A new genus and three new species of Hemiptera: Heteroptera: Enicocephalomorpha: Enicocephalidae: Enicocephalinae are described from Malaysia: Sabah, viz. Phaenicocleus n. gen. sabahensis n. sp. (type species), P. schwendingeri n. sp. and P. minor n.sp. (all species male-based). The new genus is macropterous and belongs to that group of Enicocephalinae characterized by presence of large, closed discai cell and absence of basal cell in forewing. The species are distinct in the character states of themedian of pronotum, shape of unpaired sclerite of the pro-eusternum, and shape and length of a median keel of meta-eusternum - these are characters previously unemployed as diagnostic in the Enicocephalidae.
