A detailed taxonomic study on two new and one known species of Anaplectus De Coninck & Schuurmans Stekhoven, 1933 (Nematoda: Plectidae)

This paper provides descriptions of two new and one known species of the genus Anaplectus De Coninck Schuurmans Stekhoven, 1933. Anaplectus sudhausi sp. nov. is characterised by leaf-shaped lips interspersed with interlabial liplets; bifid apices of the lateral lips; cheilostom with non-cuticularised walls; gymnostom with cuticularised arcuate walls; 120-132 sublateral hypodermal glands on each body side with an additional 5-8 smaller subdorsal hypodermal glands; female tail with three caudal setae; males with arcuate spicules having manubrium slightly wider than calomus or blade, last median tubulus or supplement about half the spicule length and tail terminus with a weakly cuticularised spinneret. A. labiosulcus sp. nov. is characterised by 115-123 sublateral hypodermal glands on each side of the body with those on the dorsal side usually larger than the ventrals; the 5-6 anteriormost glands are unpaired and arranged linearly; lips with cuticularised interlabial grooves; gymnostom arched, occasionally double-arched and caudal glands grouped and opening through a cuticularised spinneret. A. granulosus (Bastian, 1865) De Coninck Schuurmans Stekhoven, 1933 has been redescribed with some minor differences from previous descriptions.
