Zool., 14: 105-114. Descriptions of some Neotropical Euliini and Archipini (Lepidoptera, Tortricidae).- Four new ge- nera (Hyptiharpa n. gen., Hypenolobosa n. gen., Netechma n. gen., Icteralaria n. gen.) and seven new species (Hyptiharpa hypostas n. sp., Hypenolobosa glechoma n. sp.,Atepa colaptes n. sp., Ic- teralaria idiochroma n. sp., 1. ichnobursa n. sp., Clepsis naucinum n. sp. and C. misgurna n. sp.) are described. Key words: Euliini, Archipini, Tortncidae, Lepidoptera, Neotropical.

The holotypes and the majority of the paratypes are deposited in the collection of The present paper contains the descriptions that institution and some paratypes are in the of new taxa of Euliini and Archipini.

Whilst to Euliini belong The number given in the descriptions for 59 described Neotropical genera and several the labial palpus indicates the proportion of further genera are expected (four new genera its total length to the diameter of the eye. are described below), only six genera of Ar- chipini are recorded of that region.
