Abstract
Summary Bealius pinus n. sp. is described and illustrated based on its morphological, morphometric, and molecular characters. The new species is characterised by a body length of 1040 (920-1124) μm (females) and 985 (990-1043) μm (males), lip region continuous, 7.2 (7.0-8.0) μm broad, 3.3 (3.0-4.0) μm high, stylet length 8.4 (7.0-9.0) μm or ca 1.0-1.3 times the lip region diam., lateral fields with five or six incisures, the outer incisures crenate and inner incisures weakly crenate, and excretory pore situated 156 (141-170) μm from the anterior end. The basal pharyngeal bulb has a short posterior extension projecting dorsally into the intestine. Post-uterine sac absent. Functional males common in the population, spicules 29 (28-30) μm long. Tail cylindrical with broadly rounded terminus in the female and conical, arcuate, completely enveloped by a well-developed bursa in the male. The new species is compared with two known species of the genus, B. bisulcus and B. pissodi. Molecular phylogenetic studies of the new species using partial sequences of small subunit (SSU) rDNA revealed that it forms a clade with several nematode species belonging to genera in the Sphaerularioidea, namely: Sphaerularia, Paurodontella, Nothotylenchus, and Deladenus.
