Conspectus of the Phlaeothripinae genera from China and Southeast Asia (Thysanoptera, Phlaeothripidae) Author Dang, Li-Hong Author Mound, Laurence A. laurence.mound@csiro.au Author Qiao, Ge-Xia qiaogx@ioz.ac.cn text Zootaxa 2014 2014-05-29 3807 1 1 82 journal article 5377 10.11646/zootaxa.3807.1.1 239ef927-f13d-4898-b3a2-1cbb63c98215 1175-5326 4918122 2D4B429C-A8E3-4B02-9C15-286FCF7D04F1 Adelphothrips Priesner ( Fig. 118 ) Adelphothrips Priesner, 1953: 374 . Type species: Gynaikothrips tristis Karny , by original designation. No species of this genus is recorded from China , but two are described from Java, one from the Philippines , and one from Fiji . The holotype and paratype females of longisetosus Reyes have been studied (in ANIC), and antennal segment IV has three sensoria not two as given in the original description ( Reyes 1994 ). This genus belongs to the Liothrips- lineage, in which antennal segments III–IV have one and three sensoria respectively, and the prosternum lacks basantra, but in contrast to most species in that group the species of Adelphothrips have two pairs of equally well developed postocular setae ( Fig. 118 ). Another species from the Philippines , Adelphothrips ignotus (Reyes) comb.n. , is here transferred from Mesothrips because it has the character states typical of Liothrips- lineage. The only known specimen of ignotus (in ANIC), a male with expanded fore femora but no fore tarsal tooth, has the notopleural suture slightly incomplete on the right side, but complete on the left, and the metathoracic sternopleural sutures are well-developed.

Diagnosis : Head with cheeks slightly or distinctly narrowed at base; 2 pairs of postocular setae welldeveloped, one pair well posterior to the other ( Fig. 118 ); stylets usually about 1/3 of head width apart, retracted to postocular setae; antennae 8-segmented, III with 1 sensorium, IV with 3; pronotum with 5 pairs of well-developed setae, notopleural sutures incomplete or complete; basantra absent; mesopresternum transverse, sometimes narrow medially; sternopleural sutures absent or present; fore tarsal tooth absent in both sexes; fore wings parallel-sided, with duplicated cilia; pelta triangular; tergites II–VII with 2 pairs of wing-retaining setae; tube with straight sides, slightly shorter than head.
