Differential diagnosis. Gonioctena ( B.) mauroi is very similar to G. ( B.) longshengensis sp. nov. and G. ( B.) medvedevi in body shape, coloration and setose aedeagus. From these two species, G. ( B.) mauroi can be distinguished only by aedeagus subparallel-sided with apical process widest in middle and slightly narrower than median lobe (subparallel-sided with apical process broad, widest in apical 1/3 and subequal to median lobe in width in G. ( B.) longshengensis sp. nov. and moderately narrowed with apical process moderately widened to lateral tooth-like projections near apex in G. ( B.) medvedevi ). Gonioctena ( B.) kuatunensis sp. nov. differs in semicircular apex of aedeagus (triangular or subtriangular in other species). Distribution. Vietnam: Lang Son Province ( Fig. 13 View Fig ).
