Etymology: Curculionichthys: Derived from the from the Latin 'curculionem' (elongated snout) and from the Greek 'ichthys' (fishes), in reference to the relatively elongated snouts of the fish species included in this genus..
Environment: milieu / climate zone / depth range / distribution range

Morphology | Morphometrics
soft rays: 6. Differs from all other known species of Hisonotus by the combination of a pair of rostral plates covering the tip of the snout; lateralis canal in almost every plate along length of body; lateral line uninterrupted by gaps, almost complete, with 22 perforated plates + 1 to 3 plates with no canal; a pectoral spine that is smooth and lacks odontodes along its posterior dorsal margin for a distance more than one-half of its width; and a scapular bridge that is completely exposed or with a very reduced median pair of arrector fossae (Ref. 53011).
Inhabits streams, with banks covered by vegetation partially submerged into the water (Ref. 53011).

Phylogenetic diversity index (Ref. 82805
= 0.5005 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months ().
Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
