Distribution, habitat and seasonality. Highland locations from Barrington Tops south to the Southern Highlands of New South Wales. Specimens have been found in coastal locations from northern Sydney, south to eastern Victoria, close the Melbourne ( Fig. 18 View Figure 18 ). Adults occur mainly on small heath shrubs and sometimes on eucalypts. Males constantly

move between singing stations that are usually <3 m high. Females are located close to ground level. Since their song is somewhat similar to that of Y. regalis   sp. nov., the location of Y. spectabilis   sp. nov. on the heathland shrubs contrasts with the distinct preference of the former species for smooth-barked eucalypts when the two species cohabit open woodland. This species can be encountered from late November to January.


Male ( Figs 2D View Figure 2 , 3D View Figure 3 , 22A,B,F View Figure 22 , 52D). Head almost as wide as mesonotum, black in mountain specimens, with a small, triangular brown fascia posterior to ocelli, reducing anteriorly, and a small to large ochraceous spot on posterior margin between ocelli and eye; covered with black pubescence. In coastal specimens, including the holotype, pale brown to ochraceous posteriorly, extending halfway around eye, black surrounding ocelli, black spot medial to eye; ocelli pink; postclypeus dorsally dark brown to black with yellowish triangular median fascia, apex directed anteriorly, ventral surface black with black transverse grooves, midline with ochraceous line over anterior half in some specimens, lateral and posterior borders ochraceous, tending reddish; anteclypeus black, rostrum black at base, dark brown centrally, black at apex, reaching anterior edge of hind coxae; lora ochraceous anteriorly, variably black on medial and posterior sections; eyes variably dull black to dark brown; antennae black, supraantennal plates black, coastal specimens with central brown spot on anterior margin extending laterally above pedicel.

Thorax predominantly dull black on mountain specimens, brown on coastal cicadas. Pronotum black with distinct ochraceous marking over central third of midline, variably bordered by black, fissures variably black, tending brown on raised areas; pronotal collar brown centrally, variably tending black laterally, lateral angles black, paranota black on posterior and lateral margins, becoming brown elsewhere. Mesonotum black on mountain cicadas, coastal specimens brown with sigilla, scutal depressions and surrounds black; cruciform elevation arms black, lateral depressions brown. Metanotum black.

Abdomen. Tergite 1 black with red lateral membranes; tergites 2–3 black with diffuse dark brown shading on some coastal specimens, intersegmental membranes orange; tergites 4–7 black with thin orange posterior margins, an increasing area of lateral orange coloration posteriorly forming a triangular shape with base on tergite 7, extending to lateral border and to epipleurite 7; tergite 8 shiny black, with orange-red posteriorly and extending laterally in some specimens. Epipleurites with variable black medial markings, fiery red laterally and posteriorly. Sternite II mainly black; sternite III black centrally, orange-red laterally; sternites IV–VI orange, posterior halves becoming red, black midline markings over anterior two-thirds of each sternite, decreasing posteriorly, sternite VIII fiery red, with yellowish pubescence ( Fig. 51D View Figure 51 ).

Genitalia ( Fig. 23 View Figure 23 ). Pygofer black, dorsal beak black, anal styles bright red; upper lobe black; basal lobe black. Uncus reddish-brown, orange-brown laterally; in lateral view beak-like; lobes in ventral view narrow, with rounded lateral termination; claspers clearly divided, short, with apices tapering laterally. Aedeagus with pseudoparameres extending around three-quarters the length of theca; theca recurved ventrally around 180° towards apex, with transparent flange along dorsal margin of distal half of recurvature, broadly smooth, equal to width of theca; apex short, knob-like, with 6–8 prominent cornuti.

Female ( Fig. 22 View Figure 22 C–E). Head and thorax similar to male, and with patterns of black and brown markings within the range described for coastal and mountain male specimens.

Abdomen similar to coastal and mountain male specimens for the range of markings on tergites and sternites; sternites III–VII becoming more orange-red posteriorly, with midline black marking also reducing progressively from sternite III to sternite VII; abdominal segment 9 black dorsally with orange longitudinal stripes either side of midline, curving anteriorly and becoming orange to red laterally and ventrally; dorsal beak black. Ovipositor brown, black at tip, not extending beyond apex of abdominal segment 9. Anal styles bright red; ovipositor sheath dark brown to black.

