wing hinge (with tshae-1)
Heterozygotes for tshae-1 and tsh8.1 show the characteristic abnormal wing and haltere posture, as found in tshae-1 mutants, but the phenotypes also include a number of other thoracic and wing-hinge defects, much like those observed with tsh8. In heterozygotes for tshae-1 and tsh8.1, it appears that, within the mesopleural plate, the pre-alar apophysis is pushed anteriorly towards the vertical cleft. The cuticle of the mesopleural plate on the posterior side of the vertical cleft appears to be forced into the vertical cleft or under the mesopleural plate. There is also a buckling of the cuticle in the suture between the notopleurite and the mesopleural plate.
