Supplementary description. Belongs to the M. terminata species group. Male lectotype. Head reddish­brown to dark brown, pronotum rufous, elytra black.Antenna generally yellowish, three or four terminal antennomeres darkened. Palps and legs yellowish brown, tibiae distinctly paler than femora. Head about 1.3× as long as wide, basal margin rounded in one arc with posterior temporal angles. Compound eye large, slightly protruding from lateral outline of head. Head dorsum moderately glossy, sparsely punctate with sporadic, circular punctures. Intervening spaces much wider than punctures, smooth. Dorsal cranial setae whitish, sparse, appressed.Antenna moderately thickened in apical third. Terminal antennomere elongate, apically pointed, about 3× as long as penultimate antennomere. Pronotum about 1.2× as long as wide, narrower than head across eyes, moderately glossy, rounded at anterior margin. Lateral margins strongly impressed in posterior half. Latero­basal pronotal fovea broad and deep. Pronotal disc slightly convex in dorsal aspect, punctures and setae sporadic, similar to those on head. Elytra about 1.5– 1.6× as long as wide, rounded laterally, dorsally slightly convex. Humerus obsolete. Apex of elytron modified, channel of gland forming oval opening and short, broad process at posterior margin. Elytral disc moderately glossy, comparatively denser, slightly stronger punctate than forebody. Intervening spaces about twice as wide as punctures, smooth, glossy. Elytral setae whitish, moderately long and dense, subdecumbent to appressed. Legs without modifications, tibial terminal spurs paired. Tergite VII subtruncate at posterior margin. Morphological sternite VII subtruncate at posterior margin. Aedeagus as in Fig. 14C–E , tegmen apex with long, rod­like and apically strongly hooked process; endophallic armature with a pair of large, curved spines and some small spinules.

Sexual dimorphism. Female generally more robust than male, elytra comparatively more wide, elytral apex without modifications.

Ecology. Unknown.

Distribution. Greece (Cyclades & Dodecanese islands). Record by Pic (1896b: 180) from Karpathos Island based on misidentified specimen of M. rubronotata (Pic, 1896) stat. nov. (see below). Specimens recorded by Chikatunov et al. (2004) and Uhmann (2005) from Israel were not verified during this study and thus the occurrence of M. corallicollis in the Eastern Mediterranean requires further confirmation.

Chorotype. E­Mediterranean (3.03 EME), here considered restricted to Cyclades & Dodecanese islands.
