New taxa, including three new genera show uniqueness of Neotropical Nepticulidae (Lepidoptera)

After finding distinct clades in a molecular phylogeny for Nepticulidae that could not be placed in any known genera and discovering clear apomorphic characters that define these clades, as well as a number of Neotropical species that could be placed in known genera but were undescribed, three new genera and nine new species are here described from the Neotropics: Stigmella gallicola van Nieukerken & Nishida sp. n. reared from galls on Hampea appendiculata (Malvaceae) in Costa Rica, representing the first example of a gall making Stigmella; S. schinivora van Nieukerken sp. n. reared from leafmines on Schinus terebinthifolia (Anacardiaceae) in Argentina, Misiones; S. costaricensis van Nieukerken & Nishida sp. n. and S. intronia van Nieukerken & Nishida sp. n. each from a single specimen collected the same night in Costa Rica, Parque Nacional Chirripó; S. molinensis van Nieukerken & Snyers sp. n. reared from leafmines on Salix humboldtiana, Peru, Lima, the first Neotropical species of the Stigmella salicis group sensu stricto; Ozadelpha van Nieukerken gen. n. with type species O. conostegiae van Nieukerken & Nishida sp. n., reared from leafmines on Conostegia oerstediana (Melastomataceae) from Costa Rica; Neotrifurcula van Nieukerken gen. n. with type species N. gielisorum van Nieukerken sp. n. from Chile; Hesperolyra van Nieukerken gen. n.. with type species Fomoria diskusi Puplesis & Robinson, 2000; Hesperolyra saopaulensis van Nieukerken sp. n., reared from an unidentified Myrtaceae, Sao Paulo, Brasil; and Acalyptris janzeni van Nieukerken & Nishida sp. n. from Costa Rica, Guanacaste. Five new combinations are made: Ozadelpha ovata (Puplesis & Robinson, 2000) comb. n. and Ozadelpha guajavae (Puplesis & Diškus, 2002) comb. n., Hesperolyra diskusi (Puplesis & Robinson, 2000) comb. n., Hesperolyra molybditis (Zeller, 1877) comb. n. and Hesperolyra repanda (Puplesis & Diškus, 2002) comb. n. Three specimens are briefly described, but left unnamed: Ozadelpha specimen EvN4680, Neotrifurcula specimen EvN4504 and Neotrifurcula specimen RH2.
