Abstract

Ototyphlonemertes longissima sp. nov is described from the South China Sea. The present species, up to 158 mm long, is about three times longer than the longest previously reported individual known in the genus. It possesses a narrow stylet basis, a bulbous proboscis diaphragm, a long middle proboscis chamber, sculptured stylets, polygranular statocysts and excretory tubules, and thus belongs to the O. macintoshi species group. The genetic divergence (average uncorrected p-distance) between O. longissima (representing a unique network in TCS analysis) and the other species (TCS networks) of genus Ototyphlonemertes is 0.135-0.185.

摘要

新种长吻盲纽虫（Ototyphlonemertes longissima sp. nov）是在南海发现的。该物种体长可达158毫米，约为该属此前报道的最长个体的三倍。它具有狭窄的吻针基部、球状的吻隔膜、长的中间吻腔、有雕刻的吻针、多颗粒平衡囊和排泄小管，因此属于麦氏盲纽虫物种组。长吻盲纽虫（在TCS分析中代表一个独特的网络）与盲纽虫属的其他物种（TCS网络）之间的遗传差异（平均未校正p距离）为0.135 - 0.185。
