Two new and three known Japanese species of genus Pseudasphondylia Monzen (Diptera: Cecidomyiidae: Asphondyliini) and their life history strategies

Abstract

Two new Japanese species, Pseudasphondylia kiritanii and Pseudasphondylia elaeocarpi (Diptera: Cecidomyiidae), are described, and the three previously known Japanese species of Pseudasphondylia are redescribed. Geographical distribution, host plants, and biological notes are provided for each species. Morphological characters of Pseudasphondylia are discussed in comparison with some other genera of Asphondyliini. Keys to the world species of Pseudasphondylia males and to immature stages of Japanese species are provided. Possible host alternation by P. matatabi and P. kiritanii is suggested based on the results of previous and current studies. © 2005 Entomological Society of America.
