C o m m e n t: The original description is based on an unspecified number of syntypes; a locality is not specified ( SHARP 1888). Only one syntype, a male, was located in the Sharp collection at the BMNH; it is designated as the lectotype. In external and sexual characters, A. armatus is highly similar to the West Palaearctic A. tricuspis EPPELSHEIM 1884 ; the aedeagus is practically identical. The only difference between the two species is the shape of the median tooth of the male tergite VIII, which is broader and stouter in A. tricuspis . More material is needed to clarify if this difference is an expression of inter- or intraspecific variation. The sexual characters of A. armatus are illustrated in Figs 48- 50 .

The species was previously known only from Japan and Taiwan. The above specimens represent the first record from mainland China.
