Name
Gastrothrips Hood – Wikispecies link – Pensoft Profile
Remarks
There are 38 species listed in this genus, of which five are recorded from China: Gastrothrips fuscatus, Gastrothrips fulviceps, Gastrothrips mongolicus, Gastrothrips eurypelta, also Gastrothrips monticola that was described from Japan by Okajima (2006)[1] but is here newly recorded from Inner Mongolia, China. One species, Gastrothrips fulviceps, was described by Hood (1937)[2] from Peru with the head and antennae colored distinctively, and this species was recorded from Taiwan by Kudo (1974)[3] as Nesothrips fulviceps (Hood). Gastrothrips mongolicus which was described by Pelikan (1965)[4] based on two females, was first recorded from China by Cao et al. (2009)[5] together with a new species Gastrothrips eurypelta. However, Cao et al. (2009)[5] indicated in a key that the postocular setae of Gastrothrips mongolicus are pointed at the apex, and was the only difference given from Gastrothrips eurypelta. However, the description of Gastrothrips mongolicus stated that these setae are blunt, also the pronotal major setae. Furthermore, although the description of Gastrothrips eurypelta did not mention the ventral shape of the eyes, the illustration indicated the eyes are slightly prolonged ventrally, as is illustrated for Gastrothrips mongolicus by Okajima (2006)[1]. Thus Gastrothrips eurypelta is probably a synonym of Gastrothrips mongolicus, and is excluded from the key below.
Diagnosis
Head usually as long as broad, or a little longer; eyes normal, usually equally developed ventrally and dorsally; postocular setae well-developed; stylets usually V-shaped; antennae 8-segmented, segment III with 1 or 2 sensoria, IV with 3; pronotal major setae pointed or blunt, notopleural sutures complete or incomplete; basantra present; mesopraesternum boat-shaped; metathoracic sternopleural sutures present; wings, if present, with or without numerous duplicated cilia; fore tarsal tooth present in male; pelta triangular, or 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.
