MILLIPEDS — KEETON 35 



Diagnosis: Distinguished from all other species in the genus by 

 the combination of the small size of the gonopods and the very short, 

 rather broad postcingular portion of the telopodite. 



Description: Length of male lectotype, 31 mm.; width, 7.5 mm.; 

 length of male paratype, 35 mm.; width, 9 mm.; length of female 

 parat3^pes, 38-39 mm.; width, 8-9 mm.; length of other male speci- 

 mens, 32-38 mm. ; wddth, 7-8.3. 



Collum subellipsoidal, ends of paranota narrowly rounded; para- 

 notal swellings present; ridges along anterior margins of paranota. 



Paranotal swellings evident on all segments. Paranota of segments 

 2-7 rounded, those of 8-1 1 more square (in some of Bollman's female 

 specimens the caudolateral corners of the paranota of the 9th segment 

 are slightly produced caudad). 



Sternum of 3d pair of legs with usual processes; sternum of 4th 

 legs with very weak indications of processes; sterna of 5th and 6th 

 legs without processes but a groove through center of sternum of 5th 

 legs. 



Coxal armatm'e moderately strong. 



Male gonopods small (about 1.6 mm. in telopodite arc length and 

 1.0 mm. in arc width) ; simple, curved gradually mesiad, then abruptly 

 cephalodorsad ; postcingular portion of telopodite short, rather broad 

 for most of its length, narrowing towards distal end. Prefemoral 

 spine rather large (bifid in lectotype only). 



Color: Dorsum dark brown, paranota yellow, tergites sometimes 

 narrowly margined posteriorly with yellow. 



Type specimens: Bollman's original description mentioned three 

 males and seven females. No holotype was designated. Two of the 

 females and parts of the three males are in the U. S. National Museum. 

 Inasmuch as Bollman mentioned most explicitly the specimen with 

 bifid prefemoral spines, and since this specimen is in relatively good 

 condition, the author hereby designates it as the lectotype specimen. 



Type locality: Bollman mentioned both Brookville and Hagers- 

 town, Ind. Chamberlin and Hoffman (1958) restricted the type 

 locality to Brookville. This is the locality at which all the males were 

 collected. Inasmuch as females are very difficult to identify, the 

 Hagerstown record is even a doubtful one for the species. 



New distribution records: 



Indiana: Clark County: upland oak woods, 1.5 miles southeast of Solon, Apr. 

 28, 1956 (1 cf), Hubricht. Kentucky: Fayette County: Lexington, Oct. 1, 1894 

 (1 c?), H. Garman; Richmond Road at Kentucky River, May 30, 1892 (1 cf), 

 H. Garman. 



Discussion: Bollman's description of this species mentioned the 

 bifid nature of the basal or prefemoral spine. I have examined all 

 three of Bollman's male type specimens. Only one shows this bifid
