Guiana Shield dragonflies Odonata aims
Main aim of these pages is to compose a list of dragonfly species
which occur on the Guiana Shield. I am most grateful to Dennis Paulson and Jürg DeMarmels for helping me to
create this
list.
With this list it is more easy to
check which species are likely to occur in this part of the the five
countries and its possible to make regional identification keys.
Secondly it is a way of survey areas in need of protection or in need of
study; as DeMarmels (1999) did for Venezuela and Paulson (2004) did for
the Neotropics. As we know more about the possible endemics in the
countries (which numbers are given in Paulson, 2004) we can more easily
track them in other countries.
The Guiana Shield is defined as the three Guiana's the eastern part
of Venezuela, the northern part of Brazil (while Columbia east of the
Andes could be included but is not in this study). The most species rich site
on the Guiana is the Cerro de la Neblina (00°49'50"N,
66°09'40"W) in the very south of Venezuela, next to the Brazilian
border. Here, during a few months of 1984, 152 species were collected in
an area of approximately 625 km2 (De Marmels, 1989).
The list which follows is primarily based on the list published by
Dennis Paulson (2005) South American Odonata List of the Odonata of
South America, By Country. See legend
for further notes.
