Two new species of Encyclia llooker(Orchidaceae: Iaeliinae) are proposed from Vene-zuela. E. bel tancourtiana Carnevali & I. Ramirezand E. garciae-esquivelii Carnevali & I. Ranifrez.The first, from Andean Venezuela, is related to E.aspera. but has a subquadrate labellum and growsat higher elevations. The second, from the northernslopes of the Coastal Range. is related to E. diurnabut has smaller, differently colored flowers, a moreelliptic central lobe. and grows in coastal thorn for-ests.REst IMtN. )os nuevas especies de EnlccliaHooker (Orchidaceae: Laeliinae) de Venezuela seproponen.

The genus was then reviewed by Carnevali and Iamfrez (1988, as Encyclia) and later by Carnevali et al. (1994). These last two treatments included within Encyclia the species that were recently segregated as the genus Prosthechea Knowles & Westcott by Higgins (1998). An overall, encyclopedic view of the South American species of the genus was presented by Withner (2000), who essentially treated the Vene-zuelan species following Carnevali et al. (1994). This author for the first time explicitly excluded the Prosthecheal taxa from Encyclia in a generic treat-ment. IRomero and Carnevali (2000) added two En-cyclia species for Venezuela in their new edition ofI)uusterville and Garay's Orchid of Venezuela: AField Guide. The Encyclia species from the Vene-zuelan Guayana were recently treated by Carnevaliand Ramnirez (2003). Among all these treatments,we can account to date for 16 Encyclia species inVenezuela. Since there have been several range ex-tensions. circumscription changes, and additions inthe genus for the Venezuelan flora, we have starteda new study that will deal with these problems toeventually result in a new revision of the genus forthe country. In this paper, in preparation for the larger over-view of Venezuelan Encyclia, we propose two newslecies, raising the number of known Venezuelanmembers of the genus to 18. The first new species,Encyclia betancourtiana, is the result of the recentcollection of a hitherto unrecorded nmember of theE. aspera (Lindley) Schlechter group, a compllex ofAndean members of the genus. The second newspecies, Encyclia garciae-essquivelii. is the result ofa study of the variation within the broad circum-scription of E. diurna (Jacquin) Schlechter takenby previous authors (e.g., Foldats. 1970; Carnevali& Ramirez, 1988; Carnevali et al., 1994).Eneyclia betaneourtiana Carnevali & I.
