Possible is that the two species can find together because
1. the distribution area of Parosphromenus nagyi is larger than we definitely know
(not only from Cukai to Rompin, maybe in the deep south until to Kota Tinggi)
2. the alleged Parosphromenus alfredi and the nagyis are not from the typical location where we alfredi know from (Sedili), but from another biotope in the area of Kota Tinggi
