Tetraneura (Tetraneurella) sorini Hille Ris Lambers, 1970 View in CoL

Fundatrix first instar nymph: Body elliptical, becoming thinner posteriorly, 0.76−1.19 (on average 0.93) mm long, 0.31−0.53 (0.42) mm wide on abdominal segment II, 0.38−0.45 (0.41) times as wide as long ( Figure 4C View FIGURE 4 ). Antennae short, 5-segmented, smooth and not imbricated, 0.18−0.20 (0.18) mm long, 0.54−0.59 (0.57) times the length of hind femorotorochanter ( Figure 4F View FIGURE 4 ). Fore femorotrochanter 0.15−0.25 (0.20) mm long, fore tibia 0.11−0.20 (0.15) mm long, hind femorotrochanter 0.22−0.43 (0.33) mm long, hind tibia 0.19−0.38 (0.30) mm long ( Figure 5F View FIGURE 5 ). Rostrum reaching hind coxae; ultimate rostral segment rather slender, 0.10−0.17 (0.14) mm long, 0.28−0.55 (0.41) times as long as the length of hind femorotrochanter.

Emigrant adult: Body elongated oval, 1.95−2.13 (2.08) mm long, without wax gland plates ( Figure 6C View FIGURE 6 ). Antennae 6-segmented, 0.63−0.70 (0.66) mm long, 0.30−0.35 (0.32) times as long as body, 0.97−1.07 (1.02) times as long as hind tibia ( Figure 6F, I View FIGURE 6 ). Antennal segment III 0.19−0.23 (0.21) mm long, 1.15−1.28 (1.19) times as long as segment V. Antennal segment IV 0.076 −0.091 (0.085) mm long, segment V 0.17−0.18 (0.17) mm long. Secondary rhinaria present on segments III−V, covering usually 1/3−2/3 circumference of the segments from the ventral side. Ultimate rostral segment 0.095 −0.110 (0.103) mm long, 0.52−0.70 (0.62) times as long as the second segment of hind tarsus ( Fig 6L View FIGURE 6 ). Hind femorotrochanter 0.45−0.53 (0.494) mm long. Second segment of hind tarsus 0.15−0.18 (0.17) mm long ( Figure 6O View FIGURE 6 ). First tarsal chaetotaxy 3:2:2. Cornicles absent.

Sexupara adult: Body 1.72−2.94 (2.26) mm long ( Figure 7C View FIGURE 7 ). Wax gland plates present on the whole body except the posterior segments of abdomen. Antennae 6-segmented, 0.74−0.90 (0.84) mm long, 0.29−0.44 (0.38) times as long as body, 0.96−0.89 (0.94) times as long as the length of hind tibia ( Figure 7F, I View FIGURE 7 ). Antennal segment III 0.24−0.32 (0.30) mm long, 1.1−1.2 (1.2) times as long as segment V. Antennal segment IV 0.070 −0.095 (0.079) mm long, segment V 0.23−0.27 (0.25) mm long. Secondary rhinaria present on segments III−V, covering usually 1/2−3/4 circumference of the segments from the ventral side. Ultimate rostral segment 0.12−0.17 (0.15) mm long, 0.73−0.84 (0.80) times as long as the second segment of hind tarsus ( Figure 8C View FIGURE 8 ). Hind femorotrochanter 0.57−0.70 (0.64) mm long, hind tibia 0.78−1.01 (0.89) mm long. Second segment of hind tarsus 0.17−0.20 (0.18) mm long ( Figure 8F View FIGURE 8 ). First tarsal chaetotaxy 3:2:2. Wax gland plates on marginal abdomen with two types of facets, larger ones of which are present in the center of plate, and small ones present peripherally ( Figure 8I, L View FIGURE 8 ). Cornicles 0.057 −0.080 (0.070) mm in diameter ( Figure 8O View FIGURE 8 ).
