摘要
Many hemiepiphytic plants secrete a thick layer of mucilage to limit desiccation and protect against fungal pathogens. With its stable moisture and protected location, this mucilage constitutes a potentially attractive microhabitat for small animals; however, until now, no animal species have been recorded from it. Larvae of a psychodid fly were collected from the mucilage of a hemiepiphytic Araceae in Braulio Carillo National Park, Costa Rica. Rearing of the larvae yielded specimens of pupae and one adult male described here as Mucomyia emersa Kvifte and Curler gen. nov. sp. nov. An additional species from Costa Rica, Mucomyia browni Kvifte sp. nov., is described based on adult males from the Zurqui de Moravia forest reserve. Mucomyia belongs to tribe Psychodini, which comprises both habitat generalists and specialists. The new species are morphologically similar to those in Philosepedon s. str. and Eurygarka, both of which are known to develop in snail carrion. It is premature to speculate about whether or not species in the new genus are restricted to hemi-epiphyte mucilage.
