A chromosomal analysis of three species of Timarcha (Coleoptera, Chrysomelidae, Chrysomelinae)

Abstract. The karyotypes of three species of Timarcha Latreille, 1829 have been analysed. Timarcha (Metallotimarcha) metallica (Laicharting, 1781), has 18 + Xy(p) male meioformula and 2n = 38 chromosomes, similar to those found in the two species of subgenus Americanotimarcha Jolivet, 1948, in agree...

description Abstract. The karyotypes of three species of Timarcha Latreille, 1829 have been analysed. Timarcha (Metallotimarcha) metallica (Laicharting, 1781), has 18 + Xy(p) male meioformula and 2n = 38 chromosomes, similar to those found in the two species of subgenus Americanotimarcha Jolivet, 1948, in agreement with morphological and molecular phylogenetic grounds. Timarcha (Timarcha) carmelenae Petitpierre, 2013 displays 9 + Xy(p) and 2n = 20 chromosomes as in morphologically related Andalusian species, whereas Timarcha (Timarcha) parvicollis ssp. seidlitzi Kraatz, 1879 shows 11 + Xyp and 2n = 24 chromosomes, clearly differing from the previous species. These results are discussed in order to get an insight into the main trends of the chromosomal evolution in Timarcha.
