A new species of capillariid nematode, Freitascapillaria laticauda n. sp. (Capillariidae), is described from the intestine of the blue ridge sculpin, Cottus caeruleomentum (Cottidae, Scorpaeniformes) from the Blue Lick Run, Maryland, United States. It differs from its congeners mainly in the body length (male 3.1-5.4 mm, female 7.0-11.1 mm), the length of the male esophagus (1.5-2.9 mm) and spicule (42-45 microm), and the size of eggs (60-66 x 27-33 microm). Previous records of Freitascapillaria spp. were from characid, poeciliid, and cyprinid fishes in Brazil, Neotropical Mexico, and China, respectively, so that F. laticauda n. sp. is the first species of this genus reported from Nearctic North America and from a scorpaeniform fish.
一种新的毛细科线虫，宽尾弗氏毛细线虫（Freitascapillaria laticauda n. sp.）（毛细科），是从美国马里兰州蓝舔溪的蓝岭杜父鱼（Cottus caeruleomentum）（杜父鱼科，鲉形目）的肠道中描述的。它与其同属物种的主要区别在于体长（雄性3.1 - 5.4毫米，雌性7.0 - 11.1毫米）、雄性食管长度（1.5 - 2.9毫米）和交合刺（42 - 45微米）以及虫卵大小（60 - 66×27 - 33微米）。此前弗氏毛细线虫属的记录分别来自巴西的脂鲤科、花鳉科鱼类，新热带区墨西哥的鱼类以及中国的鲤科鱼类，因此宽尾弗氏毛细线虫是该属在新北区北美洲以及鲉形目鱼类中报道的首个物种。
