0433E8254D1F5340B95DF713B1621D88.taxon	diagnosis	Diagnosis. Ptilocerembia qiului sp. nov. is assigned to the genus Ptilocerembia of family Ptilocerembiidae by the antennae with long erect setae and white distal segments, bifurcated MA in all wings, hind basitarsus with dense ventral setae and only one papilla, tergite X obliquely divided into two unequal sclerites with the area between the hemitergites depressed, MF with a hook, elongated HP, and the fused left cercomeres (Miller et al. 2012; Poolprasert and Edgerly 2014). Among the five known species of Ptilocerembia (see Suppl. material 1: table S 1), P. qiului sp. nov. is the most similar to P. catherinae based on the 10 R with a median convex along left margin, MF with a raised nodule near base of EP, and LC 1 with a large echinulate nodule (Poolprasert and Edgerly 2014). However, P. qiului sp. nov. can be distinguished from P. catherinae by the submentum with anterior margin truncate (concave in P. catherinae), MS with broad right half (absent in P. catherinae but similar to that of P. rossi), 10 LP and 10 RP broad (narrow in P. catherinae and other species), HP elongated and specialized apically (relatively short and simple in P. catherinae and other species) (Friederichs 1923; Poolprasert and Edgerly 2014). The dichotomous key in Poolprasert and Edgerly (2014) could separate P. catherinae as well as its similar species, P. qiului sp. nov. from other congeners.	en	Chen, Zhi-Teng, Xiong, Yuan, Jiang, Chao (2025): First record of the family Ptilocerembiidae (Insecta, Embioptera) from China, with morphological and molecular characterization of a new species.

0433E8254D1F5340B95DF713B1621D88.taxon	description	Description. Male: Body length (from anterior of maxillary palps to cercal apex) ca. 15 mm; color pale to brown (Fig. 2 A, B). Antennae at least 26 - segmented, most segments brown and covered by long erect setae, distal segments pale (Fig. 2 C). Head capsule dark brown (Fig. 3 A, B), near 1.5 times longer than wide, with reticular pigmentation on posterior 1 / 3. Eyes small, sides behind eyes rounded, gradually converging posteriorly. Clypeus broad, pale brown; labrum semicircular, dark medially, pale laterally. Maxillary palpi dark brown, five-segmented; labial palpi brown and short, three-segmented. Submentum dark brown, subquadrate, slightly wider than long, anterior margin truncate, posterior margin slightly concave, lateral margins slightly convex. Prothorax brown (Fig. 3 A), subquadrate, slightly wider posteriorly, much shorter and narrower than head, with subequal length and width, surface with deep transverse and longitudinal grooves. Meso- and metathorax generally brown, width subequal to head. Legs brown; hind basitarsus with single ventral papilla (Fig. 3 C). Wings pale brown (Fig. 4), with longitudinal pale stripes; MA of all wings forked subbasally. Abdomen dark brown (Figs 2, 5). Terminalia with tenth abdominal tergite completely cleft, hemitergites separated basally (Fig. 5 A – E). MS transverse, sinuate, near fusiform, with a posterior notch on right half. Hemitergite 10 L broad, subtrapezoidal, left margin expanded to ventral side; 10 LP constricted basally, right margin rounded, left margin greatly projected leftward medially, apex blunt and curved leftward. 10 R broad throughout, inner margin sinuate, with a median convex; MF with a long sickle-shaped hook (EP) and a raised nodule; 10 RP broad, subquadrate, apex with left angle pointed and right angle notched. LPPT produced as a subtriangular thin sclerite beneath 10 L, sharp LPPT-P pointing backwards. LC 1 tubular basally, elongated, inner margin with a large echinulate lobe apically. LC 2 shorter than LC 1, subconical, basal fusion with LC 1 slightly constricted. Right cercus slightly longer than left cercus; RC 1 slightly shorter than RC 2, both covered with long setae and tapering towards apex. H broad (Fig. 5 F, G), rounded, lateral margins obliquely convex; a slender curved sclerite present posterolateral to H. HP near as long as H; right margin mostly straight except expanded basally and convex apically; left margin convex at basal half, forming a denticulate ridge at apical half.	en	Chen, Zhi-Teng, Xiong, Yuan, Jiang, Chao (2025): First record of the family Ptilocerembiidae (Insecta, Embioptera) from China, with morphological and molecular characterization of a new species.
