Actinopterygii (ray-finned fishes) > Siluriformes (Catfish) > Amphiliidae (Loach catfishes) > Leptoglanidinae
Etymology: Zaireichthys: Composed form Zaire river + Greek,ichtys = fish; the habitat of this fish (Ref. 45335);  lacustris: The specific name, 'lacustris', refers to the first species of the genus to be known from a lacustrine environment (Ref. 86935).

Environment / Climate / Range Ecology

Freshwater; benthopelagic; depth range 10 - 30 m (Ref. 86935).   Tropical

Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

Length at first maturity / Size / Weight / Age

Maturity: Lm 1.7  range ? - ? cm
Max length : 2.2 cm SL male/unsexed; (Ref. 86935); 2.0 cm SL (female)

Short description Morphology | Morphometrics

Dorsal spines (total): 2; Dorsal soft rays (total): 4-5; Anal spines: 0; Anal soft rays: 9 - 11. This species is distinguished from all other members of the genus by the short snout, which is less than one third of the head length, and by its unique habitat, occupying empty snail shells in the lake (Ref. 86935). It is almost transparent in life, with three horizontal darker blotches and with head mottled (Ref. 86935). Preserved specimens are pale, with light brown marbling on nape and shoulders, a series of about ten faint brown blotches dorsally, about ten mid-lateral blotches the posterior of which are more elongated, and darker patches above bases of pelvic fins, above anal fin and at base of caudal fin (Ref. 86935).

Biology     Glossary (e.g. epibenthic)

Recorded from depths of 10-30 m in the southern part and at a depth of about 20 m at Sanga in the central portion of Lake Malawi; caught over sandy substrata near Monkey Bay in empty gastropod shells; inquiline with Pseudotropheus lanisticola in shells of gastropod Lanistes nyassanus, this co-existence is fortuitous and the catfish occupies probably the upper part of the shell which the cichlid cannot reach; both sexes attain maturity at a SL of about 17 mm; mature males take up territories in shells and the females may share these for some time before depositing their eggs; since no females with spent ovaries have been found it appears that they must leave the shells shortly after oviposition whereas the males remain in the shells, presumably to guard the brood; gut contents include remains of ostracods, cladocerans, copepods, chironomid larvae and small trichopteran larvae; some diatom frustules were also observed but may have taken fortuitously with invertebrate food items (Ref. 86935).

Phylogenetic diversity index (Ref. 82805):  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
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months ().
Vulnerability (Ref. 59153):  Low vulnerability (11 of 100) .
