The so called Bulgarian Ringlet was described in 1900 based on material collected in July 1899 by two of the first explorers of the Bulgarian butterfly fauna, Mary de la B. Nicholl and Henry John Elwes, during their expedition to the Rila Mountains (Elwes, 1900: 199). It was initially ranked as a subspecies of
Erebia epiphron (Knoch, 1783) and treated as such (Warren, 1936: 113) until 1977 when Arnscheid & Roos (1977: 110) elevated its taxonomic status to species level. Subsequently Higgins & Riley (1984: 279) and D’Abrera (1990: 158) again associated it with
epiphron, while Abadjiev (1993: 50), Tolman & Lewington (1997: 215) and Jaksic (1998: 14) treated it as a distinct species.
Erebia orientalis is a polytypic species. In addition to the nominate
orientalis from Rila another subspecies
infernalis Varga, 1971 (type locality: Vihren: 2300—2400 m [UTM grid reference 34TGM02]) occurs in the nearest Pirin Mts. The colonies of the species occupying higher parts of Stara Planina also differ morphologically, subspecies
macrophthalma Varga, 1999 (type locality: SW side of Botev Peak, (above Ray Chalet), 1700—1900 m [UTM grid reference 35TLH23]). All three groups of populations are well separated geographically. The male genitalia of the nominate subspecies are illustrated by Warren (1936: Pl. 28: Fig. 277) and those of the Stara Planina populations by Abadjiev (1995: 134: Fig. 20) and Jaksic (1998: 94: Fig. 75: 6). The main part of the species range lies inside the Bulgarian territory and the common name introduced by Tolman & Lewington (1997: 215) looked to be somewhat satisfactory (concerning it as a Bulgarian endemic), but very recently it was found also in Yugoslavia (Parker & Jaksic, 1996: 95, 96).
Type locality and type material
The exact position of the type locality in the Rila Mts was never mentioned by the author (cf Elwes, 1900: 199—200). Fortunately Nicholl’s paper (Nicholl, 1900: 66—67), written like a diary, helped to clear this situation:
‘On the 10th [July 1899]... we started for the Marica valley... Next day [11 July 1899]... we proceeded up the valley... till we reached the a beautiful open basin... This basin was decidedly moist, if not actually boggy... July 12th [1899] was... but we resolved stay where we were...’
Comparing the above citation with data label (lectotype labels below) and modern maps the exact locality should be fixed as Rila Mts: Maritsa Valley: 6000 ft [about 1969 m; just above the fusion of Tiha Maritsa and Prava Maritsa rivers] [UTM grid reference 34TGM17].
A lectotype of
Erebia orientalis was designated and illustrated in black and white by Warren (1936: 113, Pl. 68: Figs. 798, 799 [upperside], 806 [underside]). Later it was depicted in colour by Abadjiev (1995: Pl. XXXI: Figs 6—8).
