Abstract
A new Lamprologus is described from the lower Congo River (LCR) in the Democratic Republic of Congo. Lamprologus
markerti, new species, is readily distinguished from L. tigripictilis and L. werneri, the LCR endemic lamprologines with
which it was once taxonomically conflated, in the possession of a reduced number of gill rakers on the first arch (9–11
versus 12–17), a longer head (32.1–34.7% SL versus 29.3–31.9 and 29.1–32.9% SL, respectively), and a longer predorsal
length (33.0–35.9% SL versus 29.3–32.7 and 28.5–32.6% SL, respectively). Further, L. markerti lacks a second intestinal
loop present in both L. tigripictilis and L. werneri, and has a highly reduced infraorbital series often consisting of a single
first infraorbital (lachrymal) element
