Lasioseius manus De Leon, 1964
Lasioseius manus .—Lindquist, 1964: 301.
NOTE: Lindquist (1964a) referred to a species he called Lasioseius manus De Leon, which was supposedly described in a paper in Florida Entomologist, in press in 1964. We cannot find any description of a species by this name. Lindquist (1964a) did not make the name available, because it is an unpublished thesis, which was not produced in numerous identical and durable copies (ICZN Article 8.1.3.1).
