A new species of mermithid nematode, Hexamermis eurygasteri n. sp. (Nematoda: Mermithidae) is described as a parasite of the sunn pest Eurygaster integriceps Puton (Hemiptera: Scutelleridae) in Turkey. The combination of the following characters separate H. eurygasteri from other members of Hexamermis Steiner, 1924, as defined by Artyukhovsky (1990) and Kaiser (1991): amphidial pouch integrated into lateral cephalic papillae; amphidial openings minute; well-developed cuticular vulval cone; small vulval lips; vagina straight or slightly curved at tip, without reverse bend; spicules shorter in length than body diameter at cloaca; spicules straight, except occasionally for short bend at base; spicule tips bluntly rounded; and two double rows of genital papillae. This is the first description of a nematode parasite of a member of the Scutelleridae and the first description of a mermithid nematode from Turkey. This mermithid has potential as a biological control agent in an integrated control programme of the sunn pest.
描述了一种新的索线虫目线虫，宽盾蝽索线虫Hexamermis eurygasteri n. sp.（线虫纲：索线虫科），它是土耳其宽盾蝽Eurygaster integriceps Puton（半翅目：盾蝽科）的寄生虫。根据阿尔秋霍夫斯基（1990年）和凯泽（1991年）的定义，以下特征组合将宽盾蝽索线虫与1924年施泰纳描述的索线虫属其他成员区分开来：头感器囊融入侧头乳突；头感器孔微小；角质化的阴门锥发达；阴门唇小；阴道直或顶端稍弯曲，无反向弯曲；交合刺长度短于泄殖腔处的身体直径；交合刺直，基部偶尔有短弯曲除外；交合刺尖端钝圆；以及两排双列生殖乳突。这是盾蝽科成员的线虫寄生虫的首次描述，也是来自土耳其的索线虫目线虫的首次描述。这种索线虫在宽盾蝽的综合防治计划中具有作为生物防治剂的潜力。
