Diagnosis

Currently known only by male specimens. Recognized by its shiny castaneous body; pronotum with narrow, distinct, yellow stipe along posterior margin ( Figs 1 View Figs 1–2 , 16 View Figs 14–17 , 26–27 View Figs 24–27 ); male genitalia as described below ( Figs 3–5 View Figs 3–5 ). These characters enables this species to be readily distinguished from the other congener, M. pentatomus (see below).

Etymology

From Latin, ‘ castaneus ’ (‘castaneous brown’), referring to the basic body coloration of this new species.
