description: Key to species of genus Antonina based on the morphology of first-instar nymphs
[Williams (2004) described 3 types of first-instar nymph for A. milleri, but our preliminary study based on specimens of A. milleri collected from Beijing, China, shows that type A was not present, type B is the female nymph and type C is possibly the male nymph. Considering that some Antonina species have parthenogenetic reproduction, we have here used type B as the representative for A. milleri.]
