Classification / Names Common names | Synonyms | Catalog of Fishes(genus, species) | ITIS | CoL | WoRMS | Cloffa

Teleostei (teleosts) > Siluriformes (Catfishes) > Mochokidae (Squeakers or upside-down catfishes) > Chiloglanidinae
Etymology: Chiloglanis: Greek, cheilos = lip + Greek, glanis = a fish that can eat the bait without touching the hook; a cat fish (Ref. 45335);  dialloi: This species is named for Guinean fisheries biologist, Samba Diallo, who provided logistical support and assisted in the field during the 2003 and 2013 expeditions; his efforts are largely responsible for the success of the expeditions and the subsequent descriptions of different new species (Ref. 116018).

Short description Morphology | Morphometrics

Dorsal spines (total): 2; Dorsal soft rays (total): 5-6; Anal spines: 0; Anal soft rays: 9. Diagnosis: Chiloglanis dialloi is distinguished from C. normani, C. waterloti, C. longibarbis, C. occidentalis, C. kabaensis, C. kolente, and C. nzerekore in possessing more mandibular teeth in the functional row, and readily distinguished from C. polyodon and C. lamottei in having fewer mandibular teeth in the functional row; it can be distinguished from Chiloglanis aff. micropogon in possessing moderately long mandibular barbels vs. reduced or absent mandibular barbels; it is distinguished from C. tweddlei and C. pezoldi in having shorter pectoral and dorsal spines; it is distinguished from C. camarabounyi in having a shallower body depth at anus, 12.0-14.5% of standard length vs. 14.8-18.2%, and at the dorsal-fin origin, 15.3-17.7% of standard length vs. 16.3-22.5%, and a shorter dorsal spine; it can be distinguished from C. loffabrevum in having a smaller premaxillary tooth pad width, 15.1-16.6% of standard length vs. 16.9-20.2%, and length, 2.9-3.7% of standard length vs. 3.4-5.4%, a narrower anterior nare interspace, 4.1-4.3% of standard length vs. 4.5-6.3%, and a shorter pre-pectoral length, 29.0-32.6% of standard length vs. 31.9-37.1% (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
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
