Diagnosis. Recognized by the very small size (length ca. 1.35–1.75 mm ); the rather flattened body form; the tenarticled antenna (five + club); the lack of an hypomeral carina; the hypomeral antennal pocket setae forming a strong cup; the weakly developed ocelli located between the midline and the eyes; and the transverse pronotum with anterior hyaline margin and lacking postocular emarginations. Refer to Perkins (2009) for comparisons with other genera of Parhydraenini . The two new species described herein brings the total to five in Madagascar. There is one described species each from Namibia and Tanzania ( Perkins 2009 ). The Tanzanian species is morphologically distinct in some characters, and preliminary DNA sequence data suggest that it might represent a separate genus ( I. Ribera , pers. com.).
