Background We revise the genus Metaplagia Coquillett, 1895 and describe five new species from Area de Conservación Guanacaste (ACG) in northwestern Costa Rica. All new species were reared from an ongoing inventory of wild-caught caterpillars spanning a variety of species within the family Sphingidae (Lepidoptera: Sphingidae). Our study provides a concise description of each new species using morphology, life history, molecular data and photographic documentation. In addition to the new species, the authors provide a re-description of the genus and a revised key to the species of Metaplagia. New information The following five new species of Metaplagia are described: Metaplagia leahdennisae Fleming & Wood sp. n., Metaplagia lindarobinsonae Fleming & Wood sp. n., Metaplagia paulinesaribasae Fleming & Wood sp. n., Metaplagia robinsherwoodae Fleming & Wood sp. n. and Metaplagia svetlanakozikae Fleming & Wood sp. n. The following is proposed by Fleming & Wood as new combination of Plagiomima Brauer & Bergenstamm, 1891: Plagiomima latifrons (Reinhard, 1956) comb. n.

Metaplagia Coquillett（双翅目：Tachinidae）的修订，描述了哥斯达黎加西北部瓜纳卡斯特地区的五个新物种

背景 我们修改了 Metaplagia Coquillett 属，1895 年并描述了哥斯达黎加西北部地区 de Conservación Guanacaste (ACG) 的五个新物种。所有新物种都是从持续的野生毛虫清单中饲养的，这些毛虫跨越了鞘翅目（鳞翅目：鞘翅目）的各种物种。我们的研究使用形态学、生活史、分子数据和照片记录对每个新物种进行了简要描述。除了新物种之外，作者还提供了对该属的重新描述和 Metaplagia 物种的修订密钥。新信息描述了以下五个新的化生种：Metaplagia leahdennisae Fleming & Wood sp。n., Metaplagia lindarobinsonae Fleming & Wood sp. n., Metaplagia paulinesaribasae Fleming & Wood sp. n., Metaplagia robinsherwoodae Fleming & Wood sp. n. 和 Metaplagia svetlanakozikae Fleming & Wood sp。n. 以下是 Fleming & Wood 提出的 Plagiomima Brauer & Bergenstamm，1891 年的新组合： Plagiomima latifrons (Reinhard, 1956) 梳子。n.
