It is endemic to coastal north-east Queensland, where it inhabits rainforest streams.[5]
Lestoidea conjuncta is a medium-sized to large damselfly with dark coloration and dull orange to greenish markings.[6]
Taxonomic history
editIn 1913, Tillyard described Lestoidea conjuncta as the first species of the new genus Lestoidea.[2]
Tillyard regarded the species as unusual because it appeared to combine characteristics of several damselfly groups then recognised as distinct.[2]
For many years Lestoidea conjuncta was considered to be the only species in the genus.[7] In 1967, Watson described a second species, Lestoidea barbarae, from north-east Queensland, noting differences in wing venation and male appendages.[7]
In 1996, Günther Theischinger revised the genus and showed that some specimens previously identified as Lestoidea conjuncta represented distinct species.[8] As part of this revision he described two additional species, Lestoidea brevicauda and Lestoidea lewisiana.[8]
Description
editLestoidea conjuncta is a medium-sized to large damselfly, dark brown to black in colour, with dull orange to greenish markings.[6]
A pale spot is present at the base of each antenna.[4] Males have distinctive appendages at the tip of the abdomen, with the upper pair bent sharply downward and ending in a blunt tip.[4][8]
Females can be identified by the shape of the rear margin of the section behind the head, which is narrow and only slightly upturned at the sides.[4][8]
Distribution and habitat
editEtymology
editThe genus name Lestoidea is derived from Lestes and the Greek suffix -οειδής (oeidēs, "resembling" or "having the form of"), indicating resemblance to that genus.[2][9]
The species name conjuncta is derived from the Latin coniungo ("to join together"), referring to its apparent links to two distinct archaic groups within the family Agrionidae.[2][9]
