Etymology: Chiloglanis: Greek, cheilos = lip + Greek, glanis = a fish that can eat the bait without touching the hook; a cat fish (Ref. 45335); tweddlei: This species is named for Denis Tweddle, of the South African Institute for Aquatic Biodiversity (SAIAB), who collected most of the type material and provided the specimens; and he is recognized for his ongoing contributions to ichthyological research in Africa (Ref. 116018).

Kurzbeschreibung Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt): 2; Rückenflossenweichstrahlen (insgesamt): 4-6; Afterflossenstacheln 0; Afterflossenweichstrahlen: 9 - 10. Diagnosis: Chiloglanis tweddlei is distinguished from C. waterloti, C. normani, C. occidentalis, C. nzerekore, C. longibarbis, C. kabaensis, and C. kolente in having more mandibular teeth in the functional row; it can be easily distinguished from C. polyodon and C. lamottei in having fewer mandibular teeth in the functional row, and from Chiloglanis aff. micropogon in having moderately long medial and lateral mandibular barbels vs. absent or reduced barbels; it is distinguished from C. dialloi, C. loffabrevum, and C. camarabounyi in having longer dorsal and pectoral spines; it can be distinguished from C. pezoldi in having a wider premaxillary tooth patch, 15.3-18.2% of standard length vs. 12.2-15.8%, and in having more premaxillary teeth in four rows vs. fewer teeth in three rows (Ref. 116018).

This species was collected in a medium-sized stream (3-12m) with mostly sand and bedrock ridges, as well as, fallen trees and undercut tree roots (Ref. 116018).

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=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.4 se; based on size and trophs of closest relatives

Widerstandsfähigkeit (Ref. 120179): hoch, Verdopplung der Population dauert weniger als 15 Monate. (Preliminary K or Fecundity.).

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