Abstract

Thubunaea acostai sp. nov. is described and illustrated here, based on specimens found in the digestive tract of Liolaemus gracielae in the province of San Juan, Argentina. The new species differs from all other species assigned to Thubunaea by the number of caudal papillae. Thubunaea acostai sp. nov. has 30-31 papillae (12 pedunculated and 18-19 sessile), differing from other Neotropical species such as Thubunaea eleodori with 26 papillae (12 pedunculated and 14 sessile) and Thubunaea parkeri with 20 papillae, all pedunculated. The new species represents the third species for the Neotropics and the second described for Argentina.

摘要

本文描述并图示了一种新的扁虫物种——Thubunaea acostai sp. nov.，该物种发现于阿根廷圣胡安省的 Liolaemus gracielae 的消化道中。新物种与所有其他归入 Thubunaea 的物种的区别在于尾肛乳头的数量。Thubunaea acostai sp. nov. 有 30-31 个肛乳头（12 个有柄和 18-19 个无柄），与其他新热带物种如 Thubunaea eleodori（26 个肛乳头，12 个有柄和 14 个无柄）和 Thubunaea parkeri（所有肛乳头均有柄）不同。新物种代表了新热带地区的第三个物种，也是阿根廷的第二个描述的物种。
