Etymology. The name is derived from the Latin word for Lion (presented as a noun in apposition). This refers to the striking modulation in amplitude during each phrase of the calling song. In the output of a bat detector, this modulation resembles the roar of a lion.

Opercula ( Fig. 1F View FIGURE 1 ): Broadly rounded; typically dark brown to brown throughout, sometimes darker basally; plates undulating, medial areas weakly depressed.

Timbals ( Fig. 2F View FIGURE 2 ): Anterior rib 5 abbreviated; rib 4 also abbreviated, with a prominent isolated remnant extension ventrally; ribs 1 and 2 joined ventrally and fused dorsally to basal spur; anterior termination of basal spur fused with ribs 3–4, with rib 5 unattached; prominent intercalary short ribs in medial areas between ribs 1 and 2, 2 and 3, and 3 and 4 (three in total).

Abdomen: Tergite 1 black; tergite 2 wider along dorsal midline than tergites 3 to 7; tergites 2 to 7 black, with brown areas on dorso-lateral posterior halves extending to posterior margins, all with dense short silver pubescence on dorso-lateral sides and with extensive long and short silver pubescence on lateral sides; tergite 8 black, dark dark brown on posterior half of lateral sides, covered in short silver pubescence; intersegmental membranes pale brown; epipleurites dark brown, with sparse silver pubescence; sternite II black laterally, pale brown to pale reddish-brown ventro-laterally, with a dark brown area medially; sternites III to VI pale brown to pale reddishbrown laterally, with dark brown areas medially, which broaden posteriorly, gradually increasing in size distally in each successive sternite; sternite VII dark brown to black, sometimes with diffuse brown to reddish-brown areas at extreme anterio-lateral margins; sternite VIII dark brown to black; anterior sternites visible in lateral view.

Genitalia ( Figs 3K, L View FIGURE 3 ): Pygofer brown to dark brown; upper lobes in ventral view relatively linear, with terminals directed dorsally and apically acute; basal lobes in ventral view relatively linear, in lateral view gradually curved, subtly expressed; median lobe of uncus rounded, protruding; claspers in ventral view conspicuous, diverging markedly from point of downward deflection, with sharply developed apices; pseudoparameres projecting further (ventrally) than endotheca and ventral support; ventral support acute, projecting slightly beyond endotheca; endotheca fleshy.

Female ( Plate 6C View PLATE 6 ): Head, thorax, wings and legs match description of male.

Abdomen: Tergite 1 black; tergites 2 to 8 black, with broad brown to orange-brown areas on posterior dorsolateral and submedial sides, being most extensive on tergite 2; auditory capsules black; abdominal segment 9 dark brown to black, brown to orange brown on posterior third of dorso-lateral sides, dirty pale brown ventrally; dorsal beak black, sharply defined; sternite II pale brown to pale reddish-brown, black laterally and medially; epipleurites dark brown to black; sternites III to VI pale brown to pale reddish-brown with broad black areas medially, broadening posteriorly, typically similar in width, though often widest on sternite IV; sternite VII pale brown to pale reddish-brown with short, oblique, darker longitudinal markings medially; ovipositor sheath extends approximately 2.5–3.0 mm beyond termination of abdominal segment 9.

Morphological distinguishing features. Myopsalta leona   n. sp. can be distinguished from M. atrata   , M.

