Teklehaimanot will be joined by Victorians Simon Clarke and Mitch Docker and Western Australian Travis Meyer for their first Grand Tour starting in Pampalona on Saturday.
Allan Davis, Cameron Meyer, Julian Dean, Pieter Weening and Wesley Sulzberger are also on the team.
Teklehaimanot, 23, is from Eritrea and in his first season on the WorldTour.
He joined Orica-GreenEDGE for its maiden season and his progress has impressed general manager Shayne Bannan.
"We're really happy with him,'' Bannan said.
"He held the mountains jersey until the final day at the Tour of Poland and has been training strongly ever since.
"For him to be selected for a Grand Tour in his first year indicates the type of faith we have in him for the future.''
Bannan said his Vuelta team would showcase some of its emerging talent but did not have ambitions for overall victory.
"We've got a really good mixture of experience and knowledge, combined with some talented young riders,'' he said.
"It will be about taking our opportunities, for guys like Cam Meyer it will be about being as consistent as possible but there's certainly no pressure on him for GC (general classification).
"Pieter Weening will have a go in a few stages and so will Simon (Clarke) and Allan (Davis).''
The Vuelta a Espana, the third and final Grand Tour of the season, runs from August 18 to September 9.
Alberto Contador is expected to start a strong favourite to win the race after returning to cycling at last week's Eneco Tour following his drug ban.
