Etymology: Amphilius: Greek, amphi = on both sides + Greek, leios = fat;  athiensis: The specific name athiensis refers to the Athi River system, where the species appears to be endemic; used as a noun in apposition (Ref. 85045).

Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 7; Anal spines: 0; Anal soft rays: 8 - 10; Vertebrae: 38 - 40. Diagnosis: Amphilius athiensis is distinguished from all other species of the A. uranoscopus group by its distinctive colouration consisting of many small dark spots on its head, body, and fins, vs. head, body, and fins not finely spotted; it also differs from A. grandis by having longer inner mandibular barbels, 33.3-42.0% of head length vs. 20.2-33.6%, from A. chalei, A. cryptobullatus, A. krefftii, and A. uranoscopus by the absence of distinct pale patches at the origin and insertion of the dorsal fin, and from A. cryptobullatus and A. krefftii by its forked caudal fin vs. emarginate; it also differs from A. krefftii by its more elongate body with 38-40 total vertebrae, vs. short body with usually 36 total vertebrae; it also differs from A. chalei by having a deeper body, body depth at anus 11.1-15.3% of standard length vs. 8.9-10.8%, a deeper caudal peduncle, caudal peduncle depth 10.1-12.6% of standard length vs. 7.1-9.7%, and shorter caudal peduncle, caudal peduncle length 14.6-18.3% of standard length vs. 19.0-21.9%; it also differs from A. cryptobullatus by having normally developed bilateral bony swimbladder capsules, vs. bilateral bony swimbladder capsules extremely large (Ref. 85045).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00447 (0.00173 - 0.01152), b=3.09 (2.87 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.0   ±0.3 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
