Gardner, leg. [NHMUK], additional paratypes: same data [NHMW], same data except 5.XII.1955 [NHMUK]. Diagnosis. Body length 3.3–3.4 mm, 2.0–2.1 × as long as wide. Female frons simple, finely reticulate and dull from vertex to epistoma, with short erect setae evenly distributed; underside of head (gular area) with a tuft of forward pointing setae; antennal club with two clearly visible, asymmetrically procurved, almost angular, sutures; vestiture on pronotum and elytra similar; elytral interstriae on declivity increasingly granular towards posterior margin. Distribution: Tanzania. Host plant: Kuloa usambarensis (Lauraceae). Remarks. This species is only known from the type locality and is the only East-African representative of the genus.
