Micrillus suturalis group

The M. suturalis group is characterized by a relatively large, slender, and weakly asymmetric aedeagus with a long series of conspicuous sclerotized spines in the internal sac, and by a broad and shallow posterior excision of the male sternite VIII (ASSING 2013). This group includes two species, M. suturalis, a species distributed in the south of the Oriental region and M. kongi, a new species from Cambodia described below. In external characters they are similar to species of the M. badius group, but distinguished by smaller body size and undilated protarsomeres I-IV.
