Diptera, or true
flies, are extremely diverse but poorly known, especially in the Neotropical
Region. Malaise trap catches from four sites are analyzed and found
to contain mostly Diptera, with nematocerous families numerically dominant.
Taxonomic activity, judged by the number of new species descriptions
over the last 7 years, is extremely low for Neotropical taxa, probably
because of grossly insufficient resources available to the few available
researchers.
