Chiromyiformes
Chiromyiformes is an order of strepsirrhine primates that includes the aye-aye from Madagascar and its extinct relatives. Classification. The aye-aye is sometimes classified as a member of Lemuriformes, but others treat Chiromyiformes as a separate infraorder, based on their very reduced dental formula. Gunnell et al. (2018) reclassified the putative bat "Propotto" as a close relative of the aye-aye, as well as assigning the problematic strepsirrhine primate "Plesiopithecus" to Chiromyiformes. Evolution. The molecular clock puts the divergence of Chiromyiformes and Lemuriformes at 50-49 million years ago.
