Ethirothrips Karny

Remarks.

This genus currently comprises 37 species, of which eight are recorded from China: Ethirothrips brevis , Ethirothrips indicus , Ethirothrips obscurus , Ethirothrips chui and Ethirothrips virgulae from Taiwan, Ethirothrips longisetis and Ethirothrips vitreipennis from Hainan, and Ethirothrips stenomelas from Guangdong and Hainan. However, Ethirothrips virgulae is here newly recorded from mainland China at Guangxi. In this study, type-specimens of two species of Chen (Taiwan Agricultural Research Institute, Taichung) were checked, but unfortunately they are so poor that most characters could not be studied.

Diagnosis.

Head usually longer than width across eyes; eyes small, equally developed ventrally and dorsally; postocular setae well-developed; stylets long, V-shaped or sub-parallel; antennae 8-segmented, segment III with 2 sensoria, IV 4; pronotal major setae pointed or blunt, notopleural sutures complete; basantra present; mesopraesternum boat-shaped; metathoracic sternopleural sutures absent; wings, if present, with numerous duplicated cilia; fore tarsal tooth present in male; pelta broad, with two broad lateral lobes; abdominal tergites II–VII each with 1 pair of sigmoid wing-retaining setae in macroptera; tube surface smooth, without prominent setae; anal setae shorter than tube.
