Botia Gray   ZBK

Botia Gray, 1831   ZBK (type species: Botia almorhae Gray, 1831   ZBK , by monotypy). Gender feminine.

Hymenphysa M'Clelland, 1839   ZBK (type species: Cobitis dario Hamilton, 1822   ZBK , by subsequent designation by Jordan, 1919a). Gender feminine.

Diacantha Swainson, 1839   ZBK (type species: Diacantha zebra Swainson, 1839   ZBK , by subsequent designation by Swain, 1883; spelled Diacanthus p. 190, first reviser [Eschmeyer, 1990: 123] retained Diacantha   ZBK as correct original spelling). Gender feminine. [Eschmeyer considered D. zebra   ZBK as type by monotypy; in fact Swainson originally included two species, D. zebra   ZBK and D. flavicauda   ZBK ]

Hymenophysa Bleeker, 1859 (incorrect subsequent spelling of Hymenphysa M'Clelland, 1839   ZBK )

Diagnosis. Distinguished from other genera within the subfamily Botiinae by the following combination of characters: Mental lobe developed in a barbel. Fronto-parietal fontanelle narrow. Anterior chamber of gas bladder almost entirely covered by bony capsule; posterior chamber large or rather reduced. Anterior process of premaxilla entire, not surrounding a cavity; rostral process rather long, with a more or less distinct ridge along inner edge. Top of supraethmoid narrow or broad. Optic foramen very small. Suborbital spine not strongly curved backwards (based on Taki, 1972: 74, 76). Suborbital spine bifid. Head naked.

Remarks. The spelling Hymenophysa used by Fang (1936), Nalbant (1963, 2002), Taki (1972) and others is not correct. The correct original spelling used by M'Clelland (1839: 443) is Hymenphysa   ZBK . Hymenophysa of Bleeker (1859: 303) is an incorrect subsequent spelling of Hymenphysa M'Clelland, 1839   ZBK . Authors (e.g. Nalbant, 1963: 359, 2002: 317) often list Cobitis hymenophysa Bleeker, 1852   ZBK as type species of Hymenphysa   ZBK by tautonymy. As the generic name predates the specific name by 13 years, this of course cannot be the case. In the original description of Hymenphysa   ZBK , only three species are listed ( C. dario   ZBK , C. geto   ZBK , C. grandis ) and the type species has to be selected among them. The earliest valid type species designation is by Jordan (1919a: 195) who designated C. dario   ZBK . Botia dario is placed in Botia s.s.   ZBK by Nalbant (1963, 2002), Taki (1972) and others, and therefore Hymenphysa   ZBK is a junior subjective synonym of Botia   ZBK .

The valid name for the lineage called Hymenophysa by Fang, Nalbant, Taki and others is Syncrossus Blyth, 1860   ZBK .
