Allintoshius Chitwood, 1937 is the only genus of the family Ornithostrongylidae (Travassos, 1937) Durette-Desset and Chabaud, 1981 that parasitizes bats. Currently, there are 10 valid species in the genus, of which 3 were described from Brazil. This study describes a new species of Allintoshius and records the first occurrence of a nematode of this genus parasitizing Artibeus lituratus (Olfers). Allintoshius gomesae n. sp. is characterized by having anterior region coiled, cephalic vesicle with cuticular dilation striated transversely, and claviform esophagus. Synlophe in females consists of 16 cuticular ridges at the mid-body. Males have large caudal bursa, and conic and small spicules, and the gubernaculum is absent. Females have uterus didelphic, amphidelphic, tail tip tapered, and ovijector divided into 2 divergent branches, subequal in length. The new species differs from its congeners especially by the shape of the tail tip, vulvar opening, and size of spicules. Allintoshius gomesae is the fourth species of Allintoshius from Brazil and the first report in Ar. lituratus, increasing the number of species recognized of the genus.
Allintoshius Chitwood, 1937 是仅寄生于蝙蝠的 Ornithostrongylidae（Travassos，1937）Durette-Desset 和 Chabaud，1981 科的一个属。目前，该属有 10 个有效种，其中 3 种是在巴西描述的。本研究描述了一种新的 Allintoshius 物种，并记录了该属线虫首次寄生在 Artibeus lituratus（Olfers）中。Allintoshius gomesae n. sp. 的特征是前部卷曲，头泡具横向有条纹的角质扩张，棒状食道。雌虫的体中部有 16 条角质脊。雄虫具有大的尾囊，圆锥形和小的刺，没有精索。雌虫的子宫双胎生，多胎生，尾部逐渐变细，产卵器分为 2 个分叉的分支，长度相等。新种与同属种的区别尤其在于尾部末端、外阴开口和刺的形状和大小。Allintoshius gomesae 是巴西的第四个 Allintoshius 物种，也是 Art. lituratus 中的第一个报告，增加了该属的已识别物种数量。
