Hawaiian endemic Copiphorini: Systematics and acoustics (Orthoptera: Tettigoniidae: Conocephalinae)

The endemic Hawaiian Copiphorini fauna consists of two lineages: Conocephaloides and Banza. The genus Conocephaloides is resurrected, but the type species appears to be extinct. A species found on Nihoa Island described as a Banza is transferred to Conocephaloides. Banza is represented on all of the main islands at mid to upper elevations in wet forests. The first acoustic analysis of the extant Hawaiian Copiphorini provides a guide to compare morphological and coloration characters. With new characters for Banza the status of Kauai Island species is changed, a sibling species not previously recognized is described from Maui Island and the variation of the Hawaii Island Banza species now appears to form a cline. The song of the Nihoa Island Conocephaloides species is unusual for Copiphorini katydids.
