Figs. 115–117

Types: Male holotype, male paratype and two female paratypes from WASHINGTON: Mason Co., W Beerbower Road, at W Schafer State Park Road, elev. 45 m., 47.1001°N, - 123.4706°W, collected 31 December 2004, by W. Leonard .

Diagnosis: Unlike any other species of Bollmanella , B. washingtonensis has pregonopodal legpairs three to seven enlarged, and pairs five through seven with femoral knobs.

Etymology: The species name notes that this species is endemic to Washington.

Description: Male paratype: Length, 10.5 mm. 18–20 ocelli in rounded, triangular eyepatch. Color pale tan, mottled light purplish brown. Segmental shoulders prominent, metazonital setae long, acute. Pregonopodal legpairs three to seven strongly encrassate, legpairs five, six and seven with femoral knobs. Anterior gonopods ( Fig. 115 ) slender, widely divergent, prominently curved near midlength, with acute subapical process as in the foregoing species. Posterior gonopods ( Fig. 117 ) with relatively short telopodites, coxites ( Figs. 116 , 117 ) two-branched, posterior branch shorter, tapering, curved laterad, anteromesal branch distally bifurcate, one terminal four times broader than other, slightly curved. Legpairs 10 and 11 as usual for genus.

Female 11 mm long, nonsexual characters as in male.

Notes: This widespread species could be considered as a Taiyutyla , since the pregonopodal leg modifications do not conform to the other species of Bollmanella . Nevertheless, the form of the gonopods indicates that it belongs in the latter genus.
