Comprehensive DescriptionRead full entry
DescriptionBody not especially flattened. Lengths 50-80 mm, segments 110–140. First dorsal pore small in 3/4, open from 4/5 onwards. Setae closely paired, ab slightly tumid in some or all of 9-12, 22, 23 and 25,26-32; distinctly paler around cd in just 9 or in some of 9-11,12. Dorsum to below c lines a reddish or pinky puce (sometimes much darker or much paler); ventrum pale with clitellum darker buff, saddle-shaped in 24,25,26,27-31,32,33. TP ½28,28-½31,31. Spermathecae nearly mid-dorsum in 9/10/11. Female pores small on 14 lateral to b. Male pores in slightly tumid pads on 15 lateral of b setae. Nephropores visible sporadically intersegmentally above b lines (alternatively in d?). Internally, spermathecae spherical in 9 & 10. Testis small in 10 & 11, seminal vesicles in 9–12. Last hearts in 11. Calciferous glands annular in 11 & 12. Ovaries in 13. Nephridia sausage-shaped. Crop in 16 and gizzard large in 17-18, with intestine proper after 19; a low, wide typhlosole present from about 26. Remarks: The Jeju specimens lack the supposedly characteristic broad striped appearance while specimen S5 is brick red (mtDNA barcodes show 99% agreement). It seems remarkable that S3-4 would agree as they lack pigment. Other specimens with much darker, almost black, segments and contrasting paler intersegment also comply superficially. The whole species-complex requires evaluation with consideration of ICZN compliance as noted in the Discussion.
