Syn. (Plectoides) de Man, 1904
Pycnolaimus Cob, 1920
Anaplectus de Coninck & Schuurmans Stekhoven, 1933
“Definition: Plectinae. Cuticle with transverse striae and scattered fine bristles. Lateral fields present. Head more or less distinct and offset by the slight constriction. 6 lips; 4 cephalic setae just behind the level of the head. Amphid openings, ring-like or elliptical. Stoma, tubular and lined with rod-like rhabdions. Oesophagus almost cylindrical, tapering slightly to the isthmus and ending in a muscular bulb containing a tri-radiate, denticulate valve apparatus. Nerve ring crossing isthmus about madway of its length. Excretory pore leading to a twisted excretory duct which joins a nucleated excretory cell lying ventral to the oesophagus. (Bastian based the name Plectus on the twisted nature of the excretory duct.) Tail containing 3 caudal glands, which open at the tip through a terminal duct. Female: Vulva equatorial, gonads paired, opposed and reflexed. Male: Where known, with 2 testes, anterior and posterior, opening into a single vas deferens; spicules paired but asymmetriacl, gubernaculus complex. A row of ventral tubular supplements sometimes present. Pre-anal ventral setae may be present.
Maggenti (1961) revising the genus recognizes Anaplectus as a separate one, but gives no reasons for this action. De Coninck & Schuurmans Stekhoven (1933) erected Anaplectus for those species with 4 cephalic setae and tubular supplements on the male. However, Plectus parietinus, the type of Plectus, has both characters.” From Goodey 1963 and Powers and Mullin website http://nematode.unl.edu/
