— Outer lobe of male paramere without teeth in the middle of hind margin (might have a tooth at the top). Inner lobe of the paramere not modified into a sharp black spine. Female terminalia longer; proctiger straighter; subgenital plate, in profile, pointed apically................................ 3

2(1). Inner lobe of male paramere consisting of a black spine that shows easily in lateral view. Females cannot be separated...................................................... H. mimosae Crawford
