The following information was extracted from
the document "A Seven Year Plan for an Inventory of the Diptera of Costa
Rica" (September 1998) by D.M Wood and Manuel Zumbado and up dated with
recomendations of the Diptera Taxonomic working group follow up workshop
held on June 2000.
For its size, Costa Rica must have one of the
most diverse faunas of any country in the world. Unfortunately, however,
the taxonomy of most of the families of Costa Rican flies is not well
developed, especially among families in which the flies themselves are
very small. We estimate that there are between 20,000 and 30,000 species
of flies in Costa Rica, but scarcely 900 of these have been recorded
in the literature. A recent survey of the tachinid literature revealed
that fewer than 5% of the expected species of Tachinidae have been mentioned
from Costa Rica, and the same is true for most other families, of which
there are almost 90 so far recorded in Costa Rica.Tabanidae, Mosquitoes
(Culicidae) may be an exception, however, because the group is well
known in the Neotropical Region, but even for mosquitoes it is not possible
at the present time to state precisely how many species are found in
Costa Rica.
On May 29 1998, the Diptera Taxonomic Working
Group (TWIG) met to develop sampling and curatorial protocols to maximize
the data to be obtained by the Diptera TWIG.
In June 11-15, 2000 some of the Diptera TWIG
members met in Monterverde to evaluate the process of collecting, mounting
and identification of specimens. Likewise, the strategy for the Manual
of the Diptera of Costa Rica was defined.
