Anal styles orange-red; ovipositor sheath dark brown to black.

Measurements (in mm; range with mean in parentheses: 10 males, 8 females). Body length: male 25.0–25.1 (25.1); female 24.0–27.0 (26.0). Fore wing length: male 27.7– 28.5 (28.1); female 29.4–33.2 (31.9). Head width: male 7.0–7.6 (7.3); female 6.8–7.6 (7.4). Pronotum width: male 6.7–7.4 (7.1); female 6.5–8.4 (7.5). Abdomen width: male 7.4–8.0 (7.7); female 7.5–8.2 (7.8). Ovipositor length 7.6–8.4 (8.0).

Etymology. Since most specimens have been collected in cool temperate areas, the species name reflects the climatic situation where this species is typically found.

Distinguishing features. Yoyetta subalpina sp. nov. displays concentric orange bands on the posterior margins of tergites 3–7; these are absent on Y. denisoni , Y. kershawi stat. rev., comb. nov., Y. timothyi sp. nov. and Y. grandis sp. nov. It is readily distinguished from Y. abdominalis , Y. electrica sp. nov., Y. spectabilis sp. nov. and Y. serrata sp. nov. by the following combination of characters: (1) large size with body length> 23 mm, (2) lack of symmetrical, orange triangular patterns on tergites 4–7, (3) ovipositors of females extend> 1 mm beyond the posterior abdomen. The forewing basal membranes of Y. regalis sp. nov. and Y. subalpina sp. nov. are bright orange contrasting with the grey basal membranes of Y. grandis sp. nov. in southern Victoria and the dull orange basal membranes of specimens of Y. grandis sp. nov. in the Grampians Ranges. Morphologically, male specimens of Y. subalpina sp. nov., Y. verrens sp. nov. and Y. regalis sp. nov. are difficult to differentiate, but the follow features can be used to achieve the correct identification. In Y. subalpina sp. nov., the white colouration on the hind wing plaga is bold and extends to cover the entire jugum (cf. in Y. verrens sp. nov. the colouration is dull white and restricted along the margins of anal cell 3 and vein 2A). In Y. subalpina sp. nov., the sternites are predominantly orange, sometimes with diffuse black spots medially (cf. in Y. regalis sp. nov. where the sternites have bold black medial markings that occupy more than half of each sternite). In female specimens, there is substantial colour variation morphologically (orangebrown to black) within species, but the ovipositors extend beyond the abdomen around 1.0 mm for Y. subalpina sp. nov., 1–1.5 mm for Y. regalis sp. nov.,> 1.5 mm for Y. grandis sp. nov., and> 2 mm for Y. verrens sp. nov. The length of the ovipositor of Y. regalis sp. nov. is> 8.8 mm, <8.6 mm for Y. subalpina sp. nov., and> 10.0 mm for Y. grandis sp. nov.

Calling song ( Figs 29–31 View Figure 29 View Figure 30 View Figure 31 , 53G View Figure 53 ). The male calling song of Y. subalpina sp. nov. is a simple repetition of phrases, each

comprising an echeme followed by a macrosyllable ( Fig. 29A View Figure 29 ). Closer inspection of the echeme ( Fig. 29B View Figure 29 ) reveals that it comprises a series of macrosyllables that increase in amplitude and coalesce at the highest point of amplification, typically occurring between 0.16 and 0.43 s duration (n = 13). A short gap of 0.01– 0.04 s duration separates the echeme from the proceeding macrosyllable. The macrosyllable is typically louder than the echeme. It lasts between 0.05 and 0.09 s ( Fig. 29C View Figure 29 ). Gaps of approximately 0.5 s duration separate each phrase. After warming up a little, males sometimes produce soft ticking (syllable trains) in the gaps between each phrase, with longer syllable trains between bouts of phrases ( Fig. 30 View Figure 30 ).

Males from most locations across the geographical distribution of this species had a frequency plateau of 8.4–11.1 kHz and a dominant frequency ranging between 9.4 and 10.1 kHz ( Fig. 31 View Figure 31 ). The exceptions were males from Talleganda that produced a slightly lower frequency plateau, ranging from 7.1–9.7 kHz with a dominant frequency of 8.4–9.0 kHz (n = 4; Fig. 30 View Figure 30 ).

Within the Y. abdominalis species group, the calling song of Y. subalpina sp. nov. is most similar to Y. verrens sp. nov. The main difference in the call of Y. subalpina sp. nov. is the addition of a macrosyllable following the echeme, which gives it a distinct two-note signature (cf. the single echeme sweeping notes of Y. verrens sp. nov.).
