Dogielius clavipenis Guégan, Lambert & Euzet, 1989

(Figure 15)

Type host and locality: Labeo coubie, Niger River (Bamako), Mali.

Other record: Labeo coubie, Baoulé River (Missira), Mali (Guégan et al. 1989).

Present records: Labeo coubie, Gambia River near the hotel Simenti (sand beach 13° 01.543’N; 13º 17.471’W, gravel beach 13º 01.395’N; 13º 17.350’W), Mare de Simenti (13º 01.790’N; 13º 17.608’W), Gambia River near the Campement du Lion (13º 01.493’N; 13º 14.491’W), Niokolo-Koba National Park, Senegal.

Site: Gill lamellae.

Type specimens: Holotype MNHN HC 270.

Material examined: 9 unflattened and 11 flattened specimens in GAP.

Description: Body length 430 (360–496; n = 8); greatest width 114 (95–136; n = 9) usually near midlength. Haptor 97 (71–115; n = 7) long, 191 (178–223; n = 7) wide. Single pair of anchors (ventral): inner length 38 (35–39; n = 9); outer length 40 (38–42; n = 9); point length 29 (27–33; n = 9). One bar (ventral): 62 (57–65; n = 11) long, 10 (9–11; n = 11) wide. Hooks 7 pairs, slightly dissimilar in size; hook lengths (n = 10): pairs I, VI, VII = 20 (18–22); pair II = 23 (21–25); pairs III, IV = 22 (19–24); pair V = 21 (20–22). Needles (1 pair) located near hooks of pair V. Vagina sclerotized, 24 (19–28; n = 5) long. Copulatory organ composed of a relatively straight tube and articulated accessory piece; total length 41 (38–45; n = 10); tube trace-length 35 (34–36; n = 10).

Remarks: The present material corresponds in morphometrical characteristrics to that described originally on the same host from Mali (Guégan et al. 1989).
