Two new species were detected while sorting and identifying specimens of
Adult crane flies were collected at ultraviolet light and with an insect net, and preserved in 96% ethanol. Specimens were studied with a Nikon SMZ800 (Nikon, Japan) and an Olympus SZ61 (Olympus, Japan) stereomicroscopes. Images were taken with a Canon EOS 80D (Canon, Japan) mounted on an Olympus SZX10 (Olympus, Japan) stereomicroscope and with a KUY NICE (KUY, China) mounted on an Olympus SZ61 stereomicroscope. The genitalia were studied after boiling in a 10% NaOH solution for 5–10 minutes.
