Figs 3, 12–14

Diagnosis

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

(1) hind wings without orange marking (Figs 12E, 14E)

(2) pro- and mesofemora and -tibiae largely black-brown (Figs 12A–D, 14A–D)

(3) anal tube of male oblong, with posterior margin narrowly rounded (Fig. 13B)

(4) centroventral part of gonostyli with long laminate process concave on ventral margin (Fig. 13A, C)

(5) laterodorsal part of gonostyli with spinose process curved ventrally (Fig. 13A, C–D)

(6) rather large size: 9–10 mm

Etymology

This species is dedicated to Dr Hannelore Hoch, who collected the paratypes series together with Dr Manfred Asche. But ladies first!

Male

HEAD (Fig. 12A–D). Vertex concave, with anterior and posterior margins parallel, curved; dark brown variegated with yellowish in middle. Frons black-brown, slightly tinged with reddish medioventrally. Clypeus elongate, black-brown with 2 short, black, longitudinal lines at base, with oblique reddish lines on sides and with apex darker. Genae brown with yellowish markings along anterior margin. Labium black, reaching metacoxae. Antennae black; scape short, ring-shaped; pedicel subcylindrical, slightly narrowing towards apex.

THORAX (Fig. 12A–D). Pronotum dark brown with some yellowish markings; slightly transversely wrinkled posteriorly; obsolete median carina and 2 small impressed points on disc. Lateral fields of prothorax dark brown. Mesonotum black-brown with reddish markings along posterior margin, median yellowish spot along anterior margin and at apex of scutellum; slightly wrinkled; median and peridiscal carinae weakly marked; median carina stopping before scutellum; slight impression before scutellum. Red ventrally. Tegulae brown.

TEGMINA (Fig. 12A, C). Dark brown with small yellowish or reddish spots; bigger, yellowish, slightly transverse spot on middle of clavus; large triangular white marking on costal margin on nodal line; white spot at apicosutural angle. Maximum breadth at nodal line; costal margin slightly sinuate; apical margin obliquely rounded.

POSTERIOR WINGS (Fig. 12E). Brown with apical ½ black-brown; transverse, broad, subtriangular white marking at apicocostal angle, extending on 6 cells. Margin of anal area sinuate; sutural margin with 2 clefts, cubital one slightly marked.

LEGS (Fig. 12A–D). Pro- and mesocoxae dark brown. Pro- and mesofemora black-brown with reddish spots marking 2 obsolete rings. Pro- and mesotibiae black-brown with 3 obsolete ring-shaped reddish or yellowish markings, larger one near apex. Pro- and mesotarsi dark brown. Metacoxae reddish brown; metafemora red with apex dark brown. Metatibiae brown, with 3 lateral spines yellowish basally and 8 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. 13). Posterior margin of pygofer in lateral view strongly sinuate, strongly roundly projecting at dorsal ½, narrow ventrally (Fig. 13A, C). Anal tube oblong, 3.6 times as long as broad, slightly curved ventrally in lateral view; slightly constricted on basal ½ and narrowing towards apex in dorsal view; lateral margins sinuate and slightly curved ventrally on apical ¾; apical margin narrowly rounded (Fig. 13A–B). Gonostyli fused to slightly further than basal third of centroventral part and projecting posterodorsally (Fig. 13A, C). Centroventral part dorsoventrally flattened basally, progressively twisted and laminate towards apex and with ventral margin concave in lateral view; slightly broader apically in lateral view with apical margin strongly sinuate, apicodorsal angle pointed and apicoventral angle rounded (Fig. 13A, C). Laterodorsal part of gonostyli with ventrally strongly curved, hooked process, with lateral process rather broad and about as long as spoon-shaped process (Fig. 13A, C–D). Dorsal portion of phallobase with strongly elongated process on each side, pointing dorsally and slightly internally (Fig. 13E–F). Ventral portion of phallobase along lateral margin of phallus on basal two thirds, then under phallus, narrowing and bifid apically, directed posterodorsally (Fig. 13E–F). Phallus dorsoventrally flattened, elongate, with apical margin emarginate in dorsal view (Fig. 13E–F).

Female

Similar to male, but darker; frons entirely black-brown; markings on pro- and mesofemora nearly absent; markings on pro- and mesotibiae reduced; white markings on tegmina smaller (Fig. 14).

Distribution and biology

This species is currently known from a series of ten specimens collected near Undara Lava Tubes in North Queensland (Fig. 3), in the Einasleigh Upland Savanna bioregion. All specimens were collected in January, on the same day; hence, the species is probably not scarce in its habitat.
