A new species of mudfish,
Neochanna, is described from Northland.
Neochanna heleios n.sp. is known from only three ephemeral wetland sites
on the Kerikeri volcanic plateau and is abundant only at the type locality. The
new species 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 number of principal caudal fin rays (13 or less).
Morphometric and meristic comparisons with
N. apoda and
N.
diversus are provided.
