Taxonomy
Order: OPILIONESSuborder: EupnoiSuperfamily: PhalangioideaFamily: Sclerosomatidae                                                                                 
Comments: Approximately 30 species in this genus have been identified as occurring in North America north of Mexico (Cokendolpher and Lee, 1993; Ingianni et al., 2011), with 16 recorded in North Carolina. However, the validity of several of these species is suspect, with several that will probably be determined to be synonyms of other species, e.g., davisi, speciosum, and zimmermani in North Carolina Burns et al., 2012; Shultz, 2018). According to Shultz (2018), moreover, recent phylogenetic studies indicate both that more species are waiting to be described and that the name Leiobunum may eventually be restricted to European species, requiring new generic names for most, if not all, of our species.

Comments: Shultz (2018) notes that crassipalpe appears to be known only from Arkensas, Missouri, and Oklahoma (citing Davis, 1934). He speculates that Maryland specimens, at least, may represent mistakes for L. vittatum. The same could also apply to our records for this species, both of which come from Roan Mountain, an unlikely locality for a Midwestern species.
