Abstract

Strelkovimermis arkansensis n. sp. and Hydromermis welchi n. sp. are described from chironomid adults in Arkansas and Minnesota, respectively. The host of the former is Glyptotendipes paripes (Edwards) and of the latter Polypedilum (Polypedilum) nubeculosum (Meigen). Strelkovimernis arkansensis n. sp. most closely resembles Strelkovimermis buccalis Johnson and Kleve, 1996 and is separated from that species by color in the living worms, thickness of the cuticle, and length of the cephalic papillae. Hydromermis welchi n. sp. is similar to Hydromermis gastroviridis Johnson and Kleve, 1997 and is separated from that species by color in the living worms, structure of the spicule, and number of genital papillae. A variant of H. welchi n. sp. is described. Molting in S. arkansensis was apparently facilitated by having both postparasitic males and females in the same vial.

摘要

阿肯色州斯特列尔科线虫新种（Strelkovimermis arkansensis n. sp.）和韦尔奇水线虫新种（Hydromermis welchi n. sp.）分别从阿肯色州和明尼苏达州的摇蚊成虫中被描述出来。前者的宿主是帕氏雕翅摇蚊（Glyptotendipes paripes (Edwards)），后者的宿主是云雾多足摇蚊（Polypedilum (Polypedilum) nubeculosum (Meigen)）。阿肯色州斯特列尔科线虫新种与颊部斯特列尔科线虫（Strelkovimermis buccalis Johnson and Kleve, 1996）最为相似，可通过活体蠕虫的颜色、角质层厚度和头部乳突长度与该物种区分开来。韦尔奇水线虫新种与绿色胃水线虫（Hydromermis gastroviridis Johnson and Kleve, 1997）相似，可通过活体蠕虫的颜色、交合刺结构和生殖乳突数量与该物种区分开来。描述了韦尔奇水线虫新种的一个变种。在同一小瓶中同时存在寄生后的雄性和雌性，显然有助于阿肯色州斯特列尔科线虫的蜕皮。
