Species Discoveries & Notable Contributions

1. Caiusa pooae 

2. Striatosedulia pooae

1. I discovered a new species of Calliphorid fly in Thailand (Caiusa pooae) that preys upon treefrog eggs. This species was described by Prof. Kunt Rognes in 2015, who named the fly after me. Zootaza, 3952 (1): 001-080.   PDF | URL  

2. A grasshopper in Thailand (Striatosedulia pooae) was named after me by a student I mentored at the Sakaerat Environmental Research Station. This species was described by Tan et al in 2017. Far Eastern Entomologist, 333:1-9.   PDF
