Black fungus gnats of Central America. Part I. (Diptera, Sciaridae).

Abstract

The material of this first part on Sciaridae of Central America was collected in various localities in Costa Rica and Honduras. 51 species of 21 genera were identified. 40 species, 4 genera and 3 subgenera are described for the first time. The following genus group taxa are treated (number of species given in brackets): Acuatella gen. nov. [1], Bradysia [8], Chaetosciara [1], Corynoptera [2], Cratyna (Cratyna s. str.) [3], Cratyna (Spathobtella) [1], Epidapus (Epidapus) [1], Epidapus (Pseudoaptanogyna) [1], Epidapus (Clandestina subgen nov.) [3], Eugnoriste [1], Hyperlasion [2], Leptosciarella (Leptosciarella) [1], Leptosciarella (Protosciarella subgen. nov.) [3], Leucosciara gen. nov. [2], Odontosciara (Odontosciara) [1], Odontosciara (Obscura subgen. nov.) [1], Phytosciara (Dolichosciara) [1], Pseudolycoriella [3], Pseudosciara [2], Pterothrix gen. nov. [2], Rhynchosciara [1], Scatopsciara (Scatopsciara s. str.) [1], Schwenckfeldina [2], Sciara [1], Trichosciara gen. nov. [1], Zygomma [5]. Most of the taxa are of South American affiliations and quite different from the Holarctic sciarid fauna. The Central American representatives of the cosmopolitan genera Sciara, Chaetosciara, Epidapus, Phytosciara, Pseudolycoriella, Schwenckfeldina and (for the most part) Bradysia are similar to species of the old World. The Central American species of the cosmopolitan subgenus Cratyna s. str. show more similarities to species from tropical areas of the Australian and Oriental region. Holarctic and/or Nearctic genera, like Leptociarella (Leptociarella s. str.), Corynoptera, Scatopsciara and Eugnoriste are represented in Central America only by few species. Bradysia, Cratyna, Pseudolycoriella, Pseudosciara, Zygomma, and Leptosciarella (subgenus Protosciarella) are diverse, common, and consequently typical Central American elements.
