Type notes:
1) Only a single specimen is involved as 
Shuckard, 1840a: 199, says “In the present genus [
Labidus, 
sensu Shuckard, 1840a, 
Shuckard, 1840b] I have seen but single specimens of any species.” 2) This taxon is based on a specimen of 
Labidus latreillii Jurine, 1807, 
sensu Haliday, 1836: 328, misidentification. 3) According to 
Horn & Kahle, 1936: 258, Shuckard’s collection was auctioned by J.C. Stevens (London).
