蛇颈龙gen. n.(模式种：P. obtusus （Allen, 1957）梳子。（n.）在长尾蛛科中，长尾蛛属的5个纲中被提出，它们的侧田有4个切口和钝圆的环状雌尾。重新定义了长颈蛇目、窄感蛇目和长颈蛇目，并描述了产自巴西的长颈蛇目。螟蝇属和螟蝇亚科。来自美国路易斯安那州的M. hollisi sp. n. （Dolichodoridae）具有三个切口的侧场，圆形头部缺乏强烈的硬化，长23-26 μm的弱矛，未硬化的阴道，细长的圆锥状微圆的雌性尾巴和三叶滑囊。在尾端异常增厚的角质层在雌鱼中是半球形和环状的，唇环没有纵向凹痕，硬化的头状框架和结实的矛；描述了来自葡萄牙的A. amplus sp. n.（模式种）和A. nectolineatus sp. n.，并提出了7个新组合。Tylenchorhynchus magnicauda （Thorne, 1935）和Tylenchorhynchus graminicola Kirjanova（1951）分别被转移到Amplimerlinius和Merlinius。Micoletzky于1925年提出了一种新命名为黄鳝科的黄鳝属，并将其归入黄鳝科，提升至黄鳝科。n。
Plesiodorus gen. n. (type-species: P. obtusus (Allen, 1957) comb. n.) is proposed in Dolichodorinae for five spp. of Dolichodorus, sensu lato, which have lateral fields with four incisures and an obtusely rounded, annulated female tail. Dolichodorus, sensu stricto, and Dolichodorinae are redefined and Plesiodorus rostrulatus sp. n. from Brazil is described. Meiodorus gen. n. and Meiodorinae subfam. n. (Dolichodoridae) are proposed for M. hollisi sp. n. from Louisiana, USA which has lateral fields with three incisures, a rounded head lacking strong sclerotization, an attenuated spear 23-26 μm long, unsclerotized vagina, an elongate-conoid minutely rounded female tail and a trilobed bursa. Amplimerlinius gen. n. is recognized among Merliniinae by its abnormally thickened cuticle at the tail terminus which in the female is hemispherical and annulated, lip annules not marked with longitudinal indentations, sclerotized cephalic framework and a robust spear; A. amplus sp. n. (type-species) and A. nectolineatus sp. n. are described from Portugal and seven new combinations are proposed. Tylenchorhynchus magnicauda (Thorne, 1935) and Tylenchorhynchus graminicola Kirjanova, 1951 are transferred to Amplimerlinius and Merlinius, respectively. Gracilancea gen. n. is proposed for Tylenchus graciloides Micoletzky, 1925 and is placed in Tylodorinae, raised to Tylodoridae grad. n.
