Larva (modified from Smith 1983b , 1990 ): Character states of family Nudomideopsidae . First coxal plate with setae 1a long, third coxal plate with transverse muscle attachment scar relatively long. Adults (modified from Smith 1990 ): Character states of family Nudomideopsidae . Idiosoma nearly round in shape; convex dorsally. First coxal plate not extending to anterior edge of shield; suture line between third and fourth coxal plate ending medially near posteromedial angle on posterior coxal group so that fourth plate has a short medial edge. Genital field bearing five to seven pairs of acetabula that are free in gonopore in both sexes; fourth coxal plate bearing small projection that partially covers opening for insertion of fourth leg, with suture line at posterior edge moderately distinct. Pedipalp tibia stocky and slightly expanded ventrally; bearing two slender setae ventrally in proximal half of segment. Type species. Paramideopsis susanae Smith. Species included. Paramideopsis susanae Smith (western North America ), P. kyphus Cook ( New Zealand ). Distribution. Western North America and New Zealand . Discussion. Smith (1983b) proposed Paramideopsis as a distinct genus. This treatment was followed by Smith (1990) , Cook (1992) , Smith & Cook (1991 , 1999 ) and Smith et al . (2001 , 2010), and is followed by us here.
