“…Despite the large number of freshwater teleost species currently known, few studies address ontogenetic aspects. Being the surveys more focused on evolutionary, ecological or descriptive aspects for several fish species from different watersheds (Andrade et al, ; Arashiro et al, ; Assega, Birindelli, Bialetzki, & Shibatta, ; Bialetzki et al, ; Costa & Neto, ; Faustino, Makino, Neumann, & Nakaghi, ; Gavaia, Dinis, & Cancela, ; Honji, Tolussi, Mello, Caneppele, & Moreira, ; Maciel, Júnior, Donzele, Lanna, & Menin, ; Miquelarena, Ortubay, & Cussac, ; Suzuki & Pompeu, ; Vrtílekv & Reichard, ; Zacardi, Silva, Bittencourt, Costa, & Nakayama, ). Thus, there is a gap regarding the ontogenetic aspects of these species, which is a fundamental knowledge as a support for taxonomic and fisheries biology studies.…”

Summary Aiming to provide data on the biology of Leiarius marmoratus, which will aid in its production in captivity, as well as in studies for its preservation in the environment, this work had as objectives: analyze and describe main morphological alterations during larval ontogeny of the species. We analyzed 205 individuals, obtained by induced reproduction (Colpani Pisciculture) and kept in CEPTA/ICMBIO, Pirassununga, São Paulo, Brazil. Analyses were performed from hatching moment to 30th day. The specimens were classified into two periods: larval (Stages: vitelline, pre‐flexion, flexion, post‐flexion) and juvenile. Hatched larvae showed ident chromatophores only at anterior and posterior extremities of yolk sac. The standard length ranged from 2.16 mm (yolk) to 28.84 mm (Youth). Dorsal fin rays were initially observed at flexion stage (12–14 rays). Major alterations occurred during post‐flexion/juvenile stage, when dorsal, pectoral, pelvic, anal, and caudal fins were observed and pigmentation intensified throughout the lateral region, forming bands in the body, one between the end of the head and beginning of dorsal to pelvic fin, and another one beginning at dorsal to caudal peduncle and four longitudinal at the head.

Fishes in early developmental stages frequently have morphological features that differ from those of adult stages, and many characters found later in ontogeny are not available in initial stages. Hence, morphological descriptions of early stages are useful to provide information for the identification of eggs and larvae, a knowledge still restricted among Neotropical fishes. We studied the development of Heterocharax macrolepis, a heterocharacine whose adult specimens from the aquarium trade were kept and spawned at around 23-24ºC. A developmental series of 51 specimens was preserved, ranging from 3.2 mm notochord length to 18.6 mm standard length, covering approximately the first 73 days post-hatching. We described the development of main morphological features emphasizing those useful in the identification of H. macrolepis larvae (i.e., appearance of preopercle spine and development of the pseudotympanum). We also compared H. macrolepis with photographs taken of live larval specimens of Gnathocharax steindachneri, recently included in the Heterocharacinae. Both species have a yolk sac with a small rounded projection directed posteroventrally. Although this information is not yet available for all pertinent taxa, the different yolk sac shape in other representatives of the Characiformes may indicate that this peculiar yolk sac represents an additional synapomorphy of the Heterocharacini.Peixes em estágios iniciais de desenvolvimento frequentemente apresentam características morfológicas distintas dos adultos e muitos caracteres presentes em estágios avançados não são disponíveis em estágios iniciais. Assim, descrições morfológicas dos estágios iniciais de desenvolvimento de peixes são úteis por fornecerem subsídios para a identificação de ovos e larvas, um conhecimento ainda escasso entre peixes Neotropicais. Estudamos o desenvolvimento de Heterocharax macrolepis, espécie de Heterocharacinae cujos exemplares adultos provenientes do aquarismo foram mantidos e reproduzidos entre 23-24ºC. Uma série de desenvolvimento de 51 exemplares foi preservada, medindo entre 3,2 mm de comprimento da notocorda e 18,6 mm de comprimento padrão, incluindo os primeiros 73 dias pós-eclosão. Descreveram-se detalhadamente os principais aspectos morfológicos, enfatizando características úteis na identificação de larvas de H. macrolepis (i.e., surgimento do espinho do pré-opérculo, desenvolvimento do pseudotímpano). Comparamos H. macrolepis com fotografias de larvas vivas de Gnathocharax steindachneri, recentemente incluída em Heterocharacinae. Ambas espécies possuem saco vitelínico com pequena projeção arredondada póstero-ventral. Ainda que a informação não esteja disponível para os táxons pertinentes, o distinto formato do saco vitelínico em outras linhagens de Characiformes pode indicar que esta forma do saco vitelínico peculiar represente sinapomorfia adicional de Heterocharacini.
