Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenweichstrahlen (insgesamt) : 14 - 19; Afterflossenweichstrahlen: 17 - 19; Wirbelzahl: 26 - 27. Differs from all other species of the subgenus Simpsonichthys by having longitudinal rows of light blue dots on flank in males (vs. absence) and a long filamentous ray on tip of dorsal fin in males, reaching the posterior position of caudal fin (vs. reaching basal portion of caudal fin). Can be differentiated from all congeners by the unique combination of the following characters: pelvic fin present (vs. absent), second pharyngobranchial teeth absent (vs. present), ventral process of posttemporal short (vs. long), 18-19 dorsal-fin rays in males and 14-15 in females (vs. 15-17 in males, 12-13 in females), long filamentous ray on tip of dorsal fin males (vs. filamentous rays short or absent), five alternating bright blue and pink to red bars on head side in males (vs. never a similar color pattern), pectoral fin pink with blue spots in males (vs. hyaline), and absence of black spots on dorsal fin in males (vs. presence of black spots on basal portion of dorsal fin). Caudal fin round (Ref. 58746).

Inhabits temporary canals at floodplains (Ref. 58746).

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=0.01995 (0.00906 - 0.04395), b=3.01 (2.83 - 3.19), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.1 ±0.4 se; based on size and trophs of closest relatives

Widerstandsfähigkeit (Ref. 120179): hoch, Verdopplung der Population dauert weniger als 15 Monate. (Preliminary K or Fecundity.).

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