🐟 Physical Description

Dorsal spines (total): 13; Dorsal soft rays (total): 11 - 13; Anal spines: 3; Anal soft rays: 8 - 9; Vertebrae: 27. Diagnosis: A Ptychochromis with palatine morphology typical of species on Madagascar’s east coast . It is distinguished from all congeners by uniform dark brownish to black colouration in preservation and in life by expansive, continuous (or nearly so), longitudinal black blotch on midlateral flank extending from posterior margin of opercle to caudal peduncle versus absent in P. inornatus, P. onilahy, P. curvidens, P. loisellei, P. insolitus, or comprising multiple distinct midlateral blotches or bars in P. ernestmagnusi, P. makira, P. grandidieri, and P. oligacanthus . Ptychochromis mainty displays little or no overlap of anterior supraneural relative to supraoccipital crest, versus marked overlap in some eastern congeners like P. makira and P. ernestmagnusi; in comparison to P. grandidieri, body depth as a percentage of standard length in P. mainty considerably less for similarly sized individuals and slope of head in profile less steep; further distinguished from P. grandidieri by fewer and more sparsely arranged teeth on second pharyngobranchial toothplate of upper pharyngeal jaw, vs. numerous, densely arranged teeth . : short and / or deep.
