Diagnosis. Lustrina is characterized by the combination of the following characters: tarsal claws bifid, with broad, subparallel tooth; mesonotum with dense, deep and contiguous punctures; forewings with two dark brown bands, one basal and one subapical; wing microtrichia long and thick; legs entirely reddish-testaceous, including coxae; metasomal colouration metallic and transversally banded; body and legs covered by elongated, thick and greyish setae. The combination of the following morphological characters is also considered distinctive, even if some characters are shared with few Cleptes species groups: POL less than 1.0 MOD; pronotum with transverse basal pit row, with large, subquadrate pits, extending to basolateral margins; mesopleuron with ill-defined scrobal sulcus extended horizontally, formed by enlarged and irregular foveae; smaller irregular foveae continue almost forming a loop as in the Cleptes asianus group; metanotal anteromedian pit present; metasomal punctation dense and deep on the second and third tergum.

Distribution. The only known species, Lustrina assamensis , is distributed in the Oriental region from India (Assam) to Vietnam.
