Sige californiensis

Type material: Not extant. Remarks: Chamberlin (1919) stated that the type of Sige californiensis was deposited at the Museum of Comparative Zoology, but today it is not present there and we consider it lost. Hartman (1936) synonymized S. californiensis with Sige bifoliata Moore, 1909. She did not mention examining Chamberlin’s material and the synonymy is likely based solely on a comparison of the descriptions. In the absence of type material it is difficult to verify or reject Hartman’s synonymy; Chamberlin’s original description is too brief and without any illustrations and we regard Sige californiensis as a nomen dubium. From the original description it would rather appear to belong to Pterocirrus (Pleijel 1990, 1991) and could possibly constitute a senior synonym of Pterocirrus montereyensis, but there is not enough information to assess this.
