Morphometrics and molecular analysis of the free-living nematode, Belondira bagongshanensis n. sp. (Dorylaimida, Belondiridae), from China
AbstractA new species, Belondira bagongshanensis n. sp., extracted from soil under grass in Bagongshan Forest Park, Anhui Province, China, is described and illustrated. The new species is mainly characterized by a body length 1.6–2.1 mm; cephalic framework moderately sclerotized; odontostyle robust with a distinct lumen; anterior part of pharynx with a distinct fusiform swelling, bearing distinct sclerotized valve plates and basal expansion occupying about three-fifths of the total neck length; female genital system mono-opisthodelphic and anterior branch 0.8–1.6 times the corresponding body diameter; tail short and hemispheroid; male spicules 36–49 μm long and two widely spaced ventromedian supplements. The new species is close to B. wajahati, B. golden and B. eugeniae in possessing a short tail, a robust odontostyle with a distinct aperture and a moderately sclerotized cephalic framework. New sequences of 18S rDNA and the D2–D3 region of 28S rDNA of the new species were also identified.
