Oecleus
Oecleus is a genus of cixiid planthoppers (Hemiptera: Cixiidae) established by Stål in 1862. Species in this genus have been documented in Brazil, Jamaica, and Costa Rica, with host associations primarily involving palms, particularly coconut (Cocos nucifera) and date palm (Phoenix). Some species have been detected in surveys targeting potential vectors of lethal yellowing disease in palms, though a confirmed vector role has not been established. The genus has been subject to phylogenetic analysis using COI, 18S, and H3 sequence data to clarify relationships within the tribe Oecleini.
