The Colombian Amazon is one of the most biodiverse and unexplored regions in the world. Inventories and deeper research are needed for most of its biota, including for dragonflies. This work reports the results of a trip to the Amazon region in order to collect Odonata. It includes revision of CBUCES, CEUA and ICN entomological collections and a li...

Tropical mountains display limited variation in monthly temperatures, but high spatial climatic variability. It is assumed this stability promotes ecological and physiological adaptations to local temperatures, which may preclude dispersal up or downslope. Determining how environmental, taxonomic and morphological factors affect thermal limits is f...

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 t...

Basal metabolic rates (BMRs) increase with temperature and body mass. Environmental temperatures rapidly change in tropical mountains due to elevation (macro scale) and vegetation structure (micro scale). Thus, tropical mountains are good settings for testing the effects of temperature on BMRs. We measured the BMRs at four temperature ranges on six...

The larvae of Epigomphus rufus Bota-Sierra & Novelo-Gutiérrez, 2020, and E. brillantina Bota-Sierra & Novelo-Gutiérrez, 2020 (by supposition) are described, figured and compared with other described larvae of the genus. The larva of E. rufus is characterized by 3 rd antennomere spindle-shaped, 2.12x as long as widest part; ligula with a ventral row...

The páramos are high mountain ecosystems in the tropical regions of the New World, and they are particularly threatened by climate change. The Belmira páramo complex in Colombia is home to Mesamphiagrion gaudiimontanum, an endemic and endangered damselfly species. This study presents the first demographic assessment of M. gaudii­montanum using the...

Colombian odonatological history was scarce until two decades ago. Here, we present an updated, thoroughly vetted, and refined checklist of taxonomic and geographical records of Colombian odonates, built upon the previous publication in 2011. To achieve this, we conducted an extensive literature review, and curated the most representative biologica...

Aim Insects are one of the least studied taxa, with most species lacking basic ecological and biogeographical information. This problem is particularly acute in the tropics, where low sampling effort hampers accurate estimates of species richness at scale and potentially confounds efforts to identify the drivers of biogeographical gradients. Here,...

Magnolia unicarmensis is described as a new species of mountain Colombian Magnoliaceae. M. unicarmensis can be distinguished from the other members of subsection Dugandiodendron by a combination of characters, including smaller leaf size (3.20-6.73 × 1.91-3.93 cm); leaf shape obovate, base cuneate, woolly abaxial pubescent only in the midvein exten...

In this study, we have comprehensively presented taxonomic information on all 62 known species of Heteragrion Selys, 1862, which includes illustrations, photographs, diagnostic characters, and a key to males. Our analysis is based on the examination of over 900 specimens from 19 different collections worldwide, encompassing the type material for at...

Diaphlebia richteri is shown to be a junior synonym of Zonophora nobilis. The confusion started by a generic misplacement due to the failure to observe the subalar carina spine which is present in Zonophora but not in Diaphlebia. Therefore, Z. nobilis is officially recorded for the first time in Colombia; we present a distribution map with the know...

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...

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. We also provide a distribution map and a taxo-nomic key for...

We report ten new records of Odonata, including the true distribution of Acanthagrion yungarum Ris, 1918 in Colombia.

The damselflies Hetaerininae, a subfamily of Calopterygidae, comprise four genera distributed from North to South America: Hetaerina, Mnesarete, Ormenophlebia and Bryoplathanon. While several studies have focused on the intriguing behavioral and morphological modifications within Hetaerina, little of the evolutionary history of the group is well un...

The larva of Miocora aurea (Ris, 1918) was found in first and second order forested streams at the Tatamá National Park in the Colombian Western Andes. Here it is described and figured the final larval stadium. It differs from the larva of M. chirripa (Calvert, 1917) by a combination of features such as antennal pedicel (0.25x longer than 3rd anten...

Rarely have studies assessed Odonata diversity for the entire Nearctic realm by including Canada, the United States, and Mexico. For the first time, we explored Odonata diversity in this region according to a definition of natural community assemblages and generated species distribution models (SDMs). Species occurrence data were assembled by revie...

The large genus Heteragrion has a wide distribution in the Neotropics from southern Mexico to northern Argentina, occurring from sea level to 1800 m.a.s.l. In Colombia, so far ten species and two subspecies of the genus Heteragrion have been found; here we raise this number to 14, with three new records for the country (H. angustipenne Selys, 1886,...

Here we describe Andaeschna occidentalis sp. nov., first species of the genus recorded in the Western Andes, specifically from the Tatamá National Park in Colombia. Males of this species can be differentiated from the other...

Eight species of Ischnura are known from Colombia; five of them are Andean en-demics, four from the Eastern Cordillera and one from the Central Cordillera. Here, we describe a new species thus far known only from the Central Cordillera, Ischnura solitaria sp. nov. (Holotype ♂ from Belmira, Antioquia, Colombia, 6.711305°N, 75.628503°W, 2 615 m a.s.l...

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 speci...

During 2.5 months of intensive fieldwork in Colombia (departments of Cauca, Nariño, and Putumayo, South America) from January to March 2017, we visited 13 localities and collected 291 specimens of 68 species of Odonata, including 17 new records for the country. We report range expansions for several species assessed as data deficient or under some...

The Neotropical forest specialist genus Heteragrion counts with 54 species and one subspecies described to date, eight of which have been recorded from Colombia.

The genus Mesamphiagrion Kennedy, 1920, occurs in the Pantepui region and northern Andes in South America and is most speciose in Colombia where the genus is less known. In this work, we record 10 species of Mesamphiagrion from Colombia, including four new species (Mesamphiagrion gaudiimontanum Bota-Sierra sp. nov., M nataliae Bota-Sierra sp. nov.,...

As with most taxa present in Colombia, the study of dragonflies is still in its exploratory phase. This paper reports the results of a trip to the Amazon region in order to collect dragonflies. Seven new records for the country were found, including the rediscovery of Proneura prolongata Selys and an undescribed species in the genus Calvertagrion S...
