Cernosvitoviella crassoductus Dózsa-Farkas, 1990: 269 –271, figs. 7–10. Timm 1999: 134 –135, 2 textfigs

Material investigated: 3 specimens from site 10 (13.05.2011).

Body 3–4 mm long, 160 µm wide at VIII and 320 µm at XII, segments 19–23. Chaetae sigmoid with nodulus, up to 6–8 per bundle, 44–49 µm long. Brain deeply incised posteriorly, about 120 µm long and 100 µm wide in vivo ( Fig. 9 View FIGURE 9 A). Two pairs primary and two pairs secondary pharyngeal glands. Secondary glands without lobes and larger than the primary glands ( Fig. 9 View FIGURE 9 D). Coelomocytes plum-stone-shaped, 20–26 µm long, transparent, with some refractile granula, but not dark in transmittent light ( Fig. 9 View FIGURE 9 C). Blood light-pink, dorsal vessel origin in XII. The anterior bifurcation in peristomium ( Fig. 9 View FIGURE 9 B). Seminal vesicle absent. Sperm funnels ( Fig. 9 View FIGURE 9 E) small, pearshaped 40–48 µm long and 23–30 µm wide, collars as wide as the diameter of funnel bodies, about 8 µm high. Dilatation of vas deferens proximally just after the funnel, 90–120 µm long and 20–23 µm wide (the diameter of canal 10–13 µm). After the dilatation (i.e. towards male pore) duct about 85–90 µm long and 9 µm wide. Male pore surrounded by a mass of glands about 50–55 µm wide. Spermatozoa 20–23 µm long, heads 10 µm. Spermathecae ( Figs. 1 View FIGURE 1 D, 9F) short, confined to V. Ampullae elongate-oval, 45–55 µm long and 20–22 µm wide, with distinct sperm-containing lumen. Ectal duct 45–80 µm long and 10–14 µm wide, not widened at the orifice.
