Description: Dorsal spines (total): 2; Dorsal soft rays (total): 6; Anal soft rays: 11 - 13. Can be diagnosed by the comparatively fine serration along the anterior margin of the pectoral-fin spine, an adpressed dorsal-fin remote from the adipose-fin origin, a large eye (23.2-31.2% of head length), narrow interorbital (16.2-23.0% of head length), long snout (42.0-51.0% of head length), long postorbital length (30.6-34.0% of head length), low adipose fin (4.8-7.8% of standard length), eye diameter 97.0-140.0% of interorbital length, and body with numerous, small dots irregularly scattered on flanks, especially marked on anterior half of flank (Azpelicueta, M.M. and H.A. Britski, 2012). Habitat: The species is found in Brazil from the upper rio Paraná, in Jupiá (Três Lagoas Municipality, Mato Grosso do Sul State) and Ilha Solteira Municipality (São Paulo State). All specimens of Iheringichthys examined from those areas belong to I. syi. Most -and possibly all- records of Iheringichthys labrosus from those areas likely correspond to I. syi. Etymology: The specific name syi: The Guaraní word syi means straight, alluding to the fine serration present on anterior margin of the pectoral-finspine. The name is applied as an adjective. |

IUCN Red List |
Iheringichthys syi is known only from the type series, from the Jupiá and Ilha Solteira region, upper Paraná basin. The recent description of the species prevents knowledge of its distribution area, compromising the assessment. The population is unknown, as are the threats. Therefore, Iheringichthys syi was listed as Data Deficient DD (Dystolen). A review of the material collected in the upper Paraná is recommended (IUCN 2022). |
