Neolamprologus wauthioni (holotype)
Tribe / Genus: Lamprologini / Neolamprologus
Type locality: Between Albertville and Katibili, 1 km off shore, Lake Tanganyika.
Biotope: The type specimens were collected at relatively high depth (35 m), probably over an intermediate or sandy zone associated with Neothauma snails.
Geographic distribution: Known only from preserved specimens collected on the western Congolese coast south of Albertville (now Kalemie), from two areas: about 15 km south and about 35 km south (Rutuku).
Typical adult size: Maximum known size (type series) is 53 mm.
Sexual dimorphism: Sexual dimorphism is not documented; males are possibly larger than females.
Diet: Gut contents of the largest examined individual (53 mm) contained small crustaceans and sand.
Breeding: No breeding observations are available.
The species is considered a substrate spawner; because the types were collected with Neothauma snails, it has been suggested that it could occasionally use shells.
Special notes: Neolamprologus wauthioni is a small lamprologine similar in size and overall shape to shell-dwelling members of the Neolamprologus ocellatus species group, with which it was confused for a long time.
It is separated from that group by multiple characters, including fewer anal spines (6 instead of 7–9), elongated pelvic fins (rather than rounded), and a higher vertebral count (31 versus 29), with a higher ratio of abdominal vertebrae (13/17 versus 11/18).
Its closest relative has been proposed to be Neolamprologus ventralis from the same coast but farther south; the two differ in scale counts in the longitudinal series (30–31 versus 34–36), gill raker counts (6–7 versus 4–5), and caudal fin shape (rounded versus notched).
The species has not been imported and has not been maintained in aquaria; care has been presumed to resemble that of Neolamprologus ventralis.
