Abstract:
To describe and properly allocate Enantigonodesmus adisi n.sp. and Docodesmus amazonicus n.sp.,
both from nonflooded upland forest near Manaus, Amazonia, Brazil, the holotypes of Enantigonodesmus
planus SILVESTRI, 1898 and Stictodesmus laetus SILVESTRI, 1898 have been revised, both deriving
from near Carácas, Venezuela. Based on the particularly complex gonopod structure, the oligotypic
Enantigonodesmus SILVESTRI, 1898 is considered as one of the most disjunct and nicely defined genera
among Pyrgodesmidae. while the discovery in Central Amazonia of the prolific, rather strongly variable,
chiefly Caribbean Docodesmus COOK, 1896 is rather surprising zoogeographically.
