Distribution and habitat ( Fig. 30 ). Drier parts of south-western Western Australia from 35 km north of Galena Bridge on the Murchison River south-east to near Balladonia, with the most inland record being from Mount Linden to the east of Menzies. This distribution falls mostly within a relatively narrow band receiving approximately 350–400 mm mean annual rainfall. Most records are from between Southern Cross and Kalgoorlie but it can be locally common throughout its distribution. Adults have been taken from mid November to late March.

Adult description. Male ( Figs 7a , 31a–d ). Head brown, usually dark brown; irregular black markings surrounding ocelli and around margin of postclypeus, considerably variable in extent between individuals, and a small black spot near back of each eye; ventrally usually a little darker than dorsally and sometimes black including lorum. Postclypeus dark brown, often with the most anterior part and extreme ventral base paler (as in holotype); transverse ridges dark brown or black. Anteclypeus dark brown or black. Rostrum dark brown becoming black distally; reaching bases of hind coxae. Eyes brown in life with a hint of pink. Thorax reddish brown, usually dark reddish brown. Pronotum with a black fascia either side of a light brown dorsal midline, expanded laterally at anterior end and sometimes a little so at posterior end but not reaching pronotal collar; sometimes broken irregular black markings in or near sutures; anterior margin narrowly edged light brown; pronotal collar dark with a black spot on anterior of midline. Mesonotum with submedian and lateral sigilla black to varying degrees, sometimes entirely so on submedian sigilla, less so on lateral sigilla; scutal depressions black, and black at base of cruciform elevation between anterior arms; cruciform elevation usually light brown. Metanotum similar in colour to cruciform elevation. Wings hyaline, without infuscations. Forewing apical cells 3–6 about equal to ulnar cells; basal cell tinted light to dark brown; basal membrane reddish brown. Hindwings with plaga brown, reaching almost to distal end of vein 3A. Legs a mixture of light to dark brown, considerably variable between individuals; fore femora black on outer face adjacent to spines; meracantha black with a narrow pale yellow margin. Opercula light brown on distal half or so, usually black on basal half except for dark brown basal dome but sometimes entirely dark brown on basal half. Abdomen mid to dark brown; tergites sometimes with small, irregular black patches sublaterally; posterior margin of tergite 2 usually edged pale yellow; sternites diffused black along midline variable between individuals. Timbals with four long ribs all similar in length and spanning the full height of the timbal membrane, the three most posterior ribs fused dorsally, and sometimes a fifth anterior rib usually ill-defined; spaced with intermediate short ribs; basal spur small; anterior part of timbal mostly occupied by ribs.

Genitalia ( Figs 31a–d ). See generic description above.

Female ( Fig. 7b ) Similar to male. Abdominal segment 9 dark brown but usually a little paler than other abdominal segments; usually a pair of paramedian black fascia never reaching dorsal spine, sometimes indistinct and occasionally absent; apical spine black; sometimes a black spot mid laterally on distal half. Ovipositor sheath black, projecting beyond apical spine between 2–3 mm.

Measurements. Range and mean (in mm) for 10 males and 8 females (includes largest and smallest specimens). Length of body (including head): male 24.6–27.9 (26.3); female (including ovipositor) 32.0–36.5 (34.2). Length of forewing: male 30.2–33.9 (32.3); female 37.1–39.8 (38.2). Width of head (including eyes): male 7.3–7.9 (7.6); female 8.4–9.1 (8.7). Width of pronotum (across lateral angles): male 7.8–9.1 (8.3); female 9.3–10.6 (9.8).

Distinguishing features. Body colour largely uniform reddish brown that, together with its few markings and long slender body and wings, make this species unlikely to be confused with any other. It differs from all other species by the distinguishing features listed in the generic description above.

Song ( Figs 32a–b ). Recordings were obtained at the WA.GIL and WA.NON paratype locations, from Lake Douglas (30° 50.655’ S 121° 23.077’ E), and from a site ~ 50 km W. of Balladonia . Males produce a calling song during sustained flight in evening dusk conditions. The song is a rapid train of two-pulse syllables, with the pulses of each syllable separated by about 0.01 s and with the syllables produced at 10.0–11.5/sec. In some syllables the pulses appear as doublets, with each having a weak secondary pulse. The song is somewhat high-pitched for the body size, concentrated around 9.5–15.5 kHz with a peak of 11–12 kHz. There is no frequency modulation. A male can be attracted by rapid finger snapping as it passes nearby. One male thus attracted landed on the arm of the responding investigator. Males were not observed to produce sounds while perched on vegetation as in some Yoyetta species that also sing in flight.
