Neocordulia setifera is a species of dragonfly in the family Idomacromiidae.[3] It occurs in eastern Brazil and northeastern Argentina, where it inhabits small forest streams and rivers.[1][5]

The species was described by Hagen in Selys in 1871 as Gomphomacromia setifera and was transferred to the genus Neocordulia when Selys established that genus in 1882.[2][6]

Description

[edit]

Neocordulia setifera is a medium-sized dragonfly with a slender body and transparent wings. The thorax is a brilliant dark metallic green, contrasting with the darker abdomen, which bears yellow markings along its sides.[2][5]

The species is distinguished by the prominent tuft of stiff setae on the underside of the eighth abdominal segment of the male, a feature reflected in its scientific name. Selys noted its close relationship with Neocordulia batesi, while recognising consistent differences in the male appendages and abdominal structure.[2][5]

Distribution and habitat

[edit]

Neocordulia setifera occurs in eastern Brazil and northeastern Argentina, where it has been recorded from elevations between 80 and 1,150 m.[1][5]

The larvae develop in small rivers with clear, slow-moving water and sandy substrates. Adults have been observed patrolling along forest trails, dirt roads and streams in secondary forest.[1]

Taxonomic history

[edit]

Neocordulia setifera was described by Hagen in 1871 as Gomphomacromia setifera.[2] In the original description, Hagen characterised it as a "magnificent species" (magnifique espèce), noting particularly the brilliant metallic green thorax and the distinctive male abdominal structures.[2]

When Selys established the genus Neocordulia in 1882, he transferred the species to the new genus, recognising it as one of a distinct group of Neotropical dragonflies.[6] Michael May (1991) subsequently redescribed the species and clarified its diagnostic characters. He also concluded that an earlier record from Ecuador reported by René Martin (1906) was probably based on a misidentified specimen, as no verified records are known from Ecuador or the upper Amazon Basin.[1][5][7]

Etymology

[edit]

The generic name Neocordulia presumably combines the Greek νέος (neos, "new") with the genus name Cordulia, likely reflecting Selys' recognition of the group as a distinct lineage closely related to Cordulia.[6][8]

The species name setifera is presumably derived from the Latin seta ("bristle") and -fera ("bearing"), meaning "bristle-bearing".[8] It likely refers to the prominent tuft of stiff setae on the underside of the eighth abdominal segment of the male, a distinctive feature noted in the original description.[2]
