Abstract
A new species of Enicocephalidae: Enicocephalinae, Phaenicocleus granulosus sp. n. (based on a female), is described from Sabah and compared with the other three species of the genus (based on males). Autapomorphies of the genus (particularly reduced armature of fore tibia and tarsus, interrupted posterior claval vein AA3+4, striking occurrence of large setigerous tubercles - the latter shared with Australian Usingeriella) are stressed and partly discussed. A new key to genera of Enicocephalidae with forewing basal cell absent and closed discal cell present is provided.
