Abstract

Pungentus porosus n. sp. is described and illustrated. The differential characters are a short odontostyle of 6-8 [mu]m or slightly less than one head width, vulva at 44-50%, goblet-shaped amphids, presence of a prevulval uterine sac, and a hemispherical tail with a variable number of pores. Pungenlus sublatum, P. vesiculosus, P. orthocephalus, P. granosus, and P. parvus sensu Eroshenko are considered to be incertae sedis. A key is provided to the 21 valid species of Pungentus. The following species are new Canadian records: P. angulosus, P. clavatus, P. engradinensis, P. marietani, P. microdentatus, P. monohystera, P. obscurus, P. parvus, P. pungens and P. silvestris. Key words: Pungentus, new species, taxonomy, key.
