报道了朝鲜海峡一新种——大针尖峡鹬。该新种的特征是有16个平突，有8个、4个或2个节状突起，雌性只在1至9节上有中背和侧腹针状刺，在2节上有侧腹尖刺，在4和5节上有侧腹尖刺，在两性中都有8和9节。此外，新种的独特之处在于在第7节和第8节上存在成对的腹内附肢，在第9节上存在巨大的腹内感觉点，以及由一个三角板和一个胸骨板组成的末端节。本文首次详细描述了1969年的Condyloderes Higgins属的口锥和内向枢枢。本研究揭示了该属与Campyloderes Zelinka， 1913的种在若干形态特征上的相似性。
A new kinorhynch species, Condyloderes megastigma sp. nov., is described from the Korea Strait. The new species is characterized by the presence of 16 placids with either eight, four, or two knobby projections, middorsal and lateroventral acicular spines on segments 1 to 9, lateroventral cuspidate spines on segment 2 in females only, but otherwise lateroventral cuspidate spines on segments 4 and 5, and 8 and 9 in both sexes. Unique for the new species is furthermore the presence of paired ventromedial appendages on segments 7 and 8, giant ventromedial sensory spots on segment 9, and a terminal segment consisting of one tergal and one sternal plate. The mouth cone and introvert armature are described in detail for the first time for the genus Condyloderes Higgins, 1969. This study reveals similarities in several morphological characters between this genus and species of Campyloderes Zelinka, 1913.
