Each of the recovered species was characterized based on morphology and molecular data using rRNA gene sequences. <jats:italic>Trichodorus hangzhouensis<\/jats:italic><jats:bold>sp. nov.<\/jats:bold> is characterized by its males having medium-sized onchiostyle (46\u201349 \u00b5m) and three ventromedian cervical papillae (CP) anterior to the secretory-excretory (S-E) pore, CP1 located opposite the anterior part of isthmus, S-E pore opposite the isthmus or anterior end of pharyngeal bulb, spicules slightly ventrally curved, relatively small, 33.2 (32.0\u201334.5) \u00b5m long, wider slightly marked capitulum, lamina partially striated without bristles at striation; and females having rounded triangular sclerotized vaginal pieces with tips directed towards vulva, 1.5\u20132.0 \u00b5m sized, at about 1 \u00b5m apart, vulva pore-like in ventral view.
