Tubpontania crassispina (Thomson, 1871), comb. nov. Figs 3, 12. Nematus crassispina Thomson, 1871: 164. Notes on original descriptions and type material. Thomson (1871) described the female sex of the species from Jämtland, Sweden. Lindqvist (1954: 161) studied three females from Norway in coll. C. G. Thomson. He regarded P. crassispina as a distinct, high Nordic species and gave some of its characters. Zinovjev & Vikberg (1999: 295) designated a lectotype (ZML) from Jämtland and keyed and described the species. The lectotype was not studied again. Further description. Female. Lancet: radix with a group of 10 pores and 4 isolated pores; lamnium with 21 segments, apically slightly curved, annulus 2 with some 17 ctenidial spines, ctenidial spines on annuli 2–5 long and reaching aulax. Tooth 11 from base (Fig. 12) with numerous small serrulae, with basal third distinctly elevated, postcalcar rounded, cypsella long, not emarginated.
