Yasuhikotakia Nalbant
Yasuhikotakia Nalbant, 2002
(type species:
Botia modesta Bleeker, 1865
, by original designation). Gender feminine.
Diagnosis. Distinguished from the other genera within the subfamily Botiinae by the following combination of characters: Mental lobe not developed in a barbel, with a pair of fleshy papillae at its anterior edge. Fronto-parietal fontanelle large, wide. Anterior chamber of gas bladder partly covered by bony capsule; posterior chamber large. Top of supraethmoid narrow. Optic foramen small. Anterior process of premaxilla entire, not surrounding a cavity; rostral process rather long, with a more or less distinct ridge along inner edge. Suborbital spine strongly curved backwards, bifid. Head naked (based on Taki, 1972: 74, 76). Colour pattern: most species with pale body and more or less distinct blotch at end of caudal peduncle; a few species with stripes along flank or back; most species with ontogenic changes in colour pattern, usually a vertical pattern in juveniles which disappear with growth.