binotata   , M. coolahensis   , M. gordoni   n. sp., M. lactea   , M. libritor   , M. waterhousei   and M. xerograsidia   n. sp. by the colour of the basal membranes of the fore wings, which is pale brown or pale orange rather than white to pale grey. It can be distinguished from M. melanobasis   n. sp. and M. platyptera   n. sp. by the appearance of the distal corner of the fore wing basal cell (adjacent to the costa and radial cell), which is entirely hyaline and not partly translucent. Males and females can be separated from M. albiventris   n. sp. and M. wollomombii   by the colouration of the sternites, which is predominantly dark brown (cf. almost entirely pale brown). They can be differentiated from M. umbra   n. sp. by the colour of the costal veins, which is brown rather than reddish-brown. Males can be distinguished from M. septa   n. sp. and M. crucifera   by the colouration of sternite VII, which is entirely dark brown to black (not bordered with pale brown on any margin). They can be distinguished from M. chrysopedia   n. sp., M. longicauda   n. sp. and M. majurae   n. sp. by having a head width of ≤ 4.6 mm, from M. parvula   n. sp. by having broad, contrasting, pale reddish-brown lateral edges on sternite III (cf. almost entirely dark brown to black), from M. bassiana   n. sp. by having fore wings ≤6.0 mm in width, and from M. riverina   n. sp. by the short length of the rostrum, which does not extend beyond the mid coxae. They can be separated from the closely similar M. mackinlayi   by the colouration of the opercula, which is dark brown to black rather than predominantly pale brown. In addition, they can be separated from by the presence of contrasting pale brown colouration on the ventro-lateral sides of sternite II. Females can be distinguished from M. bassiana   n. sp., M. mackinlayi   , M. longicauda   n. sp., M. parvula   n. sp., M. septa   n. sp. and M. umbra   n. sp. by the length of the ovipositor sheath, which extends approximately 2.5–3.0 mm beyond the apex of abdominal segment 9; this length being approximately equal to the length of abdominal segment 9 (in other species the sheath extension is noticeably longer or shorter than the abdominal segment). They can be differentiated from the superficially similar M. crucifera   by the colouration of the thorax and dorsal abdomen, which is dark brown or brown (cf. pale brown in M. crucifera   ). Finally, they can be separated from M. chrysopedia   n. sp. by their smaller size (head width <4.7 mm).

Distribution, habitat and behaviour ( Fig. 11 View FIGURE 11 ). Myopsalta leona   is found south from the tropic of Capricorn in western, southern central and inland south-eastern Queensland from the eastern edge of the Simpson Desert south-east to the Lockyer Valley west of Brisbane. It also occurs in inland New South Wales from Narrabri west to Lightning Ridge and south to Goolgowi. Populations occur in acacia-dominated woodland and shrubland, as well as dry, temperate eucalypt woodland where the adults are typically found on the branches and in the foliage of trees and larger shrubs. Adults have been encountered from October to March. They have occasionally been observed in very large numbers, spreading from vegetation on to nearby wooden power poles and fence posts.

Calling song ( Figs 13 View FIGURE 13 , 14 View FIGURE 14 ). The song of this species contains repetitive buzzing phrases, each with a brief inflection in amplitude and frequency towards the middle. Each phrase commences with a long echeme, typically with a duration of 2.018– 3.954 s, followed by a brief gap (0.004– 0.021 s) and a syllable or macrosyllable of 0.011– 0.029 s duration (all statistics, n= 17 recordings). Close inspection of the structure within the long echeme sometimes reveals that the beginning contains a series of discrete syllables, or alternatively it may be entirely coalesced. The inflection occurs in the long echeme, typically half way to two thirds into its overall duration. The highest point of inflection can reach up to four times the amplitude of the beginning of the echeme and may be sustained at this increased volume for up to 0.6 s. Observations indicate that the inflection is cause by a marked upward contraction of the abdomen, followed by partial relaxation. Generally, the amplitude remains slightly higher relative to the beginning of the echeme for the remainder of the echeme following the inflection.

Prior and following to the inflection, the calling song typically exhibits a highest amplitude frequency plateau between 11.2 and 18.4 kHz. This increases to 13.0–19.5 kHz, or slightly higher, during the inflection. Some geographic variation is evident in calling song, with larger specimens from central New South Wales exhibiting slightly extended long echeme (up to 5.91 s) and lower frequency plateaus (8.7–15.2 kHz before inflection and 11.4–17.0 kHz at inflection). In addition, in recordings from Cravens Peak at the western edge of the species’ distribution, produce slightly shorter long echemes (1.417– 1.510 s) and the inflection is produced earlier than in other examples ( Fig. 14A View FIGURE 14 ).
