A new species of Lepidotrigla from the Kermadec Islands in New Zealand waters is described. This species differs from Lepidotrigla brachyoptera Hutton, the other New Zealand Lepidotrigla, in having smaller scales (20 rows below the lateral line versus 10–11),
more second dorsal and anal fin rays (D2 Dorsal 16–18, mean 16.9 versus 15–17, mean 15.7 and Anal 16–18, mean 17.3 versus 16–18, mean 16.4), narrower interorbital width (5.3–6.0%SL. mean 5.6%SL versus 6.0–9.8%SL, mean 8.3%SL), and shorter gill
rakers (1.3–1.7%SL, mean 1.5%SL versus 2.0–2.7%SL, mean 2.3%SL). The two species are allopatric but appear to be more closely related to each other than to other congeners. L. brachyoptera is redeseribed and compared with the new species.
