Moulds, B. Moulds, specimen recorded (MSM). Description. Male (Plate 1A, Figs 2 A, 3). Head (including eyes) wider than mesonotum; ventral surface mostly olive-brown; postclypeus reddish-brown, dark brown along interior of tranverse grooves; anteclypeus dark brown; rostrum brown anteriorly, becoming dark brown towards apex; dorsal surface olive-brown to ochraceous with a prominent black band extending between the eyes and surrounding the ocelli and vertices; supra-antennal plate tending pale olive-brown, translucent; ocelli pink; with scattered silver pubescence throughout and long silver pubescence behind eyes. Eyes deep red in living specimens, often faded to brown in preserved specimens. Antennae dark brown, paler towards apex. PLATE 1. A: Ewartia oldfieldi (Distant) male; B: E. oldfieldi female; C: E. roberti n. sp. holotype male; D: E. roberti n. sp. female; E: E. lapidosa n. sp. holotype male; F: E. lapidosa n. sp. female. Scale bars = 5 mm. Thorax with scattered silver short pubescence. Pronotum olive-green, sometimes fading to pale brown in preserved specimens; a prominent, reddish-brown midline extending from back of head, with anterior margin as broad as distance between inner margins of eyes, this midline narrowing medially to a width slightly greater than the divide between lateral ocelli, then gradually broadening posteriorly until reaching margin of pronotal collar; pronotal collar mostly green to olive-green, reddish-brown medially. Mesonotum green to pale brown; midline broad, reddish-brown, with lateral edges distinctly yellow to pale brown; submedian sigilla brown to dark brown; lateral sigilla olive-brown, indistinct; cruciform elevation reddish-brown to dark brown; wing grooves and metanotum pale olive-brown to orange-brown, with silver long pubescence. Legs with coxae and femora green, olive-brown or pale brown; tibiae olive-brown to pale brown; tarsi pale brown becoming darker brown towards apex of claws. Wings with fore wing costal veins green to pale brown; pterostigma pale brown to reddish-brown; basal membranes orange; veins CuA, CuP and M green to pale brown; other veins brown to dark brown; veins CuA and M fused posterior to apex of basal cell; with eight apical cells. Hind wing veins pale brown or green, becoming darker on the posterior side of the apical cells; plaga surrounded by pale brown coloration anteriorly, otherwise transparent; with six apical cells. Opercula broadly rounded, pale green to pale orange-brown, with plates relatively flat. Timbals with five long ribs; short (intercalary) ribs present between all long ribs. Long ribs 1–3 and sometimes 4 attached to basal spur. Long rib 5 comparatively shorter. All ribs sclerotised, pale brown and of low contrast against timbal membrane. Abdomen. Tergites olive-green to pale brown; darker midline coloration> 1 mm wide, brown to dark brown, bordered by pale brown or yellow. Sternites olive green to pale brown or orange-brown, depending on state of preservation of the specimen. Genitalia. Pygofer, including dorsal beak, olive-green to brown; upper lobes prominent, with apices graduating to a broad point; basal lobes comparatively subtle, with apices rounded. Uncus pale brown, in lateral view extended and “duck bill”-like; lobes in ventral view small, medial lobe small, ovoid; claspers prominent with posterior section dark and outwardly curved, with apices blunt to broadly rounded ventrally and blunt laterally. Aedeagus with pseudoparameres extending well beyond theca; endotheca fleshy; ventral support not extending to the same extent as endotheca. Female (Plate 1B). Markings and coloration identical to male. Abdominal segment 9 green to olive, with a brown midline; ovipositor sheath extends 2.0– 2.5 mm beyond the apex of abdominal segment 9. Measurements. N= 14♂ 6♀. Means and ranges (in parentheses), mm; BL: ♂ 17.4 (15.8–18.3), ♀ 22.9 (21.6– 24.0); FWL: ♂ 22.4 (20.1–24.1), ♀ 24.8 (24.1–26.1); FWW: ♂ 7.6 (6.8–8.3), ♀ 8.2 (7.6–8.7); HW: ♂ 6.2 (5.7– 6.5), ♀ 6.7 (6.4–7.0); PW: ♂ 5.3 (4.8–5.5), ♀ 5.7 (5.4–6.0); AW: ♂ 5.4 (4.9–5.7), ♀ 5.7 (5.4–5.9). Distinguishing features. Ewartia oldfieldi has a conspicuous, broad, brown stripe medially along the dorsum, which extends from the proximal edge of the pronotum posteriorly to the apex of the abdomen. This feature distinguishes it readily from E. brevis, E. carina n. sp. and E. cuensis. The stripe is also present in E. etesia n. sp., E. lapidosa n. sp., E. roberti n. sp. and E. thamna n. sp.; however, in E. thamna n. sp. it is not present on the pronotum. In E. oldfieldi, the stripe is conspicuously broader at the anterior margin of the pronotum than the distance between the lateral margins of the lateral ocelli. This distinguishes it from E. roberti n. sp., which has a stripe is narrower than the distance between the inner margins of the lateral ocelli (compare Figs 2 A, 2B). Another useful feature in the shape of the stripe of E. oldfieldi is that it broadens posteriorly until it reaches the margin of the pronotum (Fig. 2 A). This distinguishes it from E. lapidosa n. sp., in which the stripe narrows distinctly before meeting the posterior margin of the pronotum (Figs 2 C, 2D). The shape of the stripe in E. etesia n. sp. is closely similar to E. oldfieldi. However, E. oldfieldi can be distinguished by its broader head width, which is ± 5.9 mm (cf
