Description (from Thorne, 1939)
Lip region set off by a deep constriction, slightly more than one-third as wide as base of neck. Spear about one-sixth as wide, and one and one-half times as long, as width of lip region, the aperture occupying one-third of its length. Guiding ring double. An elongate swelling surrounds the base of the spear extension. Esophagus enlarged slightly anterior to middle. Intestinal cells with brown granules. Female prerectum length one and one-half times anal body diameter. Anterior ovary extending almost to base of esophagus, the posterior reaching half way to anus. Supplements 15, slightly separated, the series beginning about half a body width anterior to the spicula. Male prerectum extending to a point about midway of the supplements. Tails of both sexes blunt, rounded, about two-thirds as long as the anal body diameter.
This species is distinctive because of its small size, long ovaries, number and arrangement of supplements and slender spear.
Habitat: Incrustation on stones in water 0.5-1.0 m deep. Central Sumatra, Netherlands East Indies.
