Dendrothrips saltatorDendrothrips saltatorBoth sexes fully winged. Body and legs yellow, antennal segments II and V–IX brown; fore wing grey. Antennae 8-segmented, segment VI without a transverse suture; segments III–IV each with a forked sense cone. Head with ocellar setae pair III scarcely 10 microns long; maxillary palps 2-segmented. Pronotum with one pair of prominent posteroangular setae. Metanotum with narrow elongate reticulation, median pair of setae small and arising medially. Metathoracic furca lyre-shaped, extending into mesothorax. Tarsi all 1-segmented. Fore wing apex bluntly rounded, antero-marginal cilia arising ventrally behind apparent margin, veinal setae minute, postero-marginal cilia straight. Abdominal tergites II–VIII median setae long and close together; lateral thirds of tergites with polygonal reticulations bearing fine internal sculpture lines; VIII with short postero-marginal comb of microtrichia. Sternites III–VII with three pairs of small postero-marginal setae.
There are about 55 species listed in the genus Dendrothrips, of which only four are known from Britain, and a further five from elsewhere in Europe. Most species in this genus are known from Africa, Asia and Australia. They all have the metathoracic furca elongate and "lyre-shaped", as do other members of the Dendrothripinae (Mound & Tree, 2016). However, in Dendrothrips species the fore wing is unusual with the antero-marginal cilia arising ventrally and well-behind the apparent anterior margin. D. saltator is similar to eastopi in having a pair of short but conspicuous pronotal posteroangular setae, but has the tergal sculpture forming almost equiangular reticulations.
Feeding and breeding on leaves, with adults recorded in Europe from a wide range of unrelated plants, including Abies [Pinaceae], Tamarix [Tamaricaceae], Anthriscus [Apiaceae] and Artemisia [Asteraceae]. In Britain, known only from Peucedanum officinale [Apiaceae].
Recorded in Britain only twice, and 79 years apart, but both times on the coast of Kent, first near Whitstable and then at Faversham (Bagnall, 1932; Collins, 2010b). This species is widespread in Europe with its range extending to Iran, Kashmir and Siberia (zur Strassen, 2003).
