Etymology: Alticorpus: Latin, altus = nutritious + Latin, corpus = body (Ref. 45335); macrocleithrum: From the Greek "makros" = large, big, tall and "cleithrum" = the bony element in the shoulder girdle. In this species, the cleithrum is exceptionally large (Ref. 55463).
Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic; depth range 30 - 150 m (Ref. 55908), usually 60 - 150 m (Ref. 55908). Tropical; 13°S - 15°S
Africa: endemic to Lake Malawi. Found at Cape Maclear and Monkey Bay.

(total): 15 - 16;
soft rays: 8 - 9. Diagnosis: cleithrum elongated, forming a clear prominence protruding on the chest, already visible in specimens of 53.0mm SL; sensory pores on the head greatly enlarged (Ref. 55908).
Typical deep-water species, with an even distribution below 60m (Ref. 55908). Found in areas where the bottom consist of diatomaceous ooze (Ref. 5595) but also on sandy habitats (Ref. 55908). Food may consist of invertebrates (Ref. 5595) and perhaps small fishes (Ref. 55463).

Estimates based on models
Phylogenetic diversity index (Ref. 82804
= 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01479 (0.00684 - 0.03200), b=2.98 (2.80 - 3.16), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.5 ±0.37 se; based on food items.
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153
): Low vulnerability (10 of 100).
