Etymology: Zaireichthys: Composed form Zaire river + Greek,ichtys = fish; the habitat of this fish (Ref. 45335); maravensis: The specific name of this species refers to the fact that its currently known distribution is restricted to Malawi, a name derived from the 16th century Maravi Kingdom, although it is likely to occur also in rivers flowing into Lake Malawi from Tanzania and Mozambique (Ref. 86935).

Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt) : 2; Rückenflossenweichstrahlen (insgesamt) : 5 - 7; Afterflossenstacheln: 0; Afterflossenweichstrahlen: 10 - 13; Wirbelzahl: 33 - 39. Diagnosis: This species differs from Zaireichthys kafuensis, Z. monomotapa, Z. pallidus and Z. rotundiceps in having the premaxillary tooth patch larger than 45% of mouth width; it differs from Z. conspicuus in the longer lateral line, 1.3±0.1 in standard length vs. 2.1±0.2, and colour pattern, lacking the bold blotches found in Z. conspicuus; and from Z. compactus in pigmentation pattern, with rows of elongate spots instead of the irregular blotches (Ref. 86935).

Found in fast-flowing streams and small rivers with clear water and a sandy bottom (Ref. 86935).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.0 ±0.4 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
