Dendrothrips species with 9-segmented antennae

The presence of nine antennal segments among some species of Dendrothrips is considered to be a reversion from eight segments due to subdivision of the sixth segment ( Zhang et al. 2019; Wang et al. 2019). In this genus 11 species are considered to share this condition, although the degree of separation between the segments varies from the partial or oblique division found in D. degeeri and D. julatteni , to the complete division in the new species described below. Four of the Dendrothrips species reported to have 9-segmented antennae are also reported to have the pronotum with a pair of prominent posteroangular setae: D. eastopi from Europe; D. oatleyi and D. oleae from South Africa; and D. saniishi from Khazakstan. (zur Strassen 1968). The remaining eight species, including D. saudicus sp. n. have all the pronotal posteromarginal setae equally small. These eight species may be distinguished as follows.
