- <p><b><i>Sierola terpsilithus</i> sp. nov.</b></p><p>urn:lsid:zoobank.org:act: 1DD24760-AD0B-410C-8828-3064B52CC963</p><p>Figs 193, 195</p><p><b>Diagnosis</b></p><p>A somewhat nondescript species, identifiable by the combination of the head dorsally convex and compressed in lateral view (DH/LH ~0.48), frons not particularly broad, clypeus rounded and recurved apically, and basal wing cells sparsely setose. Closest to <i>S. badiorostris</i> sp. nov., differing in the setose basal wing cells, smooth frons microsculpture, long ventral setae on the metasomal sternites, and brown tinge of the mandible. Also similar to <i>S. helena</i> sp. nov., separated by the narrower, more parallel-sided head (WH/LH 0.79, OOL/WOT 1.39).</p><p><b>Etymology</b></p><p>From the Greek ‘ <i>terpsis</i> ’, ‘glad’, + ‘ <i>lithos</i> ’, ‘stone’, a literal translation of the type locality. It is a noun in apposition.</p><p><b>Type material</b></p><p><b>Holotype</b></p><p>AUSTRALIA – <b>Tasmania</b> • ♀; 1 km SSE of Gladstone; 40°58′ S, 148°01′ E; 29 Jan. 1983; I.D. Naumann and J.C. Cardale leg.; ex ethanol; ANIC 32-154887.</p><p><b>Description</b></p><p><b>Female</b></p><p>HEAD. Clypeal process semicircular to semi-elliptical, apex broadly rounded; dorsally weakly carinate, or with a low carina, distinctly visible only when viewed directly down towards mandibles; in profile weakly sloping dorsally but strongly rounded and recurved at apex. Mandible moderately narrow at base, distinctly broader on apical half, ventral margin distinctly concave; apical half of mandible strongly convex outwardly, teeth arrayed on frontal and dorsal surfaces, outwardly polished and shining distal of bend, coriaceous and dull basally; in ventral view evenly, moderately curved. Apex of mandible vertical, with equally strong teeth. Malar space almost absent. Dorsal setae of head about as long as flagellar width or scarcely longer. Frons moderately punctate, about 2–3 pit widths apart. Vertex and gena setae distinctly longer than frons setae but only about as thick, not particularly conspicuous. Frons microsculpture evident but smooth, shining. Vertex in dorsal view more or less straight; occipital margin narrowly rounded. Lateral ocelli distinctly separate from vertex crest by less than ocellus length. Ocellar triangle anterior angle weakly acute to right. Head more or less parallel-sided for some distance posterior to eyes. Eye setae short, only about as long as 1–2 ommatidia. Dorsum of head in lateral view slightly convex, head deepest on line through posterior margin of eye. Venter of head posterior to mandible convex in lateral view, with relatively sparse setae. Head weakly convex ventrally, genal angle absent. Side of head posterior to eye with a line of tesselate microsculpture extending from posteroventral margin of eye to vertex crest, distinctly different from smoother sculpting dorsally and ventrally. Gena ventral to eye flat; sculpture shining and faintly reticulate ventrally and posterolaterally, with narrow band of tesselate-scutellate sculpture extending diagonally from anterior margin of eye to posteroventral margin of head. Postgenal depression shallow, rounded. Antenna extending to pronotum.</p><p>MESOSOMA. Strongly dorsoventrally compressed. Anterior margin of dorsal pronotal area in lateral view evenly rounded. Pronotal setae longer than flagellar width. Propodeal disc laterally coarsely rugulose; median carina absent; transverse carina absent, brow of declivity broadly rounded; metapleural carinae complete. Profemur robust, about twice as long as wide and strongly convex dorsally, strongly laterally compressed, slightly arcuate in dorsal view.</p><p>METASOMA. Shining, with faint microsculpture laterally. S3–6 each with a pair of long erect setae, those on S5–6 about twice as long as preceding. Sixth sternum glabrous medially, with a mix of long and short setae laterally.</p><p>COLOR. Body entirely dark brown to black. Antenna brown on base of scape and apical flagellomeres, yellow medially. Mandible black to reddish brown. Coxae and femora brown, tibiae brown except at base and apex, trochanters and tarsi yellow.</p><p>WINGS. Membrane hyaline. Basal cells of fore wing sparsely setose, with one or two rows of setae in each cell. Cell 1M weakly convex posteriorly, corner posteroapical. Distal portion of vein Rs nearly straight, meeting anterior wing margin at right angle.</p><p>MEASUREMENTS.
