Type species: Acantholabus malaisei Heinrich, 1974 by original designation.</p><p>Diagnosis</p><p>Female antenna slender, bristle-shaped, with elongate basal flagellar segments, not widened beyond middle, with a white ring. Male antenna with distinct, elongate tyloids. Eye rather large. Gena short. Vertex abruptly sloping just behind ocelli. Temples short, sharply and roundly narrowed behind the eyes. Occipital carina with dorsal impression which does not reach level of eyes or hind ocelli. Clypeus strongly convex, weakly separated from middle field of face. Mandibles gradually narrowed, dorsally and ventrally carinated. Pronotum without carina interrupting transverse furrow. Upper margin of pronotum not thickened. Pronotal base gradually and uniformly curved. Mesoscutum rather strongly convex, almost as long as broad, very densely punctured. Notauli visible only at anterior third of mesoscutum. Mesoscutum matt. Subtegular ridge thick and sharp. Sternaulus weakly impressed at front half. Scutellum uniformly raised, laterally and apically carinate with high, sharp carinae, its horizontal part flat. Hind margin of metanotum with teeth. Horizontal part of propodeum in middle distinctly shorter than area petiolaris. Lateral propodeal carina indistinct, if present, situated at middle of area superomedia. Area dentipara short, with longer or short but distinct denticular apophysis. Juxtacoxal carina distinct. Propodeal spiracle relatively large, elongate, oval. Legs rather long and slender. Hind coxa elongate. Fore wing with areolet rather large, quadrangular, and symmetrical. Vein R straight and long. Vein 1cu-a interstitial. T1 petiole thick, strongly flattened at base.

Dentilabus iyoensis Kikuchi &amp; Konishi, 2018 is an exception, as it shares these characteristics with Acantholabus (Kikuchi &amp; Konishi 2018) .

Subtegular ridge defined. Speculum shagreened (Fig. 9G). Mesopleural pit consisting of short, deep horizontal groove (Fig. 9G). Sternaulus rather vestigal, visible at anterior part. Mesopleuron not punctured, shagreened, matt (Fig. 9G). Scutellum high, elevated above postscutellum, carinated laterally but interrupted at apex (Fig. 9H). Hind margin of metanotum with triangular projections opposite lateral longitudinal carinae. Propodeum tetrahedral in dorsal profile, its horizontal parts equal to area petiolaris (Fig. 9E). Propodeal carinae developed (Fig. 9F). Area basalis rather long. Area superomedia hexagonal, approximately as long as broad (Fig. 9B). Lateral propodeal carina present, joining area superomedia before its middle. Apophysis short but distinct (Fig. 9E). Juxtacoxal carina distinct. Propodeal spiracles elongate oval. Legs long and slender. Hind coxa elongate, 1.5× as long as broad. Hind femur 4.2× as long as wide. Basal portion of hind tibia slender, apical portion expanding evenly in profile. Ratio of length of hind tarsomeres (from base to apex) 2.1: 1.2: 1: 0.5: 0.6. Claws elongate, weakly curved. Fore wing with areolet large, quadrangular, receiving vein 2m-cu distal to its middle (Fig. 9K). Pterostigma broad. Vein 1 cu-a interstitial to M&amp;RS. Hind wing with distal abscissa of Cu straight, Cu about 3.5 times as long as cu-a, these veins almost opposite (Fig. 9K).</p><p>METASOMA. T1 without lateral carina, petiole short (Fig. 9C), 1.6 × as long as postpetiole (in profile) (Fig. 8). Gastrocoeli weakly impressed and elongate. Thyridia large and broad, distant from base of T2, with rather narrow interval between them with weak impression (Fig. 9I). Hypopygium triangular ventrally, without distinct longitudinal fold (Fig. 9J). Ovipositor sheath slightly projecting behind apex of metasoma (Fig. 9J).</p><p>COLOUR. Body mostly brown-yellow (Fig. 8), except: antenna (excluding scape ventraly and flagellomeres 7–11 dorsally), face medially (Fig. 9A), vertex (except lateral spots at eye orbit) (Fig. 9D), gena, pronotum dorsally, mesoscutum entirely, mesopleuron apically, T2–6 (except hind margin of T6), and hind tibia dark charcoal; flagellomeres 7–11 dorsally, face (except medial narrow band), fore coxa, pronotum ventrally and dorso-posteriorly, subtegular ridge, lower hind part of mesopleuron, hind margin of T6, T7 entirely, hind margin of S5, and hind margin of hypopygium ivory (Fig. 9J).</p><p>VARIATIONS. Female paratypes from Mt Laojun have darker metasoma with T2 mostly dark bean coloured (the hex code #330000) (Supp. file 1) and slightly longer apophysis (ratio of its dorsal length to its basal length 1.2 × vs 0.9 × in the holotype) (Supp. file 2).</p><p>Male</p><p>Unknown</p><p>Host</p><p>Unknown.</p><p>Distribution</p><p>China: Yunan.</p></div>	https://treatment.plazi.org/id/038E8785FFC8FF9EEB89D81BFEF9E535	Public Domain	No known copyright restrictions apply.
