在哥斯达黎加，对 5 种侏儒鸟（雀形目：Pipridae）的 170 只个体进行了咀嚼虱（Phthiraptera）检查。已鉴定出六种咀嚼虱。长尾侏儒鸟 (Chiroxiphia Linearis) 的 26% 个体（28 例阳性/109 例检测）中发现了咀嚼虱子或其卵，长尾侏儒鸟是检测数量最多的侏儒鸟。男性和女性之间的感染流行率和强度存在显着差异。女性身上没有发现虱子 (n = 28)，而男性虱子患病率为 35%（24 只阳性/69 只检查）。在老年男性中，感染的患病率和平均强度较高。 2004 年，对来自长尾侏儒鸟的霸王龙属新种——霸王龙托莱多 Sychra, sp. 进行了描述和插图。名词重新描述了 Tyranniphilopterus bruneri 的两性（Carriker，1903）。新寄主记录为入侵蓖麻的长尾侏儒鸟和白领侏儒鸟 (Manacus candei)；白领侏儒鸟 (Corapipo altera) 为 Ricinus pessimalis；长尾侏儒鸟（Myrsidea andyolsoni）。这是长尾侏儒鸟的第一份虱子记录。
One hundred and seventy individuals of five species of manakins (Passeriformes: Pipridae) were examined for chewing lice (Phthiraptera) in Costa Rica. Six species of chewing lice were identified. Chewing lice or their eggs were found on 26% individuals (28 positive/109 examined) of Long-tailed Manakins (Chiroxiphia linearis), the most numerous manakin species examined. There were significant differences in prevalences and intensities of infestation between males and females. No lice were found on females (n = 28) compared to 35% (24 positive/69 examined) prevalence in males. In older males, the higher prevalence and mean intensity of infestation was found. Description and illustrations are given for a new species of the genus Tyranniphilopterus Mey, 2004 from Long-tailed Manakin—Tyranniphilopterus toledo Sychra, sp. n. Both sexes of Tyranniphilopterus bruneri (Carriker, 1903) are redescribed. New host records are Long-tailed Manakin and White-collared Manakin (Manacus candei) for Ricinus invadens; White-ruffed Manakin (Corapipo altera) for Ricinus pessimalis; Long-tailed Manakin for Myrsidea andyolsoni. These are the first louse records from Long-tailed Manakin.
