Lacon cuneatus (Candéze) comb. n. 
Dilobitarsus cuneatus Candéze, 1865 : 8. 
LECTOTYPE (present designation). FRENCH GUIANA: 4, Bar. Cayenne; 
Janson coll. 1903 : 130; Dilobitarsus cuneatus Cdze. Type (El.n) (e coll. de 
Mniszech) [Janson] (BMNH). 
The absence of Candéze’s determination label is probably due to Janson (see 
p- 276). 
Lacon delagrangei (Buysson) 
Adelocera delagranget Buysson, 1891 : 134. 
Lacon delagranget (Buysson) Fleutiaux, 1926 : 93. 
LECTOTYPE (present designation). Syria: 9, Syrie, Amanus C.D. 1891; 
Adelocera delagrangei nov. sp. [Buyss.] (MNHN, Paris). 
Lacon discoidea (Weber) comb. rev. 
Elater discoidea Weber, 1801 : 77. 
Elatey pennata Fabricius, 1801 : 239. [Synonymized by Schoenherr, 1817 : 302.] 
Lacon discoidea (Weber) Fleutiaux, 1926 : 93. 
Zalepia discoidea (Weber) Arnett, 1969 : II. 
Elater discoidea Weber. The description was based on an unrecorded number of 
specimens from ‘America boreali’. Weber’s types are presumed lost or destroyed 
(Lane, in litt.). 
Elater pennata Fabricius. LECTOTYPE (present designation). U.S.A.: 9, 
[abdomen damaged by Anthrenus] pennata Fab. Caroline, coll. Bosc. [? Bosc, on 
green paper] (MNHN, Paris). 
Schoenherr regards pennata as the valid name, but since Fabricius (1801 : 252) 
refers to Weber under Lucanus piceus, it seems probable that his work appeared 
after that of Weber. 
The species is distinctive and there is no good reason why the traditional synonymy 
should be rejected.
