Diagnosis.
Testaceous to pale olivaceous with dark markings. Labium reaching sixth abdominal sternite (fifth visible). Profemora with ventral and dorsal series of tubercles. Ventral rim of pygophore with shallowly bilobed process. Medial penile plates simple and 3x longer than broad. Eighth gonocoxae of female roughly quadrate with weakly concave posterior margin.
Description.
Body longer than broad (
Fig. 29D
). Head broader than long; juga equal to tylus. Pronotum with anterior margin linear becoming concave medially; anterolateral angle produced laterally as small tubercle; anterolateral margins crenulate, explanate; lateral angles produced into an acute angle; posterior margin slightly concave. Scutellum with lateral margins changing angle but not becoming parallel. Bucculae with anteroventral angle acute, produced anteriorly. Labium reaching sixth abdominal sternite (fifth visible); ratios of labial segments 1:1.9:2:1.2. Peritreme less than 1/2 as long as distance from ostiole of metathoracic scent gland to lateral margin of metapleuron. Episternal ridge located 4/5 of distance between ostiole of metathoracic scent gland and lateral margin of metapleuron. Third through sixth abdominal sternites (second through fifth visible) sulcate. Profemora with ventral row of small stout tubercles; dorsal surface armed with small stout tubercles. Mesofemora with row of small ventral tubercles. Metafemora unarmed.
Color.
Ground color testaceous to pale olivaceous with castaneous markings and punctations. Antennal segments I–II dorsolaterally testaceous; segments III–V with distal half castaneous. Pronotum marked with four dark triangular maculations on the posterior margin. Scutellar bulge of ground color; anterolateral excavations black; median longitudinal ridge straminous with lateral dark maculations. Forewing with mottling of ground color and darker maculations; membrane testaceous. Labium straminous to testaceous, apical portion of labial segment IV castaneous. Legs of ground color; tubercles on profemora castaneous; tarsi mostly straminous, segment III testaceous apically. Venter of abdomen with heavy castaneous speckling around the spiracles’ lateral margins; medial area straminous medially.
Male.
Pygophore constricted around bases of dorsolateral lobes (
Fig. 31A–C
). Ventral rim with median shallowly bilobed process (
Fig. 31A
). Anterior flange of dorsolateral lobes auriculate, posterior margin acute with concavity oriented ectad (
Fig. 31B
); posterior lobes absent; posteroventral lobes acute, directed laterally (
Fig. 31A–C
). Medial penile plates 3X longer than broad (
Fig. 33E
).
Female.
Laterotergites of eighth segment slightly longer than broad, with pair of blunt subtriangular lobes. Gonocoxa of eighth segment large, roughly quadrate with concave posterior margin. Gonocoxa of ninth segment with posterior margin slightly emarginate. Laterotergites of ninth segment acute apically (
Fig. 36E
). Secondary thickening of vagina intima long, 3X longer than broad, slightly bilobed distally, pore to ductus recepticali opening between lobes.
Measurements.
Males (n=5): body length 13.6 SD 0.1 (13.4–13.9), anterior pronotal width 3.7 SD 0.1 (3.6–3.9), humeral width 7.1 SD 0.2 (6.7–7.3), scutellar length 5.2 SD <0.1 (5.2–5.3), medial length of sixth sternite (fifth visible) 0.7 SD <0.1 (0.7–0.8), medial length of seventh sternite (sixth visible) 2.4 SD <0.1 (2.3– 2.5). Females (n=5): body length 15.1 SD 0.1 (14.9–15.4), anterior pronotal width 3.9 SD 0.1 (3.7–4.0), humeral width 7.5 SD 0.1 (7.3–7.6), scutellar length 5.6 SD 0.1 (5.5–5.8), medial length of sixth sternite (fifth visible) 1.2 SD 0.1 (1.1–1.3), medial length of seventh sternite (sixth visible) 1.9 SD <0.1 (1.8–2.0).

Named in honor of the late Dennis Leston, who planned to revise the Australasian
Halyini
and sorted most of the Australasian halyine specimens in The Natural History Museum (London).
