Turkish and German scientists have described new species of shemaya bleak from western Anatolia in Turkey.
The description of the new species, named Alburnus demiri, is published in the latest issue of Ichthyological Exploration of Freshwaters.
Alburnus demiri is distinguished from other members of the genus in having a combination of: anal-fin origin below branched dorsal-fin ray 7"8; 13"14 branched anal-fin rays; 18"21 gill rakers; 43"46+3 lateral line scales; ventral keel exposed for 6"9 scales in front of anus; head length 23"26% standard length, 1.1"1.2 times in body depth at dorsal-fin origin; predorsal length 57"61% standard length; caudal peduncle depth 11% standard length, 1.6"1.9 times in its length; caudal peduncle length 18"20% standard length; eye diameter 6.4"7.2% standard length, 0.97"1.04 times in interorbital distance; body depth at dorsal-fin origin 26"28% standard length; faint, dark lateral stripe on the body and numerous small tubercles in nuptial males.
The new species is named after Muzaffer Demir, in recognition of his work on Turkish benthic invertebrates and marine fishes.
