Abstract

The genusAsteralobia(Diptera, Cecidomyiidae, Asphondyliini, Schizomyiina) was erected by Kovalev (1964) based on the presence of constrictions on the cylindrical male flagellomeres. In the present study, we examine the morphological features ofAsteralobiaandSchizomyiaand found that the male flagellomeres are constricted also inSchizomyiagaliorum, the type species ofSchizomyia. Because no further characters clearly separatingAsteralobiafromSchizomyiawere observed, we synonymizeAsteralobiaunderSchizomyia. Molecular phylogenetic analysis strongly supports our taxonomic treatment. We describe five new species ofSchizomyiafrom Japan,S.achyranthesaeElsayed & Tokuda,sp. n.,S.diplocyclosaeElsayed & Tokuda,sp. n.,S.castanopsisaeElsayed & Tokuda,sp. n.,S.usubaiElsayed & Tokuda,sp. n., andS.paederiaeElsayed & Tokuda,sp. n., and redescribe three species,S.galiorumKieffer,S.patriniaeShinji, andS.asterisKovalev. A taxonomic key to the JapaneseSchizomyiaspecies is provided.
