Histoire de nomenclature:

Répartition par pays:

Étymologie: Named for the American Ichthyologist Paul V. Loiselle, who collected the type series, in recognition of his many contributions to the understanding and conservation of Madagascar's freshwater fishes (Stiassny & Sparks, 2006).

Nom commun: Garaka (MG).

Types: holotype: AMNH 232462 (1), paratypes: AMNH 232458 (1), AMNH 237135 (5), AMNH 231249 (1), AMNH 231258 (3), MHNG 2676.095 (1), MNHN 2006-0781 (1).

Diagnose: A Ptychochromis exhibiting the eastern-type palatine morphology and 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 origin of (and often extending over) the anal fin, and by an overall dark grayish-green body coloration. Ptychochromis loisellei is further diagnosed by an apomorphic lateral expansion of the LPJ toothplate anteriorly, which obscures the underlying bone in dorsal view (Stiassny & Sparks, 2006).

Localité type: Northeastern Madagascar, Antsiranana Province, north of Sambava, Mahanara River at Antsirabe-Nord, just upstream of bridge over route N-5 (13° 58.49S; 49° 57.81E).

Distribution: Ptychochromis loisellei is currently known only from the Mahanara River and its tributaries in northeastern northeastern coastal Madagascar near the town of Antsirabe-Nord (Stiassny & Sparks, 2006).

cares

Conservation: Ptychochromis loisellei est évalué par l'Union Internationale pour la Conservation de la Nature dans la Liste Rouge des espèces menacées comme étant (EN) Menacée (2016). According to local fishermen, Ptychochromis loisellei is still relatively common throughout its limited range within the Mahanara River basin (Stiassny & Sparks, 2006).

Commentaires: Previously known as Ptychochromis sp. "Nor-east", (De Rham & Nourisat, 2002).
