrammus bellottii</i> which has a predominantly translucent body in life, an ‘almost invisible league’ for the Rio Negro was proposed by Carvalho et al., 2006 (Ref. 128847 in Ref. 128819).
