Compound tarsus seen in T1-4. In Dlbl5/DlblX59 adults, mutant legs develop presumptive borders of leg joints, but do not display growth segmentation and cell shape changes. Occasionally minor duplication of the sex comb is also seen. In the head segment, loss of the basal cylinder in the antenna is seen. DlFE32/DlblX59 mutants show a multiplication of sex combs on the first tarsal segment.
