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.
