Mimopeus johnsi sp.n. (Fig.95) 
A distinctive species, most closely related to M. costellus. In some respects it resembles M. 
tibialis, but may be distinguished readily by the outer apical angle of the anterior tibia and 
the outer angle of the postgenal emargination, neither of which are dentate; by the broader 
and more clearly defined pronotal and elytral submarginal channels; and by other less 
obvious features. 
MALE 
Elongate oval, convex, black. 
Dorsal surface. Dorsal punctures smaller than in M. costellus. Pronotum more convex, and 
sides more strongly curved than in M. costellus; submarginal channels present. Punctures of 
disc separated mostly by about 2 x their own diameter, interstices flat, microsculpture 
strong, clearly visible at 25 x magnification. Micropunctures distinct, deep to shallow, clearly 
visible at 25 x magnification. Elytra convex, elongate, sides subparallel basally. Flat 
submarginal channels extending from shoulder two thirds distance to apex, inner angle 
distinct; epipleural carina slightly reflexed. Shoulder narrowly rounded, but not prominent. 
Basal carina sharp, distinct, but barely or not raised. Elytral costae indistinct; granules 
absent except for a few small ones, which are scarcely visible at 25 x magnification, on 
submarginal channels. Punctation and microsculpture similar to that of pronotum. Setae of 
macropunctures clearly visible at 25 x magnification, especially on lateral slopes. 
Ventral surface. Outer angle of maxillary emargination of postgenae slightly elevated, but 
bluntly rounded, not at all dentate. Granules of sterna and epipleura smaller than those of 
M. costellus, but granules of postgenae and proepisternaum larger. Intercoxal processes 
broader than in M. costellus. Punctures of ventral surface small to minute. 
Legs. Femora finely punctured, smooth. Front tibiae very uneven below, and bearing small 
stout bristles. Middle and hind tibiae uneven and bearing similar bristles on lateral and 
ventral surfaces; other surfaces bearing finer and longer setae and less uneven, but deeply 
punctate. 
Aedeagus (Fig.95). Rather similar to that of M. costellus, but apicale more elongate. 
Dorso-lateral surface of apicale forming a distinct longitudinal carina, below which is a 
longitudinal lateral groove extending from base towards apex, distinctly impressed for the 
first one third of the distance. Ventro-lateral angle distinctly carinate from base one quarter 
of distance to apex. These characters of the aedeagus appear to be unique in the genus. 
FEMALE 
Not evidently distinguishable from male except by genitalia and terminal abdominal 
sclerites.
