Etymology: Laeviscutella: Latin, laevis = flat + Latin, scutum, scutella, diminutive = shield (Ref. 45335); dekimpei: Named in honour of M.P. De Kimpe, Ing. Eaux et Forêts, Gx., Fisheries Officer at Cotonou (Dahomey) for his services in collecting this and other species for the Musée Royal de l'Afrique Centrale in Tervuren (Ref. 42928).

Africa: lower parts of rivers and lagoons in West Africa (Ref. 188), from the Casamance River to the Niger delta (Ref. 2849, 28136, 81269), lower Ogowe River in Gabon (Ref. 81631) and Loémé River in Republic of Congo (Ref. 81631). Also reported to occur in the Congo River (Ref. 188, 28136), but this needs confirmation.
Length at first maturity / 大小 / 重量 / 年齡
Maturity: Lm 3.8, range 4 - 4 cm
Max length : 4.6 cm SL 雄魚/尚未辨別雌雄; (Ref. 81631)
背棘 (總數): 0; 背的軟條 (總數): 14-16; 臀棘 0; 臀鰭軟條: 17 - 20; 脊椎骨: 39 - 42. Diagnosis: Laeviscutella dekimpei is distinguished by its congeners by the following characters: belly rounded, prepelvic scutes 7 or 8, with lateral arms but without keels and hidden by scales; postpelvic scutes without arms, but supporting a low membranous keel; lower gillrakers 21 to 26 (Ref. 188, 81269, 81631). In all other West African pellonulines with scutes, the postpelvic scutes have lateral arms, except Sierrathrissa, in which the prepelvic scutes also lack arms and the pelvic fin insertion is well before the dorsal fin origin (Ref. 188, 81631).
A riverine species, chiefly near the coast and entering lagoons, where salinities vary with the tides; it is presumably euryhaline, although it may escape high salinities (Ref. 188). Ripe females of 3.5 to 4.0 cm standard length were recorded in Ebrié Lagoon (Ref. 188, 1989).
