Analysis of the karyotypes of four species of the Leptynia attenuata complex (Insecta Phasmatodea)

SUMMARY

Karyotypes of several bisexual populations of the Leptynia attenuata complex were analysed. This complex includes four karyotypically differentiated taxa: Leptynia attenuata s.str., Leptynia montana, Leptynia caprai and Leptynia sp. The chromosome numbers of the four species are: 2n=36 (♂ XY; ♀ XX) for Leptynia attenuata, 2n=38 (♂ X0; ♀ XX) for Leptynia montana, 2n=40 (♂ X0; ♀ XX) for Leptynia caprai and 2n=40 (♂ X0; ♀ XX) for Leptynia sp. The evolutionary relationships between the four species are discussed.
