Etymology: Hemigrammus: Greek, hemi = half + Greek, gramma = letter, signal (Ref. 45335); silimoni: Named for Keve Z. de S. de Silimon, who collected the type series of the new species and in recognition for his long and continuous efforts in documenting the ichthyofauna from Mato Grosso.
Eponymy: Keve Zobogany de Szonyi de Silimon is a Brazilian biologist. [...] (Ref. 128868), visit book page.

Short description पहचान कुंजी | आकृति विज्ञान | मौरफोमैटरिक्स

पृष्ठीय सौफट रेज़ (सम्पूर्ण) : 11. The lower portion of the dorsal caudal-fin lobe with conspicuous ocellated caudal-fin blotch which is an autapomorphy which separates the new species from all congeners, and in fact from all remaining Characidae. The other members of Hemigrammus differ by having black pigmentation on the caudal fin either confined to the caudal-fin base (e.g., species belonging to the Hemigrammus ocellifer and Hemigrammus tridens groups, sensu), or as a discrete terminal bar (Hemigrammus marginatus), or finally as symmetrically-arranged black spots on the dorsal and ventral caudal-fin lobes (Hemigrammus bleheri and Hemigrammus rhodostomus) (Ref. 78749).

The type locality is about 50 m wide and 1.7 to 2.0 m deep, with swift-running, crystal-clear waters and with bottom comprising of sand and rocks. Reported to occur in areas of slack current near the river bank. Gut contents include algae and other vegetal matter (Ref. 78749).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01202 (0.00496 - 0.02912), b=3.10 (2.92 - 3.28), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.0 ±0.4 se; based on size and trophs of closest relatives

लौटाव (Ref. 120179): ऊंचा, न्यूनतम जनसंख्या दुगनी समय अवलागत 15 महीने। (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
