Further notes on Raveniola Zonstein, 1987 (Araneae: Nemesiidae) in China, with descriptions of two new species from Sichuan

Two new eastern Asian species of Raveniola Zonstein, 1987, R. reuteri sp. nov. (♂), and R. yalong sp. nov. (♂♀), are diagnosed and described, based on specimens from Sichuan, China. The two new species are clearly distinguishable from all known Chinese congeners in details of colouration, different somatic structures (including shape and arrangement of the spinnerets), the unique conformation of the male palp and, in the case of R. yalong sp. nov., also in spermathecae. The characters that have taxonomic significance for dividing the known Eastern Asian Raveniola spp. into species groups are briefly considered, and the number and species composition of these possible groups are preliminarily discussed.
