Material examined.
China: Yunnan: Mengzi city, 22°56'N, 103°32'E, 15.IX.2020, coll. Juan Liu, Dalbergia cochinchinensis ( Fabaceae ), 5 slides (10 adult ♀♀) GoogleMaps .
Diagnosis.
Adult female: body generally large globular to elongate in shape, 1.7-3.87 mm long, 1.16-2.42 mm wide (Fig. 1F, G View Figure 1 ).
Dorsum. Anal tubercle well developed, elongate, 320-1100 µm long, 170-680 µm wide, apparently two-segmented (Figs 1A View Figure 1 , 2B View Figure 2 ) and bearing 6-15 anal ring setae, each 80-90 µm long (Fig. 2A View Figure 2 ); supra anal plate heavily sclerotized, a little longer than broad, with few small setae on each side (Fig. 2B View Figure 2 ); brachia oval, elongate (Figs 1B View Figure 1 , 2E View Figure 2 ), heavily sclerotized; brachial plate nearly circular, broader than long; brachial crater circular and small, 80-160 µm long, 70-130 µm wide, 0.03-0.07 mm2 in center; brachial tube 210-460 µm long, dimples inconspicuous, uncountable due to thick sclerotization (Fig. 2F View Figure 2 ); anterior spiracles widely separated (Figs 1C View Figure 1 , 2G View Figure 2 ), 220-400 µm away from brachial plate, canellar bands below anterior spiracles as a chitinous extension 150-300 µm long (Fig. 1B, C View Figure 1 ); dorsal spine 170-190 µm long, pedicel longer and tubular in shape 80-160 µm long, 70-130 µm wide at widest point (Figs 1D View Figure 1 , 2K View Figure 2 ).
Venter. Antennae very small, conical shaped, probably one segmented, with 4 fleshy and 2 short hair-like setae (Fig. 2J View Figure 2 ); mouthparts with labium length 600-780 µm, width 70-180 µm, post oral lobes each 75-140 µm wide (Fig. 2L View Figure 2 ); legs vestigial; posterior spiracles much smaller with fine pores on each side; perivulvar pores 14-31 in number on each side of anal tubercle (Fig. 2C, D View Figure 2 ); marginal duct clusters convoluted (Figs 1E View Figure 1 , 2H View Figure 2 ), 6 in number, each with 30-36 ducts (Fig. 2I View Figure 2 ); ventral duct clusters with 3 pairs, irregular in shape.
Distribution.
India, Myanmar, Nepal ( Varshney and Sharma 2020), China (Yunnan).
Host plants.
Dalbergia cochinchinensis (specimens collected in this study), Litchi chinensis ( Varshney 1976), and Ficus sp. ( Chen et al. 2011).
