Lamprologus sp. “Kinganga”
This Lamprologus, for once not one of the many new
species from Lake Tanganyika, was collected by Heiko
Bleher during one of his many collecting expeditions
in Africa. The male shown in the photographs, which
is the only specimen of this species collected thus far,
was caught in the Lower Zaïre (Congo River) near
Kinganga about 200 km downstream from the Zaïrean
The Lower Zaïre at Kinganga had been the site of
an earlier expedition by ichthyologists about twenty
years ago. An American expedition led by Tyson
Roberts and Donald Stewart collected many species
of fish here in 1973. Three years later both scientists
published the results of their expedition and in one of
the many plates accompanying the publication a small
cichlid is depicted with the caption Lamprologus
werneri. The type species of L. werneri (Poll, 1959:
108-109, Pl. XIX), however, was collected in the lower
part of Malebo Pool, a very shallow, lake-like widening of the lower Zaïre river. Malebo Pool is a frequently
visited site where exporters collect their aquarium
fishes. As well as Steatocranus casuarius (Buffalo
Head Cichlid), which is regularly exported in large
quantities from this area, L. werneri, usually under

trade names like “Lamprologus Congoensis” or
“Lamprologus Congolensis”, has also found its way
into many aquaria. Although this cichlid closely resembles the “new” Lamprologus sp. “Kinganga”, especially in its cylindrical shape, there are a number of
minor differences which suggest that we are dealing
with a distinct species and not with a geographical
variant of one species, namely Lamprologus werneri.
The male Lamprologus sp. “Kinganga” that I kept
for several years in one of my aquaria, grew to a length
of about 10 cm, which is several centimetres shorter
than the maximum length known for L. werneri. The
pattern of light spots on the dorsal and caudal fins is
much brighter in Lamprologus sp. “Kinganga” than
in L. werneri. Also the vertical markings on the dorsal
part of the body are narrower compared to those in L.
werneri. The relatively large cranial gibbosity of the
“new” species and the distinct markings on the scales
may be further, possibly typical, characteristics of this
species. Roberts and Stewart noted in their earlier
quoted publication that they too found differences
between these cichlids, and consequently treated both
forms as possible geographical variants of L. werneri.
As an aquarium inhabitant Lamprologus sp.
’Kinganga” is an undemanding, sometimes territorial
cichlid which accepts regular aquarium fare and tolerates any type of water with no noticeable distress.
Even larger fishes find it difficult to intimidate this
small cichlid; typical Lamprologus.
