Abstract

Remarks on the Collection of Cyprinodontiformes (Pisces: Teleostei) of the Zoological Museum, Berlin. I. The Genera Aphyosemion Myers, 1924 and Fundulosoma Ahl, 1924. Part 1 This paper is the first part of a revision of the type specimens of the Cyprinodontiformes sensu PARENTI (1981) of the ichthyological collection of the Zoological Museum Berlin including most species of the genus Aphyosemion MYERS, 1924 as we understand these species and its synonyms nowadays.

On the taxonomic identity of Fundulus beauforti Ahl, 1924 (Cyprinodontiformes, Aplocheiloidei)

“…However, Seegers (1988) provided counts different not only from those of Ahl (1924a) but also from Holly's (1930) counts (D 12, A 14;Seegers 1988: 12), and stated, without providing details, that the holotype has a more posterior dorsalfin position than known for R. batesii. Subsequent authors followed Seegers (1986Seegers ( , 1988 in his conclusions (e.g. Huber 2007;Lazara 2001;Wildekamp 1993).…”

“…1) and the distinguishing characters are not easily accessible. This led to two different opinions about the taxonomic identity (Holly 1930;Huber 2007;Scheel 1968Scheel , 1990Seegers 1986Seegers , 1988Wildekamp 1993). Holly (1930: 209), in his revision of the freshwater fishes of Cameroon, corrected some of the counts given by Ahl (1924a) and assumed a closer relationship to Fundulus gularis Boulenger, 1902 andF.…”

“…From the same locality and collection Ahl also described five additional species in a total of four different publications: F. gustavi Ahl, 1924a, Panchax loboanus and P. bellicauda, both Ahl, 1924b, P. sangmelinensis Ahl, 1928, and finally Aphyosemion (Fundulopanchax) schreineri Ahl, 1935. However, from the area near Sangmelima, including the upper Lobo river, currently only four nothobranchiid species are known, which are: Mesoaphyosemion cameronense (Boulenger, 1903), Kathetys exiguum (Boulenger, 1911), Raddaella batesii (Boulenger, 1911), and Epiplatys sangmelinensis (Ahl, 1928) (Scheel 1968;Seegers 1986Seegers , 1988Wildekamp 1993Wildekamp , 1996. Only one of Ahl's species, E. sangmelinensis, is currently accepted as valid, the remaining species are considered as synonyms of M. cameronense (for P. bellicauda), K. exiguum (for P. loboanus) or R. batesii [for F. gustavi, A.…”

“…(Fp. ) schreineri] by different authors (Holly 1930;Huber 2007;Paepke & Seegers 1986;Scheel 1968Scheel , 1990Seegers 1986Seegers , 1988Wildekamp 1993Wildekamp , 1996 with the exception of F. beauforti, which was either considered as synonym to M. cameronense (Huber 2007;Seegers 1986Seegers , 1988Wildekamp 1993), or related (e.g. Holly 1930 or synonymous to R. batesii (Scheel 1968(Scheel , 1990.…”

“…Holly 1930 or synonymous to R. batesii (Scheel 1968(Scheel , 1990. Usually both species are easily distinguished by colour pattern of males, number of dorsal-fin rays and position of dorsal-relative to anal-fin (Amiet 1987;Huber 2007;Seegers 1986Seegers , 1988Wildekamp 1993Wildekamp , 1996. Values of dorsal-and anal-fin rays in the literature for Raddaella batesii are for dorsal-fin 14-17 rays, anal-fin 14-18 rays, and first dorsal-fin ray above first to fifth anal-fin ray, the values for Mesoaphyosemion species are for the dorsal-fin 10-14 rays, for the anal-fin 14-18 rays, and the first dorsal-fin ray above the sixth to ninth anal-fin ray (Amiet 1987;Boulenger 1911;Huber 2007, Seegers 1986, 1988Van der Zee et al 2007;Wildekamp 1993Wildekamp , 1996.…”
