Paramastax rosenbergi (Monkey Grasshopper sp.)


Females in the genus Paramastax can be told apart from males by their drabber appearance and their often swallen abdomen, ended in a scissor-like appendage with which they are presumed to dig into plant stalks to spawn their eggs.
The above two photos show a male.
Paramastax rosenbergi is distinquised from Paramastax poecilosoma and Paramastax duquei by a different tale (only with the males).
The last reddish segment of the tail of P. poecilosoma has a characteristic protrusion (in Dutch: uitsteeksel) (with P. duquei it is smaller) while the last reddish segment of the tail of P. rosenbergi has an indentation (in Dutch: inkeping).
In females, the tails of most species look very similar.
