Elattoneura, the African threadtails, is a genus of damselflies in the family Platycnemididae. They were formerly placed in genus Prodasineura, but form a distinct clade. The adults are smallish and delicately built damselflies, and their males have very wide heads. The adults are typically found in sheltered locations beside or over running water, though a few prefer calmer water with much detritus. There appears to be two groups with differing habitat preferences. Those with pruinose faces and mostly blue eyes occupy watercourses in open terrain, while those with black or brightly coloured faces are found along forested streams.
Elattoneura leucostigma is a species of damselfly in the family Platycnemididae known commonly as the smoky-winged threadtail. It is endemic to Sri Lanka, where it is known from only one location. It has not been found in any recent surveys. It is known from streams in dense forest habitat, and the area has undergone habitat destruction and pollution of local waterways.
Gomphidia pearsoni is a species of dragonfly in the family Gomphidae. It is endemic to Sri Lanka. Its natural habitats are subtropical or tropical moist lowland forests and rivers. It is threatened by habitat loss.
Heliogomphus ceylonicus is a species of dragonfly in the family Gomphidae. It is endemic to Sri Lanka. Its natural habitats are subtropical or tropical moist lowland forests and rivers. It is threatened by habitat loss.
Heliogomphus lyratus is a species of dragonfly in the family Gomphidae. It is endemic to Sri Lanka. Its natural habitats are subtropical or tropical moist lowland forests and rivers. It is threatened by habitat loss.
Heliogomphus nietneri is a species of dragonfly in the family Gomphidae. It is endemic to Sri Lanka. Its natural habitats are subtropical or tropical moist lowland forests and rivers. It is threatened by habitat loss.
Macrogomphus lankanensis is a species of dragonfly in the family Gomphidae. It is endemic to Sri Lanka. Its natural habitats are rivers and irrigated land. It is threatened by habitat loss.
Microgomphus wijaya is a species of dragonfly in the family Gomphidae. It is endemic to Sri Lanka. Its natural habitats are subtropical or tropical moist lowland forests and rivers. It is threatened by habitat loss.
Sinhalestes orientalis, the emerald Sri Lanka spreadwing, is a species of damselfly in the family Lestidae. It is the only species in the genus Sinhalestes. The species was thought to be extinct since none have been found since it was first scientifically described in 1862. However, in 2012 this species was re-discovered by a young odonatologist Amila Sumanapala from the Peak Wilderness Sanctuary, Sri Lanka.
Tetrathemis yerburii is a species of dragonfly in the family Libellulidae. It is endemic to Sri Lanka. Its natural habitats are subtropical or tropical moist lowland forests and rivers. It is threatened by habitat loss.
Crocidura hikmiya is a species of shrew described from the rainforests of Sri Lanka, based on both morphological and molecular data. Its closest sister species is the Sri Lankan long-tailed shrew, another Sri Lankan crocidurine shrew restricted to the high-elevation habitats of the Central Highlands. C. hikmiya has a shorter tail than the Sri Lankan long-tailed shrew. Most of the other characteristics that distinguish the two species are osteological natured .
Elattoneura oculata is a species of damselfly in the family Platycnemididae known commonly as the two-spotted threadtail. It is endemic to Sri Lanka, where it is a rare species known from a few locations in the southern and central parts of the island. It lives along streams in primary rainforest habitat, an ecosystem threatened by habitat destruction and degradation.
Sri Lanka exhibits a remarkable biological diversity and is considered to be the richest country in Asia in terms of species concentration.
