Gymnostomus horai ( Banarescu, 1986)

Banarescu (1986: 153) considered C. burmanicus Hora, 1936 , to be a nomen nudum. This is erroneous as, as discussed above, the name is available by indication. Banarescu (1986) described C. horai , a species from the Salween basin, of which he was not sure whether it is the same species as the one recorded by Mukerji and Hora. A comparison of the figures of C. horai and Mukerji’s (1934) figure 6 immediately suggests they are different species and, in fact, Roberts (1997: 191) considered C. horai to be a species of Cirrhinus . As the name Cirrhinus horai has already been used by Lakshmanan (1966: 59), Roberts (1997) proposed Cirrhinus lu as a replacement name.

Cirrhinus sensu Roberts (1997) is not accepted as valid by several authors, who still recognise Cirrhinus only for the species with, among others, 10-15 branched dorsal rays and Henicorhynchus for species with 8-9 (e.g., Kottelat, 1998, 2001) (this is based on Southeast Asian species and Henicorhynchus may or may not include the South Asian species with short dorsal fin). Under this system, C. horai Lakshmanan, 1966 , is a real Cirrhinus (in fact a junior subjective synonym of C. cirrhosus ( Bloch, 1795) ; Roberts, 1997) and Crossocheilus horai Banarescu, 1986 , is a species of Henicorhynchus , and the name is valid (ICZN article 59.4).

If the synonymies in Roberts (1997) are correct, and if all ‘ Cirrhinus’ with a short dorsal fin are congeneric, then the correct generic name for this genus should be Gymnostomus Heckel (1843: 1030) as this is a senior subjective synonym of Henicorhynchus Smith (1945: 256 ; type species: Henicorhynchus lobatus Smith, 1945: 257 , by original designation). The type species of Gymnostomus is Cyprinus ariza Buchanan, 1807 (p. 344, pl. 30) by subsequent designation by Bleeker (1863: 197).
