MILLIPED GENUS DIXIORIA — HOFFMAN 7 



with both corners rounded on most segments, pores opening dorso- 

 laterally. 



Male gonopod rather simple; no coxal process, prefemoral portion 

 globosely swollen and with an erect, somewhat cuneiform process, 

 remainder of telopodite a slender, unmodified, strongly curved blade, 

 with one or two small subterminal processes and occasional sub- 

 terminal enlargement. Coxae separate from each other but connected 

 by a strong band of sclerotized tissue. 



Size of animals moderate, from 30 to 40 mm. in length, rather slender, 

 width about 20 percent of length. Dorsum black, with caudolateral 

 corners of paranota and anterior margin of coUum bright lemon yellow, 

 legs and other ventral surfaces yellowish tan to light brown. 



Kange: Southern Appalachian Mountains, specifically in and 

 adjacent to the Iron-Unaka mountain chain, from Bland County, Va., 

 south to Grandfather Mountain, N. C, and Roan Mountain, Tenn. 

 In general, the ranges in distribution of each form coincide closely 

 with separate mountains or mountain ranges. 



Species: Two, one of which is divided into six subspecies. 



Key to the known forms of Dixioria 



1. Coxal spines absent or represented only as a faint remnant on some of the 



caudalmost legs; all sternites with at least 8 setae; gonopod socket extend- 

 ing laterad past outer end of coxal acefcabula; process A of gonopods absent, 



process B greatly enlarged dactylifera 



Coxal spines present, conspicuous; most of the sternites glabrous, a few with 

 up to 8 or 10 setae; gonopod aperture not extending laterad past coxal 

 acetabula; process A of gonopods present, process B variable 2 



2. Distal end of telopodite of male gonopod with only one subterminal process 



(A) 3 



Distal end of telopodite of male gonopod with two subterminal processes (A 

 andB) 4 



3. Telopodite gradually tapering distad; distal end of prefemoral process bent 



lateral at a right angle or nearly so pela pela 



Telopodite conspicuously laminately expanded near end; prefemoral process 

 straight or nearly so pela acuminata 



4. Distal end of telopodite noticeably capitate (enlarged on the outer margin), 



processes A and B more or less coalesced; telopodite rather flattened in 



cross section pela brooksi 



Distal end of telopodite not especially capitate, its subterminal processes dis- 

 crete; femoral portion subterete in cross section 5 



5. Process B very large, becoming larger and broadly truncate distally; pre- 



femoral process bent at a right angle distally ; solenomerite very long. 



pela wrighti 



Process B small, digitiform, only slightly larger than A; prefemoral process 



cuneiform, not bent distally 6 



6. Prefemoral process broader, with an obtuse lobe on its outer edge . pela fowleri 

 Prefemoral process narrower, outer edge nearly straight but with a small 



subterminal indentation pela coronata
