Andracalles panin. sp. from the Three Kings Islands: evidence for copulation mechanics (Coleoptera: Curculionidae: Cryptorhynchinae)

Andracalles pani n. sp. is described and figured. It is one of 9 species of cryptorhynchine weevil so far known from the Three Kings Islands, and like all but one of the others it has a sister-group on the main islands of New Zealand. The male and female genitalia of A. pani differ markedly from those of its congeners. The male possesses a very unusual large toothed sclerite in the endophallus, and the endophallus itself may be permanently everted. The female vagina is thickened posteriorly in such a fashion as to receive and limit the movement of the male aedeagus, indicating the function of the aedeagus as an intromittent organ.
