Arielulus pipistrelles (once included within
Pipistrellus), the Silver-haired bat
Nycticeius) (Roehrs
If serotines, butterfly bats and evening bats
do form a clade, the names Eptesicini and Nycticeini (or Nycticeiini) are both available: Nycticeini Gervais, 1855 very much has priority (Eptesicini wasn t used - I think - until published by Volleth & Heller (1984)), but Roehrs
et al. (2010) noted that more effort will be required to resolve the position of
Nycticeius [and what impact it might have] on the nomenclature of this clade (p. 1084) [the relevant part of the cladogram is shown here: if you need help, see the article on the vesper bat cladogram].
