Storchia cuneata Fan et Chen 1997 is recorded and redescribed from the Neotropical Region for the first time. Three species are described as new: Stigmaeus striatus Khaustov et Ermilov sp. n., Eustigmaeus dominicanensis Khaustov et Ermilov sp. n., and E. latisetosus Khaustov et Ermilov sp. n. In addition, some unusual morphological character states of Storchia cuneata are discussed.
