DIAGNOSIS.
Laterospinocoris cyaneipennis
(
Figs. 43–45

This species is to similar
L. mexicanus
, but differs in having a uniformly red head (versus red with brown on the frons) and pronotum (versus anterior half of the pronotum brown to dark brown), hemelytra with a distinct bluish sheen (versus a weak bluish sheen and a pale costal margin), and black legs (versus pale yellowish brown legs).
