Etymology: Lamprologus: Greek, lampros = light + Greek, lagos = hare (Ref. 45335); markerti: This species is named for Jeffrey Markert whose initial analyses of cichlid population structure in the region of the large Inga Rapids stimulated the morphological study of this species (Ref. 97099).

وصف مختصر
مفاتيح التعريف | الوصف الخارجي | قياسات المظهر الخارجي
الأشواك الظهرية (المجموع) : 16 - 18; الأشعة الظهرية الناعمة (المجموع) : 7 - 8; شوكة شرجية: 4 - 6; أشعه شرجية لينه: 5 - 7; فقرات: 32 - 33. Diagnosis: Lamprologus markerti is readily distinguished from L. tigripictilis by the presence of 4-6 broad dark bars on the flanks vs. 7-10 narrow bars, and from L. werneri in the possession of 14 vs. 15 precaudal vertebrae (Ref. 97099). It differs from both L. tigripictilis and L. werneri in a reduced number of gill rakers on the first arch, 9-10 vs. 12-17; a longer head, 32.1-34.7% of standard length vs. 29.3-31.9 and 29.1-32.9% respectively; and a longer predorsal length, 33.0-35.9% of standard length vs. 29.3-32.7 and 28.5-32.6% respectively (Ref. 97099). Further, L. markerti lacks an intestinal loop present in both L. tigripictilis and L. werneri, and has a highly reduced infraorbital series often consisting only of the first infraorbital element (Ref. 97099).
This species appears to be a habitat generalist found over a range of substrates from marginal riffle and rocks near rapids, to stiller water habitats over sand and mud (Ref. 97099).
