GEOGRAPHICAL VARIATION 
The description is based on the long type series from Jordan, Awatere Valley. There is 
slight geographical variation in development of dorsal and ventral granules, which are rather 
smaller in specimens from Seddon to the north, and rather larger (ventrally only) in 
specimens from Upcot to the south. The apicale of Upcot individuals is more elongate.

Distribution and ecology. Apparently confined to the lower and middle Awatere 
Valley, a dry valley just west of the inland Kaikoura Range, Marlborough. The 
types were collected under stones amongst sclerophyll scrub (Discaria etc.) on the 
banks of a small river near the old Jordan homestead. The remaining material 
collected by me was found under stones in little modified tussock grassland and 
sclerophyll scrub. None was found in sown pasture land. 
Mimopeus clarkei sp.n. (Fig.53) 
MALE 
Smaller than typical M. costellus. Elytral costae less distinct. Sides of pronotum more 
strongly curved, pronotum more convex, punctures smaller, microsculpture of interstices 
weak, surface moderately shining. Elytral granules smaller, confined to lateral and hind 
slopes, costae only slightly raised. Shoulder less prominent, but narrowly rounded. 
Mesosternal intercoxal process relatively broader, median part less convex, Punctation 
of prosternal intercoxal process less dense. Granules of epipleura of elytra small, barely 
visible at 25 x magnification. 
Aedeagus smaller, base of basale more strongly curved downwards; otherwise identical 
with that of M. costellus.
