Description. Coloration ( Fig. 37-38 ). Head iron grey to dark slate blue, mouthparts sienna to sooty, antennae sooty, bases of antennomeres 2 and 3 mostly paler, sienna. Prothorax, meso- and metasternum and abdomen iron grey to dark slate blue, last abdominal segment sometimes sienna. Femora iron grey to dark slate blue, anterior tibiae rusty, sometimes with darker tips, middle tibiae iron grey or rusty with darkened outer side, hind tibiae entirely iron grey or more or less infuscate on its middle and/or outer side. All tarsi sepia to sooty. Scutellum and elytra iron grey to dark slate blue. Both sexes exist with alternative coloration dark greenish olivaceous body and yellow pubescence instead of white one.

Male. Eyes moderately protruding, head across eyes slightly narrower than pronotum, head before eyes ca 1.5 times as long as eyes in dorsal view, head behind eyes moderately arcuate, narrowed posteriorly. Eyes moderately reniform. Antenna reaching elytral midlength, last antennomere slightly constricted in ca two thirds of its length. Surface of head rather deeply imbricate-punctate, covered by long, recumbent white or yellow pubescence, matt. Pronotum distinctly longer than wide, narrowly cordiform, anterior margin widely rounded, anterior corners rounded, lateral margins sinuate, posterior corners rounded, posterior margin widely rounded or very shallowly emarginate in middle. Surface of pronotum densely and rather deeply imbricate-punctate, covered by long, recumbent white or yellow pubescence, matt. Two anterior depressions shallow but distinct, prebasal depression shallow but very wide. Elytra distinctly narrowing posteriorly, each elytron apically rounded, elytral nervation slight to well developed, more distinct in basal half of elytron. Surface of elytra rugulose-lacunose, covered by long, recumbent white or yellow pubescence, matt, sometimes semilustrous basally. Last abdominal segment, projections of urite VIII, tegmen and aedeagus as in Figs. 15-20.

Female. Antenna shorter than in male, not reaching elytral midlength. Pronotum as long as wide to moderately longer than wide, pronotal depressions shallower than in male, less distinct. Elytra narrowing posteriorly only in their posterior half. Last abdominal segment as in Fig. 21.

Length J ♀: 6.2-10.0 mm.

Differential diagnosis. Chitona macedonica sp. nov. is closely related to C. cretica Fairmaire, 1863 , and C. incana (W. Schmidt, 1846) , from which it differs especially by the preapical part of paramere being not emarginate dorsally in lateral view and by the projections of urite VIII only slightly dilated preapically in lateral view.

Distribution. Greece: Central Macedonia, Thessaly, Naxos Island; Macedonia; southern Bulgaria.
