Indolestes peregrinus ( Ris, 1916)

Figure 2 a-c

Ranges in Japan, Korea and very widely in China ( Wilson 2009). This species has the following synonyms: Lestes extraneus Needham, 1930 , Lestes monteili Navas, 1935 , and, probably, L coeruleus Fraser, 1924 ( Wilson 2009; Dow 2013). It was first described as a subspecies of the preceding species, as Lestes gracilis peregrinus ( Ris 1916) , basing on the differences in the dark pattern. The main of them are as follows: synthorax dorsal stripe with projections in peregrinus versus with straight margins in gracilis ; abdominal marks separated into anterior and posterior parts in peregrinus versus entire in gracilis( Ris 1916) . However, Asahina (1976) substantiated that I. peregrinus and I. gracilis are bona species. He pointed out that the above mentioned differences in the body pattern are reliable in spite of variability of its general expression, and added the important difference in the shape of the paraprocts, which is pointed in dorsal view in I. peregrinus and rounded in I. gracilis .
