Abstract: The taxonomic characteristics and position as well as delimitation of the genus Arachnocrea are dis-cussed. One species Arachnocrea scabrida Doi collected from Xishuangbana Dai Autonomous Prefecture, Yun-nan Province, P.R.China is compared with the specimens from Japan (holotype) and New Zealand as well as other specimens on macro - & micro - morphology and anatomy. The range of variations of this species was de-fined. It is a new record to China. In spite of the geographical distribution of all species in the genus Arach-nocrea in the world shows the modem patterns of the temperate zone in the north hemisphere. It can be stretched to the tropical area of Southeast - Asia, it is possible that the genus was originated in this area histor-ically. It is suggested that the tropical area might be a center of differentiation of species in the genus.

Key words: Arachnocrea, A.scabrida, New record genus to China
