Phoxinellus pseudalepidotus (Teleostei: cyprinidae), a new species from the Neretva basin with an overview of the morphology of Phoxinellus species of Croatia and Bosnia-Herzegovina

摘要

Phoxinellus pseudalepidotus, new species, from the Neretva basin differs in having the unique combination of characters: both dorsal and anal fins with 7(1/2) branched rays, V-A distance 73-80 percent of P-V distance, mouth subterminal, pharyngeal teeth 5-4, body scaleless besides lateral line scales and several scales above and below lateral line behind head, lateral line usually with 54-77 scales, terminating on caudal peduncle posterior to anal-fin base, postcleithrum commonly absent. The morphology of Phoxinellus species is reviewed. The ten examined species are divided into two groups. Group 1 includes species with plain coloration, a stripe from the head to the caudal peduncle, postcleithrum small or absent, no genital papilla, body naked (P. alepidotus, P. dalmaticus, P. pseudalepidotus) or with scales (P. croaticns, P. fontinalis, P. metohiensis). Group 2 includes species with irregularly spotted color pattern, a large postcleithrum, an increased number of precaudal anal-fin pterygiophores and a large genital papilla in females (P. adspersus, P. ghetaldii, P. jadovensis, P. krbavensis).
