Female:
General description: Body length 9.36 mm, body black with white apical pubescent bands on metasoma.
Colour: Body black with white shiny pubescence on face and white apical pubescent bands on metasomal segments.
Head: Shiny white pubescence on face; labrum with pale white pubescence; clypeus roughly punctate and without median longitudinal line, basally produced into a prominent triangular ridge, apically curved with intermixed large fulvous pubescence; F1 equal to pedicle and approximate double the length of F2.

Metasoma: T1 covered with sparse long white hairs; T2-T5 apical margin with white fasciae, interrupted in the middle of T1; T4 and T5 with black erect hairs sparsely distributed; T6 covered with dense sub erect black hairs; pale white sternal scopa on S2-S5.
Male:
General description: Body black, body length 8.96 mm, smaller than female; similar to female but tubercles on tibia not as much developed as in female; mesosoma with pale white pubescence; T1 with long fasciae at appeal margin, without interruption in middle as female; T2-T5 with small hair bands at the apex; pygidial plate present.
Colour: Body black with white shiny pubescence on face and white apical pubescent bands on metasomal segments..
Genitalia: Much broader volsella which covered 3/4th of genitalia; gonostylus narrow with slightly dilated at the distal end, small and covered with pubescence.

This species has similarity with L. atratus Smith by body size, colour and pubescent band on metasoma but found differ in following characters: female with pale white sternal scopa which is black in L. atratus Smith; shape of male genitalia slightly differ in the structure of volsella, which is little narrower than the volsella of L. atratus Smith.
