Colombia is one of the megadiverse countries in the world, but paradoxically it is one of the less explored. The recent red
list assessments show the country has the highest number of endangered species in the Neotropical region. Nevertheless,
the sampling effort is low especially in protected areas, which probably can harbor some of the rare species included in
the red list. As a result of recent surveys in six protected areas of Colombia, we report twelve new records and describe
Cora verapax sp. nov., a rare species, collected after more than 300 days of field surveys at the National Natural Park
Tatamá. In addition, we compiled and mapped published Odonata records from 2001 until now for Colombian protected
areas (136 spp.). Among the new records, some species were formerly known as endemics from Panama and Ecuador, and
five species are reported for the first time inside protected areas, showing the importance of surveys in these special territories
and bringing new data for conservation actions, as red list assessment or future management plans.

The Neotropical forest specialist genus Heteragrion counts with 54 species and one subspecies described to date, eight of which have been recorded from Colombia. Here, information on Heteragrion species resulting from ten years of exploration of northwestern Colombia and examination of museum collections, including types and species from Central Amer-ica, is presented. A new species endemic to the Tatamá National Park in the western Andes, Heteragrion tatama sp. nov. is described, as well as the female of Heteragrion aequatoriale Selys, 1886. Heteragrion calendulum Williamson, 1919 was rediscovered, a century after its first collection, which allowed us to compare it with Heteragrion atrolineatum Don-nelly, 1992, and to conclude that the latter species is its junior synonym. We present pictures of female prothoracic inter-sternite, which offer valuable taxonomic information. The variation in coloration patterns for H. aequatoriale and Heteragrion mitratum Williamson, 1919 is discussed, and maps with new distributional data, a taxonomic key, natural history notes and photographs of the Heteragrion species distributed west of the Magdalena valley in Colombia, are also provided.

Epigomphus pechumani Belle, 1970, was described based upon a single male specimen in poor condition, lacking specific
locality in Colombia. Here the male is redescribed and the female is described and illustrated for the first time based on a
total of 18 adults collected in Tatamá National Park, Risaralda Department, and Farallones de Cali National Park, Valle
del Cauca Department, Colombia. A diagnosis, notes on its biology and a distributional map are presented. All material
is deposited in the Entomological collection of Universidad de Antioquia.
