The Manchester United winger will captain Reinaldo Rueda's 30-man selection - which includes Stuttgart youngster Carlos Gruezo - before the final cut is reduced to 23 playersManchester United winger Antonio Valencia headlines Ecuador's provisional squad for next month's World Cup in Brazil.
Head coach Reinaldo Rueda had named a 24-man squad for Ecuador's international friendly against Netherlands on Saturday, but he has added a further six players to finalise his initial selection.
Edison Mendez - Ecuador's third-most capped player in history with 108 - John Narvaez, Michael Arroyo, Oswaldo Minda, Angel Mena and Cristian Penilla have been included alongside captain Valencia.
All nations participating at the World Cup finals are required to submit their official 23-man squads by June 2, though uncapped Stuttgart young-gun Carlos Gruezo is expected to survive the cull.
Cristian Ramirez, Renato Ibarra and Christian Noboa are the only other players from the preliminary selection to be plying their trade in Europe.
Liga MX top scorer Enner Valencia will likely be the focul point in an attack robbed of the talent of Christian Benitez, who died of a heart attack following a cup game for Qatari outfit El Jaish in July last year.
Ecuador will go head-to-head with the Netherlands, Mexico and England in the lead up to Brazil, before opening their World Cup campaign against Switzerland in Group E action on June 15.
France, the 1998 champions, and Honduras complete the group.
