Occurrence of two acarivorous species of the genus Feltiella (Diptera: Cecidomyiidae) in Okinawa, southern Japan, and redescription of F. acarivora (Zehntner)

Occurrence of two acarivorous species of the genus Feltiella (Diptera: Cecidomyiidae) in Okinawa,... Based on morphological features and molecular information, we record the occurrence of two acarivorous species of the genus Feltiella (Diptera: Cecidomyiidae) on some islands of Okinawa Prefecture, southern Japan. They are Feltiella acarivora (Zehntner), which is new to Japan, and Feltiella acarisuga (Vallot). F. acarivora is redescribed because the original description was incomplete. Feltiella acarivora was distinguished from F. acarisuga by having the following characteristics of male terminalia: hypoproct a little shorter than aedeagus, slightly tapering to a blunt apex with an apical ligule and gonocoxite with a hairy mediobasal lobe. For each species, we provide information on its geographic distribution, possible prey mites, and plant species on which the mites and Feltiella larvae or pupae were found. Through our surveys, we observed F. acarivora coexisting with at least eight species of tetranychid mites on various plant species, including fruit trees and vegetable crops. These observations suggest that F. acarivora and F. acarisuga contribute to the control of pest tetranychid mites in Okinawa. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Applied Entomology and Zoology Springer Journals

Abstract

Based on morphological features and molecular information, we record the occurrence of two acarivorous species of the genus Feltiella (Diptera: Cecidomyiidae) on some islands of Okinawa Prefecture, southern Japan. They are Feltiella acarivora (Zehntner), which is new to Japan, and Feltiella acarisuga (Vallot). F. acarivora is redescribed because the original description was incomplete. Feltiella acarivora was distinguished from F. acarisuga by having the following characteristics of male terminalia: hypoproct a little shorter than aedeagus, slightly tapering to a blunt apex with an apical ligule and gonocoxite with a hairy mediobasal lobe. For each species, we provide information on its geographic distribution, possible prey mites, and plant species on which the mites and Feltiella larvae or pupae were found. Through our surveys, we observed F. acarivora coexisting with at least eight species of tetranychid mites on various plant species, including fruit trees and vegetable crops. These observations suggest that F. acarivora and F. acarisuga contribute to the control of pest tetranychid mites in Okinawa.
