Vitronura acuta Deharveng & Weiner, 1984

Diagnosis. V.acuta is characterized by mandible 4 teethed, maxilla hook-like, claw toothless, labium ogival, without x papilla. Its body tubercles and chaetotaxy are similar to V. zhejiangensis sp. nov. V. acuta is also similar to V. qingchengensis in body chaetotaxy and antennal structure. However, V. acuta is different from the latter by not having inner tooth on claw and having four-dentated mandible, while V. qingchengensis has an inner tooth on claw and five-dentated mandible. The differences among V. zhejiangensis sp. nov., V. acuta and V. giselae see the remarks of V.tianmua sp. nov.
