Abstract

An illustrated identification key is provided to 100 genera of Phlaeothripinae from China and Southeast Asia, together with a diagnosis for each genus, and comments on the species diversity. One new genus with a new species, Akarethrips iotus gen.n. & sp.n., and two new species, Heliothripoides boltoni sp.n. and Terthrothrips strasseni sp.n., are described from specimens collected in Peninsular Malaysia and Java respectively. Three Phlaeothripinae genera are synonymised, Mychiothrips Haga & Okajima syn.n. of Veerabahuthrips Ramakrishna, Syringothrips Priesner syn.n. of Gigantothrips Zimmermann, and Sauridothrips Priesner syn.n. of Gynaikothrips Zimmermann. In addition, four nomenclatural changes are included, Adelphothrips ignotus (Reyes) comb.n. transferred from Mesothrips, Karnyothrips palmerae (Chen) comb.n from Xylaplothrips, Xylaplothrips bogoriensis (Karny) comb.n from Brachythrips, and Oidanothrips notabilis Feng, Guo & Duan considered as a new synonym of Oidanothrips frontalis (Bagnall).

Fungus-feeding phlaeothripine Thysanoptera in the genus Holothrips from Australia and New Caledonia, with a structurally similar new genus, Holoengythrips

“…This occurs in both macropterae and apterae, but in macropterae the lateral margins of the mesopresternum are fused to the mesoeusternum. A similar posterior projection of the mesopresternum has not previously been reported from any species of Phlaeothripidae, although fusion of the mesopresternum and mesoeusternum is known in Asianthrips from southern Japan (see Dang et al 2014). The male has specialised areas of reticulation laterally on sternites (V) VI-VIII, but these are variable in their extent (Fig.…”

“…71). These character states suggest that this new genus is more likely to be related to the genus Hoplandrothrips in the Phlaeothrips-lineage than to Holothrips in the Docessissophothrips genus-group (Dang et al 2014).…”
