The petaltails of the family Petaluridae are among the most ancient of the extant true dragonflies, having fossil members from as early as the Jurassic, over 150 million years ago.
The insect family Macromiidae contains the dragonfly species known as cruisers or skimmers. They tend to fly over bodies of water straight down the middle. They are similar to Aeshnidae in size, but the eyes are green and just barely meet at the top of the head.
The Platycnemididae are a family of damselflies. They are known commonly as white-legged damselflies. There are over 400 species native to the Old World. The family is divided into several subfamilies.
Macromidia is a genus of dragonfly in family Synthemistidae, which is earlier treated as a subfamily of Corduliidae. According to World Odonata List, this genera is best considered incertae sedis. It contains the following species:
The Megapodagrionidae are a family of damselflies, commonly called flatwings for their habit of spreading out the hind wings horizontally when at rest.
The Synlestidae are a family of damselflies commonly known as sylphs or malachites. They occur in South Africa, Australia, and South America.
Isostictidae is a small family of medium-sized to large damselflies restricted to Australia, New Caledonia, and New Guinea. It contains 12 genera and more than 40 species. Members of this family resemble species in the threadtail family (Protoneuridae).
The Synthemistidae are the family of dragonflies commonly known as tigertails, or sometimes called southern emeralds. This family is sometimes treated as a subfamily of Corduliidae. This is an ancient dragonfly family, with some species occurring in Australia and New Guinea. Most species are small in size and have narrow abdomens. Their nymphs are bottom dwellers, and resist droughts by burying themselves very deeply. Synthemistid dragonflies frequently prefer marshy areas, as well as fast-flowing streams. The family Synthemistidae is sometimes called Synthemidae.
The Lestoideidae are a family of damselflies occurring in South-east Asia, New Guinea and Australia. The family comprises two genera and nine species.
Diphlebia is a genus of damselflies in the family Lestoideidae. They are commonly known as rockmasters. These damselflies are very large and thick. The species in this genus are found in Eastern Australia, except for one species that can be found in New Guinea. The males are vividly patterned. They are blue or bluish green and black in colour. Their blue colour also gives them the name azure damselflies. They rest with their wings spread out. Their wings are usually blackish brown or have white markings. These damselflies have several present antenodal crossveins. The two basal crossveins extend across costal and subcostal spaces. The larvae are wide and flat. They have long saccoid gills enabling them to breathe underwater. The inner tooth of their labial palps is elongated. The specific characters of the larva are mid-ventral, distal width, basal width, and length of median lobe.
Philoganga is a genus of damselflies, the only genus in the family Philogangidae.
Diphlebia euphoeoides, sometimes spelled Diphlebia euphaeoides, known as the tropical rockmaster, is an Australian species of broad winged damselfly. It is one of a group known as the azure damselflies. It is found in Queensland (Australia) and Papua New Guinea. It typically occurs near lakes, waterfalls or streams at relatively low altitudes, and is occasionally seen near dry pools.
Diphlebia coerulescens, known as the sapphire rockmaster, is an Australian species of broad winged damselfly. It is one of a group known as the azure damselflies. It is found in Queensland and north-eastern New South Wales in eastern Australia, where it is found in fast-flowing streams and rivers.
Telephlebiidae is a family of dragonflies endemic to eastern and south-western Australia. They are medium-sized to very large dragonflies, generally found around streams.
Cordulephyidae is a small family of dragonflies occurring in Africa and Australia. Members of Cordulephyidae can be small to tiny, black and yellow dragonflies.
Lindeniidae is a family of dragonflies occurring in Australia.
Gomphomacromiidae is a family of dragonflies occurring in Chile and Australia, which until recently was considered to be part of the Corduliidae family.
Lestoidea is a superfamily of damselflies of the order Odonata.
Diphlebia hybridoides is a species of Australian damselfly in the family Lestoideidae, commonly known as a giant rockmaster. It is endemic to north-eastern Queensland, where it inhabits streams in forests.
Diphlebia nymphoides is a species of Australian damselfly in the family Lestoideidae, commonly known as an arrowhead rockmaster. It is endemic to eastern Australia, where it inhabits streams and rivers.
