Phylogenetic systematics of Schacontia Dyar with descriptions of eight new species (Lepidoptera, Crambidae)

Abstract. The Neotropical genus Schacontia Dyar (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 umbr...

Sumario:Abstract. The Neotropical genus Schacontia Dyar (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.
