Fig. 16 in Taxonomy, larval morphology and cytogenetics of Lihelophorus, the Tibetan endemic subgenus of Helophorus (Coleoptera: Hydrophiloidea)

Fig. 16. Mitotic chromosomes from mid-gut cells of males of Helophorus (Lihelophorus) species from Qinghai: Zuimatan, arranged as karyotypes. a–b – H. lamicola Zaitzev, 1908 (a – plain (Giemsa stained); b – same nucleus, C-banded). c–d – H. ser Zaitzev, 1908 (c – plain; d – same nucleus, C-banded). e–h – H. yangae sp. nov. (e – plain; f – same nucleus, C-banded; g – plain; h – same nucleus, C-banded). The y chromosome is missing from the preparation shown in c and d and in d the y chromosome from a different C-banded preparation with a similar degree of chromosomal condensation has been inserted.
