Etymology: The specific epithet is the past participle of the Latin verb corrumpere (to decay) and alludes to the fungus-shaped internal structures of the aedeagus.

Description: Body length 1.0– 1.2 mm; length of pronotum 0.30–0.35 mm; width of pronotum 0.40–0.44 mm; length of antennae 0.45–0.50 mm. Habitus as in Fig. 14 . Colouration: body yellowish-red.

Eyes composed of approximately five ommatidia.Antenna with antennomeres VIII–X moderately transverse.

Pronotum 1.20–1.25 times as broad as long, broadest in anterior half, and moderately convex in cross-section; lateral margins straight in posterior half; punctation as fine as that of elytra.

Elytra noticeably broader than pronotum, anteriorly with small transversely oval impression with tomentose whitish pubescence; humeral carina pronounced, approximately as long as the combined length of the basal four antennomeres, inner margin of this carina sharply delimited.

: protibia unmodified; metaventrite depressed or shallowly impressed; aedeagus ( Fig. 57 ) short, broad, and apically truncate, approximately 0.25 mm long; internal sac with structures of distinctive shapes; paramere apically extending nearly to apex of median lobe, with short apical seta.

Comparative notes: Among other species of this group, C. corruptum is reliably identified only based on the shape and the internal structures of the aedeagus.

Distribution and natural history: The distribution includes several localities in Mersin and Adana provinces, central South Anatolia ( Map 3 ). The specimens were sifted in various forested ( Pinus , Juglans , Quercus ilex , Cedrus , Juniperus , etc.) and unforested habitats (grassy slopes) or found under stones at altitudes of 430–1450 m.
