An update on the distribution of threatened odonate species from the Greater Antilles

The Antilles harbour several island endemic odonate species, including some palaeoendemics, within a relatively small and anthropized area. Such attributes give this archipelago a special significance for the conservation of Odonata in the Neotropics. However, despite the importance of these islands, inadequately surveyed regions persist, mainly in the Greater Antilles, and there is not enough…

Generic revision of Argiolestidae (Odonata), with four new genera

The subfamily Argiolestinae is raised to family level to include all zygopteran genera in which the gills of the larvae are flat and held in a horizontal plane. A diagnosis of the family is given and characters for both adults and larvae are presented. The family is divided into two subfamilies based on characters in…

Description of the larva of Trineuragrion percostale Ris (Odonata: Megapodagrionidae) with a key to the larvae of New Caledonian genera of Megapodagrionidae

The larva of Trineuragrion percostale is described and illustrated based on an exuvia collected with the teneral female. Four more exuviae sampled without imagines are added for comparison and discussion of morphological variations. This is the first time the larva has been associated with the correct species, although the larval description was given earlier. Lieftinck

Seasonal ecology of Algerian Lestidae (Odonata)

When comparing the phenology of species within the family Lestidae in Numidia, northeastern Algeria, we found that: (1) four of five species—Lestes barbarus, L. numidicus, L. viridis, and Sympecma fusca—feature a prolonged pre-reproductive period approaching five (Lestes spp.) or eight months (S. fusca); (2) adults of L. numidicus, and probably of S. fusca, move to…

The life history of a temperate zone dragonfly living at the edge of its range with comments on the colonization of high latitudes by Neotropical genera of Zygoptera (Odonata)

Of the many Zygopteran genera that occur in the Neotropics, only five (Hetaerina, Archilestes, Lestes, Argia, and Ischnura) are represented north of 40°N in North America, and only three of these (Hetaerina, Archilestes, and Argia) probably had a tropical origin. In the two genera of Lestidae (Archilestes and Lestes) the life history of temperate-zone populations…

Odonata of Guangdong, Hong Kong and Macau, South China, part 1: Zygoptera

Extensive surveys for odonates were completed in protected areas throughout Guangdong Province, south China during the period 1997-2005. Previously unreported data from these surveys is presented here and, together with published data, is used to catalogue the zygopteran fauna of Guangdong. Checklists are provided for the Zygoptera of Guangdong, Macau and Hong Kong. Sinosticta debra…

Reciprocal predation involving Odonata, Asilidae and Saltatoria

A singular observation of an adult Tettigonia viridissima (Tettigoniidae) that captured a female Eutolmus rufibarbis (Asilidae) sucking a male Lestes sponsa (Lestidae) is reported. The reciprocal predation of Odonata, Asilidae, and Saltatoria (Ensifera, Caelifera) hitherto recorded in Europe is compiled and augmented by unpublished data on asilids as predators of odonates. Heavy predation by robber-flies…

Heteragrion makiritare sp. nov with descriptions of hitherto unknown females and larvae of other species from Venezuela (Odonata: Megapodagrionidae, Lestidae)

Heteragrion makiritare sp. nov. is described from two males from the Pantepui region – holotype: Venezuela, Amazonas State, Marahuaka, Sima (3°43′N, 65°31′W), 1,140 m a.s.l., MIZA, no. 17250. It belongs in the species group whose paraprocts are absent in the male sex. The identity of H. macilentum is elucidated by examining its lectotype and a…
