The Hylodidae genus Megaelosia Miranda-Ribeiro comprises seven frog species that inhabit the Atlantic Rainforest in Southeastern Brazil (Da Silva et al. 2018). Larvae and adults of Hylodidae are commonly associated with lotic streams (Giaretta et al. 1993; Silva-Soares et al. 2015). Tadpoles of all Megaelosia species but Megaelosia bocainensis Giaretta, Bokemann Haddad are formally described, even though many of these descriptions are restricted to few lines and several anatomical details were overlooked (e.g., Megaelosia lutzae; Izecksohn Gouvêa 1985). The tadpole of M. boticariana was briefly described by Giaretta Aguiar (1998) based on a single larva with no measurements or figures. Currently, M. boticariana is only known from its type locality and São Francisco Xavier, both in São Paulo state portion of the Serra da Mantiqueira, Brazil (Muscat et al. 2020). The lack of information, coupled with the rarity of the species, reinforces the importance of taxonomic and natural history data to subside works on other fields. In this context, we present a complete redescription of the external anatomy of the tadpoles of M. boticariana and comment on their natural history.
Hylodidae 属 Megaelosia Miranda-Ribeiro 包含 7 种青蛙，它们栖息在巴西东南部的大西洋雨林中（Da Silva 等人，2018 年）。Hylodidae 的幼虫和成虫通常与急流溪流有关（Giaretta 等人，1993 年；Silva-Soares 等人，2015 年）。除了 Megaelosia bocainensis Giaretta、Bokemann Haddad 之外，所有 Megaelosia 物种的蝌蚪都有正式描述，尽管这些描述中的许多仅限于少数几行，并且忽略了几个解剖细节（例如，Megaelosia lutzae；Izecksohn Gouvêa 1985 年）。Giaretta Aguiar（1998 年）基于一个没有测量值或图像的单一幼虫，简要描述了 M. boticariana 的蝌蚪。目前，M. boticariana 仅在巴西 Serra da Mantiqueira 的圣保罗州部分的其模式产地和 São Francisco Xavier 被发现（Muscat 等人，2020 年）。由于缺乏信息，加上该物种的稀有性，因此，分类学和自然历史数据对于减轻其他领域的工作具有重要意义。在这种情况下，我们对 M. boticariana 的蝌蚪的外部解剖结构进行了完整的重新描述，并对其自然历史进行了评论。
