Predation of pupae of Trichoptera by larvae of Empididae is reported for the first time, and the first descriptions of pupae of Neoplasta are presented. Intact pupal cocoons of Cailloma sp. (Trichoptera: Rhyacophilidae: Hydrobiosinae), collected near Santiago, Chile, each contained a pupa of Neoplasta sp. near brevicornis Collin (Diptera: Empididae: Hemerodromiinae), as well as the cast larval skin and remnants of the pupa of the trichopteran. Pupae of an undetermined species and genus of Hemerodromiinae were found in pupal cocoons of Mortoniella apiculata Flint (Trichoptera: Glossosomatidae) in Ecuador. Similar to pupae of Chelifera and Hemerodromia, but unlike other Empididae, pupae of both species have 1 pair of elangate spiracular gills on the prothorax and on each of the first 7 abdominal segments. Unlike other Hemerodromiinae, the paired integumentary horns on the anterior end are elongate and heavily sclerotized.
