D. Lachowska et al., A CYTOGENETIC STUDY ON 8 BEETLE SPECIES (COLEOPTERA, CARABIDAE, SCARABAEIDAE, CERAMBYCIDAE, CHRYSOMELIDAE) FROM CENTRAL-EUROPE, Folia Biologica, 44(3-4), 1996, pp. 99-103
Karyotypic details were studied in males of eight beetle species from
four families, viz. Carabidae: Elaphrus cupreus Duft. (2n=33, n=16+X),
Elaphrus aureus Mull. (2n=31, n=15+X), Elaphrus ullrichii Redt. (2n=3
1, n=15+X); Scarabaeidae: Oxythyrea funesta (Poda) (2n=19, n=9+X); Cer
ambycidae: Agapanthia violacea (F.) (2n=20, n=9+Xy(p)), and Chrysomeli
dae: Oulema gallaeciana (Heyd.) (2n=16, n=7+Xy(p)), Colaphus sophiae (
Schall.) (2n=27, n=13+X), Phaedon cochleariae (F.) (2n=34, n=16+Xy(p))
. The chromosome number and sex determining system of four species are
described for the first time. Evolutionary trends in karyotypes of th
e studied beetle groups are briefly discussed.
