Actinopterygii (ray-finned fishes) > Characiformes (Characins) > Alestidae (African tetras)
Etymology: Alestopetersius: Greek, a = without + Greek, lestes = thief + Peters, 1877, naturalist, expeditionary in Asia;  conspectus: Conspectus, from the Latin, in reference to the conspicuous markings on the caudal fin and striking, bright coloration of the species in life (Ref. 89102).

Environment / Climate / Range Ecology

Freshwater; pelagic; pH range: 5.8 - 6.5.   Tropical; 21°C - 23°C (Ref. 89102)

Size / Weight / Age

Maturity: Lm ?  range ? - ? cm
Max length : 5.7 cm SL male/unsexed; (Ref. 89102)

Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 10; Anal spines: 0; Anal soft rays: 21 - 23; Vertebrae: 36 - 37. Alestopetersius conspectus, is distinguished from A. smykalai, A. leopoldianus, A. nigropterus, A. caudalis, and A. sp. "mbuji" in the possession of 12 (vs. 10) circumpeduncular scales (Ref. 89102). It is readily distinguished from A. brichardi, A. compressus, A. hilgendorfi, and A. tumbensis in the possession of a caudal-fin pigmentation consisting of a median black band extending to the caudal-fin margin and flanked by dense black bands in both upper and lower fin lobes (Ref. 89102). Alestopetersius bifasciatus, which shares similar caudal fin pigmentation, is distinguished from A. conspectus by the absence of a broad mid-lateral band on the body, and in tooth morphology (Ref. 89102). Mouth terminal, lower jaw prominent and slightly prognathous (Ref. 89102). Premaxilla with two teeth in outer row, each bearing five cusps, positioned opposite interspaces between and alternating with, four inner row teeth, each bearing 6-8 cusps; outermost premaxillary tooth is markedly compressed and elongate with 7 or 8 small evenly sized cusps and a low median cusp; dentary with four teeth in outer row, each bearing 6 or 7 cusps, outermost tooth smallest in jaw; no inner row teeth on dentary (Ref. 89102). In life all individuals are iridescent silver with greenish-copper reflections anterolaterally, becoming bluish on flanks and caudal peduncle; mid-lateral band is obscured anteriorly on body but clearly marked on caudal peduncle (Ref. 89102).

Africa: endemic to the Kwilu River, Congo River basin (Ref. 89102).

Biology     Glossary (e.g. epibenthic)

Found in shallow water (1–2 m) with a water temperature of 21–21.5°C and a pH ranging from 5.8–6.5; riverbanks variously covered with dense, undisturbed riparian vegetation, heavily degraded urban areas and cleared agricultural area; arnivorous as suggested by the short gut and large stomach and the remnants of ants and small midges found in all specimens examined (Ref. 89102).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5010   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01202 (0.00541 - 0.02673), b=3.00 (2.81 - 3.19), based on LWR estimates for this Subfamily-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  0.0   ±0.0 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 (10 of 100) .
