Etymology: Chiloglanis: Greek, cheilos = lip + Greek, glanis = a fish that can eat the bait without touching the hook; a cat fish (Ref. 45335)igamba: The specific name refers to the type locality of this species, Igamba Falls on the Malagarasi River; this is the first major series of waterfalls encountered while navigating upriver from Lake Tanganyika, and is a potential site for a hydroelectric dam; used as a noun in apposition (Ref. 87986).

توصيف مختصر كليدهاي شناسايي | ريخت شناسي | ريخت ستجي بوسيله انداره گيري

خارهاي باله پشتي (کل) : 2; شعاع نرم باله پشتي (کل) : 5 - 6; خارهاي باله مخرجي: 0; شعاع نرم باله مخرجي: 9 - 11; مهره ها: 33. Diagnosis: Chiloglanis igamba is a sexually dimorphic species in which the caudal fin of adult males is relatively truncate, but with the middlemost rays moderately elongated; females and juvenile males of this species in contrast exhibit a gently forked caudal fin; sexual dimorphism of the caudal fin is also apparent in several other species of Chiloglanis, including the following from various tributaries flowing into Lake Tanganyika: C. trilobatus, C. kalambo, C. productus and C. asymetricaudalis, but the particular shape of the caudal fin in C. igamba is unique among all congeners (Ref. 87986). The most similar sexually dimorphic caudal fins are found in males of C. trilobatus and C. kalambo, where the middle most rays form a third lobe; the trilobate caudal-fin shape in these species can be distinguished from the shape in C. igamba by the areas between upper, middle and lower lobes, which are notably recessed; in C. igamba these recessed areas are absent and clearly trilobate shape is not evident; Chiloglanis igamba is further distinguished from C. trilobatus and C. kalambo by a shorter adipose-fin length, 10.3-16.3% of standard length vs. 16.4-22.3% in C. trilobatus and 16.5-23.4% in C. kalambo; a shorter depth at dorsal fin insertion, 14.5-18.4% of standard length vs. 20.0-24.0% in C. trilobatus and 18.2-23.5% in C. kalambo; a shorter caudal peduncle depth, 8.7-12.6% of standard length vs. 11.9-14.5% in C. trilobatus and 11.3-15.4% in C. kalambo; a longer snout length, 20.3-26.2% of standard length vs. mean of 19.9% in C. trilobatus and mean of 18.4% in C. kalambo; a shorter maxillary barbel, 5.0-7.5% of standard length vs. a mean of 10.6% in C. trilobatus and mean of 9.3% in C. kalambo; a wider oral disc, 20.4-26.8% of standard length vs. mean of 19.0% in C. trilobatus and mean of 19.7% in C. kalambo; a wider set of premaxillary tooth plates, 15.6-19.8% of standard length vs. mean of 14.0% in C. trilobatus and mean of 13.7% in C. kalambo; 27-45 primary teeth on each premaxilla, vs. 18-31 in C. trilobatus and 7-21 in C. kalambo; 6 soft rays in the dorsal fin, rarely 5, vs. 5 rays in C. trilobatus and C. kalambo (Ref. 87986). Caudal-fin shape in males of C. igamba is also fairly similar to the shape found in males of C. productus; but in C. productus all caudal-fin rays, especially the middle rays, are elongated and the fin is diamond shaped; Chiloglanis igamba is also easily distinguished from C. productus by its pigmentation, which consists of cream-coloured splotches on a light brown background; in contrast, the pigmentation of C. productus is medium to dark brown with a pale midlateral stripe along the lateral line; Chiloglanis igamba is further distinguished from C. productus by a shorter pectoral spine, 9.9-15.1% of standard length vs. 15.2-18.5%; a shorter pectoral-fin longest ray, 15.2-18.8% of standard length vs. 19.1-23.9%; and a shorter adipose-fin base, 10.3-16.3% of standard length vs. 22.5-26.2% (Ref. 87986). Finally, in Chiloglanis asymetricaudalis the caudal fin of adult males is forked, but with an elongate upper lobe; in addition to caudal fin shape, C. igamba is easily distinguished from C. asymetricaudalis by a shorter pectoral spine, 9.9-15.1% of standard length vs. 16.4-19.7%; a shorter dorsal spine, 8.2-12.7% of standard length vs. 13.0-15.7%; a shorter anal fin, 11.7-15.9% of standard length vs. 22.6-28.0%; a shorter caudal peduncle, 15.0-17.7% of standard length vs. 18.4-20.9%; and a markedly different pigment pattern (Ref. 87986).
Body shape (shape guide): elongated.

This species is most abundant within the Igamba Falls area and associated large rapids, and is much less common in smaller rapids both above and below these falls (Ref. 87986).
