Abstract
|
|
|
|
A new species of free?living marine draconematid nematode, Dracogalerus koreanus n. sp., is described from the shallow subtidal coarse sediments and various invertebrates of Jeju Island, Korea. This is the first record of this genus from Korea. Dracogalerus koreanus n. sp. is morphologically most similar to D. cryptocephalus (Irwin?Smith) in having similar head shape (rostrum broadly rounded anteriorly) and eight cephalic adhesion tubes, but differs by the small number of rounded protuberances on the ventral side of non?annulated tail end (5 vs 6), small number of posterior subventral adhesion tubes in male (5?6 vs 8), intermingled somatic setae (5?6 vs absent), spicules (slightly curved and relatively thick vs strongly curved and very slender), and higher “c” value in male (8.8 vs 7.5).
