Distribution ( Fig. 22 View Figure 22 ). Known only from Herveys Range, west of Townsville, Queensland. The three known specimens were taken on 10th January.
Habitat. Dry open eucalypt forest where adults prefer the upper branches of trees of medium height.
Male (Pl. 4). Head wider than lateral margins of pronotal collar but narrower than lateral angles; dominantly black with yellowish brown spot at posterior midline. Postclypeus black with yellowish brown markings; usually a partly yellowish brown dorsally; a yellowish brown mark on midline around most anterior portion; lateral, and usually posterior, margins yellowish brown; transverse ridges and central groove distinct. Anteclypeus black. Rostrum black, tending brown proximally, reaching to beyond apices of hind coxae. Antennae brown. Supra-antennal plates black, edged yellowish brown along anterior margin to varying degrees.
Thorax. Pronotum black with yellowish brown markings; fascia along midline yellowish brown, usually extending from or near head towards or almost to pronotal collar; a yellowish brown marking on either side of midline dorsally, abutting and/or on anterior margin of pronotal collar; pronotal collar yellowish brown; lateral angles sometimes black to varying degrees; lateral margin not, or barely, ampliate. Mesonotum primarily black with yellowish brown or reddish brown markings; usually a yellowish brown or reddish brown marking on either side from, or near, anterior arms or the cruciform elevation to, or almost to, pronotum between lateral and submedian sigilla, this marking projecting inwards to varying degrees around its mid length sometimes meeting and sometimes extending along midline, and sometimes surrounding scutal depressions; lateral margins usually yellowish brown; cruciform elevation yellowish brown and black, sometimes muddy brown, anterior arms usually yellowish brown, posterior arms usually brown, sometimes proximally black, black between anterior and posterior arms, often a black fascia down midline. Metanotum black at hind wing base, remainder reddish brown, sometimes black at dorsal midline.
Legs. Fore legs mostly black but with a brown to reddish brown fascia to varying degrees along anterior and exterior length of femora, sometimes a brownish red fascia along lateral interior of femora; femora with spines black; tarsi usually with one yellowish brown patches; pretarsal claws yellowish brown tending black distally. Mid and hind legs mostly black or brown tending dark brown; coxae with proximal margin edged brown; yellowish brown fascia along anterior, interior, exterior length of femora; tibiae brown tending black distally; tarsi sometimes with one yellowish brown patches. Meracanthus black with outer lateral margin and apex pale yellow.
Wings. Hyaline. Fore wing with fused stem of veins M and CuA not complete, the veins abutted rather than fused as one; venation brown; basal membrane muddy brown. Hind wing with 5 apical cells; venation brown except for pale yellowish brown 2A and 3A; plaga muddy white to brown; black infuscation on wing margin at distal end of vein 2A.
Opercula. For the most part not reaching distal margin of tympanal cavity; widely separated; a low rounded swelling of epimeron 3; black, sometimes yellowish brown on distal half.
Timbals with four long ribs spanning the width of timbal membrane and one much shorter anterior rib terminating level with upper end of adjacent intercalary rib.
Abdomen. Tending triangular in cross section with epipleurites reflexed inwards from junction with tergites. Tergites black with reddish brown and yellow markings. Tergite 1 black; tergites 2–8 black with posterior margin reddish brown to varying degrees, sometimes a reddish brown spot adjacent to posterior margin on dorsal midline, extreme posterior margin usually narrowly edged orange. Sternite I brownish black with muddy yellow dorsally; sternites II mostly black or nearly so; sternites III–VII orange, sometimes with posterior margin yellowish orange to varying degrees; sternite VIII yellowish brown.
Genitalia ( Fig. 22 View Figure 22 ). Pygofer upper lobe narrow and long, in lateral view gradually tapering to a rounded apex, apex slightly down-curved. Basal lobe well developed, distally rounded in ventral view, flat, not turned inwards. Secondary basal pygofer lobe small, in lateral view rounded. Basal lobe rounded in lateral view, flat, not turned inwards. Median lobe of uncus tending triangular with a narrow rounded apex. Claspers claw-like, flattened and narrow in dorsal view, distally slightly diverging, concave below. Aedeagus with pseudoparameres inconspicuous, translucent, hair-like, lying adjacent to dorsal surface of endotheca, arising at about one quarter length of endotheca and terminating at about three quarters its length. Endotheca long, parallel sided, circular in cross-section; apex divided into a pair of similar flat lobes, lateral view these paddle-like with apices pointed, in dorsal view diverging more or less in a Y-shape.
Measurements. Range and mean (in mm) for 3♂♂; includes smallest and largest of available specimens. Length of body: 21.3–22.8 (22.1). Length of fore wing: 27.6–28.7 (28.3). Width of fore wing: 9.0–9.8 (9.4). Ratio length/width of fore wing:
2.9–3.1 (3.0). Width of head (including eyes): 6.9–7.5 (7.2). Width of pronotum (across lateral angles): 7.3–8.2 (7.7).
Distinguished from most other species of Pauropsalta in having the stems of fore wing veins M and CuA closely abutted rather than fused as one. Amongst those species with abutted veins care should be taken not to confuse this species with Pau. opaca or Pau. ewarti . Distinguished from Pau. ewarti by the length of the rostrum; that of Pau. herveyensis reaches or almost reaches the apices of the hind coxae while that of Pau. ewarti barely reaches the bases of the hind coxae. Distinguished from Pau. opaca in having the inner areas of the pronotum entirely black whereas Pau. herveyensis has much of the inner pronotum pigmented with dark reddish brown patches.
Male genitalia are unique in having an aedeagus with pseudoparameres that are very small, hair-like, translucent and almost indiscernible, and an endotheca that has its apex divided into a pair of paddle-like lobes narrowed apically.
Etymology. Named after Hervey’s Range where the only specimens have been collected.
Song ( Fig. 22 View Figure 22 ). The song is composed of a series of phrases each with a series of clicks followed by an echeme. The number of clicks ranges from 17–26. Echemes range in length from 1–3 s. The length of each phrase usually ranges from 9–11 s. The frequency of the song ranges from 3–18 kHz.
