Seven of the species described below belong to the Cis pacificus group: Cis bicolorellus sp. nov., C. christmasensis sp. nov., C. densus sp. nov., C. howensis sp. nov., C. latemarginatus sp. nov., C. macilentus sp. nov., C. pycnostictus sp. nov..These have an oblong to somewhat elongate body, very fine dorsal vestiture, dual elytral punctation, carinate prosternum, and usually a vertexal sex patch in the male and simple anterior pronotal edge in both sexes. This group includes a number of species distributed throughout Southeast Asia, and the East Indies to New Guinea, Australia, New Caledonia and the Pacific and west at least to the Seychelles. In addition, there is a single species, Cis apodemus , sp. nov., in the Cis compressicornis group, which also includes Cis compressicornis Fairmaire ( Fiji) , Cis solomonensis Blair (New Guinea) and several undescribed species from Malaysia, the Philippines, Indonesia, New Guinea and the Pacific. The Cis multidentatus group is represented by C. rhaibocerus sp. nov. and the Cis literatus group by C. brachytrichus sp. nov. The remaining four new species, C. depressus sp. nov., C. incomptus sp. nov., C. occidentalis sp. nov and C. prominens sp. nov., are not clearly aligned to previously recognised species groups.
