Remarks

• Systematics: The adult female of T. conica would be difficult to confuse with the adult female of any other known species of Tanycelis. The fusion of the hind tibia and tarsus into a broad, sword-like appendage is unique. Both the form of the dorsal setae (robust and slightly curved) and their dense distribution separate adult females from those of other species. Slide-mounted adult female with: many fine, long, curved setae which are most abundant on head and posterior end of abdomen; antennae unsegmented; anterior legs absent; posterior legs very long (Fuller, 1899).
• Structure: Female gall on leaf; opening slit-like on abaxial or adaxial surface, but all galls opening on same surface on any one leaf. Side of gall with opening conical, other side convex, globose. Adult female body outline turbinate, margin incised at intersegmental boundaries. Abdomen tapered, about as long as head + thorax, extending far beyond the femur. A hemispherical gall is formed on the other side of the leaf from a conical apex (Fuller, 1897b). Adult female is very convex and light brown in color (Fuller, 1899).
• General Remarks: Fuller's 1897 original description is very brief: "Upon one side of the leaf arises the conical apex, whilst on the other the gall protrudes as a hemisphere." A more detailed description was found in Fuller (1899) and in 2010, Hardy and Gullan provide a detailed description, photograph of galls and illustration.Most detailed description by Fuller (1899).
