群馬県の無翅雪カワゲラ相とその分布

抄録

I collected six species of wingless winter stoneflies in Gunma Prefecture during April 2011-June 2018. They be-longed to two genera of the family Capniidae, Plecoptera. Among them, Eocapnia nivalis (Uéno, 1929) was the most widely collected both in altitude and horizontally, which was found between 395 m and 1600 m above sea level. In Gunma Prefecture, Eocapnia sp. Ec3 (tentative name) inhabited only in the east foot of Mt. Tanigawa.
