Etymology: Ptychochromis: Greek, ptyx, = fold + Greek, chromis = a fish, perhaps a perch (Ref. 45335); mainty: Named after the Malagasy word for black, mainty, referring to the species’ uniform dark pigmentation pattern in preservation and large black midlateral blotch in life (Ref. 105395).

Short description पहचान कुंजी | आकृति विज्ञान | मौरफोमैटरिक्स

पृष्ठीय रीढ़ (सम्पूर्ण) : 13; पृष्ठीय सौफट रेज़ (सम्पूर्ण) : 11 - 13; गुदा कांटा: 3; ऐनल सौफट रेज़: 8 - 9; जानवरों की रीड़ का जोड़: 27. Diagnosis: A Ptychochromis with palatine morphology typical of species on Madagascar’s east coast (Ref. 105395). 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 (Ref. 105395). 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 (Ref. 105395).

Diet is largely unknown, but stomach contains gastropod shells (Ref. 105395).
