Type locality. Australia, Queensland, Clohesy River road, 16.7 km from Kennedy highway, electricity tower.

Distribution. Australia, Queensland.

Etymology. Species named after its small size.

Diagnosis. J. minoris is characterized by its smaller size, dark brown coloration more homogeneous than in J. rentzi , short stocky FIII, female FW venation reticulated, and following characters in male genitalia: pseudepiphallus wider and shorter than in J. rentzi , convex dorsally in lateral view; pseudepiphallic parameres with a rounded dorsal lobe (more rectangular in J. rentzi ), their bases diverging (parallel in J. rentzi ).

Description. Size small. Coloration mostly dark brown ( Figs 5E–H View FIGURE 5 ). Eyes small, dark brown with a wide pink dorsal band in living specimens ( Fig. 5E View FIGURE 5 ); eyes occupying ca. 35% of head width dorsally. Vertex with five wide longitudinal black bands on orange brown background, the median one resulting from the fusion more or less complete of two bands ( Fig. 6D View FIGURE 6 ). Fastigium orange brown twice as wide as scape, densely setose. Ocelli whitish. Scapes orange brown, with a black pattern on facial side; antennae light brown basally, then darker with yellow brown rings. Frons dark brown, with two black dorsal spots. Face dark brown, with a yellow spot bellow eyes. Lateral side of head dark brown, with two faint yellow lines posterior to eyes. Mouthparts homogeneously dark brown in HT, but some specimens with similar pattern of coloration as in J. rentzi : clypeus with two lateral yellow spots on dorsal margin and a faint trident-shaped whitish pattern on ventral part ( Fig. 6B View FIGURE 6 ); mandibles black basally, yellow ventrally; labrum brown; Maxillary palpi brown. Pronotum: Dorsal disk homogeneously brown; lateral lobes homogeneously black. Wings brachypterous, very short in both sexes. Legs orange brown; FI-II with dark brown spots, TI-II with a faint lighter ring; tarsomeres yellow basally. FIII short and stocky, mostly orange brown, knees dark brown, mottled with white spots and with dark striated patterns. TaII-1 with one lateral spine on lateral external side in HT and 1 PT. Abdomen dark brown; cerci orange brown mottled with dark brown basally, with dark rings apically.

Male: FW dorsal field ( Fig. 7C View FIGURE 7 ) translucent brown with yellow veins, its antero-lateral corner with a large whitish sclerotization; area of plectrum with a strong orange sclerotization. Vein 1A bisinuate anterior to angle. File with 116 stridulatory teeth distributed on transverse part of 1A (107) and on angle (9) (n=1). CuA barely curved inward. CuP absent. Mirror not rounded but well differentiated from other cells of D alignment, forming a wide rectangle. Cell c1 not widened posteriorly, without transverse vein. Apical field short, with faint reticulated veins posterior to mirror (cell alignment E). Lateral field homogeneously dark brown (veins and cells); veins R and M strong, delimiting a darker area; Sc with one preapical projection. Lateral field with five (n=1) strong parallel longitudinal veins ventral to Sc, with faint dark transverse veins.

Male genitalia ( Fig. 13 View FIGURE 13 ): Pseudepiphallus triangular, less elongate than in J. rentzi ; convex dorsally in lateral view; posterior apex forming a gutter barely longer than wide ( Fig. 13A View FIGURE 13 ). Pseudepiphallic parameres dorsal posterior lobe rounded, their bases diverging.

Female: FWs very short, separated dorsally by half their length, apex rounded; its venation mostly reticulated. Ovipositor slightly shorter than FIII, apex acute, slightly denticulate dorsally. Female copulatory papilla ( Figs. 10D–F View FIGURE 10 ): rounded, flat ventrally; apex slightly sclerotized and folded ventrally.

Juvenile: Brown, with similar color pattern as in adults.

Measurements. See Table 2.

Habitat and life history traits. J. minoris was found active at night on low plants in forested areas.

Calling song. Unknown.
