(Characins) > Distichodontidae
Etymology: Distichodus: Greek, di = two + Greek, stix, stichos = line, row (Ref. 45335); teugelsi: Named in memory of the late Guy Teugels (1954-2003), the first promoter of the project that resulted in the collection of this species.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; pelagic; pH range: 4.2 - 4.5. Tropical
Africa: Léfini and Alima basins in Republic of Congo, and middle Congo River main course in Democratic Republic of the Congo (Ref. 78699).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 5.7 cm SL male/unsexed; (Ref. 78699); 5.7 cm SL (female)
Diagnosis: 2 rows of bicuspid teeth on upper jaw and only 1 row of bicuspid teeth on lower jaw; 16 scales around caudal peduncle; no series of spots on flanks (Ref. 78699).
Found in riparian or flooded forest; in shallow as well as deep areas; in acidic waters due to humic acids (Ref. 78699).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01259 (0.00534 - 0.02968), b=3.00 (2.80 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
