Roberts and Stewart 1976
Holotype: MCZ 50248. Paratype: MCZ 50249.
Type locality: Lower Congo River rapids near Bulu (5o1'S, 14o1'E). During a study of the Congo River Lamprologus species Schelly and Stiassny (2004) only had the holotype and paratype to study but later collection trips ???
Schedel et al. (2018, 2019) recognize several novel mitochondrial lineages and one of them is proposed as a monophyletic clade for the Lamprologus of the Lower and Central Congo drainage, including Lamprologus lethops. The type species of the genus (Lamprologus congoensis Schilthuis 1891) is not part of this clade and it is likely that any future revision of the tribe Lamprologini will provide a replacement generic name for this group (L. mocquardi, L. markerti, L. tigripictilis, L. lethops, L. teugelsi and L. sp. Kwango).
The lower Congo River, and especially the northern and southern rapids below Pool Malebo, are home to many endemic species (Roberts and Stewart 1976, Bailey 1986, Thieme et al. 2005, Mamonekene 2005, Alter et al. 2015, Alter et al. 2017, Stiassny 2016). In particular there are at least eleven species, in five Families, which exhibit the troglomorphic features of reduced eyes and pigment:
These features probably evolved because these species live at depth within the rapids and spend their whole lives in permanent darkness, analagous to life in caves. The ocular and craniofacial anatomy of several of these species have been studied (Schobert et al. 2010, 2011, 2013) but almost nothing else is known about these animals.
