Diagnosis

Chimarra fotobohitra sp. nov. differs from the other species of the group by the ventral branch of tergum X, which is short and forms with the dorsal branch an angle of about 20° ( Fig. 6A View Fig ). When it is measurable, this angle is greater than 40°, except in C. gattolliati sp. nov. and C. lehibemavo sp. nov., where it is around 35° ( Fig. 7A View Fig , 2A View Fig ). Another remarkable character of this species is the strong median narrowing of the dorsal lamina ( Fig. 6D View Fig ), also observed in C. gensonae sp. nov., but with a different shape ( Fig. 8E View Fig ).

Etymology

The name is that of the river where the holotype was collected.
