Achaeta brevivasa Graefe 1980

Achaeta cf. brevivasa Graefe, 1980 (Figure 13, A,B) NIBRIV0000320532, NIBRIV0000320533, slides 1084, 1085. Two adult fixed and stained specimens, collected from site 11. Segment number 20���23, length 3.1���3.5 mm, in vivo, 2.1���2.7 mm long and about 200���210 ��m wide, fixed. Pyriform glands absent, lentiform epidermal glands not detected. Clitellum and male openings in XII. Clitellum with 6 baguette-rows of hyalocytes; between rows, at the edges, granulocytes present (Fig. 13 B). Brain 65���75 ��m long (fixed) and about 1.5 times longer than wide, rounded posteriorly. Coelomocytes rounded, about 44 ��m long. One pair small secondary pharyngeal glands in VI, not well visible. Two pairs preclitellar nephridia in 6 / 7, 7/ 8. Sperm funnels small, 40���50 ��m long and 20���21 ��m wide. Spermathecae in V, about 65���75 ��m long in vivo (Fig. 13 A). The whole mounts are unfortunately not of good quality; secondary pharyngeal glands could not be seen with certainty, and lentiform epidermal glands were not detected, either. For these reasons we added a "cf." to the species name.
