Diagnosis

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

(1) hind wings without orange marking ( Figs 32E View Fig , 34E View Fig. 34 ) and with apical margin bordered with white in females ( Fig. 34E View Fig. 34 )

(2) pro- and mesofemora and -tibiae largely black-brown ( Figs 32A–D View Fig , 34A–D View Fig. 34 )

(3) anal tube of male obovate after epiproct and with posterior margin truncate ( Fig. 33B View Fig )

(4) centroventral part of gonostyli with strong pointed processes curved laterally ( Fig. 33A, C View Fig )

(5) laterodorsal part of gonostyli bifid, with dorsal process shorter than ventral one and both directed posteriorly ( Fig. 33A, C–D View Fig )

(6) medium size: 8.3–9.7 mm

Etymology

This species is dedicated to Dr Geoff Monteith, who collected the type specimens.

Male

HEAD ( Fig. 32A–D View Fig ). Vertex concave, with anterior and posterior margins parallel, curved; black-brown slightly variegated with brown. Frons black-brown slightly wrinkled and with paler markings along dorsal margin. Clypeus elongate, black-brown, tinged with reddish in middle and with small reddish point at basolateral angles. Genae brown-black with yellowish markings around eyes and along anterior margin. Labium black-brown, reaching metacoxae. Antennae black-brown; scape short, ring-shaped; pedicel subcylindrical, slightly narrowing towards apex.

THORAX ( Fig. 32A–C View Fig ). Pronotum black-brown slightly variegated with yellowish along anterior margin and with small yellowish spot at lateral angles; slightly transversely wrinkled posteriorly; obsolete median carina and 2 small impressed points on disc. Lateral fields of prothorax black-brown. Mesonotum blackbrown, slightly wrinkled, with apex of scutellum slightly reddish; median and peridiscal carinae weakly marked; median carina stopping before scutellum; slight impression before scutellum. Red ventrally. Tegulae black-brown.

TEGMINA ( Fig. 32A, C View Fig ). Black-brown with median area paler; small reddish spots on basal half and clavus; large white transverse marking along costal margin at half length, with additional smaller white spots in a row; large triangular white marking on costal margin on nodal line, nearly extending to white spots at apicosutural angle. Maximum breadth at basal ½; costal margin sinuate; apical margin obliquely rounded.

POSTERIOR WINGS ( Fig. 32E View Fig ). Brown with apical half turning to black and anal area paler; transverse, broad, subtriangular white marking at apicocostal angle, extending on 7–8 cells. Margin of anal area slightly sinuate; sutural margin with 2 clefts, cubital one slightly marked.

LEGS ( Fig. 32A–D View Fig ). Pro- and mesocoxae black-brown. Pro- and mesofemora black-brown with 2 obsolete yellowish rings. Pro- and mesotibiae black-brown with 3 obsolete yellowish rings, larger one near apex. Pro- and mesotarsi dark brown with basal half of third tarsomere paler. Metacoxae reddish brown; metafemora red with apex black-brown. Metatibiae brown, with 3 lateral spines slightly yellowish basally and 8 apical, black-brown spines. Metatarsi dark brown, with a ventral row of 6 black spines on first tarsomere.

ABDOMEN. Bright red with genital segments black-brown.

MALE GENITALIA ( Fig. 33 View Fig ). Posterior margin of pygofer in lateral view sinuate, strongly roundly projecting at dorsal ½, moderately broad ventrally ( Fig. 33A, C View Fig ). Anal tube with lateral margins subparallel before epiproct, constricted at level of epiproct, then obovate in apical half, 2.33 times as long as broad, slightly curved ventrally in lateral view; apical margin roundly truncate ( Fig. 33A–B View Fig ). Gonostyli fused on basal 2/5 of length of centroventral part and projecting posterodorsally ( Fig. 33A, C View Fig ). Centroventral part broad and dorsoventrally flattened on basal 2/5, then with 2 strong divergent processes curved laterally and pointed apically ( Fig. 33A, C View Fig ). Laterodorsal part of gonostyli elongate and directed posterodorsally, laterally flattened, not surpassing centroventral part and strongly bifid apically, with the two pointed processes forming an open C and projecting posteriorly, dorsal process shorter than ventral one; lateral process elongate, projecting posterolaterally and slightly longer than spoon-shaped process ( Fig. 33A, C–D View Fig ). Dorsal portion of phallobase with hooked process on each side, progressively narrowing from base to apex, directed dorsally, slightly converging apically ( Fig. 33E–F View Fig ). Ventral portion of phallobase unilobed in dorsal view, broadly rounded apically and with median lobe surpassing phallus ( Fig. 33E– F View Fig ). Phallus dorsoventrally flattened, rather broad, with apical margin deeply emarginate in middle ( Fig. 33E–F View Fig ).

Female

Similar to male, but with markings on anterior and median legs less visible; tegmina with apical margin largely bordered with white; posterior wings with apical margin largely bordered with white, white area extending on 11 cells ( Fig. 34 View Fig. 34 ).

Distribution and biology

This species is currently recorded from Blue Bakers Mountain, an isolated mountain area in North Queensland ( Fig. 3 View Fig. 3 ), in the Einasleigh Upland Savanna bioregion. The specimens were collected in November in open forest at 800 m a.s.l. In an unpublished report available on the Internet, Ingram (1998) mentions that the location is a refuge with many endemic species of invertebrates (molluscs and isopods).
