Sister to S. caudacutus. Substantial individual variation in characters used to define races; all noted differences might be due to combination of clinal and individual variation, making recognition of races inappropriate; ennosiphyllus intergrades with salvini in Atrato Valley (Colombia). Three subspecies currently recognized.
