Diagnosis

Body length: 4.40 mm, robust. Black, laterals of pronotum, hypomere and humeral region reddish; very shining. Seven rows of coarse elytral punctures. Lacking microsculpture. Medium lobe strongly curved in lateral view; parameres thin.

Etymology

The species epithet is a Latin word meaning ‘runaway’, because the holotype almost escaped when I tried to collect it.

Description

COLOURATION. Black. Humeral region, laterals of pronotum and hypomeron reddish ( Figs 3A–C, F View Fig , 4A– B View Fig ). Legs dark red-purplish ( Fig. 4C–E View Fig ). Antennomeres I–VI and XI, mouthparts, and tarsi ochreous ( Figs 3F View Fig , 4F–H View Fig ).

Submesocoxal lines parallel to coxae, with few coarse punctures ( Fig. 4B View Fig ).

WINGS. Elytra rectangular, longer than wide; sutural and basal striae connected; basal stria punctate, reaching almost middle of elytra ( Fig. 3A View Fig ). Seven rows of coarse punctures ( Fig. 3A View Fig ). Epipleuron coarsely punctate ( Fig. 4B View Fig ). Apical spines small ( Fig. 4K View Fig ).

LEGS. Femora sparsely and coarsely punctate ( Fig. 4C–E View Fig ). Meso- and metatibiae curved ( Fig. 4D–E View Fig ), with two large apical spines ( Fig. 4I–J View Fig ).

ABDOMEN. Abdominal ventrite I coarsely punctate, denser laterally; submetacoxal bead with close and coarse punctures ( Figs 3B–C View Fig , 4B View Fig ). Propygidium and pygidium micropunctured and with coarse punctures; disc with strigulate microsculpture anteriorly ( Fig. 4L View Fig ).

Male

Sternite VIII rectangular with a rounded projection ( Fig. 5A View Fig ). Tergite VIII wide and rounded ( Fig. 5B View Fig ). Tergite IX with rectangular-shaped ventral struts ( Fig. 5C View Fig ). Tergite X ( Fig. 5D View Fig ) as long as wide. Sternite IX thicker posteriorly ( Fig. 5E View Fig ).

AEDEAGUS. Strongly sclerotized. Basal bulb large; apical lobe curved in lateral view ( Fig. 5F–H View Fig ); dorsal openings forming an upside-down triangle ( Fig. 5H View Fig ).

Host

Collected from an undetermined mushroom on the border of a field trail ( Fig. 93A–B View Fig ).

Remarks

The humeral reddish area is similar to C. pici von Groll & Lopes-Andrade, 2021 and C. loebli von Groll & Lopes-Andrade, 2021 but differs by the larger size and by the pronotal lateral reddish marks. The pronotum colouration resembles C. anale Reitter, 1880 but the elytral colouration is different. The aedeagus is similar to that of C. pici but it is less robust and the sclerites are in a different shape. The aedeagus is also similar to that of C. lescheni von Groll & Lopes-Andrade, 2021 but it is larger and more robust.
