Munaya River (Cross River tributary) at Akwen Bridge, Cameroon (05�� 45 ' 50 " N; 9 ��03' 39 " E). Specimens deposited. Holotype n�� 37768 and 2 paratypes n�� 37770 RMCA; 2 paratypes n�� HEL 511 MNHN. Etymology. The new species name is dedicated to Dr Djeto of the University of Yaound�� 1, Cameroon, for his technical advice during the manuscript elaboration. Description (based on 10 individuals). Adults 556 (367���658, 9) long. 163 (92���212, 10) wide at level of ovary. Pharynx globular 45 (27���62, 10) in diameter. Long dorsal anchor with guard four times longer than shaft, both thickened, sometimes presence of fenestra, blade regularly curved and not hollow: a = 59 (54���63, 16), b = 41 (36���45, 16), c = 5 (3���11, 16), d = 20 (16���25, 16), e = 11 (9���12, 16). Slightly arched and thick dorsal transverse bar, short auricles: x = 49 (44���58, 9), w = 9 (8���11, 9), y = 18 (14���21, 9), h = 10 (7���13, 17). Ventral anchor not similar to dorsal one, with very short guard and shaft, sometimes presence of numerous fenestra: a = 45 (39���48, 18), b = 42 (38���46, 18), c = 4 (2���5, 18), d = 9 (7���13, 18), e = 12 (10���13, 18). V���shaped ventral transverse bar: x = 55 (49���59, 18), w = 8 (7���10, 9). First marginal hook of medium size, third to seventh marginal hook short: Mh I = 22 (17���25, 18), Mh II = 13 (12���14, 17), Mh III = 22 (19���26, 14), Mh IV = 25 (23���28, 16), Mh V = 24 (22���26, 17), Mh VI = 23 (21���26, 18), Mh VII = 22 (18���25, 18). Tubular, thin and slightly spirally coiled penis (2 turns) starting in a bulb with developed heel: Pe = 41 (39���48, 10), He = 7 (6���9, 10). Accessory piece is a large gutter shaped band, ending in a narrow extremity which is folded back. We did not see a filament linking the AP and the penis: AP = 51 (43���56, 10). Short, arched and funnel shaped vagina: x = 10 (7 + 13, 10), w = 2 (2���3, 10). Remarks. This new species resembles its seven congeners already described from Tylochromis Regan 1920 host species (see above and C. chrysopiformis n. sp.) in having small auricles of the dorsal transverse bar (described as ���two small, hollow outgrowths on the anterior convex face��� by Pariselle & Euzet 1994), a spirally coiled penis and an accessory piece apparently not connected to the base of the penis (except for C. sigmocirrus n. sp. and C. chrysopiformis n. sp.). Cichlidogyrus djietoi n. sp. resembles C. kothiasi, C. muzumanii and C. chrysopiformis n. sp. in having marginal hook pair I more developed (22 ��m, 20.6 ��m, 24 ��m and 25 ��m, respectively), while C. sigmocirrus n. sp., C. pouyaudi, C. berrebii and C. mulimbwai have Mh I of small size (14 ��m, 12.3 ��m, 13.1 ��m and 15 ��m, respectively). By the shape of the penis and that of the accessory piece C. djietoi n. sp. is easily distinguishable from C. mulimbwai: developed (7 ��m) heel and thin short penis (41 ��m), large AP (51 ��m) vs. square heel (5 ��m) and long and thick penis (63 ��m), reduced (19 ��m) AP, respectively. Cichlidogyrus djietoi n. sp. resembles C. kothiasi by the shape of the penis and that of the accessory piece; their main differences are the dimension of sclerotized pieces, always larger in C. djietoi n. sp.: e.g. penis 41 ��m vs. 29 ��m, AP 51 ��m vs. 31 ��m, dorsal anchor length 59 ��m vs. 50 ��m, etc.; and the presence of a sclerotized vagina in C. djietoi n. sp. (vs. absence). Cichlidogyrus djietoi n. sp. resembles C. chrysopiformis n. sp. by the shape of the penis (except for that of the heel: cylindrical vs. flared) and of the accessory piece (extremities are of different shape: folded back vs. ending in three protuberances). The main differences are the dimension of sclerotized pieces of the haptor, always larger in C. djietoi n. sp. [e.g. dorsal anchor length 59 ��m vs. 50 ��m, ventral anchor length 45 ��m vs. 39 ��m, dorsal bar length 49 ��m vs. 41 ��m, etc.], and the shape of the vagina (funnel shaped in C. djietoi n. sp. vs. cylindrical in C. chrysopiformis n. sp.)., Published as part of Pariselle, Antoine, Bitja Nyom, Arnold R. & Bilong Bilong, Charles F., 2014, Four new species of Cichlidogyrus (Monogenea, Ancyrocephalidae) from Sarotherodon mvogoi and Tylochromis sudanensis (Teleostei, Cichlidae) in Cameroon, pp. 258-266 in Zootaxa 3881 (3) on page 263, DOI: 10.11646/zootaxa.3881.3.4, http://zenodo.org/record/229946, {"references":["Pariselle, A. & Euzet, L.

