Priocharax nanus, new species, is described from the rio Negro, Brazil. It is a miniature fish that retains as an adult the larval rayless pectoral fin, a diagnostic character of the genus. Priocharax nanus possesses fewer reductive features compared to congeners, P. ariel and P. pygmaeus, from which it can be distinguished by the presence of i,6 pelvic-fin rays (vs. i,5), the presence of the claustrum (vs. claustrum absent) and the presence of two postcleithra (vs. postcleithra absent). An updated list of 213 species of miniature Neotropical freshwater fishes is presented. The greatest diversity among them is represented by the Characiformes with 87 miniature species.Priocharax nanus, espécie nova, é descrita do rio Negro, Brasil. É um peixe miniatura que retém no adulto a forma larval da nadadeira peitoral, um caráter diagnóstico do gênero. Priocharax nanus possui um número menor de caracteres redutivos quando comparado aos congêneres, P. ariel and P. pygmaeus, dos quais pode ser distinguida pela presença de i,6 raios na nadadeira pélvica (vs. i,5), presença do claustrum (vs. claustrum ausente) e presença de dois pós-cleitros (vs. pós-cleitros ausentes). Uma lista atualizada de 213 espécies de peixes miniatura de água doce neotropicais é apresentada. A maior diversidade entre eles é representada pelos Characiformes, com 87 espécies miniatura.Key words: Heterocharacinae, Miniaturization, Reductive characters. (Weitzman & Vari, 1987). More recently, Priocharax ariel was also recorded in the region of Santa Isabel do Rio Negro, rio Negro basin (Lima & Toledo-Piza, 2001) and P. pygmaeus was collected from a small tributary of rio Solimões, in Amazonas, Brazil (Oliveira et al., 2009). Weitzman & Vari (1987) listed six diagnostic characters for Priocharax, the most conspicuous of which is the presence of a rayless pectoral fin fold in the adult, which is otherwise restricted to larval stages of characiforms and teleosts in general. Priocharax species also have the upper and lower jaws with a high number of tiny conical teeth, the adults are diminutive in size being among the smallest characiforms known, specimens have 16-22 branched anal-fin rays and only five branched pelvic-fin rays. In addition to the two species of Priocharax, the only other Characidae known to us that consistently has i,5 pelvic-fin rays is Cyanogaster noctivaga Mattox, Britz, Toledo-Piza & Marinho, another miniature characid from the rio Negro (Mattox et al., 2013).One year after describing the diminutive Priocharax, Weitzman & Vari (1988) provided a comprehensive review on miniaturization of South American freshwater fishes including a list of 85 species that either matured under 20 mm SL or did not exceed a maximum of 26 mm SL. The authors included 49 species of Characiformes in that original list, Priocharax nanus, new miniature species 230 nearly 60% of the total number of miniature species in South American freshwaters. Of their 49 miniature Characiformes, 46 were classified in the Characidae (including eight species of characidiines now...

“…The genus is atypical in having a mixture of characteristics of taxa belonging to the Gobionellinae and the Gobiinae. For example, species of Gobionellinae normally have two epurals (Pezold, 1993), but Nesogobius is variable, with some species having one epural and some two. In gobionellines, the interorbital canal is separated anteriorly between the eye, with paired anterior interorbital pores and posterior and anterior nasal pores.…”

Hoese, D.F. and Larson, H.K. 0000. Description of two new species of Nesogobius (Pisces: Gobioidei: Gobiidae) from southern Australia. Memoirs of Museum Victoria 63(1): 7-13.Two new species of Nesogobius are described from southern Australia and compared with described species Nesogobius pulchellus Castelnau and Nesogobius hinsbyi (McCulloch and Ogilby). Nesogobius greeni, sp. nov. differs from N. pulchellus in lacking a spine in the second dorsal and anal fi n and in lacking head pores. Nesogobius maccullochi sp. nov. differs from N. hinsbyi in having head pores and fewer dorsal spines and dorsal and anal rays.

“…The Gobioidei is a large suborder in the Perciformes comprising more than 2,000 species classified variously into three (Hoese and Gill, 1993), six (Pezold, 1993) or eight families (Nelson, 1994). They exhibit a wide range of life style from benthic to slow swimming life, and most species of specialized groups such as Gobiidae transform their two pelvic fins into a sucker as compared with less specialized groups such as Rhyacichthyidae and Odontobutidae which have separate pelvics (Hoese and Gill, 1993).…”