Measurements (in mm; range with mean in parentheses: 12 males, 12 females). Body length: male 19.6–22.7 (21.0); female 21.4–26.5 (22.6). Fore wing length: male 23.4–26.7 (24.8); female 26.3–28.4 (26.9). Head width: male 6.0–6.8 (6.5); female 6.9–7.3 (7.1). Pronotum width: male 6.0–6.7 (6.3); female 6.3–7.3 (6.8). Abdomen width: male 5.8–6.5 (6.4); female 6.0–7.3 (6.7). Ovipositor length 6.1– 6.8 (6.5).

Etymology. “ Spectabilis ” (Latin) depicts the impressive coloration and markings that range from orange-red to enamel black in this species.

Distinguishing features. Yoyetta spectabilis   sp. nov. is readily distinguished from Y. denisoni   , Y. timothyi   sp.

nov., Y. kershawi   stat. rev., comb. nov., Y. regalis   sp. nov., Y. grandis   sp. nov., Y. subalpina   sp. nov., Y. grandis   sp. nov. and Y. verrens   sp. nov. by the following combination of characters: (1) smaller size with body length <23 mm, (2) presence of symmetrical, orange triangular patterns on tergites 4–7, and (3) ovipositor sheaths of females not extending beyond the apex of abdominal segment 9. It differs from Y. hunterorum   , which has the opercula and sternite 8 dull brown, the female abdominal segment 9 without red markings and the female ovipositor sheath extending> 1.5 mm beyond the apex of the abdomen. The orange triangular patterning on the tergites of Y. spectabilis   sp. nov. is distinct from the annular banding on Y. electrica   sp. nov. which is also smaller (BL <18 mm).

Specimens of Y. spectabilis   sp. nov. can be difficult to distinguish from Y. serrata   sp. nov. and some specimens of Y. abdominalis   , which have a similar range of shapes, sizes and markings. While the calling songs are quite distinctive, Y. spectabilis   sp. nov. can also be distinguished from Y. abdominalis   and Y. serrata   sp. nov. by the following combination of characters: (1) lack of longitudinal central fascia on the pronotum in male specimens; (2), the colouration of the male opercula, which is predominantly red (cf. dull reddish-brown in Y. serrata   sp. nov. and black to pale brown in Y. abdominalis   ); (3), the forewing costa and basal membrane is bright orange-red; (4) epipleurites boldly red and black.

Calling song ( Figs 24 View Figure 24 , 25 View Figure 25 , 53K View Figure 53 ). The male calling song of Y. spectabilis   sp. nov. consists of a series of “whirling” amplitude modulations and produced at rest. Close examination reveals that these are organized into long echemes. The calling song commences with an introductory echeme with rapidly-emitted and regular amplitude modulations (“round whirling”; Fig. 24 View Figure 24 A–C). Towards the end of the echeme, the rate of modulation decreases, with each modulation commencing abruptly and fading (“abrupt whirling”; Fig. 24A,D,E View Figure 24 ). Each echeme ends with a sharp terminal modulation equivalent to a macrosyllable ( Fig. 24F View Figure 24 ). The first echeme is the longest, lasting about 5–8 s. The second echeme sometimes has the same form, though with a shorter round whirling section. The typical echemes following these introductory echeme(s) are simplified, losing the round whirling altogether and only exhibiting the abrupt whirling and sharp terminal modulation. A comparison between the typical echemes recorded at multiple sites in provided in Fig. 24 View Figure 24 . These typical echemes are around 2 s duration.

The highest frequency plateau for the 513 calling song ranges between 8.9–13.0 kHz, with a dominant frequency between 9.5–12.1 kHz ( Fig. 24 View Figure 24 ).

Within the genus Yoyetta   , the calling song of Y. spectabilis   sp. nov. most closely resembles that of Y. regalis   sp. nov. The song of Y. spectabilis   sp. nov. differs most noticeably in the slower modulation rate and the presence of both round whirling and abrupt whirling types of amplitude modulation (cf. one type of rapidly emitted amplitude modulation in Y. regalis   sp. nov.). Yoyetta spectabilis   sp. nov. also does not produce intervening short chirps between bouts of echemes, which is a feature of the song of Y. regalis   sp. nov.
