Furcated setal shafts
Replication of the setal shaft can occur once or more than once. In bifurcated setae the shaft is duplicated. Trifurcated setae have a shaft branched in three shafts. Palmate setae have more then three replications of the shaft that originate at the same location of the shaft. A branched seta has random furcifications that can have subfurcifications.
