Diagnostic description.
This species is extremely similar to the preceding, differing mainly in the following characters: length: 2.03-2.37 mm, width: 1.72-2.00 mm; body slightly narrower, less broadly rounded; pronotum with more numerous, ~40, lateral discal punctures; elytron with subhumeral striae absent, striae 1-2 complete, 3rd stria complete or rarely narrowly interrupted at middle, 4th stria present in basal fourth and as short apical fragment, 5th stria represented by short apical fragment, sutural stria present in apical two-thirds, more frequently connected to apical marginal elytral stria (about half of available specimens); 1st abdominal ventrite with a small fovea behind the inner corner of metacoxa, lateral stria present, ending in fovea, not continuing laterad behind metacoxa; propygidium and pygidium with similar dense ground punctation, the coarse punctures of propygidium much more dense and numerous, coarse punctures of pygidium also more numerous; apical marginal stria absent. Male genitalia indistinguishable from those of Operclipygus foveiventris (see Figs 75 A–C, G).
Remarks.
Operclipygus marginipennis is very similar to the preceding species but differs by its small postmetacoxal fovea, usually complete 3rd dorsal elytral stria, and more numerous lateral pronotal punctures (Fig. 73G). We restrict the type series to those specimens from Belize, due to evident variation in completeness of the 3rd elytral stria, pronotal punctation, and ventral striae among localities.
Etymology.
This species’ name refers to the apical stria along the posterior elytral margin.
