Idyellopsis Lang, 1944 (Family Idyanthidae)
Lang (1944: 11) proposed the generic name Idyellopsis Lang, 1944 and fixed Idyellopsis typica Lang, 1944 as the type without describing or figuring it until 1948. According to ICZN Art. 13.4, the combined description or definition of a new nominal genus and a single included new nominal species, if marked by “gen. nov., sp. nov.” or an equivalent expression, is deemed to confer availability on each name. However, no such expression is apparent from Lang’s (1944) diagnosis (the genus is marked by “Gen. Idyellopsis, nov.” while the species is not mentioned until the end of the generic diagnosis as “Typus I. typica n. sp.”). Since the name I. typica is not accompanied by a description or definition that states in words characters that are purported to differentiate the species (ICZN Art. 13.1.1), or by a bibliographic reference to such a published statement (ICZN Art. 13.1.2), the name of the type species is effectively unavailable. Consequently, the generic name Idyellopsis Lang, 1944 also becomes unavailable since it does not meet the provisions of ICZN Art. 13.3 for genus-group names published after 1930 (type fixation is mandatory). The first author to make Idyellopsis available was Lang (1948: 413) who provided a differential diagnosis for the genus and its type species (by indication), Idyellopsis typica; hence the date and authorship of both should rest with Lang (1948). The genus has remained monotypic since. [details]
