Resumen:
Monte is a warm shrub desert of Argentina, having particular biogeographical
interest because it lies between the Neotropical and Antarctic regions. A preliminary
list of some insect families shows a high proportion of endemic genera
and species, supporting the hypothesis that it constitutes a natural area with its
own biodiversity. The distribution of some insect species shows great concordance
with the area occupied by the Monte Desert, indicating its limits. However
the complete series of records are not enough to define the boundaries exactly.
The distributional patterns of several endemic species suggest that within
Monte there are five natural areas: Northern, Central, Uspallata-Calingasta,
Southern, and PenmH nsula de ValdeH s. The limits of the Northern and Uspallata-
Calingasta areas are due to physiographical features (mountains) whereas the
remaining areas are delimited by climatic barriers. An analysis based on
phylogenetic information shows that these areas of endemism reflect different
values with respect to their biodiversity. The Northern area has the
highest values of importance and has no protected areas.
