Systematics of Apatelodidae Neumoegen & Dyar, 1894 (Lepidoptera: Bombycoidea) based on molecular and morphological data.

Apatelodidae is a family of New World bombycoids distributed mainly in the Neotropical region, with 14 genera, 222 valid species and 8 subspecies. These moths are medium-sized with a wingspan ranging from 2 to 8 cm, generally greyish, straw-yellow or reddish-brown, with darker spots and lines on the dorsal side of the wings. We combine adult morphology and molecular data to test, under a probabilistic framework, the monophyly of apatelodid genera and the placement of Tamphana (Bombycidae). We sampled the type species of 12 of the 14 valid genera of Apatelodidae, including the type species of synonymised genera. We sampled ~75% of the species from all valid genera in the family and outgroups from Bombycidae, Brahmaeidae, Eupterotidae and Phiditiidae, totalling 195 terminals. Examination of the specimens resulted in a matrix of 138 morphological characters (116 from male; 22 from female) from the head (7 from male; 1 from female), thorax (37 from male; 4 from female), abdomen (5 from male) and genitalia (66 from male; 17 from female). For the molecular analyses, we used four genes: DDC (647 bp) for 14% of terminals; CAD (2486 bp) for 23% of terminals, Wgl (409 bp) for 38% of terminals and COI (658 bp) for 75% of terminals. Species of Tamphana were recovered in Apatelodidae as two independent clades. The genera Arotros , Crastolliana , Drepatelodes , Pantelodes , and Prothysana were recovered as monophyletic. The remaining apatelodid genera were polyphyletic. We propose a new genus-level classification: Tamphana is transferred to Apatelodidae; 16 new genera are proposed: Aymara gen. nov. , Campesina gen. nov. , Caribas gen. nov. , Cecile gen. nov. , Kaweskar gen. nov. , Lempira gen. nov. , Misak gen. nov. , Mocambo gen. nov. , Nhanderu gen. nov. , Peabiru gen. nov. , Raoni gen. nov. , Tapuia gen. nov. , Tibira gen. nov. , Tupac gen. nov. , Tuyvae gen. nov. and Zapata gen. nov. Two new species are described: Mocambo lauracensis sp. nov. , and Nhanderu takua sp. nov. We revalidate the genus Hygrochroa stat. rev. and three species: Carnotena perlineata stat. rev., Tupac bombycina stat. rev., comb. nov. and Zanola vivax stat. rev. Overall, we propose 82 new generic combinations, synonymise 16 species, and restore the status of 3 species: Apatelodes floramia stat. rest. , Carnotena rectilinea comb. nov. , stat. rest. and Ephoria nubilosa stat. rest. Additionally, we summarise data on the natural history and distribution of each Apatelodidae species. ZooBank: We sampled ~75% of Apatelodidae species from all valid genera and combined morphological and molecular data to test monophyly of its genera. Our findings demonstrate that most Apatelodidae genera, as currently understood, are not monophyletic and revealed that groups of species with similar characters may constitute valid genera. We propose a new genus-level classification for Apatelodidae and include data on its natural history and geographical distribution. (Image credit: Guilherme Fischer.) [ABSTRACT FROM AUTHOR]
