: During a long-term study on biodiversity of bats in the Yungas and Entre Ríos provinces, 1,304 specimens of bats included in the families Noctilionidae, Phyllostomidae, Vespertilionidae, and Molossidae were collected and checked for filarioids. Litomosoides molossi Esslinger, 1973 was recovered from the thoracic and abdominal cavities of Molossus molossus (prevalence [P] = 6.4%); Litomosoides chandleri Esslinger, 1973 from Artibeus planirostris (P = 6.9%), Sturnira oporaphilum (P = 66.6%), Sturnira erythromos (P = 23.8%), Sturnira lilium (P = 7.2%), and Eumops perotis (P = 50%); and Litomosoides saltensis n. sp. was collected from Eptesicus furinalis (P = 1.7%). In this paper, we emend the description of L. molossi; describe a new species, Litomosoides saltensis n. sp., on the basis of 1 female specimen; and report for the first time L. molossi and L. chandleri parasitizing Argentinean bats, expanding the host and locality records. Litomosoides molossi exhibits a slender buccal capsule, with an anterior segment transparent, and the posterior chitinous portion displays 2 thickenings in the first third; possesses 1 dorsal prominent cephalic papilla and 4 labial papillae distributed around the mouth; cuticle with lateral punctuations all along the hypodermic chords in both sexes; and male with area rugosa and tail without cloacal papillae. In L. chandleri, the lateral punctuations are distributed on the posterior extremity of the body in both sexes. Litomosoides saltensis n. sp. displays a thick buccal capsule with a posterior segment well cuticularized, possessing 2 thickenings in the anterior half; 4 labial and 2 ventral cephalic papillae; a globular vulva located anterior to the esophagus-intestine junction; cuticle with lateral punctuations in the posterior extremity of the body; and tail with salient phasmids. We also provide a taxonomic key for the identification of the Litomosoides sp. of bat dwelling. Long-term studies and large sample sizes are needed to detect the presence of Litomosoides sp. in bats, in contrast to the findings in cricetid rodents, which seem to be more frequently collected.
在一项关于永加斯省和恩特雷里奥斯省蝙蝠生物多样性的长期研究中，采集了夜蛾科、叶口蝠科、蝙蝠科和犬吻蝠科的1304只蝙蝠标本，并检查是否有丝状线虫。1973年的莫氏丝虫（Litomosoides molossi Esslinger）从皱唇犬吻蝠（Molossus molossus）的胸腔和腹腔中检出（感染率[P]=6.4%）；1973年的钱氏丝虫（Litomosoides chandleri Esslinger）从扁嘴果蝠（Artibeus planirostris）（P=6.9%）、嗜果蝠（Sturnira oporaphilum）（P=66.6%）、红毛果蝠（Sturnira erythromos）（P=23.8%）、黄肩果蝠（Sturnira lilium）（P=7.2%）和秘鲁犬吻蝠（Eumops perotis）（P=50%）中检出；盐河丝虫新种（Litomosoides saltensis n. sp.）从棕蝠（Eptesicus furinalis）中采集到（P=1.7%）。在本文中，我们修订了莫氏丝虫的描述；基于1只雌性标本描述了一个新物种，盐河丝虫新种；并首次报道了莫氏丝虫和钱氏丝虫寄生于阿根廷蝙蝠，扩大了宿主和分布记录。莫氏丝虫的口囊细长，前段透明，后段几丁质部分在前三分之一处有2处增厚；有1个背侧突出的头部乳突和4个围绕口部分布的唇乳突；两性的角质层沿皮下索都有侧向小孔；雄性有皱纹区，尾部无泄殖腔乳头。在钱氏丝虫中，两性的侧向小孔分布在身体后端。盐河丝虫新种的口囊厚，后段角质化良好，前半段有2处增厚；有4个唇乳突和2个腹侧头部乳突；球形阴门位于食管-肠道交界处前方；角质层在身体后端有侧向小孔；尾部有明显的尾感器。我们还提供了一个分类检索表，用于鉴定栖息于蝙蝠的丝虫属物种。与仓鼠科啮齿动物的发现相比，需要长期研究和大样本量来检测蝙蝠中丝虫属物种的存在，仓鼠科啮齿动物似乎更常被采集到。
