Cambalidae 
Cambala annulata (Say, 1821) 
Fig. 27 
Shelley (1978) reported that C. annulata seemed to prefer cooler tem- 
peratures, and this was apparent in the Kings Mountain region where the 
dark purple adults were abundant in both April and October. Only one 
adult, a female, was collected in July. Juveniles were taken in July and 
October but not in April. Hoffman (1958) indicated that individuals of 
this species were usually found grouped together, but in the Kings Moun- 
tain region this was true only of females; adult males were always found 
alone. All stages were collected from moist humus. Hoffman found no 
gonopodal variation in material from high elevations, and Shelley 
(1979b) noted homogeneity in the gonopods of C. annulata throughout 
its range. This was evident in the Kings Mountain material, as the struc- 
tures were virtually uniform. Cambala annulata has been reported from 
the northeastern and central subregions of eastern Piedmont North 
Carolina (Shelley 1978), and its distribution in the Appalachian Moun- 
tains was illustrated by Hoffman (1958). 
Paradoxosomatidae 
Oxidus gracilis (Koch, 1847) 
Causey (1943) reported nearly year around oviposition by O. gracilis 
under favorable conditions in a Durham County greenhouse, and Shelley 
(1978) collected fifth instar juveniles (adults are the seventh instar) in Oc- 
tober from William B. Umstead State Park in the eastern Piedmont. The 
preponderance of juveniles in October and April and of adults in July 
and October in the Kings Mountain region suggests that maturation oc- 
curs in the fall and spring and breeding in the late summer and early fall. 
White juveniles often populated several square meters of deciduous leaf 
litter, and shiny black adults also were common. Oxidus gracilis is nearly 
worldwide in distribution, and was introduced into the United States 
from the East Indies via imported soil in greenhouses (Causey 1943). 
Polydesmidae 
Pseudopolydesmus branneri (Bollman, 1887)

Pseudopolydesmus branneri is the sole representative of its genus in 
the Kings Mountain region; neither P. collinus Hoffman nor P. serratus
