Type.

Haiti. Lectotype (designated by Barrios and Majure, in review). Photo of type material of L. weingartianus in Hartmann (1904).

Notes.

There has been some confusion around the type of L. weingartianus - Areces-Mallea (2017) designated a neotype of L. weingartianus considering that the original type specimen is likely not extant, however, the photo of the type material in the protologue ( Hartmann 1904) represents original material (Fig. 9C ) and thus should serve as the type for this species. Thus, the neotype designation by Areces-Mallea (2017) from Cote le Fer, Haiti, is superfluous. Although supposedly deposited in JBSD and NY, we have been unable to find those specimens. Likewise, we have been unable to locate the other specimens of L. weingartianus (Areces 5973, 6438, 6814, 6815, 6875) cited by Areces-Mallea (2017) and supposedly at NY, so those are not cited in our specimens examined here.
