From editor or global species database
Status The work by Youluo [= "Editorial Board"] (1978) was published by a group of authors, but no individuals are identified as authors of the publication, specific sections or the new taxa. According to ICZN Art. 14, names published anonymously after 1950 are not available. The genus was also referred to by Huang (1983) and Yu (1983), but they did not designate a type species (Youlou 1978 designated the single species L. gracilis as type), hence the name is not available from these publications either.
