Etymology: oharai: Named after Dr. Willian Massaharu Ohara, a distinctive ichthyologist, for his extensive contributions to
knowledge of South American freshwater fishes, and his fundamental role in the professional history of LFCT, having generously donated dozens of species of Corydoradinae collected by him over the last decade; noun in a genitive case.

توصيف مختصر
كليدهاي شناسايي | ريخت شناسي | ريخت ستجي بوسيله انداره گيري
This species is distinguished by the following characters: with an oblique dorsolateral longitudinal dark stripe on flanks, starting at first dorsolateral body plate and gradually descending towards middle portion of caudal-fin base, variably extending diffuse on ventral lobe of caudal fin; with a moderately-developed posterolateral portion of scapulocoracoid, not expanded mesially; dorsolateral stripe not extending anteriorly and meeting its counterpart on head (Ref. 138114).
Body shape (shape guide): elongated; Cross section: oval.
Captured in small streams, tributaries of the rio Aripuanã upstream the Dardanelos-Andorinhas waterfalls complex, where the average width was estimated in 2.18 m ± 0.80, depth in 17.0 cm ± 7.6, water current in 3.83 m/s ± 7.4, dissolved oxygen in 1.18 mg/l ± 0.99, and temperature in 25.1 °C ± 2.0. In the rio Juruena basin, most specimens were collected in small and shallow isolated pools of intermittent streams, directly flowing into the rio Juruena, also occurring in larger/deeper streams, as the igarapé do Boi Preto. In these sites (rio Juruena basin), the streams have dense marginal vegetation, muddy or dark tea-colored water, and substrate composed by sand and/or clay, leaf litter, submerged logs and branches, and large rocks. In the rio Juruena basin, no additional Corydoradinae species was found in syntopy (Ref. 138114).
