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.
