Acontista concinna ( Perty, 1832) View in CoL ( Figures 3C, D View Figure 3 , 4D View Figure 4 )
Head. ( Figure 5D View Figure 5 ) Triangular, wider than long. Compound eyes kidney-shaped and barely protruding, outer outline rounded. Ocelli small, as small as antenna’s pedicel; distance between lateral-central ocelli shorter than lateral-lateral ocelli; distance between lateral-lateral ocelli about 2× ocelli height, distance between central-lateral ocelli about 4× ocelli height. Vertex inconspicuously convex, just slightly exceeding imaginary line connecting the top of compound eyes; ps excavated but job not protruding to vertex’s height. Frontal sclerite wider than long, T-shaped, and tripartite.
Prothorax. ( Figure 4D View Figure 4 ) Pronotum medium-sized, with smooth margins. Supracoxal dilatation narrow, rounded. Metazone constriction almost as wide as prozone without lateral pronotal expansion ( Figure 4D View Figure 4 1 View Figure 1 ). Pronotum flattened in lateral view, thin, posterior end of metazone not sloping ( Figure 4D View Figure 4 2 View Figure 2 ).
Prothoracic legs. ( Figure 5D View Figure 5 ) Forecoxae elongated, slightly shorter than pronotum ( Figure 5D View Figure 5 1 View Figure 1 ). Forefemora robust, wide, well developed, and triangular, with straight dorsal margin ( Figure 5D View Figure 5 2 View Figure 2 ). Foretibiae dorsal margin straight ( Figure 5D View Figure 5 3 View Figure 3 ). All femoral and tibial spines the same colour as foreleg but with darkened tips ( Figure 5D View Figure 5 2 View Figure 2 , D 3 View Figure 3 ). Spination formula: F = 3DS/12-13AvS/5PvS; T = 13AvS/11-12PvS.
Wings. ( Figure 8D View Figure 8 ) Mesothoracic wings slightly longer than metathoracic, in resting position former do not project beyond apex of latter or only scarcely so; both wings reaching apex of abdomen; membrane of costal area of mesothoracic wing densely reticulated with cross veins branching in all directions. Forewing with homogeneous green or yellowish tone, same as body colour, but dark-phase morphotypes can occur where specimens are highly pigmented, and forewings have dark spots (see Scherrer and Aguiar 2021). Hindwings with vivid orange colouration on costal field and dark spot on distal region of the costal field, which rarely may fuse with dark colouration of discoidal field; black colouration with purple/blue reflexes on discoidal field, with hyaline area near wing margin. Veins in forewing the same colour as cells; veins in costal field of hindwing orange but longitudinal veins in discoidal and anal fields alternating between black and white with white crossveins.
Abdomen. Ovoid, usually wider than width of wings when in resting position. TG10 short, wider than long, convex. CS6 wide and long, obtuse, with small distal central fold towards the gpal8, high number of setae distally; cerci short, shorter than in male, not extending beyond CS6. In live specimens, a red/orange colouration can be observed in the region of the abdomen which is usually covered by the wings.
Genitalia. ( Figures 9D View Figure 9 , 10D View Figure 10 , 11D View Figure 11 , 12D View Figure 12 ) CG8 with inner portion rounded facing sbu, membranous, outer portion concave, almost membranous with outer margin consisting of two sclerotised denticle-like structures and ovoid sclerotised expansion; spb smooth; agsl smooth, transversal, poorly sclerotised ( Figure 9D View Figure 9 ). CX8 larger at base in contact with CG8, inner margin poorly sclerotised, outer margin relatively more sclerotised at the cxal, cxvl large, poorly sclerotised, with clump of bristles, median part of the gp8 with constriction of CX8 with outer margin sclerotised bearing many setae then softly curving inwards, gpmo8 membranous, globose, protruding inwards; gpal8 with many setae at inner margin with a few more at apex; in lateral view, gp8 with discrete vertical enlargement at medial side-to-side constriction, upper margin bending downwards forming a duct-like structure at medial region, posteriorly upper margin bending downwards with moderate curvature towards gpal8, which is curved upwards; inner portion of gp8 with multiple setae at bending of upper margin towards gpal8 ( Figure 10D View Figure 10 ). gp9 membranous, poorly sclerotised, short, beginning near medial constriction of the gp8 and ending near gpmo8; rh extending through outer margin from ventral base of gp9 and straightly curving upwards towards dorsal portion, gptm9 membranous; in lateral view, gp9 with sclerotised base widening just before middle, first half with base having a poorly sclerotised curved structure, second half of gp9 more sclerotised at upper margin than lower margin ( Figure 11D View Figure 11 ). gl9 wide, divided into a proximal and distal portion, with former more sclerotised; a few bristle-like spines forming three groups in three clumps, in lateral view, respectively at base, upper, and lower margins, with many sparse bristles at distal portion; upper margin of proximal portion curved inwards and bent over itself forming an Ω-like cross section ( Figure 12D View Figure 12 ).
