phenotype: Posterior dorsocentral bristles missing, anteriors rarely; hairs
usually fewer near posterior dorsocentrals; intraocellar hairs invariably
fewer, typically absent. Eyes partly devoid of hairs. ac/ac or ac/+ partially
suppresses h (Sturtevant). Hw/ac = Hw/+ (Sturtevant). RK1.
cytology: Placed in region 1A5-8 on basis of its inclusion in the XD3P element
of T(1;3)sc260-20 = T(1;3)1A8-B1;61A1-2 and in Dp(1;f)sc260-27 = Dp(1;f)1A8-
B1;19F, but not being lost from Df(1)260-5 = Df(1)1A4-5 (Sutton, 1943,
Genetics 28: 210-17).
