The Neotropical genus SchacontiaDyar (1914) is reviewed and revised to include eleven species. Schacontia replica Dyar, 1914, syn. n. and Schacontia pfeifferi Amsel, 1956, syn. n. are synonymized with Schacontia chanesalis (Druce, 1899) and eight new species are described: Schacontia umbra,sp. n., Schacontia speciosa,sp. n., Schacontia themis, sp. n., Schacontia rasa, sp. n., Schacontia nyx,sp. n., Schacontia clotho, sp. n., Schacontia lachesis, sp. n., and Schacontia atropos, sp. n. Three species, Schacontia medalba, Schacontia chanesalis, and Schacontia ysticalis, are re-described. An analysis of 64 characters (56 binary, 8 multistate; 5 head, 13 thoracic, 13 abdominal, 25 male genitalic, and 8 female genitalic) scored for all Schacontia and three outgroup species (Eustixia pupula Hübner, 1823, Glaphyria sesquistrialis Hübner, 1823, and Hellula undalis (Fabricius, 1781)) retrieved 8 equally most parsimonious trees (L=102, CI=71, RI=84) of which the strict consensus is: [[[[medalba + umbra] + chanesalis] + speciosa] + [ysticalis + [rasa + themis + [atropos + lachesis + nyx + clotho]]]]. The relevance of male secondary sexual characters to the diagnosis of Schacontia species is discussed.

对新热带属Schacontia Dyar（1914）进行了修订，该属现包含11个物种。Schacontia replica Dyar，1914（新异名）和Schacontia pfeifferi Amsel，1956（新异名）被认定为与Schacontia chanesalis（德鲁斯，1899）同义，同时描述了8个新物种：Schacontia umbra，新物种，Schacontia speciosa，新物种，Schacontia themis，新物种，Schacontia rasa，新物种，Schacontia nyx，新物种，Schacontia clotho，新物种，Schacontia lachesis，新物种，以及Schacontia atropos，新物种。重新描述了三个物种，即Schacontia medalba、Schacontia chanesalis和Schacontia ysticalis。对所有Schacontia物种以及三个外群物种（Eustixia pupula Hübner，1823、Glaphyria sesquistrialis Hübner，1823和Hellula undalis（法布尔，1781））的64个特征（56个二元特征、8个多态特征；5个头特征、13个胸特征、13个腹特征、25个雄性生殖器特征和8个雌性生殖器特征）进行分析，得到8棵同等最简约树（L = 102，CI = 71，RI = 84），其严格合意树为：[[[[medalba + umbra] + chanesalis] + speciosa] + [ysticalis + [rasa + themis + [atropos + lachesis + nyx + clotho]]]]。讨论了雄性第二性征对Schacontia物种诊断的相关性。
