Pic (1896b: 180) described ‘ Anthicus rubriceps V. Rubronotatus ’ from an unstated number of specimens of which one female was allocated and studied (see above). Winkler (1927: 849) for unstated reason listed the variety as an aberration (‘ Anthicus rubriceps a. rubronotatus ’). This variety is a good, valid species (new status) and therefore not becomes subspecies following article 45.6.4 of the ICZN (1999).

Anthicus humerifer was described from an unstated number of specimens from the same locality and material as Anthicus rubriceps var. rubronotatus ( Pic 1902a: 41) . Both taxa found to be conspecific, and the new synonymy is proposed here.

Supplementary description. Belongs to the M. terminata species group. Male syntype. Total body length 2.5 mm. Forebody rufous, head darker. Elytra black­brown with poorly defined, small, paired pale spot in postbasal area. Antennomeres generally yellowish, three apical antennomeres darkened. Palps and legs yellowish brown, tibiae distinctly paler than femora. Head barely longer than wide, basal margin rounded in one broad arc with posterior temporal angles. Compound eye moderate, slightly protruding from lateral outline of head. Head dorsum glossy, rather sparsely punctate. Intervening spaces smooth, generally about 2–3× as wide as punctures, rarely as wide as puncture diameters. Dorsal cranial setae yellowish, sparse, subdecumbent. Antenna slightly thickened in apical half. Terminal antennomere elongate, apically pointed, about 2.3–2.4× as long as penultimate antennomere, about as long as combined length of 2.5 preceding antennomeres. Pronotum barely longer than wide, narrower than head across eyes, moderately glossy, rounded at anterior margin. Lateral margins moderately impressed in posterior half. Latero­basal pronotal fovea broad and deep, with curved, whitish setation. Pronotal disc slightly convex in dorsal aspect. Pronotal punctures and setae similar as those on head. Elytra about 1.5× as long as wide, laterally slightly widened in apical third, dorsally flattened or barely convex. Humerus broadly rounded, not protruding. Apex of elytron modified, channel of gland forming small, oval opening and short, obtuse angulate denticle. Elytral disc glossy, punctures rather small, generally slightly coarser than those on forebody. Intervening spaces 2–4× as wide as punctures, smooth, glossy. Elytral setae whitish, long, moderately dense, subdecumbent.Legs without modifications, tibial terminal spurs paired. Tergite VII subtruncate at posterior margin. Morphological sternite VII very broadly rounded at posterior margin.Aedeagus as in Fig. 22B–D . Tegmen apex strongly hooked with a small basal denticle on external margin of a hook; endophallic armature with a pair moderate, curved, C­shaped spines (one of spines in a pair is longer than other) and a bunch of smaller, narrow, subparallel spines.

Sexual dimorphism. Female with more robust body, comparatively wider, apically simple elytra.

Interspecific variability. Elytra without pale spot in most specimens except holotype M. rubronotata .

Ecology. Unknown.

Distribution. Greece (Sporades Islands, Dodecanese Islands: Rhodes), European Turkey.

Chorotype. E­Mediterranean (3.03 EME), considered restricted to Sporades, Rhodes and coastal areas of W Turkey.
