Etymology [The species name was derived from Latin ferox, ferocious, courageous. It is not clear what this referred to, possibly to the contrast between the transparent cuticle and the long strong spines, both characters emphasized by Zelinka.] [details]
Taxonomic remark Zelinka (1928) erected the genus Habroderella for eyeless species described from juvenile stages of Echinoderes. The single specimen of Habroderella ferox available to Zelinka represented the last juvenile stage with a female inside. Zelinka (1928, pp. 257-258) was confused that the sternal plates were visible from trunk segments 2(!)-8. He addressed this to a still incomplete development of the sternal plates in the posterior segments and a forward movement of the anterior segments so the first pair of sternal plates appeared in segment 2 instead of segment 3 which would have been expected for species of Echinoderes.
Alternatively, the specimen might have been a representative of the genus Fissuroderes Neuhaus & Blasche, 2006. Amazingly, H. ferox revealed a middorsal spine on segments 4-9, whereas no described species of Fissuroderes possesses a middorsal spine on segment 9. However, the postembryonic development of species of Fissuroderes is unknown, and the spine on segment 9 may be lost during moulting to the adult stage. [details]
