Abstract
- Two types of the karyomorphs in the katydid Mecopoda elongata (L.) from Borneo (Malaysia) and Amami Is. (Japan) were found. The chromosomal comple- ment of M. elongata from Amami Is. and one karyomorph from Borneo (Kota Kinabalu - song 1) consists of 28 autosomes plus the X in the male (2n=29). In two long pairs, pair L1 is metacentric, whereas pair L2 is subacrocentric. Other autosomes are meta or submetacentric. The size and shape of the X chromosome is similar to the L1 pair. "Kota Kinabalu - song-2" karyomorph has the same chromosome num- ber as "KK song-1" and "Amami". However, in "KK song-2" the autosomes belong- ing to L2 pair are metacentric. The size of these chromosomes is approximately sim- ilar to the L1 pair and the X chromosome. The discrete chromosome differentiation in M. elongata suggest that this species consists of several biological species. In M. elongata from Borneo, the assumption of a belonging of two groups of the kary- omorphs to different species proves to be true also in differences in crepitating.
