The third seeded Indo-Zimbabwean pair suffered a tame 3-6 2-6 defeat in under an hour contest against the Australian-Croatian combination.
Sania and Cara, who ended the 2013 season by winning back-to-back titles in Japan and China, could convert just one of the six break chances they got while dropped their service games twice in each set.
Jarmila and Ajlaat hit four aces to one of their rival and committed one double faults to three of Sania and Cara.
Sania and Cara will now compete at the first Grand Slam, the Australian Open, from Monday.
