Some aspects of karyotype of Liarina (Orthoptera: Tettigoniidae, Agraeciini) from Vietnam
Languages of publication
Karyotypes (chromosome number and shape) of four species of the subtribe Liarina were studied. The chromosome numbers and NF (Fundamental Number) in this group of species range from 2n%=33 (34) to 27(30): Liaromorpha buonluoiensis 2n%=33 (34), Sialaiana transiens 2n%=29 (34), Liara tramlapensis 2n%=29 (32), and Anelytra (Perianelytra) propria 2n%=27 (30). Cyto-taxonomy analysis indicates an intensive karyotype evolution among species belonging to three different groups of the genera. Differences of karyotypes are connected with Robertsonian fusion and tandem fusion in autosomes. Additionally, C-banding distribution and location of the NORs were studied.
