Etymology: Ptychochromis: Greek, ptyx, = fold + Greek, chromis = a fish, perhaps a perch (Ref. 45335); loisellei: Named for Paul V. Loiselle, who collected the type series, in recognition of his many contributions to the understanding and conservation of Madagascar's freshwater fishes (Ref. 57663).
Eponymy: Dr Paul V Loiselle is Emeritus Curator of Freshwater Fishes at the New York Aquarium and a very enthusiastic aquarist. [...] (Ref. 128868), visit book page.

deskripsi pendek Kunci identifiaksi (pengenalan) | Morfologi | Morfometrik

Duri punggung (Keseluruhan (total)) : 13 - 14; duri punggung lunak (Keseluruhan (total)) : 12 - 13; Duri dubur: 3; Sirip dubur lunak: 8 - 9; vertebrata, bertulang belakang: 27 - 28. It is distinguished from all congeners by a unique pigmentation pattern and coloration comprising an expansive, generally vertically oriented, black band or blotched region of black pigment below the lateral midline and just anterior to the origin of the anal fin, and by an overall dark grayish-green body coloration (Ref. 57663). Moderately deep-bodied and lateral compressed (Ref. 57663).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5010 [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): 3.4 ±0.5 se; based on size and trophs of closest relatives

Daya lenting (Ref. 120179): Tinggi, Waktu penggandaan populasi minimum kurang dari 15 bulan (Preliminary K or Fecundity.).

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