Review of New Zealand Cryptamorpha (Coleoptera: Silvanidae), with a description of a new species from the Three Kings Islands

Abstract

A new species of silvanid beetle, Cryptamorpha triregia sp. n. is described from the Three Kings Islands, New Zealand. A key to the New Zealand Cryptamorpha species and diagnoses to the previously described Cryptamorpha brevicornis (White) and Cryptamorpha desjardinsi (Guérin-Méneville) are provided. Examination of the type series of Cryptamorpha curvipes Broun and Dendrophagus suturalis White show that C. curvipes is a synonym of C. brevicornis and confirms that D. suturalis is a junior synonym of C. desjardinsi, despite formerly being considered to be a synonym of C. brevicornis. Lectotypes are designated for C. brevicornis and D. suturalis.
