Six segmental epidermal gland cells, three on each side, in bilateral-symmetrical arrangement, cells larger than clitellar hyalocytes, up to twice as thick as body wall, outline circular or oval, diameter ca. 15 μm (fix); dorsally 4 cells in one transverse row, cells aequidistant from each other, slightly larger than ventral cells, ventrally one segmental pair in usual position, in row directly posterior of dorsal glands, directly anteriorly of septum. Body wall very thin (2–4 μm, fix), longitudinal muscle layer 1 μm thick or less, cuticle barely visible.

Suboesophageal ganglion present, ventral nerve cord in segmental ganglia from V on. Oesophageal appendages as two sausage-like bodies in V, lining oesophagus laterally, diameter 14 μm (fix), circular in optical cross-section, connected by a mid-dorsal strand of about same diameter, no canal seen in IV.

Dorsal blood vessel from VII, large, pulsating. Pars tumida of midgut not seen. Two pairs of preclitellar nephridia, at 6/7, 7/8; anteseptale about as wide as long, truncate, postseptale gradually tapering towards ectal pore, no terminal vesicle; shape of postclitellar nephridia alike.

Three longitudinal rows of hyaline gland cells on each side of dorsal half: First row truly dorsally, distance between rows of both sides not more than one cell diameter; row regular, consisting of 14-15 cells, all one behind the other; further down laterally 2 disordered rows of hyaline cells, cells not in straight line. Latero-ventrally only granulocytes, about half as wide as hyalocytes. Hyalocytes not projecting beneath muscle layer into body cavity, as high as long (ca. 8 μm), width up to 20 μm. Seminal vesicle absent. Spermatozoa short, measured head length 8 μm (fix). Sperm funnel small, collar narrower than funnel body, asymmetrical (28µm: 20 μm and 28 µm: 12 μm in the same animal, fix). Vas deferens narrow, with few coils, not straight. Male pore on body surface, surrounded by a compact gland, more or less spherical in side view, diameter 16 μm (fix). Accessory glands absent. Spermatheca very small, confined to V, ectal pores lateral, cuticularized ectal duct not seen, sperm in parallel at ca. 15–20 μm distance proximally of ectal pore, ental reservoir not thickened compared to rest of organ.
