Species
  • Risiophlebia dohrni
  • Risiophlebia guentheri
  • Risiophlebia risi

Species

The genus contains three species:[1][3]

  • Risiophlebia dohrni
  • Risiophlebia guentheri
  • Risiophlebia risi

Risiophlebia guentheri is named after André Günther in honor of his contributions to the study of Odonata.[2]

Range and habitat

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]

Reproduction

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]

Distinguishing species of Risiophlebia

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]
