Striaria bombillus, n. sp.

Figs 14–17, 25–28

Types: Male holotype and two female paratypes from Little Bumblebee Creek, 47.6238°, -116.2972°, Shoshone Co., Idaho, collected 11 April 2003 by W. Leonard, deposited in the California Academy of Sciences. Parts of the holotype are mounted on SEM stub WS34-5, deposited with the specimens.

Etymology: The species epithet is a Latin noun in apposition, diminuitive of bombus, a bumblebee, and refers to Little Bumblebee Creek, the type locality.

Diagnosis: Similar to the preceding species, but differing in the fewer, shorter, less curved spinules and in lacking a lateral process of the anterior angiocoxites; possibly the lateral process has shifted somewhat to the mesal side of the anterior angiocoxites.

Description: Male holotype. Length, about 11 mm, width about 1.0 mm. Body form and secondary sexual characters as for the genus and Striaria aculeata, see above.

Gonopod anterior angiocoxites (Figs 25, 26) sharply bent posteriorad about two thirds their length at pronounced transverse ridge, proximal to ridge are 2 or 3 distinct rugae; tip (Figs 27, 28) with a few long spinules mesal, more laterally are more numerous but lower spinules in single row. Posterior angiocoxites robust, sheathing three or four flagellocoxites, lacking hook-like process seen in S. aculeata. Ninth legs as in S. aculeata.

Female paratype: Similar to male but without secondary sexual modifications; pygidium short, broad (Fig. 17).

Distribution: Known only from the type locality.
