Centipede Subfamily Plutoniuminae 



one from 16.8 km (10.5 mi) SW Bucks Lake, Plumas County, lacks 

 spurs on the right leg, which is considerably smaller than the left 

 and apparently regenerating. No individuals are available with only 

 one spur, but four are devoid of the structures, one from Oroville, 

 Butte County, and three from Canyonville, Douglas County, Oregon 

 (Fig. 17). More rarely, a specimen will lack a coxopleural spur, as 

 for example an individual from El Dorado County, which lacks that 

 on the right coxopleura (Fig. 16). 



Ecology. Labels with samples indicate that specimens were found 

 under logs and the bark of decaying logs or stumps. Most, however, 

 were encountered in litter, which was my experience during field work 

 in California. In June 1990 and April 1991, I found T. californiensis 

 to be abundant in litter in Yosemite Valley, Yosemite National Park, 

 Mariposa County, but I did not find a single specimen under a log. 



Distribution. The only specific published locality is the type locality. 

 Several authors have reported this species from California and Oregon 

 in general (Kraepelin 1903, Attems 1930, Crabill 1960, Kevan 1983), 

 but Shelley (1990a, Fig. 4) first delineated regions — along the western 

 slope of the Sierra Nevada and southern Cascade Mountains from Tulare 

 County, California, to Douglas County, Oregon, extending to San Francisco 

 Bay and the Pacific Ocean from Marin to Mendocino counties. The 

 northern limit, in southern Douglas County, Oregon, is unchanged, 

 but I have examined more southerly material from northern Kern County, 

 and the southern limit is thus in this county, in the southern part 

 of the Sequoia National Forest and the Sierra Nevada Mountains. In 

 May 1993, I spent a day searching unsuccessfully for T. californiensis 

 in the Toiyabe National Forest, on the eastern side of Lake Tahoe 

 in Nevada. The centipede may eventually be found in this area, but 

 it is currently known only from the California side of the lake. The 

 Oregon localities may be disjunct and represent a small, allopatric, 

 northern population, as there are no records between Josephine County 

 and Mendocino County, California. Because the type locality is the 

 only specific recorded site, I list below all records of T. californiensis 

 (Fig. 18).
