Abstract

Two nematode species of the genus Enchodelus Thorne, 1939, one new and one known from Arctic polar deserts were studied. Enchodelus makarovaesp. n. is an amphimictic species, characterised by females with body length of 1.57-2.00 mm, lip region 15-17.5 µm wide, amphid duplex, odontostyle 38-43 µm long or 2.3-2.8 times lip region diam. Odontophore with flanges, 1.2-1.4 times as long as odontostyle; pharynx length 320-377 µm, pharyngeal expansion 113-130 µm long or 32-37% of total pharynx length; female genital system amphidelphic, uterus tripartite, pars refringens vaginae with two trapezoid sclerotisations, vulva a transverse slit (V=45-51%); tail bluntly conoid (25-35 µm, c=45.8-70.3, c'=0.6-0.9 in females, and 29-33 µm, c=46.4-58.9, c'=0.7-0.8 in males). Males with 65-74 µm long spicules and 10-12 spaced ventromedian supplements. Additional information for Enchodelus groenlandicus is provided, this being a new geographic record for the Putorana Plateau, Russian Arctic.

摘要

对索恩1939年命名的恩乔德线虫属的两个线虫物种进行了研究,其中一个是新物种,另一个来自北极极地沙漠且已知。新物种马卡罗娃恩乔德线虫是两性融合物种,其特征为:雌虫体长1.57 - 2.00毫米,唇区宽15 - 17.5微米,双套化感器,口针长38 - 43微米或为唇区直径的2.3 - 2.8倍。具翼状突的咽管,长度为口针的1.2 - 1.4倍;咽长320 - 377微米,咽扩张部长113 - 130微米或占咽总长的32 - 37%;雌性生殖系统为双子宫型,子宫分三部分,阴道折射部有两个梯形硬化,阴门为横向裂缝(V = 45 - 51%);尾部钝圆锥状(雌虫尾长25 - 35微米,c = 45.8 - 70.3,c' = 0.6 - 0.9;雄虫尾长29 - 33微米,c = 46.4 - 58.9,c' = 0.7 - 0.8)。雄虫具长65 - 74微米的交合刺和10 - 12个间隔的腹中线副附器。还提供了格陵兰恩乔德线虫的更多信息,这是俄罗斯北极地区普托拉纳高原的新地理记录。
