Ischnosoma spec. 2

" CHINA: N-Yunnan, Dali Bai Nat. Aut. Pref., Diancang Shan, 4 km W Dali old town, 25°41.4' N, 100°06.7' E, 2900–3000m, E slope with devastated forest and old pine forest, litter and mushrooms sifted, 31.VIII.2003, leg. M. Schülke [ CH 03-20]", 1♀ (cSch).

This brachypterous species is characterized by small eyes, the ocular seta inserting in the median portion at some distance behind the eyes, the inner anterior seta of the pronotum inserting at some distance from the anterior margin of the pronotum, elytra with very distinct microsculpture, the absence of a carina at the anterior margin of the pronotum. These character combination suggests that this species is most likely not a member of the I. pictum group, but probably represents an undescribed species group.
