Acontista aurantiaca Burmeister, 1838 View in CoL ( Figures 3E, F View Figure 3 , 4B View Figure 4 )
Head. ( Figure 5B 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; between lateral-lateral ocelli about the size of ocelli, distance between lateral-central ocelli about 3× ocelli length. Vertex concave, surpassing imaginary line connecting the top of compound eyes; ps excavated, job protruding to compound eyes’ height. Frontal sclerite wider than long, T-shaped, and tripartite.
Prothorax. ( Figure 6B View Figure 6 ) Pronotum elongated, with smooth margins and small bump more visible in dorsal view, right below expansion of the supracoxal dilatation ( Figure 6B View Figure 6 1 View Figure 1 ). Supracoxal dilatation wide, rounded. Metazone constriction almost as wide as prozone without the lateral pronotal expansion ( Figure 6B View Figure 6 1 View Figure 1 ). Prozone discretely bulging in lateral view, metazone almost flattened with anterior part slightly bumped, in lateral view pronotum is thin, posterior end of metazone gradually sloping upwards ( Figure 6B View Figure 6 2 View Figure 2 ).
Prothoracic legs. ( Figure 7B View Figure 7 ) Forecoxae elongated, slightly shorter than pronotum ( Figure 7B View Figure 7 1 View Figure 1 ). Forefemora robust, large, well developed, and triangular, with straight dorsal margin ( Figure 7B View Figure 7 2 View Figure 2 ). Foretibiae dorsal margin curved ( Figure 7B View Figure 7 3 View Figure 3 ). All femoral and tibial spines the same colour as foreleg but with darkened tips ( Figure 7B View Figure 7 2 View Figure 2 , B 3 View Figure 3 ). Spination formula: F = 3DS/10-12AvS/5PvS; T = 12AvS/15-16PvS.
Wings. ( Figure 8B View Figure 8 ) Mesothoracic wings slightly longer than metathoracic, in resting position the latter projecting slightly beyond apex of former; both wings reaching the apex of abdomen; membrane of costal field of mesothoracic wing densely reticulated with cross veins branching in all direction. Forewing with green or yellowish colouration ranging from proximal region of wing to nearly end of the costal field, crossing wing diagonally in a straight line or discrete sigmoid shape; distalmost region not covered by this colouration, but hyaline and having two dark brown spots, proximal one smaller than distal one. A stigma under radius vein can present different degrees of pigmentation, from inconspicuous green denser zone to a visible small brown spot. In live specimens, when wings are closed, the dark spots overlap and create a pattern of black and orange stripes in the distalmost area of the wing. Hindwings with vivid orange colouration on costal field and upper part of discoidal and anal fields; right beneath orange portion is a hyaline portion, followed by dark stripe ranging from anal margin towards orange portion, followed by another small hyaline area near hindwing apex, the latter spotted with usually two irregular dark marks. This dark stripe can be thicker or thinner, varying among specimens but always presenting those hyaline regions and marks in this configuration. Veins on forewing green; veins on the costal field of hindwing orange, but longitudinal veins on discoidal and anal fields gradually becoming black.
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 abdomen which is usually covered by the wings.
Genitalia. ( Figures 9B View Figure 9 , 10B View Figure 10 , 11B View Figure 11 , 12B View Figure 12 ) CG8 with inner portion globose facing sbu, almost membranous with base moderately sclerotised with a sclerotised, rounded outer expansion; spb smooth with small dorsal sclerotised keel under globose part of CG8; agsl smooth, transversal, poorly sclerotised ( Figure 9B View Figure 9 ). CX8 larger at base in contact with CG8, inner margin membranous, its curvature at base rounded, outer margin relatively more sclerotised, cxal membranous with small sclerotisation, cxvl small, poorly sclerotised, with a few bristles, median part of the gp8 with constriction of the CX8 with outer margin sclerotised bearing a few setae then softly curving inwards, gpmo8 protruding outwards; gpal8 with multiple elongated setae at inner margin and a few more at apex; in lateral view, gp8 with vertical enlargement at medial side-to-side constriction, upper margin bending downwards forming duct-like structure at medial region, posteriorly bending upwards with a moderate curvature to gpal8; inner portion of gp8 with multiple setae at bending of upper margin towards gpal8 ( Figure 10B View Figure 10 ). gp9 membranous, poorly sclerotised, short, beginning near medial constriction of gp8 and ending near gpmo8; rh extending through the outer margin from ventral base of gp9 and smoothly curving downwards towards ventral portion, gptm9 membranous, almost inconspicuous; in lateral view, gp9 with sclerotised base widening just before middle, where a membranous dorsal expansion can be observed ( Figure 11B View Figure 11 ). gl9 broad, divided into a proximal and distal portion, the latter more sclerotised; a few bristle-like spines forming two groups in two clumps, in lateral view, respectively at upper and lower margins, having a few sparse bristles at distal portion; gpmo9 bulge short and tapered; upper margin of proximal portion curved inwards and bent over itself, forming an Ω-like cross section ( Figure 12B View Figure 12 ).
