Koyaga Ueda Type species: falca Butler (China, Korea, Japan). This genus has facies typical of the Deltote group, and is best defined on features of the male and female genitalia, though the cilia of the male antennae are longer than in other members of the group. The valves of the male are elongate, usually narrowed over an extensive central section, but with dorsally directed processes from the costa or just interior to it in the distal part of the narrowed section or, in the type species, in the broader apical section. The aedeagus vesica usually has a cluster of small but often elongate spines on a patch of sclerotisation. In the female, the ductus bursae is longer than the corpus bursae, inserted at about one third from the base of the corpus, which extends posteriorly to give rise to the ductus seminalis. The genus currently consists of five east Asian species as discussed by Ueda (1987) and, tentatively, the Bornean species described below. |
