Diagnosis

Innobindus kaanti sp. nov. can be distinguished from all other species of Innobindus by the following combination of characters: frons near apical transverse carina very narrow (about 3× the width of median ocellus of frons); lateral areas of frons whitish; phallotheca ventrally with a single spine (c) ( Fig. 9B ). The shaft of the genital style has a very deep u-shaped indentation ( Fig. 9E ). Whilst an indentation can be seen in other species of Innobindus , e.g., I. loriensis , I. artus and I. collessi , it is usually not developed to such an extent.

Etymology

‘Kaanti’ means ‘take away’ or ‘remove something far away’ in Paakantyi, an Aboriginal language spoken along the Darling River (Thieberger & McGregor 1994). Named after the deeply indented shaft of the male genital style, which looks like a section has been taken away.

Description

COLOUR. Head light brown apart from whitish lateral parts of frons and vertex and whitish areas on genae. Pronotum whitish. Mesonotum mid to dark brown, central area including carinae slightly paler. Forewings hyaline colourless, with numerous mid and dark brown markings including a transverse brown band of varying width in basal half of wing, and a transverse brown band with a few pale patches covering the apex of wing; veins light to mid brown, tubercles concolorous with veins. Legs light brown. Body light to mid brown.

MORPHOLOGY. Body length: ♂ 5.4–5.5 mm; ♀ 6.5mm.

HEAD. Vertex 0.7× as long as wide; apical transverse carina incised (v-shaped); subapical transverse carina straight; median carina of vertex covering ⅛ to ⅓ of entire length of basal compartment. Frons about 2.2–2.6 × longer than wide at frontoclypeal suture, 1.8–2.1 × longer in widest part; maximum width of frons more than twice apical width, broadening over a short distance, lateral carinae strongly concave; frons near apical transverse carina very narrow (2–3× as wide as median ocellus of frons); lateral carinae of frons in facial view sinuate; in facial view at least half of antennal pedicel covered by strongly foliaceous carinae that distinctly extend laterally.

THORAX. Hind margin of pronotum acutely angled. Forewing with costal margin with 18–25 tubercles; fork of ScP+RA and RP moderately to distinctly basad of fork CuA1 and CuA2; crossvein r–m 1 slightly distad of, or at same level as fork MP1+2 and MP3+4; transverse veinlet m–cu 1 where it inserts at CuA basad of transverse veinlet r–m 1; transverse veinlet m–cu 1 where it inserts at MP3+4 at same level as transverse veinlet r–m 1; icu, where it inserts at CuA, slightly to distinctly distad of apex of clavus; RA bifid; MP3+4 bifid; crossvein m–cu 2 (delimiting subapical cell C4) distinctly distad of crossvein icua (delimiting subapical cell C5); nodus of y-vein very distinctly distad of centre of clavus. Hind leg: tibia with 6 apical spines and 2–3 minute to small lateral spines; 1 st tarsomere with 7 apical teeth and no platellae; 2 nd tarsomere with 8 (rarely 7) apical teeth, no platellae, but up to 3 very fine setae.

MALE GENITALIA. Anal tube as in Fig. 9C–D . Pygofer and genital styles as in Fig. 9E–F : ventromedian process of pygofer subtriangular, with a slight constriction near base. Shaft of genital styles with a deep u-shaped indentation; in ventral view genital styles very long and narrow. Aedeagus ( Fig. 9A–B ): phallotheca dorsally with a moderately sclerotized spine-like ridge (a’) and a medium-sized, spirally twisted spine (b), ventrally with a medium-sized, slightly curved, strongly sclerotised spine (c). Flagellum with a large, moderately sclerotised, spine-like ridge (d’).

FEMALE GENITALIA. Segment IX truncate, with a disc bearing an elevated median carina running from ovipositor to anal tube. Anal tube long (about 2 × longer than wide in lateral view). Ovipositor protruding further caudally and dorsally than anal tube (including anal style). Anal style slightly longer than remainder of 11 th segment.
