C o m m e n t: Porocallus wrasei was originally described based on a male and a female from a locality in the Gaoligong Shan, western Yunnan, and subsequently recorded from additional localities in Yunnan southeastwards to the Dawei Shan near Pingbian, close to the border with Vietnam ( ASSING 2012, 2015a). The remarkable intraspecific variation of P. wrasei was already addressed in ASSING (2015a). The above specimens are distinguished from all other specimens seen thus far by darker coloration (body practically completely black, except for the narrowly yellowish posterior margin of the elytra and the dark-reddish antennomere XI). The median lobe of the aedeagus ( Fig. 8 ) and the spermatheca ( Fig. 9 ), however, are within the range of intraspecific variation.
