Etymology: Paretroplus: Name from the Greek 'para' meaning 'on the side of'; in taxonomy it is commonly used in generic names to express similarity or relatedness; in the present case it would mean 'next to Etroplus' (S.Kullander, pers.comm. 3/11).;  loisellei: Named for Dr. Paul V. Loiselle, Emeritus Curator of Freshwater Fishes at the New York Aquarium (WCS).

Short description Morphology | Morphometrics

Dorsal spines (total): 18 - 20; Dorsal soft rays (total): 11-13; Anal spines: 9-10; Anal soft rays: 9 - 11; Vertebrae: 31 - 32. This species is distinguished from all congeners except P. damii by the presence of a triangular, black pectoral-axil patch in combination with the absence of a series of prominent vertical bars on the flank; in life, unstressed individuals can easily be distinguished from all congeners by the presence of a broad, vertical brick red or pale yellow band on the anterior half of the flank. Paretroplus loisellei is distinguished from P. damii by the presence of a more or less straight gular region in lateral view (vs. rounded and convex), such that the ventral margins of the preopercle and interopercle are essentially horizontal; oral jaws are horizontally oriented (vs. strongly oblique); lips are enlarged and fleshy (vs. thin); snout is elongate and curved, creating a beaked appearance (vs. short and straight); enlarged symphyseal teeth in the upper jaw possess distinct, sharp lateral cusps (vs. poorly developed and rounded); base coloration uniform dark brownish-gray in preservation (vs. considerably lighter golden brown overall and frequently retains a faint, pale broad band on the anterior region of the flank); have a distinctive bright golden breeding coloration (vs. brick red). Owing to convex premaxillary pedicels, this species exhibits a prominent indentation marking the transition from the dorsal margin of the premaxillary ascending process to the supraoccipital crest (Ref. 86507).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5001   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01122 (0.00514 - 0.02450), b=3.04 (2.87 - 3.21), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic Level (Ref. 69278):  2.9   ±0.3 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (21 of 100) .
