Gomphomacromia signata sp. n. is described and illustrated based on a single male collected in Napo Province, Ecuador.
Forests have been widely recognized as key habitats for odonate (dragonflies and damselflies) biodiversity, but the importance of forests for holding odonate biodiversity remains understudied in tropical mountains, one of the most diverse ecosystems on the planet. Here we describe the odonate assemblage composition along the elevation gradient in the Tatamá Mountains (Colombian Cordillera Occidental).
The family Philogeniidae was recently proposed as a monophyletic clade grouping the genera Philogenia and Archaeopodagrion. Here, two new species found during recent expeditions to the Western Colombian Andes are described, Archaeopodagrion fernandoi sp. nov. and Philogenia martae sp. nov. Also, Philogenia zeteki is recorded for the first time in Colombia. Natural history notes, a…
Aeshna (Hesperaeschna) condor sp. nov. is described and illustrated from four males and six exuviae. The adult color pattern does not resemble that of any other Venezuelan species, but structurally the new species comes closest to A. (H.) punctata and A. (H.) joannisi. This latter is here recorded for the first time from Venezuela, and…
The traditional method of classifying the twenty-one species within the South American genus Polythore has been relying on wing color patterns and male genital ligula shape. However, recent molecular research has shown that wing color patterns can vary significantly within some species, making it an insufficient means of species diagnosis by itself in some cases.
A new damselfly species, Philogenia realpei sp. nov., is described here from 5 ♂♂, 2 ♀♀ collected at Cauca and Putumayo departments in southern Colombia. This species is included in the P. helena group and can be differentiated from other species by the unique morphology of its paraprocts.
This study aims to preliminary assess the taxonomic diversity of dragonflies and damselflies from San José del Guaviare, Guaviare Department, Colombia. A total of 47 species were collected at five localities in different freshwater ecosystems during a field trip.
Oreiallagma oreas (Ris, 1918) is a recently rediscovered Colombian Andean endemic species, for which the information available is very scarce. It was originally described from a single male. Since 2008, O. oreas has been recorded in new localities but its life history remained unknown. Here we describe and diagnose the species female for the first…
To date 57 species of Telebasis have been described. Most are Neotropical species, only three extending North of Mexico. From Peru 17 species were known. Most are found in the Amazonian lowlands; two are known from higher elevations in the Andes. From Brazil 26 species were known. In this article another Neotropical species is described,…
We studied a population of Polythore procera along a stream in the Colombian eastern Andean foothills. Mark and recapture samples were made during January to April 2006, covering both dry and wet seasons. We determined population size, daily survival probability, and longevity during the entire period and compared them with precipitation data. Age and sex…
