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).

生態學
; 淡水; 半鹹淡水 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.

Length at first maturity / 大小 / 重量 / 年齡
Maturity: Lm 3.8, range 4 - 4 cm
Max length : 5.5 cm TL 雄魚/尚未辨別雌雄; (Ref. 130826)
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).
可能不超過大約 4 公分標準長度。 前腹鰭鱗甲 7 或 8, 與側部武裝但是沒有龍骨脊而且藏在了鱗片; 沒有手臂的在腹鰭之後的鱗甲, 但是支撐一個低的膜狀龍骨脊。 用鱗甲與所有的其他西非 pellonulines 區分了,藉由缺少側部武裝在它的在腹鰭之後的鱗甲, 除了 Sierrathrissa 以外 , 前腹鰭鱗甲缺乏手臂。
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).
出現於河, 主要地在海岸的附近而且進入潟湖, 在哪裡鹽度改變隨著潮水。 此魚種是可能廣鹽性, 雖然它可能逃脫高的鹽度。 3.5 到 4 公分 SL 的成熟雌性在湖 Ebrie 被記錄。
