Olonia picea  – Kershaw & Muir 1922: 208 (note on male genitalia). — Muir 1923: 231, pl. 5, fig. 12 (male genitalia described and illustrated). — Jacobi 1928 (synonymized with O. transversa  (erroneous)). — Metcalf 1956: 66 (catalogued, as O. transversa  (erroneous)). — Constant 2005b: 66 (removed from synonymy with O. transversa  ).

Diagnosis

This species can be recognized by the following combination of characters:

(1) hind wings without orange marking ( Figs 41EView Fig. 41, 43EView Fig. 43)

(2) pro- and mesofemora and tibiae largely black-brown ( Figs 41A–DView Fig. 41, 43A–DView Fig. 43)

(3) anal tube of male obovate, narrowing at basal ½ ( Fig. 42BView Fig. 42)

(4) centroventral part of gonostyli with strong, elongate process curved laterally and pointed apically ( Fig. 42A, CView Fig. 42)

(5) laterodorsal part of gonostyli strongly bifid, with dorsal and ventral process forming a C together ( Fig. 42A, C–DView Fig. 42)

(6) rather small size: 6.5–7.5 mm

Females of O. picea  are nearly impossible to separate from females of the sympatric O. maura  and should be identified only if collected together with males.

Etymology

The species epithet piceus (adjective, Latin) means ʻpiceousʼ, ʻbrownʼ. It refers to the general colour of the species.

Description

MEASUREMENTS AND RATIOS. LT: ♁ (n = 6): 7.2 mm (6.8–7.4); ♀ (n = 1): 7.2 mm; Ltg/BTg (♁) = 2.3.

Male

HEAD ( Fig. 41A–DView Fig. 41). Vertex slightly concave, with anterior and posterior margins parallel, curved; medium to dark brown; obsolete median carina shortly marked along posterior margin. Frons uniformly coloured, medium to dark brown, sometimes darker at lateral angles. Clypeus elongate, entirely medium to dark brown. Genae brown to black with yellowish markings along anterior margin. Labium brown

to black, reaching metacoxae. Antennae black-brown; scape short, ring-shaped; pedicel subcylindrical, slightly narrowing towards apex.

THORAX ( Fig. 41A–DView Fig. 41). Pronotum uniformly medium to dark brown; slightly wrinkled; 2 small impressed points on disc slightly marked. Lateral fields of prothorax coloured as pronotum. Mesonotum medium to dark brown variegated with darker zones on middle and sides; minute yellowish spot at apex of scutellum; median and peridiscal carinae weakly marked; median carina ending before scutellum; slight impression before scutellum. Red ventrally. Tegulae medium to dark brown.

TEGMINA ( Fig. 41A, CView Fig. 41). Medium to dark brown; often pale yellowish marking on vein A1 at midlength of clavus; marked with dark brown or black along costal margin, more broadly so on posterior half, and along posterior margin. Often darker, median, irregular marking at apical ¾; triangular white marking on costal margin on nodal line, sometimes reduced; sometimes a number of minute white spots at

apicosutural angle. Costal and sutural margins subparallel; costal margin slightly sinuate; apical margin obliquely rounded.

POSTERIOR WINGS ( Fig. 41EView Fig. 41). Brown, paler on anal area and progressively darker on apical half; small, somewhat rounded white marking at apicocostal angle, extending on 2–3 cells. Margin of anal area slightly sinuate; sutural margin with 1 slight cleft, cubital one nearly not marked.

LEGS ( Fig. 41A–DView Fig. 41). Pro- and mesocoxae black-brown. Pro- and mesofemora black-brown variegated with brown. Pro- and mesotibiae medium to dark brown, sometimes with 3 paler obsolete rings. Pro- and mesotarsi black-brown, with basal half of third tarsomere paler. Metacoxae reddish; metafemora reddish with apex brown. Metatibiae brown, with 3 lateral spines paler basally and 9 apical black-brown spines. Metatarsi brown, with a ventral row of 6 black spines on first tarsomere.

ABDOMEN. Bright red with genital segments black-brown.

MALE GENITALIA ( Fig. 42View Fig. 42). Posterior margin of pygofer in lateral view strongly sinuate, strongly roundly projecting at dorsal ½, moderately broad ventrally ( Fig. 42A, CView Fig. 42). Anal tube obovate, 1.9 times as long as broad, narrowing at level of epiproct, slightly curved ventrally in lateral view; lateral margins slightly curved ventrally on apical half; apical margin roundly pointed ( Fig. 42A–BView Fig. 42). Gonostyli fused on basal half of length of centroventral part and projecting posteriorly ( Fig. 42A, CView Fig. 42). Centroventral part broad and dorsoventrally flattened on basal half, then narrowing into an elongate, curved, spinose process directed laterally and ending in ventrally curved point ( Fig. 42A, CView Fig. 42). Laterodorsal part of gonostyli strong and curved dorsocentrally, slightly surpassing level of centroventral part ventrally, bifid, with a dorsal and a ventral process elongate and pointing apically, and forming a C together; lateral process elongate, projecting posterolaterally and longer than spoon-shaped process ( Fig. 42A, C–DView Fig. 42). Dorsal portion of phallobase with hooked process on each side, progressively narrowing from base to apex, directed posterodorsally and with apex pointing centrally ( Fig. 42E–FView Fig. 42). Ventral portion of phallobase subquadrate, with apical margin emarginate in dorsal view and with median lobe not surpassing phallus ( Fig. 42E–FView Fig. 42). Phallus dorsoventrally flattened, rather broad, with apical margin emarginate in middle ( Fig. 42E–FView Fig. 42).

Female

Similar to male but with white spot on costal margin of tegmina at nodal line reduced, and sometimes with white, transverse marking on costal margin of tegmina slightly before half length and extending to vein RP ( Fig. 43View Fig. 43).

Distribution and biology

This species has been recorded from an area around Cairns in North Queensland ( Fig. 3View Fig. 3), in the Einasleigh Upland Savanna and Queensland Tropical Rainforests bioregions. Specimens were collected in January, February, March, April, July, August and September. No host plant known.
