Host fungi

Adults were collected from Psathyrella candolleana (Fr.) Maire ( Agaricales , Psathyrellaceae ) (1 record, 1 individual), Psathyrella sp. (1, 11), Agaricus sp. (1, 18; von Groll et al. 2021: figs 1–4), A. dulcidulus Schulzer (1, 4), A. sylvaticus Schaeff. (1, 20) and Entoloma (Inocephalus) sp. ( Agaricales , Entolomataceae ) (1, 2).

Remarks

Measurements similar to those of C. newtoni , except for the comparatively longer antennae. It was found co-occurring with C. newtoni in the same host fungi. However, they differ at first view by the coloration: C. lescheni sp. nov. is brown with few individuals of the same coloration as C. newtoni (pronotum reddish brown and elytra black); a few individuals of C. newtoni are brown, but darker than C. lescheni . They also differ by the microsculpture of the metaventrite: present in C. lescheni and absent in C. newtoni . Tergite VIII in males is triangular in C. lescheni and straight apically in C. newtoni . Parameres in C. newtoni are longer and the sclerite of the internal sac is also different. Tergite VIII in females has an invagination in C. lescheni , while in C. newtoni it is entire.
