Components. Theatops Newport, 1844, and Plutonium Cavanna,

 its original proposal, is removed from subfamily and left unassigned. 



Diagnosis (adapted from Attems 1926). A subfamily of moderate- 

 size to large cryptopids with 21 pairs of legs and pedal segments, 

 color generally yellowish, usually with lighter, pale or unpigmented, 

 patches lateral to bases of antennae in ocellar positions; complete paramedian 

 dorsal sutures present on tergites 2-20 (see Attems 1926, Fig. 433, 

 p. 369); caudal tergite nearly twice as long as penultimate, with or 

 without median suture; ultimate legs short, massive, and forcipulate, 

 heavily sclerotized, basal podomeres nearly as wide as long, with or 

 without dorsal and ventral teeth and spurs. 



Distribution. Southern Europe — coastal Croatia and Montenegro, 

 Bosnia-Hercegovina, southern Italy (Campania), Sardinia, Sicily, Spain, 

 and Portugal (Fig. 44); eastern North America generally east of the 

 Central Plains and south of the Great Lakes, from western New England 

 and the vicinity of Chicago, Illinois, to the south Florida Keys and 

 central, southern, and western Texas; and western North America from 

 western Chihuahua and northern Baja California Norte, Mexico, to 

 the southern Basin and Range Province in southern Nevada and south- 

 western Utah, westward to the Pacific Ocean and southwestern Oregon 

 (Fig. 10).
