Abstract
A new species of mudfish, Neochanna, is described from Northland. Neochanna heleios n.sp. is known from only three ephemeral wetland sites on the Keri keri volcanic plateau and is abundant only at the type locality. The new sp ecies has a head resembling that of the brown mudfish, Neochanna apoda, and a caudal region resembling that of the black mudfish, Neochanna diversus. It can be distinguished from all Neochanna species in having a reduced numb er of principal caudal fin rays (13 or less). Morphometric and meristic com parisons with N. apoda and N. diversus are provided.
