Yes, this could be a female Clephydroneura sp.; it is definitely an Asilinae genus --- and does look similar to that one. Details of the ovipositor tip, antennae and wing venation would help confirm the genus. Males can be much easier to identify (they usually have expanded wings and elongate genitalia in Clephydroneura); there are also many undescribed robber flies awaiting classification in tropical Asia.
