Etymology: Laeviscutella: Latin, laevis = flat + Latin, scutum, scutella, diminutive = shield (Ref. 45335); dekimpei: Named in honour of M.P. De Kimpe, Ing.

生态学
; 淡水; 半咸淡水 大洋性. 熱帶; 10°N - 7°S, 6°W - 15°E (Ref. 188)
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.
非洲: 在潟湖中的河川下游 (卡薩芒斯在塞內加爾到剛果)(參考文獻 28136)(湖 Ebrie, 象牙海岸; 湖 Nokue, 貝南). 也記錄自尼日。 (參考文獻 2849)
Length at first maturity / 大小 / 重量 / 年龄
Maturity: Lm 3.8, range 4 - 4 cm
Max length : 4.6 cm SL 雄鱼/尚未辨别雌雄; (Ref. 81631)
背棘 (总数): 0; 背的软条 (总数): 14-16; 臀棘 0; 臀鳍软条: 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).
可能不超过大约 4 公分标准长度。 前腹鳍鳞甲 7 或 8, 与侧部武装但是没有龙骨脊而且藏在了鳞片; 没有手臂的在腹鳍之后的鳞甲, 但是支撑一个低的膜状龙骨脊。 用鳞甲与所有的其他西非 pellonulines 区分了,藉由缺少侧部武装在它的在腹鳍之后的鳞甲, 除了 Sierrathrissa 以外 , 前腹鳍鳞甲缺乏手臂。
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).
出现于河, 主要地在海岸的附近而且进入泻湖, 在哪里盐度改变随着潮水。 此鱼种是可能广盐性, 虽然它可能逃脱高的盐度。 3.5 到 4 公分 SL 的成熟雌性在湖 Ebrie 被记录。
