description: Key to second and third instar larvae of the subgenus Eugrapha
1 Type I of HY; PNa directed forwards, and not longer than anterior margin of PN, which is slightly prominent; MH less curved in upper third and their tips not reach anterior margin of AT5; central spine of IH evident, but very small. Southeastern Europe, Caucasus and Central Asia. Usually on the sands and close to water basin.............................. C. sublacerata
- Type II of HY; PNa slightly directed laterally; anterior margin of PN distinctly prominent and longer than apices of PNa; MH strongly curved in upper third and their tips reach at least anterior margin of AT5; central spine of IH usually indistinct or absent................................................................................................ 2
2 CT5 and AT5 widely fused on inner margin and partly in contact on external margin; AT5 partly covers inner part of IH (Fig. 3); MH very long and strongly curved above the middle; tips of MH traversing anterior margin of AT5 (third instar larvae) or reaching its anterior margin (second instar larvae) (Figs. 3, 7); IH 5–6.0 times shorter than MH. PN of 1.53–1.60 (1.55) linear width/length ratio (table 1). Southeastern Europe, Transcaucasia, Minor and Central Asia, West Siberia (south), Mongolia. Sands plots near saline basins.................................................................... C. contorta
- CT5 and AT5 fused on inner margin, but not in contact on external margin; AT5 not reaching IH; MH less curved above the middle; apices of MH reaching its anterior margin only; IH 4,5–5.0 times shorter than MH; CT5 with 16–22 setae in third instar larvae; PN of 1.60–1.76 (1.55) linear width/length ratio (table 1)................................................ 3
3 PN of no more than 1.70 linear width/length ratio; pronotum more narrowed basally................................ 4
- PN of more than 1.68 linear width/length ratio; pronotum less narrowed basally.................................... 5
4 Ridge of PNa with 1–2 setae in second-third instar larvae; CT5 with 15–22 stout setae in second instar and 18–24 stout setae in third instar larvae; LCT5 with 3–4 long setae in second instar and 7–10 long in third instar larvae. Europe. Mainly on the sands, near water reservoirs or far from water bodies....................................................... С. arenaria
- Ridge of PNa with 1–2 seate in second instar and 2–5 setae in third instar larvae; CT5 with less than 13–17 stout setae in second instar and 17–22 stout setae in third instar larvae; LCT5 with 2–3 long setae in second instar and 5–7 long setae in third instar larvae. Far East. Mesohygrophytic meadows and near water bodies........................................ C. elisae
5 Linear width/length ratio of PN 1.55–1.63 (1.60); PNa with 2–3 setae; tip of PY with 12–15 setae; CT5 with 16–18 stout setae. South Europe. Near freshwater and saline bodies................................................... C. trisignata
- Linear width/length ratio of PN 1.64–1.67 (1.66); PNa with 2–4 setae; tip of PY with 15–18 setae; CT5 with 18–20 stout setae. Southeastern Europe and Central Asia. Usually near different freshwater reservoirs........................ C. litterifera
