Further notes on Chinese Cordulegastridae (Insecta: Odonata: Anisoptera)

After the description of new species of Cordulegastridae from China by Zhou (1988) and Zhu & Han (1992), additional specimens have been described by van Pelt (1993) and Lohmann (1993). In this paper additional material of Anotogaster cornutifrons Lohmann, 1993, is reported upon. Neallogaster lieftincki Lohmann, 1993, is synonymized with Cordulegaster jinensis Zhu & Han, 1992. Some further comments are made on Lohmann's paper. A single male from Tsingtau (Ch'ing-tao, Shantung, NE China) is described as Cordulegaster (mentalis spec. nov., being the sole representative of the C. boltonii (Donovan, 1807) species-group in the East Palaearctic.
