description: Genus Innobindus Jacobi, 1928
Innobindus Jacobi, 1928: 31.
Type species
Innobindus multimaculatus Jacobi, 1928, by monotypy.
Diagnosis
Innobindus can be distinguished from all other Australian Cixiidae by a combination of the following characters: median carina of frons present (covering large parts of frons); pronotum without ovoid, inflated areas (as present in Cajetini); forewing with posterior subcostal (ScP), radial (R) and posterior medial (MP) veins forming a common stem that is at least more than 6× the diameter of a tubercle; tubercles present only along veins (not in cells); median ocellus on the frons present; denticle on distal part of fore coxa absent.
Description (amended from Löcker 2007)
MEASUREMENTS. Body length: ♂ 5.0– 7.4 mm; ♀ 5.7–7.7 mm.
HEAD. Vertex with u-or v-shaped basal emargination; lateral carinae strongly elevated (raised); vertex much wider at base (posterior end) than at apex; median carina absent or present; apical and subapical carina well developed, straight or slightly u- or v-shaped. Maximum width of frons more than 2× apical width, evenly widening from apex to maximum width or broadening over a very short distance, therefore lateral carinae slightly to distinctly concave; maximum width of frons distinctly dorsad of centre of frontoclypeal suture; lateral carinae slightly to strongly foliaceous (except for I. gimani); median carina incomplete but covering large part of frons; frontoclypeal suture slightly semicircular bent upwards, median part below (not reaching level of) lower margin of antennal scape; median ocellus present. Median and lateral carinae of postclypeus well developed; median carina of anteclypeus well developed; lateral carinae absent. In dorsal view head including eyes much narrower than pronotum. Rostrum surpassing hind coxae (rarely only reaching hind coxae).
THORAX. Pronotum with hind margin acutely or obtusely angled or rectangular; median carina present; submedian carinae (= postocular carinae) running parallel to eye. Mesonotum with 3 carinae, lateral carinae moderately to well-developed, median carina weakly to well-developed, usually evanescent near posterior border. Forewing steeply tectiform, apices of wings touching; costal border with slight to moderate concavity; tubercles along veins; ScP+R+MP fused, forming long common stem; fork of ScP+RA and RP at same level as or basad of fork CuA1 and CuA2; crossvein r–m 1 slightly to distinctly basad of, or at same level as fork MP1+2 and MP3+4, rarely slightly distad; icu distad of apex of clavus; RP apically trifid; additional subapical cell between branches of RP present; MP1+2 trifid; MP3+4 bifid (rarely trifid); CuA1 and CuA2 apically unforked; nodus of y-vein (fork PCu and A1) moderately to distinctly distad of centre of clavus (rarely slightly distad or central within clavus); subapical cell C5 distinctly longer than subapical cell C4. Hind leg: tibia with 0–8 minute to medium sized lateral spines (= Laterometatibial spines) and with 6–7 apical spines either forming uninterrupted row of spines or with small gap, dividing spines in two groups of 3–4 spines; 4 th spine (counted from the outer side) longer (= protruding further towards 2 nd hind tarsomere) than 3 rd spine; 1 st tarsomere (Fig. 6E) with 7 (rarely 8) teeth; 2 nd tarsomere with 8 (rarely 7); tarsomeres without platellae (except for I. marginatus); 2 nd tarsomere with 0–3 fine setae underneath row of apical teeth (except for I. marginatus).
MALE GENITALIA. Aedeagus with 1–4 spines of varying length, some of which arise on phallotheca, some on flagellum; bifurcate ventral process on phallotheca absent or present.
FEMALE GENITALIA. Waxplate absent. Ovipositor very long, sabre-shaped, strongly curved upwards towards anal tube (Fig. 1).
Distribution
Australia (Qld, NSW).

Key to species of Innobindus Jacobi, 1928
This key allows identification of males to species level. Females can be identified to species group level, with some females identifiable to species level. This key should be used in conjunction with the revision of the genus (Löcker et al. 2007) as characters relating to previously described species are illustrated in the above mentioned research paper.
