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).
Eponymy: Paul De Kimpe (d: 1927) was the Fisheries Officer at Cotonou, Dahomey (now Republic of Benin). [...] (Ref. 128868), visit book page.

; agua dulce; salobre pelágico. Tropical; 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.
Longitud en la primera madurez / Tamaño / Peso / Edad
Madurez: Lm 3.8, range 4 - 4 cm
Max length : 5.5 cm TL macho / no sexado; (Ref. 130826)
Espinas dorsales (total) : 0; Radios blandos dorsales (total) : 14 - 16; Espinas anales: 0; Radios blandos anales: 17 - 20; Vértebra: 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).
Body shape (shape guide): fusiform / normal; Cross section: oval.
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).
