Micrillus variceps group

This new species group currently includes only Micrillus variceps (see description below). It is characterized by undilated protarsomeres I-IV, moderately large body size, moderately dense punctation of the head, a relatively slender pronotum with dense micropunctation and a discal row composed of 6-8 macropunctures on either side of midline, very dense punctation of the abdomen, a rather large and deep posterior excision of the male sternite VIII, and a nearly symmetric aedeagus with a weakly sclerotized ventral process and with a large and long dark membranous structure, but without sclerotized spines in the internal sac.
