1974 ] Shear — Milliped Genus Bollmanella 143 
branous serrations on mesal edge; irregular chitinized membrane at 
base ( fp ) ; sheath (s) large, enfolding flagellum, basally fused to 
anterior part of colpocoxite. Near point of fusion is large basal pro- 
cess ( b ) which is sharply elbowed and distally trifucate; colpocoxite 
with fimbriate ridge mesally and irregular, apical, laminate teeth. 
T-shaped process from posterior gonopod sternum much the largest 
in genus, arms extending laterad (Fig. 10). Pigmentation typical, 
but somewhat darker than in B. oregona . 
Mature females not collected. 
Distribution: In addition to the type locality: OREGON: Doug- 
las Co., Mack Brown County Park on Umpqua R., T25S/R7W, 
elev. 400', 7 February 1972, E. M. Benedict, cf . 
Notes: Collections at both sites were from Oregon oak duff. 
Bollmanella bifurcata n. sp. 
Figs. 11, 12 
Types: Male holotype, female paratype and other specimens from 
2 mi west of Joseph along Hurricane Creek, Wallowa Co., Oregon, 
collected 23 November 1968 by D. R. Malcolm. 
Description: Holotype male. Length, 9.2 mm. 20 ocelli on left 
side of head, 21 on right side. Legpairs 3 and 4 enlarged, approx- 
imately same size, both with small mesal femoral knobs. Legpairs 
5-7 decreasing in size, legpair 7 normal in size and form. Anterior 
gonopods (Fig. 11) upright, curved, with small lateral spine and 
large blunt mesal branch, presenting bifurcate appearance with telo- 
podite. Posterior gonopod colpocoxites (Fig. 12) rather smaller than 
usual, flagellum not observed, probably concealed by large sheath (s) 
which is free from coxite for most of its length. Body of coxite with 
large, spirally curved basal branch ( b ) bearing near its base a curved 
lamina. Sternal process (T) much less prominent than in other 
species. Pigmentation very light. 
Females as usual, similar in general appearance to males, but 
slightly larger and more robust. 
Distribution: Known only from the type locality. 
Note: This species is far removed from the other members of the 
genus, being found in the foothills of the Wallowa Mountains in 
extreme northeastern Oregon. This part of the state has not been 
much explored by biologists, and other species of Bollmanella may 
well ocur in other isolated mountain ranges. The region is also close 
to that studied by Loomis and Schmitt (1971), and in which they
