Diagnosis. Larva: Unknown.

Adults (modified from Smith 1990): Character states of family Nudomideopsidae . Idiosoma nearly round in shape; convex dorsally. First coxal plate extending nearly to or just beyond anterior edge of shield; suture line between third and fourth coxal plate ending posteriorly on posterior coxal group so that fourth plate does not reach medial edge; fourth coxal plate bearing small projection that partially or completely covers opening for insertion of fourth leg, with suture line at posterior edge distinct. Genital field bearing many (about 23) pairs of acetabula that are free in gonopore in males and embedded in ventral shield in females. Pedipalp tibia relatively elongate, slender and slightly constricted basally; bearing two slender setae ventrally at basal constriction.

Type species. Neomideopsis siuslawensis Smith.

Species included. Neomideopsis siuslawensis Smith (western North America) (monobasic), but there is an undescribed species from southeastern North America in the Canadian National Collection of Insects and Arachnids.

Distribution. North America.

Discussion. Smith (1983a, 1990) considered Neomideopsis to be a distinct genus. This treatment was followed by Smith & Cook (1991, 1999) and Smith et al. (2001, 2010) and by us here.
