TYPE LOCALITY. Mt Percival, near Hanmer, northern Canterbury. 
Material examined. Holotype oc’, allotype 9, paratype @. 
Distribution. Known only from the type locality. 
The species is named in honour of Mr P.M. Johns, who has greatly increased our 
knowledge of the Canterbury species of Mimopeus by his assiduous collecting. 
Mimopeus convexus sp.n. (Figs.96,103) 
Most closely related to M. rugosus. Superficially similar to M. tibialis, but readily 
distinguished by the structure of the aedeagus; and the rounded, non-dentate lateral 
projection of the emargination of postgenae at base of cardo. 
MALE 
Elongate oval, convex (Fig.96). Dorsal surface and legs reddish black, slightly shining, 
antennae reddish, ventral surface shining black. 
Dorsal surface. Labrum barely emarginate anteriorly, finely punctate, bearing numerous 
fairly stout setae. Punctures of dorsal surface of head smaller and shallower than in M. 
rugosus interstices flat, surface shining, microsculpture weak; micropunctures small and 
shallow, just visible at 25 x magnification. Pronotum more convex and more transverse than 
in M. rugosus, sides more strongly curved. Punctures smaller and shallower than in M. 
rugosus, macropunctures of disc separated mostly by more than their own diameter; 
micropunctures small and shallow, interstices flat. Surface shining, microsculpture not 
visible at 25 x magnification. Scutellum bearing small, deep punctures. 
Elytra convex, more elongate than in M. rugosus. Costae obsolete, indicated only by 
slight elevations. Basal elytral carina distinct, but only slightly raised shoulder narrowly 
rounded; submarginal channel obsolete. Punctures much smaller and shallower than those of 
M. rugosus interstices only slightly uneven, microsculpture not strong, scarcely visible at 25 x 
magnification.
