Description
Summary:Plectus cornus Maggenti, 1961. Dimensions of seven females: L = 0.49 - 0.55 mm; a = 26-31; b = 3.6 -4.0; c = 7.7- 8.6; V = 7 - 848 -50 7 - 8. Body curved generally throughout, though less strongly than in P. acuminatus. Cephalic setae 6 \x long,i.e.as long as width of lip region; directed anteriad, the tip bent outward. Lip region somewhat truncate, lips distinct. Ampids questionmark shaped, 1.9-2.4 [x in diameter or 20- 25 % of corresponding body width; located about halfway the mouth cavity. The latter is cylindrical throughout, prostom not widened; 18-19 \L long. Cuticular annulation distinct and rather deep, especially on the tail. Tail length is equal to five or six anal body widths; the tail is bent ventrad in the proximal half, almost straight in the posterior half. These specimens, apart from being smaller, correspond well to the type specimens from Sweden. Sample 44. Published as part of P. A. A.
