Abstract

In the summer of 2003, chironomid imagoes eclosing from Lake Alice Bog in Minnesota yielded mermithid nematodes of 2 new species. Lanceimermis palustris n. sp. is distinguished from the other 14 species of the genus by the subventral mouth position, thinness of the hook-shaped spicule, body index, and structure of the male tail muscles. Telomermis palustris n. sp. is distinguished from the only other species of the genus by the structure of the amphids, body length, maximum body width, length of the esophagus, and the presence of a minute larval terminal horn. Lanceimermis palustris n. sp. hosts were Chironomus maturus Johannsen and T. palustris n. sp. hosts were Tanytarsus mendax Kieffer, Paratanytarsus nr. dissimilis n. sp., and Micropsectra polita (Malloch). In both mermithid species, the percent of mermithid males per host increased with the intensity of the infection.

摘要

2003年夏天，从明尼苏达州艾丽斯湖沼羽化出的摇蚊成虫体内产出了2个新种的索线虫。沼泽矛线索线虫新种（Lanceimermis palustris n. sp.）与该属其他14个物种的区别在于口位于腹面亚侧、钩状交合刺细、身体指数以及雄性尾部肌肉结构。沼泽端线索线虫新种（Telomermis palustris n. sp.）与该属唯一的另一个物种的区别在于头感器结构、体长、最大体宽、食管长度以及有微小的幼虫端角。沼泽矛线索线虫新种的宿主是成熟摇蚊（Chironomus maturus Johannsen），沼泽端线索线虫新种的宿主是隐匿摇蚊（Tanytarsus mendax Kieffer）、近异摇蚊新种（Paratanytarsus nr. dissimilis n. sp.）和精致微摇蚊（Micropsectra polita (Malloch)）。在这两种索线虫中，每个宿主体内索线虫雄虫的百分比随感染强度增加。
