Type locality. Australia, Queensland, Kutini-Payamu (Iron Range) National Park, Cooks Hut Camping Area, Portland Roads Rd Queensland.

Distribution. Australia, Queensland.

Etymology. Species named after the type locality of Kutini-Payamu National Park.

Diagnosis. Main characteristics as for the genus in terms of shape, coloration and FW venation. M. kutini is characterized by its large size, long FWs as in M. jharnae and male genitalia widened laterally, with paired globular pseudepiphallic lophi more developed than in M. jharnae .

Description. Size large. Coloration mostly dark brown and orange brown, contrasted ( Fig. 14 View FIGURE 14 ). Head rounded, eyes little protruding, occupying 38% of head width in dorsal view. Vertex with six wide longitudinal black bands on yellow background, sometimes almost fused together, the median ones punctuated ( Fig. 15A View FIGURE 15 ); back of eyes with a yellow line. Fastigium orange brown, black apically; twice as wide as scape, slightly widened apically. Ocelli yellow. Scapes mottled with yellow and dark brown; antennae brown with yellow brown rings. Frons black, with a thin yellow median spot, face mostly dark brown with four yellow spots, mouthparts pale ( Fig. 15B View FIGURE 15 ). Maxillary palpi brown with yellow rings. Pronotum: Dorsal disk dark brown to black, mottled with orange; lateral lobes homogeneously black. Brachypterous, FWs reaching one third of abdomen length in both sexes. FI-II orange brown with dark brown spots; TI-II dark brown with a narrow yellow ring; tarsomeres dark brown, yellow basally. Leg III orange brown basally, dark brown to black apically, including posterior parts of FIII, knee and TIII. Abdomen brown, variable. Cerci orange brown with dark brown rings.

Male: FWs narrow, dorsal and lateral fields gray brown, slightly translucent, with a small yellowish basal spot (not visible in fixed specimens); veins little contrasted ( Fig. 16A View FIGURE 16 ). Vein 1A not bisinuate, with a wide flat angle (ca. 120°). Harp longer than wide, its posterior corner slightly raised, with one bisinuate oblique vein, its inner sinuation angular, and one thin vein in anterior corner. CuA not curved inward, except for a slight sinuation near harp posterior angle. CuP absent. Mirror not differentiated from other cells of D alignment. Cell c1 widened posteriorly, with a faint transverse vein. Apical field almost as long as harp, including one cell alignment (E). Veins R, M and Sc orange, areas between them brown with yellow transverse veins. Lateral field with five or six (n=2) strong parallel longitudinal veins ventral to Sc, with yellow transverse veins.

Male genitalia ( Fig. 17 View FIGURE 17 ): Pseudepiphallus triangular, widened laterally, basal margin curved anteriorly; posterior apex with paired globular lophi, setose. Rami straight and short, slightly divergent. Pseudepiphallic parameres sclerotized, with two large posterior lobes oriented posteriorly, the dorsal the longest; and one basal lobe, membranous. Ectophallic apodemes divergent, long, their bases with expansions forming base of ventral ectophallic membranous lobes. Ectophallic arc complete, wide and straight. Ectophallic fold with lateral sclerites bone-shaped, widened preapically; apex of ectophallic fold narrow and membranous. Endophallic sclerite comprising a short median expansion posteriorly and short lateral arms; sclerite very long anteriorly, exceeding anterior margin of pseudepiphallus. Endophallic apodeme comprising a narrow dorsal crest fused with narrow lateral lamellas.

Female: FWs almost as long as in male, generally slightly overlapping along half of their length, their apex rounded ( Fig. 16B View FIGURE 16 ). FW cells black, not translucent, with strong dark brown to black longitudinal veins and weak yellow transverse ones; with 13–15 (n=3) longitudinal veins, 7–8 on dorsal field, 6–7 on lateral field. Ovipositor slightly shorter than FIII, apex slightly rounded, not denticulate dorsally ( Fig. 9B View FIGURE 9 ). Female copulatory papilla ( Figs. 10G–I View FIGURE 10 ): rounded, convex ventrally; basal sclerite C-shaped, with a triangular basal plate; apex rounded, slightly sclerotized and folded ventrally.

Juvenile: Unknown.
