    Note on the banded karyotype of the enigmatic South Asian loach Vaillantella maassi (Cypriniformes: Vaillantellidae)

  • Original language description

    The karyotype of Vaillantella maassi, a loach with an unusually long dorsal fin, was investigated using sequentialCMA3 and AgNO3 staining to test if this character evolved in parallel with Vaillantella's morphological distinctness. The karyotype was 2n =50 with 13 pairs of metacentric-submetacentric and 12 pairs of subtelocentric chromosomes. Sequential CMA3 banding and AgNO3 staining evidenced NORs in the short arms of pair no. 2. Additional CMA3-positive, Ag-negative signals were present in the shortarms of pairs 14 and 15. The karyotype paralleled those of most other cobitoid loaches studied so far and is apparently not associated with the morphological distinctness of Vaillantella.

    Poznámka o diferencovaně barveném karyotypu záhadné jihosijské sekavcovité ryby, Vaillantella maassi (Cypriniformes: Vaillantellidae)

  • Czech description

    Byl vyšetřen karyotyp záhadné a velmi málo známé jihoasijské sekavcovité ryby s neobvykle dlouhou hřbetní ploutví, Vaillantella maassi, pomocí několika typů barvení chromozómů. Karyotyp s diploidním počtem chromozómů 2n = 50 byl obdobný jako u ostatníchsekavcovitých a nepotvrdila se hypotéza, že morfologická odlišnost souvisí i se změnami tohoto znaku.
