      Classifiable in single dose triploids.

      (Schultz, 1934)

      Wings often compressed into narrow strips, sometimes filled with fluid. Alula larger and square tipped with clumped bristles and bare regions. Alula modification is characteristicly least likely to overlap wild type. Completely overlaps wild type at 19oC, almost never at 28oC or 30oC. Not lethal when homozygous; viability, as in heterozygote, about 70% wild type. RK1 at 28oC-30oC; RK2 at 25oC.
