Taxonomy 1. In the introduction to his monograph, Lang (1948: 7) stated that whenever the type species of a genus was not explicitly indicated by him, he considered the first species to have been described in that genus as the type (“Wenn der Genotypus für eine Gattung nicht angegeben wird, betrachte ich die zuerst beschriebene Art als solcher.”). Such a rule is not among the allowed criteria for ascertaining type fixation in the original publication (ICZN Art. 68), and thus the status of being the “oldest species” assigned to one of Lang’s genera does not in and of itself confer type status on that species. The term “designation” must be rigidly construed (ICZN Art. 67.5, which applies to Art. 69 for subsequent designation as well).
2. Subsequent designation by Boxshall (1979: 204). According to Seifried and Schminke (2003: 32) the family-group name Aegisthidae Giesbrecht, 1893 [see Holthuis and Vervoort (2006) for correct publication date] is a senior subjective synonym of Cerviniidae Sars, 1903. [details]
