title: Description of a New and Two Known Species of the Free-living Nematode Paroigolaimella Paramonov, 1952 (Diplogastridae) from India.
abstract: This paper describes a new and two known species of Paroigolaimella collected from India. Paroigolaimella helalii n. sp. is characterized by having conspicuous sexual dimorphism in the stoma and pharynx, ovaries with a sphincter separating the mature oocyte from developing ones, a vagina leading to a strong ovijector, a pore-like vulva with cuticular flap; males with slender strongly arcuate spicules with dilated capitula; the gubernaculum slender with expanded plate-like distal end and nine pairs of genital papillae, and four to five pairs of copulatory muscle bands. P. coprophila (Sudhaus and Rehfeld, 1990) Sudhaus and Fürst von Lieven, 2003 collected from leaf litter from a farmyard has been redescribed with reassessment of its distinguishing characters from P. bernensis. P. bodamica (Micoletzky, 1922) n. comb. has been described and its status has been discussed with context to P. bernensis.
