New province record of Rhinagrion for Thailand and description of the larva of R. mima (Odonata: Zygoptera: Philosinidae).

The Oriental damselfly genus Rhinagrion includes 10 known species, but the larva of only R. philippinum has been described in any detail, while the larva of R. viridatum has been well-illustrated and features summarized. The larvae of the other eight species were unknown. Here, the larva of Rhinagrion mima is described and illustrated by supposition, based upon an F0 larva collected in Phetchabun Province in Thailand. It is compared with the larvae of R. philippinum and R. viridatum . This represents the first record of the genus for Phetchabun Province.
