Material examined
.
7 specimens
(three were deposited in the
National Institute of Biological Resources
,
Korea
; NIBRIV0000837804, NIBRIV0000866131, NIBRIV0000866132, in 70 % ethanol)
.
Our observations agree with the description of
Nielsen & Christensen (1959)
. Small worms (
3–5 mm
long, 230–250 μm wide at XII
in vivo
), segments 24–27. Chaetae straight, 2–3 per bundle. Clitellum saddle-shaped, gland cells in rows (
Fig. 19C
), glands absent midventrally. Brain incised posteriorly (
Fig. 19A
). Pharyngeal glands all separate dorsally, with ventral lobes, in
VI
largest (
Fig. 19D
). Coelomocytes oval 18–24 μm long, pale, finely granulated (
Fig. 19B
). 4 pairs of nephridia preclitellarly at 6/7–9/10. Dorsal blood vessel from XIII, blood colourless. Sperm funnels small, pear-shaped, 37–50 μm long, 1.5 times longer than wide (
Fig. 19E
). Penial bulbs small, compact (
Fig. 19F
). Spermathecae (
Figs 19
G–H) with elongated ampulla, merging proximally and attached to oesophagus. Ectal ducts narrow and bearing at the ectal pore some glands of different size. One mature egg at a time (
Fig. 19F
).
