Abstract
The diploid number ofO. roylei is 62. The resulting karyotype morphology suggests the inclusion ofO. roylei, together withO. rufescens, O. macrotis andO. rutila, in the 2nd cytotaxonomic group of Vorontsov and Ivanitskaya, 1973. This grouping also meets systematic and biogeographic considerations.
Riassunto
I cromosomi di Ochotona roylei (Mammalia, Lagomorpha). Sono stati studiati i cromosomi diOchotona roylei (Ogilby, 1839) su metafasi somatiche utilizzando sia procedure di colorazione standard, sia tecniche di bandeggio G, C e NOR. Il numero diplode della specie è 62. La morfologia del cariotipo ed il disegno del bandeggio permette di collocare O. roylei nel gruppo citotassonomico II di Vorontsov e Ivanitskaya, 1973, assieme aO. rufescens, O. rutila eO. macrotis. Tale raggruppamento si accorda bene anche con considerazioni tassonomiche tradizionali e biogeografiche.
