This genus has had a number of names applied to it, among which 

 one is proposed by Westerlund as taken from Da Costa (1778) but, as 

 indicated by Sherborne in the Index Animalium, Da Costa merely 

 quoted part of a polynomial phrase {Trochihis terrestris mortoni) 

 in his synonymy, from Morton's Northamptonshire (London, 171 2), 

 and did not use the word Trochilus in a generic sense. Moreover, if 

 he had, Trochilus had previously been used by Linne for a genus of 

 birds. There seems at present no reason to doubt that the first valid 

 name for the genus is Euconulus Reinhardt, while the typical species, 

 as will be evident from the following synonymy, is E. trochiformis 

 (Montagu) .
