Taxonomic Remarks
Crossocheilus siamensis: The species name has been applied to several species described or undescribed, and will be synonymized in the next update. It is either Garra cambodgiensis (Tirant, 1883), Crossocheilus atrilimes Kottelat, 2000, Crossocheilus langei Bleeker, 1860, or an undescribed lemon-finned Crossocheilus (Josef Niederle, pers. comm., 18/09/08).

A binom misapplied to several species, and the information contained in fishbase belongs to several species too. The main reference in fishbase is Kottelat, 1998. Nevertheless, Kottelat later changed his opinion and described the fishes from Mekong basin he originaly
called Crossocheilus siamensis as Crossocheilus atrilimes. Cf. Kottelat, M., 2000 Ref. 36949. Hence the reference is to Crossocheilus atrilimes in reality. Ref. 12693 refers to Crossocheilus atrilimes too and probably to the following species in reality. There is no reference to the genuine Epalzeorhynchos siamensis alias Crossocheilus siamensis except Smith, 1931
and Smith, 1945. Another formally undescribed species similar to Crossocheilus
atrilimes occurs in the Mekong basin in southern Laos. It is twice larger and has lemon-yellow fin colour instead of the sandy yellow in Crossocheilus atrilimes. It possesses small maxillary barbels. The image Crsia_u1.jpg belongs probably to it. It is difficult to distinguish images of Crossocheilus atrilimes and the lemon-finned Crossocheilus because the colours are not faithful. Smith, 1931 correctly described the lateral stripe as beginning at the opercle in Crossocheilus siamensis. It may be checked on the image of the holotype at
http://math.muni.cz/~niederle/crossocheilus_siamensis_page.html
Further, it has a nearly V-shaped furrowed upper lip. The information should be contained in morphology. The Crossocheilus siamensis of the aquarium trade is either Garra cambodgiensis, or Crossocheilus atrilimes, or the lemon-finned Crossocheilus mentioned above, or Crossocheilus langei, to which the images Crsia_u0.jpg, Crsia_u2.jpg and
Crsia_u3.jpg belong. The first species is completely different, in the remaining three the lateral stripe begins at the snout. The genuine red-algae eater is Crossocheilus langei.
