Comment

Besides the species of Libitioides , there are unpublished records which should probably belong to C. quadrispinosa from the southeastern tip of Florida, around Miami City. The more typical species of Cynortoides hail from Cuba, while there are at least four others in Jamaica and Hispaniola which resemble more closely this Floridan cosmetid. Those Jamaican/Haitian/Dominican species are poorly studied, some only known from the female holotypes, therefore, it is not possible for now to use masculine sexually dimorphic features to look for identification clues. Due to the gap in distribution between these species, it is likely that the USA specimens are introduced from the Greater Antilles.
