Diagnosis

Coloration coffee brown spotted with black. Face of head pale brown, maxillary plates whitish; vertex, including crown, transversely striated. Pronotum slightly widest posteriorly, laterally carinate and transversely striated, coffee brown mottled with differently shaped black spots. Tegmen, including veins, hyaline coffee brown with evenly distributed large black spots. Length ♂ 5 mm, greatest width 1.8 mm (Evans 1972).

Vertex and forewings speckled with small variably shaped and sized dark brown spots. Vertex flattened and with slight ridge around anterior margin; forewing venation normal with 1–2 additional crossveins on costal margin adjacent to outer subapical cell. Male pygophore processes short, robust, directed posteriorly at base then turned abruptly dorsally with a posteriorly directed, lamellate, foot-shaped expansion subapically on posterior margin. Subgenital plates as in lavinia. Styles with apical process elongate, slender, of uniform width, tapering distally to acute upturned apex; ventral margin with a small spine at midlength. Aedeagus with shaft slender, directed dorsally, a pair of posteriorly directed lamellate expansions subapically on lateral margin and another laterally directed pair apically; gonopore extending to near midlength of shaft; anterior incision very short. Length ♂ 5.25 mm (Knight 1983).
