description: Rhopalus maculatus
1 Abdominal terga 2–7 without thorn-shaped robust processes each side, terga 5–7 with long, flattened, medially swollen, apically pointed setae on dark pigmented tubercles laterally (Figs. 1, 19, 34, 37); setae on dorsal abdominal surface arise from almost flat alveoles. Six distinct dark brown flattened setae on head between eyes. Wing pads not developed (Figs. 1, 4, 34). Lengths of 1–4 antennomeres: average 0.14 (min. 0.12– max. 0.17), 0.26 (0.19–0.31), 0.27 (0.20–0.32), 0.39 (0.32–0.44), average body length =1.40 (range, 0.99–1.86). Body weakly elongated, general body color green................ 1 st instar
- Abdominal terga 2–7 sublaterally with distinct thorn-shaped robust process each side, process composed from anterior dark part bearing two distinct setae and posterior pale part, terga 5–7 without long, flattened, medially swollen, apically pointed setae (Figs. 2, 3, 20–23, 35, 38, 39); setae on dorsal abdominal surface arise from distinct protuberant alveoles. Flattened setae on head not developed. Wing pads not developed (2 nd instar) or developed. Average body length 1.67 or greater. Body oval or ovoid, general body color pink with red spots around bases of setae.............................................. 2
2 Mesothorax and metathorax slightly convex dorsally. Mesonotal wing pads not developed, posterior margin of mesonotum arcuate (Figs. 2, 5). Metanotum subrectangular. Lengths of 1–4 antennomeres: 0.19 (0.17–0.20), 0.37 (0.34–0.41), 0.35 (0.31– 0.39), 0.51 (0.48–0.54), average body length = 2.15 (range, 1.67–2.60)..................................... 2 nd instar
- Mesothorax and metathorax flattened. Mesonotal wing pads developed, posterolateral angles of mesonotum elongated at least into short, rounded wing pads (Figs. 3, 6–8, 35). Metanotum narrowly transverse or medially only as narrow strip. Average body length 2.15 or greater.............................................................................. 3
3 Transverse furrow on pronotum not developed, posterior margin of pronotum weakly arcuate. Beginning of scutellum not evident, posterior margin of mesonotum between wing pads almost straight medially. Mesonotal wing pads short, rounded, reaching abdominal tergum 1 (Figs. 3, 6, 35). Metanotal wing pads not developed. Lengths of 1–4 antennomeres: 0.26 (0.24–0.31), 0.52 (0.46–0.56), 0.47 (0.43–0.51), 0.69 (0.65–0.75), average body length = 2.83 (range, 2.11–3.23).............. 3 rd instar
- Transverse furrow on pronotum shallow to distinctly developed, posterior margin of pronotum weakly to distinctly sinuate. Beginning of scutellum evident, posterior margin of mesonotum between wing pads convex, rounded or pointed. Mesonotal wing pads elongate, reaching beyond abdominal tergum 1 (Figs. 7, 8). Metanotal wing pads developed, short, almost completely overlapped by mesonotal wing pads (Figs. 7, 8). Average body length 3.38 or greater.......................... 4
4 Beginning of scutellum evident on posterior margin of mesonotum, rounded, short, not covering metanotum, not detached from wing pad by mesonotal groove each side. Mesonotal wing pads reaching abdominal tergum 2 (Fig. 7). Metanotum medially only as narrow strip. Developing external genitalia not present. Lengths of 1–4 antennomeres: 0.36 (0.34–0.43), 0.74 (0.66–0.82), 0.64 (0.56–0.70), 0.96 (0.88–1.09), average body length = 4.10 (range, 3.38–4.95).................. 4 th instar
- Beginning of scutellum on posterior margin of mesonotum, triangular, large, covering metanotum, detached from wing pad by distinct mesonotal groove each side. Mesonotal wing pads long, reaching at least abdominal tergum 3 (Fig. 8). Metanotum medially covered by beginning of scutellum. Developing external genitalia present (male’s abdominal sternum 9 compact, female’s abdominal sternum 9 divided by longitudinal groove medially). Lengths of 1–4 antennomeres: 0.45 (0.40–0.50), 0.95 (0.86–1.06), 0.86 (0.79–0.97), 1.29 (1.09–1.45), average body length = 5.88 (range, 4.90–6.86).................. 5 th instar
