Distribution of Lichnia gallardoi.

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.

Distribution. Region IV (Coquimbo) of Central Chile.

Phenology: September through January with a climax in numbers in October.
