The Corduliidae, also knowns as the emeralds, emerald dragonflies or green-eyed skimmers, is a family of dragonflies. These dragonflies are usually black or dark brown with areas of metallic green or yellow, and most of them have large, emerald-green eyes. The larvae are black, hairy-looking, and usually semiaquatic. This family include species called "baskettails", "emeralds", "sundragons", "shadowdragons", and "boghaunters". They are not uncommon and are found nearly worldwide, but some individual species are quite rare. Hine's emerald dragonfly, for example, is an endangered species in the United States.
Somatochlora, or the striped emeralds, is a genus of dragonflies in the family Corduliidae with 42 described species found across the Northern Hemisphere.
The Bulgarian emerald, Corduliochlora borisi, is a species of dragonfly in the family Corduliidae, and the only species in the genus Corduliochlora. It is found in Bulgaria, Greece, and Turkey.

Anania shanxiensis is a moth in the subfamily Pyraustinae of the family Crambidae. It was described by Zhaofu Yang and Jean-François Landry in 2019 as Anania sinensis, which turned out to be a junior secondary homonym of a previously described taxon, Anania lancealis sinensis(Munroe & Mutuura, 1968). The replacement name for A. sinensisYang & Landry, 2019 is Anania shanxiensisYang & Landry, 2019.
Somatochlora shennong is a species of dragonfly in the family Corduliidae. It was described in 2014 based on specimens from Hubei, China, and is also known from Guangxi. It occurs at narrow ditches with dense emergent vegetation. It is related to two other east Asian species: Somatochlora dido and Somatochlora taiwana.
Somatochlora daviesi is a species of dragonfly in the family Corduliidae. It was first described in 1977 based on specimens from Meghalaya, India, and is also known from Nepal and Bhutan. It resembles the east Asian S. dido in its small size and lack of yellow markings on most of the abdomen. Like other species in the genus, S. davisi is predominantly dark metallic brown to green. The formerly recognised Somatochlora nepalensis is now considered to be a synonym of S. daviesi.
Somatochlora dido is a species of dragonfly in the family Corduliidae. It is known from southeastern China and northern Vietnam, but populations in Vietnam may alternatively represent a separate, undescribed, species. S. dido has sometimes been treated as synonymous with S. taiwana from Taiwan, but more recent publications have treated them as separate species. S. shennong is also closely related.
Somatochlora uchidai is a species of dragonfly in the family Corduliidae. It is native to Japan, China and Russia. It was described in 1909 by German entomologist Friedrich Förster based on specimens from Japan; the name uchidai refers to the Japanese odonate researcher Uchidas from whom Förster received the specimens.
Somatochlora taiwana is a species of dragonfly in the family Corduliidae. It is endemic to Taiwan, and is the only member of the genus Somatochlora found there. It is a metallic green to black dragonfly with yellow spots, and measures about 35 mm long. It is closely related to S. shennong and S. dido, and is sometimes treated as conspecific with the latter species.
Somatochlora lingyinensis is a species of dragonfly in the family Corduliidae. It was described in 1979 based on a specimen from Lingyin in Zhejiang, China. No other specimens are known.
Somatochlora exuberata is a species of dragonfly in the family Corduliidae. It is found in eastern Russia, northern China, Korea, and Hokkaido, Japan.
Somatochlora graeseri is a species of dragonfly in the family Corduliidae. It is found in Asia, where it occurs in Japan, Korea, northern China, and Russia.
