Xylothrips flavipes

Body length 6–8.5 mm, about 2–2.3 times as long as wide, elongate. Head, pronotum, abdomen and disc of elytra testaceous; posterior of elytra and declivity dark brown; antennae reddish, club often brown. Frons transversely convex, densely and very finely punctured, very finely pubescent, with a few erect hairs next to inner margin of eyes; frons with punctures less fine and less dense than on clypeus, slightly rough, covered by fairly long, fine pubescence directed upwards. Clypeus finely and densely punctured, concave in an arc in front; clypeus with a transverse band of upwardly directed hairs towards base with a narrow median line; clypeal tufts of hairs as long as those on frons. Fronto-clypeal suture distinguished by different colour between frons and clypeus or shallow suture with vertical longitudinal furrow in middle ending on anterior margin of clypeus. First antennomere elongated, second antennomere sub-rectangular, each funicle segment with a rim of long hairs in middle, total length of funicle as long as or shorter than first antennomere of antennal club; first and second antennomeres of antennal club 1.3–1.5 times as long as wide, last antennomere rather elongated, about 2.5–3 times as long as wide. Pronotum with a distinct upwardly-directed uncinate tooth on anterolateral angle and a series of upwardly-directed teeth behind forming lateral border of rasp on anterior half; teeth gradually smaller and less erect towards summit; posterior border of rasp formed by small tubercles or granules, bearing yellowish-red, short, recumbent pubescence between teeth; basal half of pronotum with minute, moderately dense punctures in middle only, laterally shining, glabrous, tiny white hairs present close to infero-lateral margin; distinct, ridge-like lateral carinae extended to basal margin to form pointed posterolateral angles. Elytra 1.7–1.85 times as long as pronotum, 1.45–1.65 times as long as wide, disc parallel-sided, widest at middle of declivity.
