Tillyard, 1913[1]

The genus is endemic to north-east Queensland, Australia, where its species inhabit rainforest streams.[3]

Species of Lestoidea are medium-sized to large damselflies, dark brown to black in colour, with dull orange, greenish or bluish markings.[3][4] Most species have a pale spot at the base of each antenna, although this is absent in Lestoidea lewisiana.[3]

Taxonomic history

edit

In 1913, Tillyard described the genus Lestoidea based on Lestoidea conjuncta, regarding it as intermediate between the damselfly groups then recognised as Lestes and Protoneura.[1]

For many years Lestoidea was considered to contain only a single species.[5] In 1967, Watson described a second species, Lestoidea barbarae, from north-east Queensland.[5]

In 1996, Günther Theischinger revised the genus and recognised four distinct species, describing Lestoidea brevicauda and Lestoidea lewisiana.[6]

Description

edit

Species of Lestoidea inhabit rainforest streams in north-east Queensland, with some species restricted to particular mountain ranges or upland regions.[3][6]

The genus is distinguished by the elongated pterostigma and by reduced wing venation near the base of the wing.[3][1] Larvae are relatively flat-bodied and possess sac-like caudal gills.[3]

Species

edit

The genus Lestoidea has four species:[7]

Etymology

edit

The genus name Lestoidea is derived from Lestes and the Greek suffix -οειδής (oeidēs, "resembling" or "having the form of"), indicating resemblance to that genus.[1][8]
