Cauda tongue-shaped, about 0.1200.140 mm long. (Measurements see in Table 1.). Apterous viviparous female: In life yellow or yellowish green In colour. In mounted specimens body oval (Fig. 1), about 1.767 to 1.984 mm in length. Compound eyes about 6.5 times longer than triommatldion, consisting of about 67-84 ommatidla. Frons sinuated, median frontal tubercle a little higher than lateral frontal tubercles. Antennae usually 6-Jointed, about 0.45-0.61 times as long as body, pale in colour; processus terminális gradually slightly paler towards apex. Length of antenna! joint from third to sixth as 0.215-0.300, 0.140-0.190, 0.110-0.120, 0.100 for the basal part and 0.235-0.265 for the unguis, respectively. Processus terminális 2.4-2.7 times as long as base of Joint VI, and 0.78-1.20 times the length of Joint m. Third antennái joint without secondary rhinaria and with 8-10 hairs. Tip of rostrum generally reaching to top of middle coxae; ultimate rostral joint about 0.110 mm long, 1.0-1.1 times as long as second Joint of hind tarsi. Head and thorax sclerotized; pale in colour. Compound eyes, legs light brownish, siphunculi, cauda and genital plate paler. Transverse rows of indistinct imbrication on abdominal tergites anterior to siphunculi. Metanotum fused with abdominal tergites I to VI forming a pale patch.Dorsum hardly pigmented, pale In colour (in life shiny), tergites VII and VIII free; dorsal shield quite smooth. Marginal tubercles absent on mesothorax; mesosternal processes absent. Marginal tubercles absent on metathorax and abdominal tergites, and spinal tubercles absent on abdominal tergites VII and VIII. Tergite VIII with 8-10 hairs, mostly with filamentary apices, arranged in a row on posterior margin of this segment; longest hairs 0.030-0.040 mm long, 1.0-1.3 times as long as basal diameter of antennái joint III. Longest hairs on antennái joint III 0.010 mm long,

Siphunculi conical or tapering, smooth, distinctly flanged and usually with a preapical striate circumcision, 0.160-0.165 mm long, about 0.08-0.09 times the body length, about 1.5-1.7 times the length of second joint of hind tarsi. Cauda tongueshaped or sub-pentagonal with a slight basal constriction, and about 0.100-0.105 mm long, about 0.8 times as wide at base as its length, bearing 6 hairs. Legs bearing numerous fine hairs. Hind tarsal joint II about 0.100-0.110 mm long. First tarsal joint with 3, 3, 2 hairs. (Measurements see in Table 1.) Alate viviparous female: In mounted specimens head and thorax brown, abdomen with a brown well-developed dorsal patch extending from abdominal tergites IV to VII (Fig. 2). Antennae dark brown, about 0.6-0.9 times the length of body; joint III with about 19-30 secondary rhinaria of various sizes; Joint IV with 6-11 rhinaria. Compound eyes brown consisting of about 66-84 ommatidla. Legs brown, excepting pale brownish bases of tibiae. Siphunculi and cauda pale brownish. Wings with normal venation. Other characters about as in apterae vivlparae. (Measurements see in Table 1.) Apterous oviparous female: Like apterous viviparous female in shape, but differs in lengths and size (Fig. 3). Compound eyes 4 times longer than triommatldion, consisting of about 32-38 ommatidla. Processus terminális 1.0-1.5 times as long as length of joint III. Antennái joint III with about 1-2 hairs and without secondary rhinaria. Siphunculi shorter than in apterae vivlparae pale brown and about 0.070-0.085 mm long. Cauda thicker and with one or two more hairs, about 0.050-0.065 mm long. Subgenital plate with many hairs over the whole surface. Hind tibiae with basal half considerably swollen, darker and with a great number of small pseudosensoria. (Measurements see in Table 1.) Alate male: In mounted specimens body more slender and shorter than in alate viviparous (Fig. 4), about 1.023-1.178 mm long. Head and thorax wholly dark sclerotic. Antennae usually 6jolnted, dark brown and about 0.9 times as long as body length; antennái joint III with about 28-39 secondary rhinaria; joint IV with about 18-21; joint V with 8-10 secondary rhinaria.
