Abstract

Prodasineura yulan was observed in a small peaty-water stream in the Iban Dayak customary land of the Sungai Utik, West Kalimantan, Indonesia. It had previously only been known from the holotype male from Maludam National Park in Sarawak. The observation indicates a wider distribution, but with no other sites discovered as yet, the species should still be considered endangered. A checklist of Odonata that have been observed in the Sungai Utik area is included.
