Differential diagnosis. Mandible with four teeth (x D. austerus, D. comatus, D. cyrtus, D. intermedius, D. osellai, D. oxalidis, D. palumbarius, D. tesselatus and Hypera -species (subgenera Eririnomorphus, Dapalinus, Boreohypera and Hypera s.str.)) (Fig. 60). Prn1–10 bacilliform (x D. comatus, D. crinitus, D. cyrtus, D. oxalidis, D. palumbarius, H. dauci and H. vidua). Prs and pds1–4 on thoracic segments bacilliform (x D. comatus, D. cyrtus, D. oxalidis, D. palumbarius, D. tesselatus, H. dauci and H. vidua). Pds2 on dorsum of meso- and metathorax not the shortest seta (x D. palumbarius and D. tesselatus). Pds2 and pds3 on meso- and metathorax not close each other (x D. intermedius, D. oxalidis and D. tesselatus). Dpls on meso- and metathorax bacilliform (x D. comatus, D. crinitus, D. cyrtus, D. osellai, D. oxalidis, D. palumbarius, D. tesselatus, H. dauci, H. lunata and H. vidua) (all Fig. 61). Prn, prs and pds1–4 on thoracic segments and prs, pds1–5 on abdominal segments I–VIII short (x D. cyrtus, D. intermedius, D. oxalidis, H. dauci and H. vidua) (Figs 61– 62). Prs and pds1–5 on abdominal segments I–VIII bacilliform (x D. comatus, D. cyrtus, D. oxalidis, D. tesselatus, H. dauci and H. vidua). Prodorsum of abdominal segments I–VII only with one seta (prs) (x D. osellai). Pds 1–5 in line on abdominal segments I–VII, not pds2 positioned anteriad to pds3 and pds4 anteriad to pds5 (x D. cyrtus, D. intermedius, D. oxalidis, D. tesselatus, H. dauci and H. vidua). Pds4 on dorsum of abdominal segments I–VI not the longest seta (x D. palumbarius) (all Fig. 62). Ds3 1.3 x longer than ds1–2, 4 (x D. austerus, D. comatus, D. crinitus, D. cyrtus, D. intermedius, D. osellai, D. oxalidis, D. palumbarius, D. tesselatus and H. dauci) (Fig. 63).
Description of mature larva.
COLORATION. Head pale brown, posterior and lateral margins of epicranium dark. Dorsal side of body green with white median stripe.
HEAD. Head width 1.25 mm (1.23–1.28 mm), head length 1.18 mm (1.15–1.20 mm) (Table. 1). Frontal sutures distinct, slender, anteriorly nearly indistinct. Anterior margin of clypeus distinctly concave (Fig. 57) with pigmentation. Labrum pale brown; anterior margin with slender median excision, posterior margin with short and wide median projection (Fig. 57). Mandibles with four sharp teeth apically (Fig. 60).
THORAX. Spiracle with oval airtubes oriented dorsad.
ABDOMEN. Spiracles with oval airtubes oriented posterio-dorsad.
CHAETOTAXY. Head. Setae hairform. Des2 the shortest, about 0.5 x des4; des4 about 0.6 x des1, des3 and des5, approximately of same length (Fig. 57). Both les long, approximately of same length. Both ves short. Fs1 and fs3 the shortest, about 0.7 x fs4; fs4 about 0.5 x fs5 (Fig. 57). Both cls very short, lrms1–3 short (Fig. 57). Both mds very short (Fig. 60). Sts1–2 long; sts3 short, about 0.5 x sts1–2 (Fig. 58). Dms1–6 stout (Fig. 59), vms1–5 minute. Mxps very short. Plbs1–2 long; plbs3 very short, about 0.25 x plbs1–2; prms long as plbs1; both lig minute (Fig. 58).
Thorax (Fig. 61). Bases of setae strongly pigmented, setae pigmented. Setae short, bacilliform or hairform (vpls, pda, msts). Prothorax: prn1–8 short; prn9–10 shorter than previous setae (prn1–8), about 0.7 x. Vpls2 about 0.3 x vpls1. Pedal lobe with three (three to five) setae (pda); pda1–2 long, pda2 about 0.75 x pda1; remaining one (one to three) seta minute. Msts minute. Meso- and metathorax: prs and pds1–4 very short, approximately of same length. Both dls very short, both ss very short. Dpls and vpls 2 x longer than previous setae. Pedal lobe with three (three to five) setae (pda); pda1–2 long, pda2 about 0.75 x pda1; remaining one (one to three) seta minute. Msts minute.
Abdomen. Bases of setae strongly pigmented, setae pigmented. Setae short, bacilliform or hairform (lsts, msts). Abdominal segments I–VIII (Fig. 62): pds1–5 approximately in line, pds2 and pds4 positioned slightly anteriad; pds1–5 very short, pds2 and pds4 slightly shorter. Sps minutely shorter than prs, long as pds1. Both dpls long as sps. Vpls2 2.5 x longer than vpls1. Lsts short, msts minute.
