Dominant bristle effect is typical of a H allele; the postvertical and upper humeral bristles are regularly removed and the posterior orbital, posterior vertical, presutural, posterior postalar and anterior dorsocentral bristles are frequently removed. The dominant venation effect is quite distinct from a typical H allele; the veins are not interrupted, instead they are knotted.

Bristle effect like H¹ but venation quite distinct; veins not interrupted but knotted. RK1.
