Xylaplothrips Priesner View in CoL

Xylaplothrips Priesner, 1928: 572 View in CoL . Type-species: Cryptothrips fuliginosa Schille, 1910 View in CoL , by monotypy.

In this study, species included in the genus Xylaplothrips View in CoL are limited to X. fuliginosus View in CoL and its close relatives.Although 11 species are now listed in this genus, only five species, X. fuliginosus View in CoL , X. fungicola View in CoL , X. togashii View in CoL , X. ulmi View in CoL and X. zawirskae View in CoL , are possibly included in the genus. The rest of the species could well be transferred from Xylaplothrips View in CoL to some other genus/genera, but this would require re-examining the original specimens. Two species listed in ‘species incertae sedis ’ by Mound and Tree (2019), X. ananthakrishnani View in CoL from Senegal and X. trinervoidis View in CoL from South Africa, have three sense cones on antennal segment IV, and are undoubtedly not closely related to fuliginosus View in CoL . Three species from Australia, X. acacia , X. anarsius View in CoL and X. gahniae View in CoL , and one species from New Zealand, X. collyerae View in CoL , could not be determined based on the descriptions at genus level and further study is required.

Xylaplothrips has only two sense cones on each of antennal segments III and IV, though Mesandrothrips has three sense cones on segment III and four on IV. However, these two are indistinguishable in characters states other than this sense cone formula. Moreover, both genera are possibly very closely related to the genus Karnyothrips which shows interspecific variations in the sense cone number of the antennal segments III and IV ( Okajima & Masumoto 2025): one to three sense cones on segment III, and two to four on IV. Considering this and the variations found in other genera classified into the Haplothripini (see introduction), Mesandrothrip s and Xylaplothrips appear to be more closely related than previously considered.

Only one species, X. togashii , is recorded from Japan, in the target area.
