Notes: One new genus and species are described based upon the materials collected from Anhui Province, China. All type specimens are deposited in the Anhui University of Technology, Ma'anshan. Mammilla, gen. nov. Type species: Mammilla jinzhaiensis, sp. nov. The new genus is close to Megacanthaspis Takagi, 1961 and Poliaspoides MacGillivray, 1921, but can be distinguished by lacking a perivulvar pore and having 4 microtubular duct groups in venter. It also differs from the other genus in this family by presence of the marginal mammilla spine. Mammilla jinzhaiensis, sp. nov. (Figs 1-16) Scales of females elongate 1.6-2.0 mm long, 0.6-0.7 mm wide. White in color, one exuviae apical, elliptical, pale yellow-brown.

Dorsal surface: The dorsal ducts of one type, two-barred, arranged in rows in abdominal segments, irregular in the cephalo-thoracic region. Simple pores and minute setae sparse. Ventral surface: Antennae tubercular, with two long setaes and one short seta. Ventral ducts of two types: small ducts and minute ducts. Small ducts distributed in submargin, microducts numerous, forming 4 groups around anterior and posterior spiracular, and with irregular distribution on venter. Anterion and posterior the spiracular of near with quinquelocular pores 4-5, the dens of spiracular with quinquelocular pores 10-12. Apex of abdomen: The pygidial end subcircular, with a marked "V"-like notch, each side of the notch with 1 pointed spine, 2 spines with round apex. Anal ring little and circular. With 2 minute setae located on the dorsum of the notch centered. Vulvar on the ventral surface of notch, without perivulvar pores. Holotype: female, Jinzhai County, Anhui Province, China, 18-?-2005, WU Shi-jun; Paratypes: 8 females, same data as the holotype
