Auchenoglanididae (Flatnose catfishes)
Etymology: Notoglanidium: Greek, noton = back + Greek, glanis = a fish that can eat the bait without touching the hook; a cat fish; diminutive (Ref. 45335); thomasi: Named in honour of N.W. Thomas, collector of the type specimens (Ref. 94168).
Eponymy: Northcote Whitridge Thomas (1868–1936) was a British Government anthropologist who conducted field research in Nigeria (1909–1913) and Sierra Leone (1914–1915) particularly among the Edo, Yoruba, Kukuruku, Esa and Igbo people. [...] (Ref. 128868), visit book page.

Size / Вес / Возраст
половая зрелость: Lm ? range ? - ? cm
Max length : 4.4 cm SL самец/пол неопределен; (Ref. 94168)
членистые (мягкие) лучи спинного плавника (общее число) : 12 - 16; колючие лучи анального плавника: 0; членистые (мягкие) лучи анального плавника: 9 - 12; позвонки: 34. Diagnosis: Notoglanidium thomasi differs from all congeners in the large interorbital distance, 41.0-46.7% of head length vs. less than 37% in all other species (Ref. 94168). It differs from other species in the genus in having: a rather large eye diameter, 9.1-12.5% of head length vs. smaller in N. depierrei, N. maculatum and N. pallidum; a small combined premaxillary tooth plate width, 11.9-18.2% of head length vs. larger in N. akiri, N. boutchangai, N. macrostoma and N. pembetadi; and a relatively large number of soft dorsal-fin rays, 12-16 vs. less in N. akiri, N. boutchangai, N. depierrei and N. macrostoma (Ref. 94168).
Body shape (shape guide): elongated.
