Abstract

A new species of the genus Protacallodes Morimoto, 2011 (Molytinae), Protacallodes gracilirostris Tsuji & Yoshitake sp. nov., is described from Japan (Honshu, Kyushu, and the Nansei Islands), based on morphological characteristics including male and female terminalia. Renewed diagnoses for two Japanese species (Protacallodes masumotoi Morimoto, 2011 and Protacallodes ryukyuensis Morimoto, 2011) and a key to all species of the genus are also provided. Additionally, Protacallodes ryukyuensis is newly recorded from Kyushu (Fukuoka, Oita, and Kagoshima prefectures) and the Nansei Islands (Tokunoshima Island and Okinawajima Island), Japan.
