Etymology: Chiloglanis: Greek, cheilos = lip + Greek, glanis = a fish that can eat the bait without touching the hook; a cat fish (Ref. 45335); msirii: The species name is dedicated to King Mwenda Msiri Ngelengwa (1830-1891); he founded and ruled the Yeke Kingdom of south-east Katanga, now DRC, from about 1856 to 1891 and was murdered for resisting Belgian colonial rule in his area; it is dedicated to the King Msiri in acknowledgement and in honour of his service and defence of the integrity of his people (Ref. 128503).

Краткое описание
определительные ключи | морфология | морфометрия
колючие лучи спинного плавника (общее число) : 2; членистые (мягкие) лучи спинного плавника (общее число) : 5; колючие лучи анального плавника: 0; членистые (мягкие) лучи анального плавника: 10 - 12; позвонки: 33 - 36. Diagnosis: Chiloglanis msirii can be distinguished from its congeners in the Congo basin by the following unique combination of characters: an oral disc without a mid-ventral cleft, vs. an oral disc with a well-developed mid-ventral cleft in C. asymetricaudalis, C. angolensis, C. carnosus, C. congicus, C. igamba, C. kalambo, C. kazumbei, C. lufirae, C. lukugae, C. macropterus, C. marlieri, C. micropogon, C. microps, C. orthodontus, C. pojeri, C. productus, C. reticulatus, C. ruziziensis, and shallow mid-ventral cleft in C. elisabethianus (Ref. 128503). Outside the Congo basin, C. msirii can be distinguished from all its congeners from southern Africa, except for C. swierstrai, by the following unique combination of characters: an oral disc without a mid-ventral cleft, vs. an oral disc with a well-developed mid-ventral cleft in C. anoterus, C. bifurcus, C. fasciatus, C. neumanni and C. paratus; and a forked caudal fin without apparent sexual dimorphism, vs. emarginate in both sexes in C. emarginatus and C. pretoriae (Ref. 128503). Finally, C. msirii can be distinguished from the most similar species, C. swierstrai, by a relatively robust body with few total number of vertebrae, 33-36, vs. a more slender body with a higher number of total vertebrae, 37-40; its relatively large body width at the pectoral-fin insertion, 22.0-27.2% of standard length vs. more slender, 17.3-20.3% of standard length; its deep caudal peduncle, 10.2-12.9% of standard length, vs. shallower, 8.3-9.8% of standard length; its long predorsal length, 34.4-41.8% of standard length, vs. shorter, 30.6-34.7% of standard length; and its long prepelvic length, 51.8-59.8% of standard length, vs. shorter, 46.1-51.9% of standard length (Ref. 128503).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = No PD50 data [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).
Trophic level (Ref.
69278): 3.2 ±0.4 se; based on size and trophs of closest relatives
устойчивость к внешним воздействиям (Ref.
120179): высокий, минимальное время удвоения популяции до 15 месяцев (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
