Print Fact SheetOxythrips quercicola

Distinguishing features

Both sexes fully winged. Body legs and antennae yellow, antennal segment II sometimes slightly darker than I and III; fore wings weakly and evenly shaded. Antennae 8-segmented, III and IV each with short forked sense cone. Head wider than long; 3 pairs of ocellar setae, pair III just anterolateral to ocellar triangle, about as long as distance between posterior ocelli; maxillary palps 3-segmented. Pronotum with one pair of posteroangular setae; discal area with transverse sculpture lines. Mesonotum with paired anterior campaniform sensilla, median setae on posterior half of sclerite. Metanotum reticulate medially; median setae posterior to anterior margin; campaniform sensilla present. Mesothoracic furca with spinula, metafurca with no spinula. Fore tarsal pulvillus without an apical claw. Abdominal tergites with neither craspedum nor ctenidia; tergites V–VIII with faint transverse sculpture lines medially; VIII with no posteromarginal comb; IX with 2 pairs of campaniform sensilla; X sub-equal in length to IX, with long median split. Pleurotergites with irregular reticulate lines, without microtrichia or discal setae. Sternites without discal setae; setae S1 on VII arise submarginally.
Male similar to female; tergite IX with 2 pairs of short stout setae; sternites III–VI with small pore plate.

Related species

There are 39 species listed in the genus Oxythrips, mainly from the Holarctic region, together with a further 12 species known only as fossils. A key to 18 species from Europe is provided by zur Strassen (2003), but some of these species remain poorly defined, including halidayi, quercicola and ulmifoliorum. These are currently distinguished on the basis that halidayi is dark brown, and that in the yellow bodied quercicola ocellar setae III are longer than in the light brown species ulmifoliorum (zur Strassen, 2003). Wing reduction is reported only for halidayi, but there is little biological evidence that three species are involved. The genus is probably related to Anaphothrips, but is distinguished because all of its species have a single pair of pronotal posteroangular setae (Masumoto & Okajima, 2017a).

Biological data

Feeding and breeding on the leaves of Quercus [Fagaceae].

Distribution data

Collected infrequently in Britain and, with the exception of an historic finding in Berkshire, entirely from Scotland and the far north of England (Mound et al., 1976). The species was described from Scottish material (Bagnall, 1926), and is recorded elsewhere in Europe from Spain and Sicily (zur Strassen, 2003).
