- General Remarks: Description and characters by Takagi (2003).
- Systematics: This genus is so peculiar in the characters of the adult female that it is not easy to find a relationship to other forms (Takagi, 2003).
- Structure: The body is tripartite, being distinctly constricted between the meso- and metathorax and also between the metathorax and the abdomen. The apex of pygidium is produced to form a narrow obdeltate area, set with elongate, elaborately serrate median trullae on the entire lateral margins, thus forming a prominent, conical, serriferous process. The lateral trullae are well represented in three pairs and unilobed. There are well-developed glanduliferous spiniform processes on the pygidial margin, and some of them are expanded and dentate on the lateral base. The pygidium is devoid of macro ducts except for a few long filiform ducts arising marginally or submarginally. There are, however, small ducts of the two-barred type in the prepygidial region. The second-instar male possesses macroducts of the two-barred type on both the pygidium and the prepygidial region. In this latter instar, the macroducts are not
diminished in size, and those on the dorsal surface of the pygidium are thickly rimmed around their orifices. (Takagi, 2003)
