Figure 22 - C-banded mitotic metaphase of male complement of Gonatoxia maculata (A), female Gonatoxia immaculata (B), male Gonatoxia furcata sp. n. (C) as well as both male (D, F, G) and female (E) of Gonatoxia helleri sp. n. Arrows indicate biarmed chromosomes in Gonatoxia furcata sp. n. (C). In Gonatoxia helleri sp. n. the long polymorphic pair 2 shows three main karyomorphs in which homologous chromosomes differ in their morphology: both meta- or submetacentric (D, E), meta/submetacentric : acrocentric (F) and both acrocentric (G). X, sex chromosome. Scale bar = 10 µm.

Figure 15 - Left wings of male Gonatoxia maculata (A), Gonatoxia helleri sp. n. (B), Gonatoxia immaculata (C) and female Gonatoxia furcata sp. n. (D).

Also Gonatoxia helleri sp. n. has a white borderd costal margin with veins branching off white and thickened (left arrow).
