Adraneothrips alajuela Mound and Marullo.

Previously known only from Costa Rica, four females were taken on Hawaii in July, 2016; two from a dead branch of Metrosideros polymorpha [ Myrtaceae ] at Tom’s Trail, 30 km southwest of Hilo, one from dead branches of Metrosideros polymorpha at the Volcano Research Station, and one from a dead branch in a garden at Volcano. Generally medium brown in color ( Fig. 6 ), this species has abdominal segment II yellow with its anterior margin weakly shaded, and tergites VI and VII lighter brown. The compound eyes are prolonged ventrally, and the pelta has very small lateral wings and bears a pair of campaniform sensilla ( Fig. 7 ).
