China : Yunnan : Mengzi city, 22°56'N , 103°32'E , 15.IX.2020 , coll. Juan Liu , Dalbergia cochinchinensis ( Fabaceae ), 5 slides ( 10 adult ♀♀ ) . 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 ). Dorsum . Anal tubercle well developed, elongate, 320-1100 µm long, 170-680 µm wide, apparently two-segmented (Figs 1A , 2B ) and bearing 6-15 anal ring setae, each 80-90 µm long (Fig. 2A ); supra anal plate heavily sclerotized, a little longer than broad, with few small setae on each side (Fig. 2B ); brachia oval, elongate (Figs 1B , 2E ), 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 ); anterior spiracles widely separated (Figs 1C , 2G ), 220-400 µm away from brachial plate, canellar bands below anterior spiracles as a chitinous extension 150-300 µm long (Fig. 1B, C ); 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 , 2K ).

Scale bars: 1000 µm ( A ), 200 µm ( B-G ), 1 cm ( H ). Venter . Antennae very small, conical shaped, probably one segmented, with 4 fleshy and 2 short hair-like setae (Fig. 2J ); mouthparts with labium length 600-780 µm , width 70-180 µm , post oral lobes each 75-140 µm wide (Fig. 2L ); 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 ); marginal duct clusters convoluted (Figs 1E , 2H ), 6 in number, each with 30-36 ducts (Fig. 2I ); ventral duct clusters with 3 pairs, irregular in shape.
