DISTRIBUTION. Holarctic. Usually may be found at the same pond with E. cucularia ; recorded together with E. divisa only in two localities in Yakutia .

SYNONYMY. Elgiva manchurica Rozkosny et Knutson, 1991 was described by a single male from China, Manchuria (= Heilongjiang prov.), Harbin (= 45.8 ° N 126.7 ° E). E. divisa have no ventral spines on the fore femur while E. solicita has. The authors did not find ventral spines on fore femur of the type specimen of E. manchurica and for this reason, compared it with E. divisa , did not compare it with E. solicita and described it as a new species. Sometimes the ventral spines on f 1 in E. solicita may be weak (often in Far Eastern specimens) or broken, or hardly visible because of folded fore tibia and femur. By all other characters E. manchurica is E. solicita : “bare prosternum … wing yellowish, distinctly darkened at apex of cell R 4+5 [= dark spot near apex of R 2+3]… much broader more massive male gonostyli [= surstyli as in E. solicita , authors gave drawings of gonostyli [surstyli], it is clear on both lateral and caudal projections]” ( Rozkosny et Knutson 1991: 67–69 and figs 1–2). We have not examined the holotype but we have three series from neighboring localities: Amur reg. (850 km North), Khabarovsk reg. (650 km North-East) and Primorsky reg. (500 km South-East from Harbin respectively), all these specimens belong to E. solicita . The ecological reasons (lowland at 45.8 ° N) also suggest E. solicita . Specimens of E. solicita from Far East of Palaearctic seem to have wing with stronger yellow tint and more distinct dark pattern than European, but western ones may have such wing colouration as well. So, E. solicita Harris, 1780 = Elgiva manchurica Rozkosny et Knutson, 1991 , syn. nov.
