Califarcturus tannerensis (Schultz, 1966) Fig. 2 Microarcturus tannerensis Schultz, 1966: 20, 50, 51, pl. 14. Antarcturidae incertae sedis tannerensis.— Stebbins 2012: 1. Material examined . Holotype . USA, California, Tanner Canyon, 32°33’36”N, 118°55’40”W, 1298 m, green mud, 28 Jan 1960 ( Velero IV stn 6832), LACM Cr19600802 (male, 5.5 mm). [LACM label states: 236° from China Pt Light, San Clemente I., Channel Is, CA, 32°31’15”N, 118°54’02”W, 1320 m, Velero IV , 29 Jan 1960]. Supplementary redescription . Pereopod 2 carpus twice as long as merus, convex along flexor margin; propodus as long a carpus, almost linear; dactylus with unguis 0.7 length of dactylus body; ischium–carpus each with few marginal and submarginal setae, propodus with 4 mesial facial setae, dactylus with 1 strong mesial facial seta. Pereopods 3 and 4 similar, slightly shorter. Male pleopod 1 exopod ending in rounded setose lobe; posterior groove ending in deep fissure about 0.7 along length formed by a lateral lobe and a curved secondary lobe mesially; exopod 0.7 times length of endopod. Pleopod 2 endopod slightly longer than exopod; appendix masculina slightly curved, slightly longer than endopod, covered with fine setae. Pleopods 3–5 without marginal long setae. Uropodal endopod broader than long, with subdistal stout seta; exopod narrower than endopod, tapering, with longer distal stout seta. Distribution . Eastern Pacific Ocean, off USA, California; 1300 m. Remarks . Schultz (1966) stated that his type was a female but labelled his figure 10 of the fused penes as ‘first male pleopods’. The specimen is clearly a male; a female could be expected to have a wider midpereon. His dorsal habitus figure is reproduced here along with new illustrations of pereopod 2, pleopods 1 and 2, and the uropod, not figured in the original description. b d e Published as part of Poore, Gary C.
