Description
DIAGNOSIS A member of the punctatissima group uniquely characterized by the elongate head of the minor; and by the bidentate hypostoma and dense, short, uniform, and subappressed gastral pilosity of the major. See also the sparse, paired mesosomal pilosity of the mesosoma in both major and minor.
