We review the fossil material from the Swiss middle Eocene site of Egerkingen allocated to Adapis sciureus and transferred to the new genus Microadapis. Three species at least are represented in this assemblage. Microadapis sciureus is represented only by the holotype, whose affinities appear to lie with the North American Smilodectes. Most of the original hypodigm is allocable to the new genus Simonsia, which does bear the affinities to Adapis suggested by earlier authors for sciureus. Two specimens are placed in the new genus, Chasselasia, which may be related to the extant galagids.
我们回顾了来自瑞士中始新世埃格金根遗址、曾被归入松鼠猴狐猴（Adapis sciureus）并被转移到新属小狐猴属（Microadapis）的化石材料。这个组合中至少有三个物种。松鼠猴狐猴小狐猴仅由正模标本代表，其亲缘关系似乎与北美斯氏狐猴（Smilodectes）有关。大部分原始副模标本可归入新属西蒙斯狐猴属（Simonsia），它确实具有早期作者认为松鼠猴狐猴所具有的与狐猴属（Adapis）的亲缘关系。有两个标本被归入新属沙氏狐猴属（Chasselasia），它可能与现存的婴猴科动物有关。
