cyanolaemus
Gr. κυανος kuanos  dark-blue; λαιμος laimos  throat.

Cyanolaemus
(Trochilidae; syn. Lampornis † Blue-throated Hummingbird L. clemenciae) Gr. κυανος kuanos  dark-blue; λαιμος laimos  throat; "The species upon which Cœligena was originally based (Ind. & Synop. gén. Troch., 1832, p. XVIII), included Ornismyia cœligena Lesson, which by tautonomy is the type. Unfortunately Lampropygia Reich. has been used for this bird and its allies and Cœligena for O. clemenciæ.  Replacing Reichenbach's name with Cœligena, we leave O. clemenciæ without a generic appellation and I propose Cyanolæmus,1  type Ornismyia clemenciæ Lesson.   ...  1 κυανεος blue, λαιμος throat." (Stone 1907); "Cyanolaemus Stone, Auk, 24, 1907, p. 196, 197.  New name to replace Coeligena Lesson not applicable.  Type, by original designation, Ornismyia clemenciae Lesson." (Peters, 1945, V, p. 80).
