DELTOTARIA MILLIPEDS—HOFFMAN 23 
the dorsal side of the peritremata. Lateral margins of segments 2—4 
not completely set off, the submarginal groove not attaining the 
caudal edge of the paranota. Tergites typically smooth and polished, 
the anterior half of the metatergites slightly coriaceous, upper surface 
of paranota usually distinctly wrinkled. 
Sterna smooth and glabrous except for several posterior to the 7th 
segment; sloping upward gradually from the interzonal furrow to 
an acute-edged shelf between the second leg pair of each segment, 
not produced into subcoxal spines or lobes. Legs of normal length 
and form, both coxae and prefemora with ventrodistal spines. 
Coxae of gonopods large, almost in contact mesally, connected by a 
partially sclerotized sternal remnant; EACH COXA WITH AN ELONGATE 
SUBCONICAL APOPHYSIS WHICH PROJECTS DISTAD TOWARD OR OVER 
BASE OF THE PREFEMOUR, latter typically without prefemoral process; 
coxal macrosetae on the dorsal side of the apophysis instead of the 
ventral as in Pachydesmus. Prefemur subglobose, with long fine 
setae, prolonged distally without interruption into the slender, 
arcuate telopodite blade, which is unbranched or modified except 
for various subterminal expansions or lobes, the solenomerite always 
terminal. 
Anterior edge of ventral ends of pleurotergite of third segment in 
females produced cephalomesad into a large rounded elongate lobe 
forming the point of attachment of the second leg pair, but the adjacent 
edge of the segment is not elevated into a high flange as in the other- 
wise similar corresponding region in Pachydesmus. Median branches 
of the tracheal apodemes of second sternite expanded and partially 
fused, the surface thus formed somewhat larger and more removed 
from the coxae than in related genera. 
Range: Extreme southern Appalachians and adjoining Piedmont 
regions in North Carolina, Tennessee, and Georgia, and doubtless 
also South Carolina. 
Species: The following six, separable by the characters stipulated 
in the key and illustrated or discussed below: brimlezi, mariana, brimlear- 
dia, tela, lea, and philia, the second and fifth named being new species. 
ReEwATIONSHIPS: The genus Deltotaria is a member of the group of 
xystodesmid genera endemic to eastern United States in which the 
telopodite of the male gonopod is composed of a subglobose enlarged 
prefemoral division (usually with a distinct prefemoral process) which 
abruptly narrows into a normally slender, unbranched, spirally coiled 
or subfalcate blade. In all of these genera the body form is broad 
and compact, the ozopores located dorsally, the sterna broad and 
unarmed, and the gonopod aperture large and transversely oval. Most 
of the generic names in this ensemble were originally proposed for one 
or only a few species, and subsequent discoveries have in many cases
