Abstract

Three new species of Aporcelaimoides from natural habitats in Vietnam are studied, described and illustrated, including line drawings, LM and/or SEM pictures. Aporcelaimoides brevistylum sp. n. is characterized by its body 1.95-2.90 mm long, lip region offset by deep constriction and 17-18 mu m broad, ventral side of mural odontostyle 11-14 mu m long with aperture occupying 62-71% of its length, neck 663-767 mu m long, pharyngeal expansion occupying 58-66% of total neck length, uterus a simple tube 85-182 mu m long, pars refringens vaginae absent, V = 55-63, tail short and rounded (34-46 mu m, c = 49-76, c' = 0.6-0.8), spicules 67-86 mu m long, and one ventromedian supplement out the range of spicules. Aporcelaimoides minor sp. n. is distinguished in having body 2.09-2.61 mm long, lip region offset by deep constriction and 19-20 mu m broad, mural odontostyle 14-16 mu m long at its ventral side with aperture occupying 73-84% of its length, neck 579-649 mu m long, pharyngeal expansion occupying 57-66% of total neck length, uterus a simple tube 44-69 mu m long, pars refringens vaginae well developed, V = 48-56, female tail very short, rounded conoid or truncate (14-26 mu m, c = 90-146, c' = 0.3-0.6), and male unknown. Aporcelaimoides silvaticum sp. n. is characterized by its body 2.09-2.60 mm long, lip region offset by depression and 17-18 mu m broad, mural odontostyle 11-12 mu m long at its ventral side with aperture occupying 60-66% of its length, neck 597-720 mu m long, pharyngeal expansion occupying 58-64% of total neck length, uterus a simple tube 128-243 mu m long, pars refringens vaginae well developed, V = 58-60, tail short and rounded (27-37 mu m, c = 67-94, c' = 0.6-0.7), spicules 64-75 mu m long, and two or three widely spaced ventromedian supplements bearing hiatus. The genus Aporcelaimoides is restored, its diagnosis emended, and three species of Sectonema, namely S. amazonicum, S. haguei and S. moderatum, transferred to it. An updated list of its species, a key to their identification and a tabular compendium with the most important morphometric features are also presented.
