Not sure why you think this is a parinsignifera. It has the typical striped version back pattern of signifera rather than the lyrate pattern found in both species, but the only pattern for parinsignifera. Unless you can provide a recording of the call, the only other helpful clue is a photo of its belly. Marbled black and white in signifera and granular grey in parinsignifera. Always worth including if the situation allows for it.
