Based on the material described below, the generic diagnosis for Xylochironomus should be emended as follows.</p><p>Adult male.</p><p>Frontal tubercles small, reduced. Acrostichals biserial, starting from the anterior scutum. Parapsidal suture thick (Fig. 2 A). Scutal hump with a weak hump, very low. Wing cuneiform and setose, anal lobe clearly reduced, apex of wing somewhat rectangular, with an interrupted costal extension (Fig. 1 A – C). Squama bare or with fewer than 3 setae. Mid and hind tibiae with 2 separated combs, only the outer comb with a long-curved spur, the length ratio of ta 4 / ta 5 in the fore and hind leg usually no less than 2.0. Segment VIII tapered anteriorly (Fig. 1 D) or indistinct in some teneral form. Insertion of lateral seta of superior volsella arising basal-dorsally or from basal margin; outer seta usually much longer than the length of the superior volsella. Inner margin setae of gonostylus short and sparse, unequal-distance or irregular. Anal tergite band separated, anal median seta tends to be uniserial if less than 6 setae, no tendency to be enclosed by a round and sclerotized anal tergite circle.</p><p>Adult female, pupa and larva.</p><p>See Cranston (2006).</p></div>	https://treatment.plazi.org/id/E314F5B8E9BC5B3FA59179DB63933EC6	Public Domain	No known copyright restrictions apply.

Both have an acute apex to the gonostylus, and the location of the outer seta of the superior volsella is more basal. However, in P. acristylum, the outer seta of the superior volsella is relatively short, not extending beyond the apex of the superior volsella, the squama has 9 setae, and the ratio of ta 4 / ta 5 in the middle leg is 1.5, and thus P. acristylum is not a member of Xylochironomus, but an atypical species of Polypedilum (Pentapedilum) .</p></div>	https://treatment.plazi.org/id/DB099F96B6285384BC8D6A65D4969E16	Public Domain	No known copyright restrictions apply.
