无刺伞滑刃线虫sp.的形态特征和分子特征进行了描述和分类。该新种属于该属的木虱组，其特征是分泌-排泄孔位于中球稍后，稍细，雌性尾较宽而直，末端形状多样，雄性囊瓣圆形，末端方形。新物种在遗传学和生物学上最接近B。luxuriosae。这些神秘的物种共享的主机（栖息地）树种，龙牙木（五加科），相同的载体昆虫物种，Acalolepta luxuriosa（Cerambyariae），和一个特征phoretic成人的形式。然而，新物种是从所有其他的木麻黄组物种的类型学区分的上述特征和分子图谱（SSU和LSU分子条形码）的组合。此外，B.无盖层; sp.可以与其最近的亲戚B区分开来。luxuriosae，通过交配实验，即，这两个物种在相互杂交中没有产生可存活的F1代，从而使用生物物种概念确认了单独的物种状态。
Bursaphelenchus acaloleptae n. sp. is described and figured based upon its morphological characters and molecular profiles. The new species belongs to the xylophilus-group of the genus and is typologically characterised by its secretory-excretory pore being located slightly posterior to the median bulb, weakly tapering, relatively broad and straight female tail with variously shaped terminus, and rounded male bursal flap with squared terminus. The new species is phylogenetically and biologically closest to B. luxuriosae. These cryptic species share the host (habitat) tree species, Aralia elata (Araliaceae), the same carrier insect species, Acalolepta luxuriosa (Cerambycidae), and a characteristic phoretic adult form. However, the new species is typologically distinguished from all other xylophilus-group species by the combination of the above-mentioned characters and molecular profiles (SSU and LSU molecular barcodes). Further, B. acaloleptae n. sp. can be distinguished from its closest relative, B. luxuriosae, by mating experiments, i.e., these two species did not produce a viable F1 generation in reciprocal crossings, thereby confirming separate species status using the biological species concept.