First and third to seventh marginal hook short: Mh I = 14 �� 0.5 (13���16, 39), Mh II = 12 �� 0.7 (10���13, 30), Mh III = 20 �� 1.1 (17���22, 34), Mh IV = 23 �� 0.9 (21���25, 35), Mh V = 24 �� 1 (21���26, 39), Mh VI = 22 �� 0.9 (20���25, 39), Mh VII = 21 �� 1 (18���23, 36). Tubular sinuous (slightly spirally coiled) penis starting in a bulb with reduced heel, accessory piece is a spirally coiled (1.5 turn) band wrapped round the penis and attached to the penis basal bulb by a very thin filament: Pe = 54 (49���60, 20), He = 2 (2���3, 20), AP = 44 (36���54, 20). No visible vagina. Remarks. This new species resembles its five congeners already described from species of Tylochromis Regan, 1920 [i.e. Cichlidogyrus berrebii Pariselle & Euzet, 1994; Cichlidogyrus kothiasi Pariselle & Euzet, 1994; Cichlidogyrus pouyaudi Pariselle & Euzet, 1994; Cichlidogyrus mulimbwai Muterezi Bukinga, Vanhove, Van Steenberge & Pariselle, 2012 and Cichlidogyrus muzumanii Muterezi Bukinga, Vanhove, Van Steenberge & Pariselle, 2012]; in having small auricles of the dorsal transverse bar (described as ���two small, hollow outgrowths on the anterior convex face��� by Pariselle & Euzet 1994). Its penis is not clearly spirally coiled and its accessory piece seems to be linked to the basal bulb of the penis by a thin filament, these features have not been mentioned for the other species harboured by Tylochromis spp., but they are hardly discernible. Cichlidogyrus sigmocirrus n. sp. resembles C. pouyaudi, C. berrebii, C. mulimbwai in having marginal hook I of small size (14 ��m, 12.3 ��m, 13.1 ��m and 15 ��m, respectively), while C. kothiasi and C. muzumanii have a more developed marginal hook pair I (20.6 ��m and 24 ��m, respectively). By the shape of the penis C. sigmocirrus n. sp. is easily distinguishable from C. mulimbwai: reduced heel (2 ��m) and 41 ��m long vs. developed heel (9 ��m) and 54 ��m, respectively. By the shape of the penis and that of the accessory piece (AP) C. sigmocirrus n. sp. is easily distinguishable from C. berrebii: reduced heel and AP a large ribbon vs. developed heel (massive) and AP a thinner ribbon, respectively, and from C. pouyaudi: reduced heel and smooth ending of AP vs. long heel and thickened AP with ending forming a beak, respectively., Published as part of Pariselle, Antoine, Bitja Nyom, Arnold R. & Bilong Bilong, Charles F., 2014, Four new species of Cichlidogyrus (Monogenea, Ancyrocephalidae) from Sarotherodon mvogoi and Tylochromis sudanensis (Teleostei, Cichlidae) in Cameroon, pp. 258-266 in Zootaxa 3881 (3) on page 261, DOI: 10.11646/zootaxa.3881.3.4, http://zenodo.org/record/229946, {"references":["Pariselle, A. & Euzet, L.

Remarks: Considering the morphology of the U 1 of small size, and U III to U VII long, of the MCC (penis with perpendicular and large proximal bulb, S-shaped accessory piece without associated auxiliary plate), and the presence of a sclerotised vagina, C. gillesi n. sp. resembles Cichlidogyrus anthemocolpos Dossou, 1982; Cichlidogyrus bonhommei Pariselle & Euzet, 1998; Cichlidogyrus bouvii Pariselle & Euzet, 1997; Cichlidogyrus dossoui Dou��llou, 1993; Cichlidogyrus douellouae Pariselle, Bilong Bilong & Euzet, 2003; Cichlidogyrus ergensi Dossou, 1982; Cichlidogyrus flexicolpos Pariselle & Euzet, 1995; Cichlidogyrus hemi Pariselle & Euzet, 1998; Cichlidogyrus kouassii N���Douba, Thys van den Audenaerde & Pariselle, 1997; Cichlidogyrus legendrei Pariselle & Euzet, 2003; Cichlidogyrus lemoallei Pariselle & Euzet, 2003; Cichlidogyrus ouedraogoi Pariselle & Euzet, 1996; Cichlidogyrus tiberianus and Cichlidogyrus vexus Pariselle & Euzet, 1995. The new species could be distinguished from all these others by the size and shape of the heel of the penis (large, trapezoid) and as well as that of the vagina (S-shaped, large and wrinkle walled)., Published as part of Pariselle, Antoine, Bitja Nyom, Arnold R. & Bilong Bilong, Charles F., 2013, Checklist of the ancyrocephalids (Monogenea) parasitizing Tilapia species in Cameroon, with the description of three new species in Zootaxa 3599 (1), DOI: 10.5281/zenodo.221201, {"references":["Dossou, C.

International audience; A checklist of the 23 species of Ancyrocephalidae (Monogenea) parasitizing Tilapia species sampled from both sides of the Cameroon Volcanic Line is provided. As already reported elsewhere, Cichlidogyrus aegypticus in Cameroon shows two different shape of its vagina, and C. tilapiae, C. arthracanthus and C. tiberianus were found on a wide range of host species. Among the 23 studied species of Monogenea, three are considered new species and are described herein: Cichlidogyrus berminensis n. sp. from Tilapia bemini, characterized by a short penis with marked narrow heel, a simple and straight accessory piece ending in a large hook, and a medium sized pair of uncinuli I; Cichlidogyrus gillesi n. sp. from Tilapia guineensis, characterized by a large and trapezoid heel of the penis and a S-shaped and wrinkle walled vagina; and Scutogyrus vanhovei n. sp. from Tilapia mariae, characterized by the presence of a distinct swollen portion of the penis. From a parasite's point of view, the CVL has no influence on species dispersion/distribution.
