Psocoptera from the Calakmul Biosphere Reserve, and neighboring areas (Campeche, Mexico)

A survey of the Psocoptera of the Calakmul Biosphere Reserve, Campeche, Mexico, was conducted in 1997 and early 1998. The collecting effort was 260 man-hours, excluding the operation of light and Malaise traps. A total of 1675 specimens was taken, representing 96 species, in 48 genera and 23 families. The proportional to Diversity Index for this collection was 22.12. Fifteen species constituted 66.7% of the total number of specimens, and 40 species constituted 3.9% of the same total. Only 18 of the 96 species present in the area are widely distributed locally, whereas 72 of the 96 species in the area showed restricted local distribution. The level of endemism is high (19.79% of the total number of species).
