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.
