Genus Photolateralis

Species in the genus Photolateralis are differ from other leiognathids in having a translucent flank stripe, which may be comprised of either a continuous mid-lateral stripe or a composite stripe comprised of numerous independent translucent windows. The translucent lateral stripe is either lacking entirely in females, or is considerably less developed. Photolateralis differs from the sister genus Equulites, in the morphology of the light-organ system.
