Dear Louis
I do not exactly mean what you need to know but,
In Corixidae (aquatic Heteroptera) the male has an assymetrical last abdominal segment and the genital capsule within is directed to either left or right position dependent on the genus. In the female the abdomen is symmetrical.
Occasionaly however, in some individuals of a male species (for instance Sigara striata) a mirror-image occurs i.e species with a normal position of the genital capsule directed to the right (or left) had the capsule reversed to the left (or right). I have seen this on some occasions in Sigara striata and rarely in Corixa punctata. Also in the larva of some Trichoptera or (aquatic) Coleoptera species there is asymmetry in the mouthparts. But I think that asymmetry occurs in many species.
If you mean if two sibling species has some part reversed, than I know of no species, but aberrant species of a normal species do occur (see above).
