Notes: Chamberlin’s brief discussion of the leg modifications is 
confusing. In the generic diagnosis leg 5 is described as being “nor- 
mal” while in the specific diagnosis, leg 5 is described as “less thick- 
ened, (the) fourth joint with a . . . subconical process on mesal side 
toward proximal end . . .” Thus B. oregona is immediately excluded 
from the very genus it is being described under! Chamberlin saw 
14 ocelli on each side, and gave the size as 7-7.5 mm. The male 
holotype is in poor condition. 
Where ecological data is available, the species appears to occur in 
duff from deciduous trees. Many samples of coniferous duff did not 
yield Bollmanella oregona. The species has been collected at eleva- 
tions from sea level to 1900', and thus appears to be primarily a 
coastal or river valley species, since many samples from higher eleva- 
tions did not contain B. oregona. This is the most widespread and 
common species of Bollmanella.

Type: Male holotype from 2 mi north, 6 mi east of Ashland, 
Jackson Co., Oregon (T38S/R3E/Sec 27), collected at an eleva- 
tion of 1200' by E. M. Benedict, 27 December 1971. 
Description: Male holotype. Length, 5.0 mm. Ocelli 8 on each 
side of head. Legpair 3 much as described for B. oregona. Legpair 4 
less enlarged, lacking basal femoral knobs present in B. oregona. 
Legpairs 5-7 of normal size. Anterior gonopods (Fig. 3) much as 
in oregona, but gonopod tip blunter. Posterior gonopod colpocoxites 
(Fig. 4) of reduced complexity When compared to following species; 
flagellum (/) short; sheathing structure ( s ) fused anteriorly to body 
of colopocoxite, which is broad and laminate, with minute teeth 
distally. T-shaped process of sternum present, but broken in making 
temporary slide of gonopods. Pigmentation light. 
Distribution: Known only from the type locality. The holotype 
came from a Berlese sample of Oregon oak and buckbrush litter on 
a steep slope.
