Morphological features of a Japanese fly that developes in orchids, Orchidophaga gastrodiacola Kato, 2006, assigned to the family Scathophagidae, are reviewed and this species is proposed as a junior synonym of Chyliza vittata Meigen, 1826, of the family Psilidae. Morphological features of specimens from Japan correspond well with those from European. Japanese specimens of this transpalaearctic...

In this paper, a procedure for conducting such analyses is discussed, which only requires the use of a measure of relationship between pairs of species, rather than a complete phylogeny, and which at the same time assesses the importance to be attached ...
