The genus contains three species: [1] [3]
Risiophlebia guentheri is named after André Günther in honor of his contributions to the study of Odonata. [2]
Deforestation and the establishment of new plantations is the biggest threat to Risiophlebia. [4] The Nee Soon freshwater swamp, located in the Central Catchment Nature Reserve, is the only site in Singapore where R. dohrni can be found. [5] R. dohrni is extremely rare, making them hard to find and study. [6] R. dohrni has been documented in the Central Kalimantan province of Indonesia. [7] R. dohrni has also been documented at the island of Belitung in Indonesia. [8] R. guentheri was first discovered at the Central Plateau of the Annamese Mountains, [3] and was named after André Günther as a homage to his contributions to the study of Odonata. [2]
Risiophlebia dohrni reproduce in freshwater and peat swamp forests. [9] Larvae are found in freshwater where they prey on other aquatic organisms, such as tadpoles and small fish. [10]
Risiophlebia risi possess a forewing triangle that resembles the shape of a wide rhombus. [11] In R. risi, the hindwing triangle is located at the arculus and is not recessed. [11] The forewing triangle of R. dohrni has a normal shape and the hindwing triangle is recessed. [11]
