Description
Henlea nasuta (Eisen, 1878) sensu Nielsen & Christensen, 1959
(Figure 17)
Material examined. 25 specimens (three specimens were deposited in the National Institute of Biological Resources, Korea; NIBRIV0000837806 and NIBRIV0000866135, in 70 % ethanol).
Our observations agree with the diagnostic features reported by Nielsen & Christensen (1959), Rota et al. (2018) and others assembled by Schmelz & Collado (2010). Large worms, 15–25 mm long and about 1 mm wide. Segments 48–50. Clitellum girdle-shaped, gland cells in reticulate pattern (Figs 17E, F), penial bulb small (Fig. 17F). Chaetae maximum 7–8 per bundle. Oesophageal appendages spongy, with paired dorsal and ventral lobes in VI, winding canals from VI to IV (Fig. 17D), and in IV a free plurilobed projection middorsally and midventrally (Fig. 17C). Intestinal diverticula two large rounded pouches attached laterally in VIII (Fig. 17A). Dorsal vessel arising in VIII, between intestinal diverticula (Fig. 17A). Five pairs of preclitellar nephridia. Coelomocytes discoid, opaque, with fine brownish granules (Fig. 17B). Sperm funnels about twice as long as wide (Fig. 17G). Spermathecae with pear-shaped ampullae. Ectal ducts long without glands. Ental ducts united before attaching to the oesophagus (Fig. 17H).
