Systematics
Sullivan et al. (2000) examined four species of Stomatorhinus (three unnamed plus S. walkeri) and all four grouped together as a monophyletic assemblage.
Lavou et al. (2012) found a sister relationship between Stomatorhinus cf. ater and Paramormyrops gabonensis and, what they call Paramormyrops sp. 'type 2' (magnostipes complex).
Sonet et al. (2018) found a sister relatioship between Stomatorhinus walkeri and Ivindomyrus sp. short Kouilou, and also a sister realtionship between this pair and Ivindomyrus sp. elongate Kouilou.
Biological Notes
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, Stiassny and Alter 2021). In particular there are at least twelve species, in five Families, which exhibit the troglomorphic features of reduced eyes and pigment:
Clariidae
Channallabes apus (Günther 1873) Teugels 1986
Dolichallabes microphthalmus Poll 1942
Gymnallabes nops Roberts and Stewart 1976
Platyallabes tihoni (Poll 1944) Poll 1977
Claroteidae
Notoglanidium pallidum Roberts and Stewart 1976
Mochokidae
Chiloglanis undescribed species "Kinsuka"
Mastacembelidae
Mastacembelus aviceps Roberts and Stewart 1976
Mastacembelus brichardi (Poll 1958) Vreven 2005
Mastacembelus crassus Roberts and Stewart 1976
Mastacembelus latens Roberts and Stewart 1976
Cichlidae
Lamprologus lethops Roberts and Stewart 1976
Mormyridae
Stomatorhinus microps Boulenger 1898
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.
