Diagnosis

Innobindus gimani sp. nov. is the only species within Innobindus that does not have foliaceous lateral carinae, which means even the basal parts of the antennal pedicel are visible in facial view ( Fig. 5C ). Most other species of Innobindus have distinctly foliaceous lateral carinae that cover large parts of the antennal pedicel, e.g., Innobindus kaanti ( Fig. 3C–D ), whereas some species have only slightly foliaceous lateral carinae, e.g., Innobindus oppositus ( Fig. 7C–D ).

Etymology

‘Gimani’ means ‘knee’ in Gooniyandi, an Aboriginal language spoken in Western Australia (Thieberger & McGregor 1994). Named after the aedeagal spine (b) which in left lateral view resembles a leg bent at the knee.

Description

COLOUR. Carinae of head light brown; disc of face and vertex usually darker; central area of vertex mid brown, lateral parts of vertex dark brown, with a paler area in between. Pronotum light brown. Mesonotum mid brown; carinae sometimes slightly paler; sometimes area around lateral carinae darker. Forewings hyaline whitish with a dark brown spot in centre of clavus and at apex of clavus; often with further dark markings near apex of wing; pterostigma dark brown; veins alternating whitish and dark brown areas, giving it a speckled appearance; crossveins generally dark brown; tubercles concolorous with veins. Legs light brown. Body mid to dark brown.

MEASUREMENTS. Body length: ♂ 5.4–6.0 mm; ♀ 6.0– 6.3 mm.

HEAD. Vertex 0.7–0.8× as long as wide; apical transverse carina straight or slightly u- or v-shaped; subapical transverse carina more or less straight or slightly u-shaped; median carina of vertex covering ½ to ¾ of entire length of basal compartment. Frons 1.9–2.0× longer than wide at frontoclypeal suture, about 1.7× longer in widest part; maximum width of frons more than twice apical width, steadily broadening; frons near apical transverse carina wide (at least 5× as wide as median ocellus of frons); lateral carinae of frons in facial view convex, rectilinear apically or slightly sinuate; lateral carinae only slightly to moderately elevated (slightly higher elevated than median carina), not foliaceous; in most specimens lateral carinae of frons and clypeus not continuous but with a very slight indentation at junction of frons and clypeus.

THORAX. Hind margin of pronotum obtusely angled or rectangular. Forewing about 2.9× longer than wide; costal margin with 24–27 tubercles; fork of ScP+RA and RP slightly to moderately basad of fork CuA1 and CuA2; crossvein r–m 1 slightly basad of, or at same level as fork MP1+2 and MP3+4; transverse veinlet m–cu 1 where it inserts at CuA slightly distad of transverse veinlet r–m 1; transverse veinlet m–cu 1 where it inserts at MP3+4 slightly basad of, or at same level as transverse veinlet r–m 1; icu, where it inserts at CuA, slightly to moderately distad of apex of clavus; RA bifid (rarely unforked); MP3+4 bifid; crossvein m–cu 2 (delimiting subapical cell C4) distinctly distad of crossvein icua (delimiting subapical cell C5); nodus of y-vein moderately distad of centre of clavus. Hind leg: tibia with 6 apical spines and 2–7 minute to medium-sized lateral spines; 1 st tarsomere with 7 (rarely 9) apical teeth and no platellae; 2 nd tarsomere with 8 apical teeth, no platellae, but up to 3 very fine setae.

MALE GENITALIA. Anal tube as in Fig. 11C–D . Pygofer and genital styles as in Fig. 11E–F : ventromedian process wide, subtriangular, with a slight constriction near base. Shaft of genital style with a moderate to distinct indentation. Aedeagus ( Fig. 11A–B ): phallotheca dorsally with a long spine (a); left laterally with a thick, spine (b), strongly bent (about 90 degrees) at midlength with its tip pointing ventrad; ventrally with a short, curved spine (c) with its tip directed dorsad and a bifurcate process (d’). Flagellum without spines or spine-like ridges.

FEMALE GENITALIA ( Fig. 1A ). Segment IX rounded, carina absent. Anal tube short (about 1–1.5× as long as wide in lateral view). Ovipositor protruding as far caudally but not as far dorsally as anal tube (including anal style). Anal style slightly longer than remainder of 11 th segment.

Distribution

Central upland NSW ( Fig. 14B ).

Remarks

Females appear darker in colour with numerous dark markings and transverse bands that are not present in males.
