It appears to be associated with dead branches of Casuarina trees. The tube has weakly convex margins ( Fig. 8 ) but without prominent setae and the area of the anal ring is not sharply constricted. The head and thorax are similar in structure to rugicauda , although usually with rather less erosion of various sclerites. The mesopresternum is sometimes transverse and slender, but frequently eroded. Similarly, the median posterior margin of the pelta is usually slightly eroded, but in one large male it is fully eroded to a pair of small irregular sclerites. Specimens studied .
