Remarks

• Structure: Adult female body at full growth oblong, sclerotic throughout, divided into 3 parts by marginal constrictions and intersegmental furrows: prosoma (fused head and pro- and mesothorax), metathorax, and abdomen; prosoma as broad as or broader than the metathorax, nearly oblong transversely, broadly tuberculate at each anterolateral corner; metathorax gently lobed laterally; abdomen without distinct intersegmental notches, a little broadening on the base, then gradually narrowing towards the apex of the pygidium. Pygidium slightly roundish along the margin; dorsal surface remarkably reticulate over a broad area, longitudinally striate submarginally; ventral surface roughly and strongly striate longitudinally over the posterior half, with scaly processes on a broad median area of the anterior half. Antennae, on the full-grown body, situated on the frontal margin, separated from each other by a space as wide as the frame of the mouthparts, each bearing a curved seta. (Takagi, 2003) Second-instar male with the median trullae shaped nearly as in the adult female, the second trullae represented by a pair of small, serrate processes, and 2 spiniform pectinae between the median and second trullae; no further lateral trullae present. First instar female and male differing greatly in the size of the legs and also in the size and shape of the trullae situated near the pygidial apex (Takagi, 2003)
• Biology: Females occurring on the lower surface of leaves, burrowing under the tomentum, burrow large, attaining about 5 mm in diameter; Males occurring in the maternal burrow; tests, when fully formed, about 0.8-1.0 mm long and 0.3 mm wide, white, and smooth dorsally (Takagi, 2003). The females of form extraordinarily large burrows, in which males stay, grow, form their tests, and metamorphose into the adult stage. The burrow attains about 3-5mm across, and each may be large enough to accommodate a good number of male tests. However, it seems that the number of male offspring produced by one adult female is generally few. Furthermore, not all the examined burrows harboured male tests. Winged adult males were obtained from a few burrows. (Takagi, 2003).
