Remarks. Chydaeus convexus was previously known only from the southern parts of the Gaoligong Shan in western Yunnan Province, China ( Kataev & Schmidt 2006; Kataev et al. 2012). The new material was collected in the southern parts of the Gaoligong Shan and in the north-eastern part of the Laobie Shan, located to the south-east of the Gaoligong Shan ( Fig. 70 ). A single male collected in the Laobie Shan is very similar in the aedeagus structure to the males examined from the Gaoligong Shan, but differs from them in having elytral microsculpture on disc slightly more distinct and pro- and mesotarsi less strongly enlarged; parascutellar setigerous pore is present in each elytron. Additional material from the Laobie Shan is needed to determine the status of this male.
