Abstract
Aenigmaphes gen. n. is described for a New Guinean Aenigmaphes papuanus sp. n. The new genus is characterized by several unique features, among others, by the pronotum with one pair of adjacent antebasal pits at middle, both situated in a deep median longitudinal groove, and the posterior margin of each mesocoxal rest demarcated by a step-wise ridge, which extends laterad and is bent posterad to connect with the lateral metaventral margin far behind the mesocoxae. The adult of the new species is minute, wingless and microphthalmous, which may be adaptations to subterranean life. Females of an undescribed species of Aenigmaphes are also recorded from Sulawesi. Relationships of the new genus within Glandulariini remain unclear.
