Warrumiris  gen. nov.

Type species. Warrumiris viridis  sp. nov. by original designation.

Diagnosis. Warrumiris  is recognised by the following combination of characters: male elongate; female elongate, slightly ovoid ( Fig. 1 View Figure ); dorsum with dense distribution of brown bristle-like setae; head, pronotum and scutellum with moderate distribution of pale and brown bristle-like setae ( Figs. 1 View Figure , 2a, c, d View Figure ); head long and subrectangular in lateral view, with clypeus truncate ( Fig. 2c View Figure ); humeral angle of pronotum rounded ( Fig. 2d View Figure ); AI longer than interocular distance ( Fig. 2a View Figure ); AII much longer than posterior margin of pronotum; ventral margin of genital opening with peglike setae ( Fig. 2g, h View Figure ); parameres reaching midpoint of pygophore ( Figs. 2g, h View Figure , 3a View Figure ); left paramere t-shaped, sensory lobe strongly pointed, apophysis elongate, with apex recurved ( Figs. 2g, h View Figure , 3c View Figure ); right paramere digitiform, denticulate, with serrate mediodorsal flange ( Fig. 3b View Figure ); phallotheca simple, opened ventrally, with right basal tumescence ( Fig. 3d, e View Figure ); aedeagus relatively simple, lobal sclerites with broad membraneous skirt ( Fig. 3f, g View Figure ).

Description. VESTITURE. Dorsum densely distributed with moderately long, semierect, brown bristle-like setae ( Fig. 1 View Figure ). AI, head, pronotum, mesoscutum and scutellum moderately distributed with moderately long, semierect, brown bristle-like setae, intermixed with sparsely distributed long, erect, pale bristle-like setae ( Figs. 1 View Figure , 2a, c, d View Figure ).

STRUCTURE. Body elongate and parallel-sided ( Fig. 1 View Figure ). Head long, transverse, strongly flattened, subrectangular in lateral view, vertex posterior margin straight ( Figs 1 View Figure , 2a View Figure ); eyes large, just extending beyond anterolateral angles of pronotum, coplanar with vertex; clypeus truncate, visible from dorsal view; mandibular plate relatively large; maxillary plate small; bucculae arcuate, extending to posterior margin of head ( Fig. 2a, c View Figure ). Antennae inserted near ventral margin of eyes in lateral view ( Fig. 2c View Figure ); AI cylindrical, thick; longer than interocular distance ( Fig. 1 View Figure , 2a View Figure ); AII cylindrical; narrow, elongate, longer than posterior width of pronotum; AIII slightly longer than AI; AIV threadlike, short. Labium reaching tip of mesocoxae, L1 extending to posterior margin of proxyphus ( Fig. 2b View Figure ). Pronotum subtrapeziform, callosite region weakly demarcated, approx. ¼ of disc; lateral margins moderately divergent; posterior margin of pronotum weakly excavate to slightly sinuate; humeral angles strongly rounded ( Fig. 2d View Figure ). Mesoscutum broadly exposed ( Fig. 2d View Figure ). Metathoracic spiracle opening elongate, obliquely oriented. External efferent system moderately developed, reaching level of mesepimeron, peritreme short, flat, triangular ( Fig. 2e View Figure ). Hemelytra moderate siZed, with cuneus long and broad, minor cell of hemelytral membrane relatively large, reaching midpoint of medial margin of cuneus ( Fig. 1 View Figure ). Male abdomen reaching middle of membrane, well beyond tip of cuneus; female abdomen extending to base of cuneus. Femora slender, flattened; metatibia with small, acute, vertically continuous spines; pretarsus with parempodia apically convergent ( Fig. 2f View Figure ).

MALE GENITALIA. Pygophore weakly asymmetrical, with peglike setae present on ventral margin of genital opening ( Fig. 2g, h View Figure ). Parameres reaching midpoint of genital opening ( Figs. 2g, h View Figure , 3a View Figure ). Left paramere t-shaped, sensory lobe strongly pointed, smooth, with apical tooth, apophysis elongate, narrow, distally tapered, with apex recurved ( Figs. 2g, h View Figure , 3c View Figure ). Right paramere fingerlike, apically rounded and denticulate, mediodorsal flange slightly elongate, rounded and denticulate ( Fig. 3b View Figure ). Phallotheca apically reflexed to left hand side, ventrally opened, opening broad apically, narrow laterally, with right basal tumescence ( Fig. 3d, e View Figure ). Aedeagus with four elongate, weakly arcuate lobal sclerites, connected to basal membranous skirt ( Fig. 3f, g View Figure ).

Etymology. Named after the prefix of the type locality district, the Warrumbungles; and the suffix miris, in reference to its membership of the family.

Remarks. Warrumiris  is recognised by long, subrectangular head and long first antennal segment. It is also has a t-shaped left paramere and elongate lobal sclerites connected basally be membrane. It is unlike all other Australian Orthotylini  , where endosomal spicules are present as elongate processes, that are sclerotised, extending basal to the secondary gonopore, and are attached to the apex of the ductus seminis by a shortened membraneous region.
