Complicatella , new genus

Type species: Bollmanella complicata Shear, 1971

Diagnosis: Differs from other genera treated in this paper in the complex posterior gonopod coxites which bear a long, basally arising flagellum and from two to seven variously shaped pseudoflagellar branches.

Etymology: The genus name is derived from the name of the type species and refers to the complex nature of the posterior gonopod coxites.

Included species: Besides the type, Complicatella pecteniphora , n. sp., and C. neili , n. sp.

Distribution: Western Washington, northern Idaho, northern Nevada.

Notes: This genus seems most closely related to Brunsonia , based on the complex posterior gonopod coxites. However, the anterior gonopods are very different, larger and more complicated and lacking the deep basal pore seen in Brunsonia . The scattered distribution of the genus is somewhat concerning, but further collection may fill in the gaps.
