Remarks

• Structure: Adult female body robust, deeply constricted between the metathorax and abd I. Head and thorax fused to form a conspicuous mass, which is transversely oblong, broader than the abdomen, and swollen laterally to form a low tubercle on each side; abd I and II forming together a round lobe laterally; pygidium swollen marginally on its base (abd III), rather rapidly narrowing posteriorly, and rounded along a road apical margin. At maturity, the fused head and thorax become sclerotic, with some more heavily sclerotized patches on the dorsal surface; dorsal surface of the pygidium sclerotic, longitudinally striate, with sci erotized patches laterobasally; ventral surface with a pair of sclerotized bands arising from the bases of the median trullae and extending to the lateral ends of the vulva. Antennae situated between the frontal margin and the mouthparts, separated from each other by a space nearly as wide as the frame of the mouth-parts, each with a single seta. (Takagi, 2003) First-instar female and male differing greatly in the length of the legs. (Takagi, 2003)
• Biology: Female occurring on the lower surfave of leaves, burrowing under the velevety cover of trichomes; burrow large, about 5 mm in diameter at maximum, and externally recognizable by an obscure slight swelling on the velevety cover; test rudimentary and very thin (Takagi, 2003). Male tests occurring within the maternal burrow, oblong, thin and white (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).
