( FIG. 6I–K View Figure 6 )
Material examined: Sternolophus solieri Castelnau, 1840: 1 male (BMNH): Egypt, surroundings of Cairo, 10 th Ramadan, R. Angus lgt.
Karyotype: 2 n = 16 + Xy (♂). Chromosomes 1–7 metacentric, 8 subacrocentric, with an even decrease in length along the karyotype. X chromosome is metacentric, as large as chromosome 1.
Note: Agarwal (1960a) provides a meioformula n = 8 + Xy p (♂) for Sternolophus rufipes (Fabricius, 1792) , which agrees with the data presented here.

D–H, Hydrochara: (D–F) Hydrochara caraboides, mitotic karyotype, embryo; (G–H) Hydrochara flavipes, mitotic karyotype, midgut. I–J, Sternolophus solieri (I, male mitotic karyotype; J, meiotic first metaphase from testes). A, C, D, G, I, without treatment. B, E, F, H, C-banded. Habitus figures: (K) Sternolophus solieri; (L) Hydrochara caraboides; (M) Hydrophilus piceus, from Short & Fikáček (2013).
