【摘要】 <正> 丽熊蜂亚属 Nobilibombus 是 Skorikov,A.S.(1933)发表的一新属,但 Richards,O.W.(1968)将此属列为熊蜂属 Bombus 中的一亚属。此亚属的主要特征是上颚具六齿,颚眼距几呈方形,长于触角第3节。与高山熊蜂亚属 Alpegenobombus 相似,但后者颚眼距横宽,并短于触角第3节。 这个亚属主要分布于喜马拉雅山系,目前被确定的种:仅有 B.(N.)morawitziides Skorikov,及B.(N.)sikkimi Friese.但 B.sikkimi Friese 种根据 Friese 的原始描述此种与本亚属的主要特征是不相符的。本文记述本亚属二新种及污熊蜂亚属 Mendacibombus 一新种。更多还原
