Diagnosis

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

(1) hind wings without orange marking ( Figs 12EView Fig. 12, 14EView Fig. 14)

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

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

(4) centroventral part of gonostyli with long laminate process concave on ventral margin ( Fig. 13A, CView Fig. 13) (5) laterodorsal part of gonostyli with spinose process curved ventrally ( Fig. 13A, C–DView Fig. 13)

(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–DView Fig. 12). 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–DView Fig. 12). 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, CView Fig. 12). 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. 12EView Fig. 12). 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–DView Fig. 12). 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. 13View Fig. 13). Posterior margin of pygofer in lateral view strongly sinuate, strongly roundly projecting at dorsal ½, narrow ventrally ( Fig. 13A, CView Fig. 13). 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–BView Fig. 13). Gonostyli fused to slightly further than basal third of centroventral part and projecting posterodorsally ( Fig. 13A, CView Fig. 13). 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, CView Fig. 13). 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–DView Fig. 13). Dorsal portion of phallobase with strongly elongated process on each side, pointing dorsally and slightly internally ( Fig. 13E–FView Fig. 13). Ventral portion of phallobase along lateral margin of phallus on basal two thirds, then under phallus, narrowing and bifid apically, directed posterodorsally ( Fig. 13E–FView Fig. 13). Phallus dorsoventrally flattened, elongate, with apical margin emarginate in dorsal view ( Fig. 13E–FView Fig. 13).

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. 14View 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. 3View 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.
