Twenty-five bats were trapped in Yutaje (Amazonas, Venezuela) and examined for Litomosoides (Filarioidea: Onchocercidae). Of the nine recovered bat species, only Pteronotus parnelli was infected; it is a cave-dwelling species belonging to a family, Mormoopidae, which has not previously been included in the host range of the genus. The new species, L. yutajensis n. sp., has two median cephalic bosses covered with rugosities and differs from the 15 recognized species and subspecies from bats in several characters. Alike L. molossi Esslinger, 1973, L. chandleri Esslinger, 1973 and L. chitwoodi Bain, Guerrero, Rodriguez 2003, the new species has cuticular lateral bosses on the body. Eight of 10 P. parnelli were microfilaraemic, but only three had adult worms, showing that microfilariae survive longer than adults, which could lengthen the period of transmission. No infective larvae were detected in the following macronyssid mites: 58 Ornithonyssus bacoti, Ornithonyssinae, experimentally fed on microfilaraemic bats and dissected 15 days later, and a few Radfordiella sp., Macronyssinae, recovered from P. parnelli.
在委内瑞拉亚马逊州的尤塔耶捕获了25只蝙蝠，并对其进行了丝状虫属（丝虫超科：盘尾丝虫科）检查。在9种捕获的蝙蝠物种中，只有帕氏叶鼻蝠受到感染；它是一种栖息在洞穴中的物种，属于叶鼻蝠科，该科以前未被列入该属的宿主范围。新物种尤塔耶丝状虫，有两个覆盖着皱纹的头部中间隆起，在几个特征上与15种已知的蝙蝠丝状虫属物种和亚种不同。与1973年的埃斯林格莫氏丝状虫、1973年的埃斯林格钱氏丝状虫和2003年的贝恩、格雷罗、罗德里格斯奇氏丝状虫一样，新物种在身体上有表皮侧隆起。10只帕氏叶鼻蝠中有8只血液中有微丝蚴，但只有3只体内有成虫，这表明微丝蚴比成虫存活时间更长，这可能会延长传播期。在以下巨刺螨中未检测到感染性幼虫：58只食蟹猴巨刺螨，巨刺螨亚科，以血液中有微丝蚴的蝙蝠为食，并在15天后解剖，以及从帕氏叶鼻蝠身上采集到的几只拉德福德螨属，巨刺螨亚科。
