(Grube, 1879)
Description
Medium-sized worms. Body armoured with dense cover of small, dark, irregularly arranged secretory papillae. Usually two circles of larger secretory papillae on each segment. Dorsal bundles with 1-4 hair chaetae and 1-4 short bifids of obscure shape, the latter usually hidden in the armour. Ventral bundles with 1-2 simple-pointed crotchets, or sometimes, besides them, also finely bifid crotchets, more curved posteriorly. In X, single straight, furrowed spermathecal chaeta per bundle, 145 µm long. No ventral chaetae in XI. Length 18-50 mm, segment number 40-75. Differing from the other European papillate tubificids in having simple-pointed ventral chaetae and spermathecal chaetae (in Haber turquinae, spermathecal chaetae are accompanied with penial chaetae).
