Pantinonemertes californiensis Gibson et al., 1982 , incertae sedis

( Figures 2C, 2D , 9A, 9B and 10C ; Tables 1 and 4) Pantinonemertes californiensis ( Gibson et al. 1982; Gibson and Sundberg 1992; Sun 2001).

Type material

Type material deposited at the Museum of Natural History in London, UK consists of sections of the holotype (female) 1981.1.2 and paratype (male) 1981.1.3.

Material examined

We examined sectioned specimens from the personal collection of Frank Crandall ( National Museum of Natural History , Smithsonian Institution , Washington DC, USA) collected from Millerton Creek marsh between Hwy 1 and the bay just opposite the Hwy 1 gate to the Borello ranch, Tomales Bay , CA, USA ( FC031 , FC034–37, FC085, FC112) and sections of one specimen collected by F. Crandall in July 1981 from the Bolsa Chica Ecological Reserve, CA, USA (a California State designated area near Huntington Beach) ( FC102–104 , FC 109–111 ). We anticipate these to be deposited with the NMNH. We also examined additional specimens collected by F. Crandall from Tomales Bay, CA, USA deposited at the NMNH: USNM 64138 (70% ethanol) and USNM 1076584–1076587 (slides) .

Figures

Figure 2. (A–B) Diagrams of anterior end of Prosadenoporus floridensis sp. nov. (A5ventral view; B5dorsal view); (C–D) Pantinonemertes californiensis (C5ventral view; D5dorsal view). Notes: cof, cerebral organ furrow; pf, posterior cephalic furrow; rhst, rhynchostome; sm, prosorhochmid smile.

Figure 9. (A–B) Transverse sections through the frontal organ of Pantinonemertes californiensis; (C–I) Prosadenoporus spectaculum comb. nov.: (C–F) a series of transverse sections through the tip of the head showing frontal organ twisting; lateral acidophilic regions of the frontal organ marked with arrowheads; (G) transverse section through the cerebral ganglia showing two neurochord cells (circled, insert); (H) transverse section through the proboscis insertion and anterior portion of cerebral ganglia showing contracted proboscis insertion muscles; (I) transverse section through the posterior region of brain showing beginning of the lateral nerve cords (asterisks) which appear sectioned longitudinally, presumably because of the severe contraction of the specimen during fixation. Notes: bgl, basophilic cephalic glands; cg, cerebral ganglia; fo, frontal organ; ogl, orange-G cephalic glands; vc, ventral brain commissure. Scales: (A–F), 50 mm; (G), 100 mm (insert, 50mm); (H–I), 200 mm.
