Teleostei (teleosts) > Gonorynchiformes (Milkfishes) > Kneriidae (Shellears)
Etymology: Kneria: From Kner, that studied fishes in the Imperial Museum of Vienna, with Jean Natterer (1817) (Ref. 45335).
Eponymy: Dr Rudolf Kner (1810–1869) was an Austrian zoologist specialising in ichthyology. [...] This is a toponym; the holoypes of these fishes were collected in Katanga Province (formerly part of the Belgian Congo, now the Democratic Republic of Congo). (Ref. 128868), visit book page.

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 11; Anal spines: 0; Anal soft rays: 10; Vertebrae: 41. Diagnosis: body depth 18-23.2% of standard length (SL); head length 20.3-24.3% SL; snout rounded, wider than long, 26.1-31.5% head length, 94.4-104.3% eye diameter (ED); eye diameter 26.1-30.2% head length; interorbital distance 100-117.4% ED; preorbital distance 38.9-47.8% ED; mouth ventral, wide; lower lip with weakly developed cutting edge; opercular apparatus (only well dveloped in males) consisting of an opercular suction disc followed by a striated, moderately developed postopercular part with about 12 ridges; dorsal and anal fins with 3 unbranched rays; dorsal fin positioned about 0.9-1.1 times closer to tip of snout than to caudal fin origin, inserted at about the same level as pelvic fins; anal fin about halfway pelvic fins and caudal fin origin; pectoral and pelvic fins with a single unbranched ray; pectoral fin 17.3-19.7% SL; body yellowish, dorsal surfaces darker, brownish; dark lateral band not very distinct (Ref. 2970). Remark: note that the first column in the comparative table in Ref. 2970 (p. 41) contains the morphometrics for K. katangae and the second for K. paucisquamata, contrarily to what is mentioned above the respective columns (T. Musschoot, pers. comm.).

Maximum TL was recorded at 5.5 cm (Ref. 2970).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5001 [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).

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