description: 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); 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, 2a, c, d); head long and subrectangular in lateral view, with clypeus truncate (Fig. 2c); humeral angle of pronotum rounded (Fig. 2d); AI longer than interocular distance (Fig. 2a); AII much longer than posterior margin of pronotum; ventral margin of genital opening with peglike setae (Fig. 2g, h); parameres reaching midpoint of pygophore (Figs. 2g, h, 3a); left paramere t-shaped, sensory lobe strongly pointed, apophysis elongate, with apex recurved (Figs. 2g, h, 3c); right paramere digitiform, denticulate, with serrate mediodorsal flange (Fig. 3b); phallotheca simple, opened ventrally, with right basal tumescence (Fig. 3d, e); aedeagus relatively simple, lobal sclerites with broad membraneous skirt (Fig. 3f, g).
Description. VESTITURE. Dorsum densely distributed with moderately long, semierect, brown bristle-like setae (Fig. 1). 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, 2a, c, d).
STRUCTURE. Body elongate and parallel-sided (Fig. 1). Head long, transverse, strongly flattened, subrectangular in lateral view, vertex posterior margin straight (Figs 1, 2a); 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). Antennae inserted near ventral margin of eyes in lateral view (Fig. 2c); AI cylindrical, thick; longer than interocular distance (Fig. 1, 2a); 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). 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). Mesoscutum broadly exposed (Fig. 2d). Metathoracic spiracle opening elongate, obliquely oriented. External efferent system moderately developed, reaching level of mesepimeron, peritreme short, flat, triangular (Fig. 2e). Hemelytra moderate siZed, with cuneus long and broad, minor cell of hemelytral membrane relatively large, reaching midpoint of medial margin of cuneus (Fig. 1). 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).
MALE GENITALIA. Pygophore weakly asymmetrical, with peglike setae present on ventral margin of genital opening (Fig. 2g, h). Parameres reaching midpoint of genital opening (Figs. 2g, h, 3a). Left paramere t-shaped, sensory lobe strongly pointed, smooth, with apical tooth, apophysis elongate, narrow, distally tapered, with apex recurved (Figs. 2g, h, 3c). Right paramere fingerlike, apically rounded and denticulate, mediodorsal flange slightly elongate, rounded and denticulate (Fig. 3b). Phallotheca apically reflexed to left hand side, ventrally opened, opening broad apically, narrow laterally, with right basal tumescence (Fig. 3d, e). Aedeagus with four elongate, weakly arcuate lobal sclerites, connected to basal membranous skirt (Fig. 3f, g).
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.
