DELTOTARIA MILLIPEDS—HOFFMAN 31 
DescripTION oF HOLOTYPE: Adult male, preserved just after 
moulting, at present colorless and soft, about 25 mm. in length and 6.0 
mm. in greatest width. 
The specimen differs from the description of D. brimleii in much 
the same ways as does mariana, but with the following noteworthy 
structural details: 
Labral setae about 12-13, clypeal setae about 16-16; in addition 
to these there are four or five submarginal setae in a row up to about 
the midlength of the genae, these not observed in the other species of 
the genus. Labral teeth large and distinct. Genae with median 
groove. 
Podosterna not strongly elevated, their median surface sloping 
evenly from the caudal edge down to the interzonal furrow. All 
sterna posterior to gonopods entirely glabrous, no subcoxal setae even 
on eighth segment. 
Caudal edges of sides of segments not noticeably set off by sub- 
marginal ridges or furrows; lower sides not produced into low knobs 
above the coxae. 
Gonopod aperture large and transverse, similar in shape to that of 
marvana, but the caudal edge is not margined and flush with the 
intercoxal surface of segment 7. Gonopod coxae small in proportion 
to size of the telopodite, differing considerably from mariana in this 
respect (compare fig. 1, b and d). Telopodite blade much less acutely 
bent in the postfemoral region, and subterminal expansion less pro- 
nounced. Process B of telopodite surpassed by a long, slender, 
solenomerite, evenly and slightly curved instead of noticeably recurved 
as in mariana and brimleiz. 
Remarks: It is unfortunate that only one imperfect specimen of 
this form is available for study. Its affinities are clearly with mariana, 
and I anticipate the discovery of intermediate forms by future collect- 
ing in the Pisgah and Balsam Ranges. If, however, the characters 
that serve to distinguish the two at the present (such as the presence 
of setae on the genal margins and their absence from the sternites in 
brimleardia) are found to be constant for the population of the Great 
Smokies, subspecific status for mariana would still be desirable. This 
latter form is very homogeneous over its known range, the males 
from Highlands showing no approach whatever to the characters of 
brimleardia.
