Etymology: Iheringichthys: Because of Hermann von Ihering, 1850-1930; He arrived in Brazil in 1880 and settled in Rio Grande as phisician and naturalist. Expert in birds, fishes and molluscs; 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.

Dorsale stekels (totaal) : 2; Dorsale zachte stralen (totaal) : 6; Anale zachte stralen: 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 (Ref. 89852).
