- <p><b><i>Podagritus propodealis</i> Pulawski, species nova</b></p><p>urn:lsid:zoobank.org:act: 84E2423F-F2E6-4BB8-ADD9-45747C897E94</p><p>(Figs 31–38, 39)</p><p><b>Origin of Name</b>.— <i>Propodealis</i> is a Neolatin masculine adjective derived from <i>propodeum</i>, with reference to the setose propodeal enclosure.</p><p><b>Recognition</b>.—This species and also <i>P. pilosus</i> sp. nov. are unique among the Australian <i>Podagritus</i> in having the propodeal enclosure mat, shagreened, and setose. They can be differentiated by the characters given under <i>P. pilosus</i> above.</p><p><b>Description</b>.—Clypeus in profile slightly convex near base; free margin of middle lobe with central part minimally concave, flanked on each side by concavity (about as wide as antennal socket) and rectangular tooth. Ventral end of occipital carina effaced. Mandible bidentate apically. Pronotal collar at the same level as scutum (which is relatively flat), with trace of lateral tubercle, with inconspicuous median sulcus. Scutum largely asetose except with inconspicuous setae along anterior and posterior margins. Omalus well defined. Mesopleural setae markedly shorter than midocellar diameter. Propodeal enclosure not delimited laterally by sulcus, mat, slightly shagreened, with shallow, sparse, inconspicuous punctures, with dense, erect setae that are longer posteriorly than anteriorly (longest setae about as long as midocellar diameter); median sulcus on posterior surface flanked by obtuse carina (carinae diverging dorsally). Posterior margin of submarginal cell with proximal portion five times as long as distal portion. Hindcoxa with obtuse dorsolateral carina.</p><p>Head including pedicel black, but mandible yellowish reddish (black basally and apically) and scape pale yellow. Thorax and propodeum black, pronotal lobe pale yellow in posterior half; humeral plate black. Foreleg yellowish ferruginous except foretarsus light brown. Midcoxa mostly light brown; midfemur yellow, darker dorsally; midtibia ferruginous; midtarsus light brown. Hindcoxa mostly yellow, black basally; hindfemur ferruginous, black basally; hindtibia ferruginous ventrally, dark brown dorsally; hindtarsomeres I–IV black, hindtarsomere V contrastingly ferruginous.</p><p>♀.—Orbital fovea with punctures markedly finer and sparser than adjacent vertex (Figs 32, 33). Flagellomere I 2.1 × as long as wide apically, flagellomere II 2.2 ×; apical flagellomere 1.7 × as long as wide basally. Erect setae of forefemoral venter basally and those of foretrochanter up to about one midocellar diameter long. Foretibia without spines on outer surface. Right forebasitarsus with four rake spines, left one with five spines. Hindtibia slightly clavate (Fig. 37). Tergum I 3.7 × as long as its greatest width, spiracle located slightly behind one third of its length. Lateral margin of pygidial plate straight in lateral view. Length 12.1 mm.</p><p>♂.—Unknown.</p><p><b>Geographic Rang</b> e.—Known only from the type locality in Western Australia (Fig. 39).</p><p><b>Flight Period</b>.—6 September, i.e. during the Australian early spring.</p><p><b>Material Examined</b>.— Holotype: ♀, Western Australia: Yanchep National Park (northern boundary) at 31.5063°S 115.6811°E, 6 Sept 2021, T.F. Houston collector (WAM, Registration Number 114459).</p>
