Xanthiopyxis is characterized by numerous knobs, spines and bristles covering the entire valve face. In this paper eleven species, of which seven are new species, are described and their stratigraphic ranges are presented: X. polaris Gran, X. norwegica Suto, sp. nov., X. brevispinosa Suto, sp. nov., X. teneropunctata Suto, sp. nov., X. lanceolatus Suto, sp. nov., X. circulatus Suto, sp. nov., X. reticulata Suto, sp. nov., X. obesa Suto, sp. nov., X. hirsuta Hanna and Grant, X. oblonga Ehrenberg and X. globosa Ehrenberg. In addition, resting spores which lack sufficient characteristics to identify easily are assigned to three informal species: Xanthiopyxis type A (knobbly type), X. type B (short spiny type) and X. type C (long spiny type).completedPaleobotanyalgaeArctic OceanCaliforniaCenozoicChaetocerotaceaeChaetocerotalesDeep Sea Drilling ProjectdiatomsDSDP Site 338DSDP Site 436DSDP Site 438IPODJapan TrenchLeg 38Leg 56Leg 57Mediophyceaemicrofossilsmorphologynew taxaNewport Beach CaliforniaNorth PacificNorthwest PacificNorwegian SeaOrange County CaliforniaPacific OceanPlantaesporestaxonomyUnited StatesVoring PlateauWest PacificXanthiopyxisurn:org.iodp:exp:38urnlargerWorkCitationcampaignurn:org.iodp:exp:56urnlargerWorkCitationcampaignurn:org.iodp:exp:57urnlargerWorkCitationcampaignurn:org.iodp:exp:38:site:338urnlargerWorkCitationstudyurn:org.iodp:exp:38urnlargerWorkCitationcampaignurn:org.iodp:exp:56:site:436urnlargerWorkCitationstudyurn:org.iodp:exp:56urnlargerWorkCitationcampaignurn:org.iodp:exp:57:site:438urnlargerWorkCitationstudyurn:org.iodp:exp:57urnlargerWorkCitationcampaignEnglishgeoscientificInformation-117.5400145.332933.370067.4707
