Kings Mountain Milliped Fauna

species differed in its “slender body and peculiar form of the male geni- 
talia,” which he neither illustrated nor described verbally in his descrip- 
tion. Unfortunately, the male from the type series is lost, but collections 
made by Shelley in and around the type locality — Chapel Hill, Orange 
County, North Carolina — have produced male parajulids whose 
gonopods are virtually identical to that illustrated in Figure 5. This 
suggests that ectenes may be the species under consideration here, but a 
final judgment can only result from a comprehensive revision of 
Ptyoiulus in which female cyphopods are studied. Wray (1967) may have 
been correct in transferring ectenes to Aniulus, and this combination may 
be a senior subjective synonym of A. orientalis Causey, the only other 
parajulid known from the “Triangle” region of the state. 
Ptyoiulus impressus (Say, 1821) 
Fig. 6 
Adults of P. impressus were abundant in October and absent in April 
and July; juveniles were taken only in July and October. Thus, P. im- 
pressus appears to have a slightly different life history from that of P. ec- 
tenes, with summer growth and maturation preceding fall reproduction. 
Both species are uniformly gray and both were found in deciduous forest 
litter. Adult P. ectenes are slightly smaller and less robust than adult P. 
impressus, although this difference can be misleading and should not be 
the sole criterion for identification. The most reliable character is the 
configuration of the calyx of the peltocoxites of the anterior gonopod 
(Figs. 5-6, c, p,), which is flared and serrate distally in P. impressus and 
cupped and smooth in P. ectenes. As with its congener, the gonopods of 
P. impressus were essentially uniform. 
Ptyoiulus impressus ranges from the northeastern United States west 
to Indiana and south to western North Carolina and Kentucky (Cham- 
berlin and Hoffman 1958). Shelley (1978) deleted this species from the 
eastern Piedmont fauna, stating that it was known definitely only from 
the mountains and western Piedmont. The Kings Mountain region is the 
easternmost authentic locality in North Carolina.

This uniformly gray species is similar in appearance to both species 
of Ptyoiulus, but is distinguished by the decurved epiproct. Adults were 
collected in October from moist deciduous leaf litter in association with 
both species of Ptyoiulus. No juveniles were found. 
The genus currently contains only two species, T. parvior and T. 
setosior, both described by Chamberlin (1951) from Gatlinburg, Sevier 
County, Tennessee. Gatlinburg is about 200 km west-northwest of the
