Diagnosis.

This species closely resembles L. amplipenne , L. armatum , and L. praelongum in external morphology, but differs in the primary and secondary sexual characters. Males of L. pedale have a large emargination on sternite VIII, where the aforementioned species have small emarginations or none at all. They also lack a dorsal plate of the aedeagus. Females differ from the three aforementioned species by having valvifers and coxites fully divided.
