Remarks. The species was described based on 17 females from Mongolia, Ulaan Baatar and these are the first additional specimens since the original description. This is also the first record of the species in China (Fig. 53 ). Rhinodontus mongolicus is very easy distinguishable from all other species of Rhinodontus by the prominent sulci covering eyes in dorsal view and by the slender antennal scape.
