Cladolasma ailaoshan, a new species of the genus Cladolasma Suzuki, 1963 from China (Opiliones, Nemastomatidae, Ortholasmatinae)

The fourth species of the Asian genus Cladolasma, C. ailaoshansp. n. is described from specimens collected in Yunnan Province, China. The new species is distinct from C. parvulum Suzuki, 1963 and C. angka (Schwendinger & Gruber, 1992) in lacking enlarged, dorsally-directed tubercles on the abdominal scutum; and from C. damingshan Zhang & Zhang, 2013 in having keels around the eyes and in the position of the eyes. Differences in male genital structures between the Chinese species are small, while there are more differences with the Japanese species.
