The 33-year-old Younus was not selected despite his indefinite ban -- imposed in March over "infighting in the team" -- being lifted earlier this month. Pakistan Cricket Board (PCB) has not given clearance for his selection.
Younus was one of seven players banned and fined following Pakistan's disastrous tour of Australia, where the team lost all three Tests, five one-dayers and a Twenty20 game.
Pakistan Sunday announced two different squads for the Twenty20 matches and Tests on the upcoming tour of England.
The 15-man Twenty20 squad includes Shoaib Akhtar but the express paceman was excluded from the 17-member Test squad.
Akhtar, who has not played a Test since December 2007 due to fitness and discipline problems, is part of the team which is featuring in the ongoing Asia Cup in Sri Lanka.
Leg-spinner Danish Kaneria was included in the Test squad despite being under investigation by Essex Police on charges of spot fixing. He was, however, cleared by England and Wales Cricket Board to play.
Pakistan will play two Twenty20 internationals against Australia on July 5 and 6 before playing two Tests against the same opponents.
After playing Australia, Pakistan will feature in four Tests, two Twenty20 and five one-day games against England. The tour ends on September 22.
The squad for the one-dayers against England will be announced later.
Squad: (Twenty20): Shahid Afridi (capt), Salman Butt (vice capt), Shahzaib Hasan, Umar Akmal, Shoaib Malik, Umar Amin, Kamran Akmal, Abdul Razzaq, Mohammad Amir, Umar Gul, Saeed Ajmal, Shoaib Akhtar, Abdul Rehman, Wahab Riaz, Fawad Alam
