Removal of homonymy between Tedania (Tedania) fragilis Lambe, 1894 (1895) and Tedania (Tedania) fragilis Baer, 1906.
1. Tedania fragilis Lambe, 1894 (1895): 116 (type locality Aleutians and Vancouver Island, Northeast Pacific). Tedania fragilis Lambe, 1894 (1895) is the senior primary homonym of Tedania digitata var. fragilis Baer, 1906 but the two are clearly different species. The two species are both encrusting but differ notably in the size of their spicules. Styles of Lambe’s species measure up to 400 x 16 μm while those of Baer’s species measure up to 194 x 7 μm long. Tylotes of Lambe’s species are up to 262 x 6 μm while those of Baer’s species measure up to 170 x 3 μm long. Onychaetes of Lambe’s species average 275 x 3 μm in length while those of Baer’s species measure up to 107 x 1 μm long. The combination Tedania (Tedania) fragilis Lambe, 1894 (1895) is maintained (ICZN Art. 57.3).
2. Tedania digitata var. fragilis Baer, 1906: 18 (type locality Zanzibar, East Africa). Tedania digitata var. fragilis Baer, 1906 is the junior primary homonym of Tedania (Tedania) fragilis Lambe, 1894 (1895) and required a new name to remove homonymy (ICZN Art. 57.2).
3. Summary: Tedania (Tedania) fragilis Lambe, 1894 (1895) is the senior primary homonym of Tedania digitata var. fragilis Baer, 1906, and the name is maintained (ICZN Art. 57.2). Tedania (Tedania) fragilis Baer, 1906 is the junior primary homonym of Tedania (Tedania) fragilis Lambe, 1894 (1895) and in the absence of known synonyms required a new name to remove homonymy (ICZN Art. 59.1 & 60.3), for which Tedania (Tedania) baeri nom.nov. was proposed, named after Leopold Baer.
