Fundulopanchax kamdemi

description

Description. See Figures 2 – 4 for general appearance and Table 1 for morphometric data of the type specimens. Fundulopanchax of large size. Dorsal-fin origin distinctly behind mid-length of body and just behind anal fin origin. Dorsal fin 15 – 18 rays, anal fin 16 – 19 rays. Scales on mid-longitudinal series 34 – 38 plus 3 or 4 on caudal fin base, most with shallow pit in centre, not connected to underlying neuromast system. Transverse rows of scales above pelvic fin 10 – 11; scale rows around caudal peduncle 16. Supra-orbital squamation Gpattern, with two H-scales. Anterior and central cephalic neuromast systems separated, consisting of two shallow grooves, lined with low lobes. Posterior cephalic neuromast system, consisting of 3 neuromasts, in an open curved groove, with both ends angled to approximately 90 º. Preopercular neuromast system tubular with six exposing pores. holotype Paratype males X (n = 13) SD Paratype females X (n = 13) SD male (range) (range) Standard length 50.0 43.5 – 73.0 40.0 – 61.7 Interorbital width 12.2 7.4 – 12.7 11.9 0.76 7.6 – 12.7 11.5 0.66 Snout length 5.2 5.8 – 8.3 7.1 0.92 5.2 – 8.7 7.1 1.22 Males.

diagnosis

Diagnosis. Fundulopanchax kamdemi shares with all other Fundulopanchax species except those of the subgenus Paludopanchax 16 or more scales around the caudal peduncle versus 12 in Aphyosemion s. l. It is distinguished from all Aphyosemion species and many Fundulopanchax except F. arnoldi, F. deltaensis, F. g u l a r i s, F. kribianus, F. ndianus, F. robertsoni, F. rubrolabialis, F. schwoiseri, F. s j o e s t e d t i, and F. w a l k e r i by the high number of dorsal (15 – 18) and anal fin rays (16 – 19) (according to the descriptions and data in Huber 2000). It is distinguished from all Fundulopanchax species by its unique male coloration of a red longitudinal band on the middle of the sides versus no red band, with the exception of F. amieti, F. avichang, F. deltaensis and some individual specimens of F. ndianus, F. p u e r z l i and F. spoorenbergi. It is distinguished from all Fundulopanchax species, except F. ndianus and some specimens of F. p u e r z l i, by a red ventral band from the pelvic fins to the lower caudal fin base. F. kamdemi is distinguished from the latter species and most other Fundulopanchax except F. spoorenbergi by the coloration of the unpaired fins as given

distribution

Distribution. Fundulopanchax kamdemi is known from a limited number of localities, all within the Korup National Park. It was mentioned as Aphyosemion sp. 0 1 (cf. A. cameronense) in McGregor Reid (1989) from the Akpa-Yafe River and the upper Ndian River, in southern Korup only. This was confirmed by comparing the specimens, deposited by Kamdem Toham, as Aphyosemion sp. (KORUP 01) in the collection of the Museum for Central Africa, Tervuren, Belgium. He found them in the swampy parts that edge the small creeks under the cover of the forest in the southern Korup close to the Science camp (Kamdem Toham, 1992). Additionally the three collection localities, studied by the first author, confirmed the presence of the new species in the southern part of the Park only. Presence in the adjacent Oban National Park at the Nigerian side of the border may be possible but could not be confirmed as no collections of cyprinodontiform fishes are known from there. Other cyprinodontiform species found in sympatry with F. kamdemi are F. marmoratus, Epiplatys infrafasciatus (Günther, 1866) (= E. sexfasciatus in McGregor Reid, 1989 and Kamdem Toham, 1992), Aphyosemion (Chromaphyosemion) bivittatum, A. c
