Abstract / Notes
The umagillid turbellarian Syndesmis evelinae, originally described from unnamed Caribbean sea urchins, is redescribed and placed in the genus Syndisyrinx. Syndisyrinx evelinae n. comb. was found in 8 of 32 (25%) Echinometra lucunter from the Bay of St. Jean, St. Barthelemy; 6 of the 8 (75%) urchins with S. evelinae also had Syndisyrinx collongistyla. The major difference between the original description and the worms described here is the structure of the bursal valve. The valve was originally described as having a thickness between the seminal receptacle and the seminal bursa; in fact, the bursal valve has 2 sclerotized ducts, 1 that enters it from the seminal receptable and another that leads to the bursal canal.
