Abstract: | The family Tetrablemmidae is reported for the first time from China, with five new species and one new genus. Lehtinenia gen. n., which is erected to accommodate Lehtinenia bicornis sp. n., is characterized by the modified embolus, special modifications on chelicerae, and a Tetrablemma-type vulva. The other four new species are: Ablemma prominens sp. n., Brignoliella caligiformis sp. n., Brignoliella maoganensis sp. n., and Tetrablemma brevidens sp. n., all collected from caves. A phylogenetic analysis of the subfamily Tetrablemminae based on 41 morphological characters shows that the tribe Brignoliellini is the most basal group in the subfamily, rather than the sister group to the tribe Fallablemmini. Lehtinenia gen. n. and the genera Ablemma, Sulaimania, and Maijana together form a monophyletic group. |
