초록
We report Ptycholaimellus ocellatus Huang and Wang, 2011, a free-living marine nematode of the family Chromadoridae Filipjev, 1917, as a newly recorded species in Korea. The specimen was collected from intertidal sediment habitats along the southern coast of Korea. Ptycholaimellus ocellatus is characterized by a distinct set of morphological features, including an abruptly tapered cervical region, the presence of ocelli, a transversely striated cuticle with lateral differentiation marked by two prominent longitudinal rows of dots, a large ampulla within a voluminous ventral gland, and two pharyngeal bulbs. This study provides the first taxonomic report of the genus Ptycholaimellus in Korean waters with differential interference contrast (DIC) and scanning electron microscopy (SEM) micrographs.
Abstract
We report Ptycholaimellus ocellatus Huang and Wang, 2011, a free-living marine nematode of the family Chromadoridae Filipjev, 1917, as a newly recorded species in Korea. The specimen was collected from intertidal sediment habitats along the southern coast of Korea. Ptycholaimellus ocellatus is characterized by a distinct set of morphological features, including an abruptly tapered cervical region, the presence of ocelli, a transversely striated cuticle with lateral differentiation marked by two prominent longitudinal rows of dots, a large ampulla within a voluminous ventral gland, and two pharyngeal bulbs. This study provides the first taxonomic report of the genus Ptycholaimellus in Korean waters with differential interference contrast (DIC) and scanning electron microscopy (SEM) micrographs.
