ETYMOLOGY. — The species name refers to the coloration of the face.

DIAGNOSIS. — Aedeagal shaft with one short subapical process on left side, two long spine-shaped processes below it, and two long spine-shaped processes on opposite right side ( Fig. 8D, E View FIG ).

TAXONOMIC RELATIONSHIPS. — In general the male genitalia structure is close to L. aldabranus Distant sensu Nielson (1982) , but is well differentiated by its black face and details of the aedeagus.
