Description. Lichnia gallardoi closely resembles
Lichnia limbata. Males of L. gallardoi are easily
diagnosed by a shorter antennal club and the presence of a clypeal tooth
(males of L. limbata lack a clypeal tooth). The clypeal tooth
may be worn down and not visible in many specimens. The antennal club
of both males and females of L. gallardoi is small, subequal
in length to segments 3–6 whereas in males of L. limbata
the club is slightly longer than segments 1–6 and the club of
females is as in L. gallardoi. When using male antennal characters
to distinguish L. gallardoi from L. limbata, it must
first be determined that the specimens are males by comparing the protibia,
which is slender in males and expanded along the entire length in females.
Otherwise, males of L. gallardoi can be mistaken for females
of L. limbata because both have short antennae. On average,
both sexes of L. gallardoi are slightly larger than those of
L. limbata. With the exception of size, females of these two
species are indistinguishable and must be identified based on association
with males and geographic location.
