[JF2015] can be readily differentiated from other congenerics by the separated procoxae and the size of the rostrum, which is as wide as the head, and distinctly square in dorsal view. In the males, the dilation of the rostrum is greatly exaggerated, and the lateral margins are flared. The ramus of the spermatheca is basally narrow, forming a stalk that tapers into an apical bulb. The aedeagus is elongate, narrowing towards the apexmore strongly in the region of the ostium.
