Clypeolus veratrus (Broun) Kuschel, 1982: 276 View in CoL .

Diagnosis: Substantially larger than C. pascoei . Elytra with the humeral angles forming strong carinae; interstria 3 also strongly carinate and the elytra from here inflexed mediad. In extreme instances, interstriae 9 and 10 are almost on the same plane as the abdominal ventrites. Males are readily distinguished by the long crests of erect setae running along interstria 4. Females lack these crests and can be easily confused with C. pascoei ; however, they can be distinguished by their larger size, and by having darker scales on the rostrum and vertex.

Distribution: North Island: ND (Poor Knights Is, Hen and Chickens Is (Lady Alice I.)), AK (Noises Is, Watchman I.), CL (Great Barrier I., Mercury Is (Great I. & Middle I.), Aldermen Is (Ruamahuaiti)).

Remarks: This species is restricted to offshore islands. This species appears to be sexually dimorphic, with the females lacking the distinctive elytral crests of the males. This species is evidently closely related to C. pascoei .
