Carterocephalus dieckmanni soyosanus Murayama, 1983

Entomotaxonomia 5(4): 284.

Labels : “Soyosan (in Chinese character)/ S. Korea (in Chinese character)/ 24-4-1944 / MURAYAMA,” “dieckmanni/ soyosanus/ HOLOTYPE (in red).”

A male specimen was designated as the holotype by Murayama (1983), and the specimen was retrieved in LBM ( Figs. 37–39 ; Dried Insect Database Reg. no. 1500022017).

The subspecific name soyosanus has not been popularized in Korea. No subspecific name is assigned to dieckmanni Graeser, 1888 in two recently published butterfly books in Korea ( Joo et al. 1997, Kim 2002).

Evans (1949) recognized 4 subspecies of dieckmanni based on the difference in the central band on the ventral side of the hindwing. Even a brief examination of specimens tells us that some of the subspecific names should be synonymized due to clinal variation.After examining 57 specimens (1 from Russia, 3 from Korea, 2 from Northeast China, 13 from North China, 37 from West China, and 1 from Myanmar) in the Tsukiyama Collection , we found that the markings used by Evans (1949) as diagnostic characters to distinguish subspecies actually represent a clinal variation. The difference between ssp. dieckmanni and ssp. gemmatus Leech, 1891 is not clearly defined, and so is the difference between ssp. minor Evans, 1932 and ssp. watsoni Evans, 1932 . Consequently, no subspecific name is necessary for Korean populations of dieckmanni .

We consider soyosanus a junior subjective synonym of nominotypical dieckmanni Graeser, 1888 , syn. nov.
