Two new species of the genus Hoplopeza Bezzi (Diptera, Hybotidae, Ocydromiinae) from the high Andean forests of Colombia.

Two new Andean species of Hoplopeza Bezzi are described and illustrated: Hoplopeza colombiana sp. nov. and Hoplopeza rafaeli sp. nov. These species are the first record from the Andean ecosystem of Colombia. In addition, the genus is diagnosed, the first description of the female terminalia, as well as a key and distribution map of the Andean species of the genus are presented.

Four new Neotropical species of Eudicrana Loew (Diptera, Mycetophilidae, Sciophilinae) from the Colombian high Andean ecosystems, with comments on the genus.

Four new species of the sciophiline genus Eudicrana Loew are described for the Eastern and Central Andes of Colombia-Eudicrana silvaandina sp. nov., E. chingaza sp. nov., E. maculata sp. nov. and E. merizaldei. These are the first species of Eudicrana described from the extreme northern range of the Andes. The altitudinal distribution of these species in the paramos and high Andean forest ecosystems is restricted to 1750-3660 m a.s.l. and some other information on the environment is briefly discussed. A key for the Colombian species of Eudicrana is provided and a discussion is elaborated on the position of these species within the genus.

Revision of the Neotropical Neuratelia Rondani (Diptera, Mycetophilidae, Sciophilinae): two new species, a new combination, and a new synonym.

We describe two new Neotropical species of Neuratelia Rondani from the high Central Andes of Colombia, N.altoandina sp. nov. and N.colombiana sp. nov. The holotype of Eudicranaelegans Lane actually is a species of Neuratelia and a new combination is proposed. Our examination of the holotype of Neurateliasapaici Lane from southeastern Brazil shows this species to be a synonym of N.elegans (Lane), which is formally proposed here. Neurateliasapaici is redescribed. The position of these three species within the genus is discussed. A key for the Neotropical species of Neuratelia is provided.
