I, III, IV, V, VII. Type locality. North American Basin ( 39°46.5’N , 70°43.3’W ), 1330–1470 m . Type material. Holotype USNM 850201 (1 spm + 1 slide with sclerites); paratypes USNM 850202 (1 spm + 1 slide with sclerites), USNM 850204 (1 spm + 1 slide with sclerites), USNM 850206 (1 spm + 1 slide with sclerites), USNM 850208 (1 spm + 1 slide with sclerites). Remarks. Although USNM 850203 and USNM 850207 have labels indicating their status as paratypes , they were not originally designated as type material by Scheltema (1985 , p. 502), and thus have no type status.
