Diagnosis
Innobindus artus 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 brownish (not whitish); at most one quarter of antennal pedicel covered by slightly foliaceous lateral carinae of frons (Fig. 2C). The latter two characters separate I. artus from the two similar looking species in the artus group, with whom it shares the very narrow frons (near apical transverse carina) and the colour pattern of the forewing. The forewing colour pattern of I. artus and I. kaanti is not as contrasting with pale areas as in I. loriensis. Innobindus artus has a prominent, thick, strongly sclerotised spine (c) on the flagellum (Fig. 8D). While other species in Innobindus have spines or spine-like ridges on the flagellum, they differ in the following: I. unicornis (very short and thin), I. loriensis (slightly sclerotised), I. geminatus (very short and slightly sclerotised) and I. kaanti (very long and wide spine-like ridge).
Etymology
The Latin term ‘ artus ’ means ‘narrow’, ‘tight’. Named after the narrow section of the frons near the apical transverse carina.

Description
COLOUR. Frons and postclypeus light to mid brown with concolorous carinae, sometimes lateral carinae of frons slightly paler. Anteclypeus slightly darker. Central area of vertex light brown, lateral areas mid to dark brown. Pronotum light brown. Mesonotum mid brown. Forewings hyaline colourless, with numerous mid and dark brown markings, including a transverse brown band of varying width (widest at fork CuA1 and CuA2) 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 sometimes darker than veins, sometimes concolorous. Legs light brown. Body light to mid brown.
MEASUREMENTS. Body length: ♂ 6.0– 6.5 mm; ♀ 6.3–7.7 mm.
HEAD. Vertex 0.6–0.7 × as long as wide; apical transverse carina incised (v-shaped); subapical transverse carina more or less straight; median carina of vertex covering ⅓ to ½ of entire length of basal compartment. Frons about 2.3× longer than wide at frontoclypeal suture, 1.9–2.1 × longer in widest part; maximum width of frons more than twice apical width, broadening over a short distance, lateral carinae slightly concave; frons near apical transverse carina very narrow (2–3× as wide as median ocellus of frons); lateral carinae of frons in facial view convex, rectilinear apically or sinuate; slightly extending laterally; in facial view at most one quarter of antennal pedicel covered by slightly foliaceous lateral carinae.
THORAX. Hind margin of pronotum obtusely angled. Forewing 2.5–2.7× longer than wide; costal margin with 21–29 tubercles; fork of ScP+RA and RP slightly 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 or slightly basad of transverse veinlet r–m 1; transverse veinlet m–cu 1 where it inserts at MP3+4 slightly distad of, or at same level as transverse veinlet r–m 1; icu, where it inserts at CuA, slightly 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 distinctly distad of centre of clavus. Hind leg: tibia with 6 apical spines and up to 2 minute lateral spines; 1 st tarsomere with 7 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. 8E–F. Pygofer and genital styles as in Fig. 8G–H: ventromedian process of pygofer narrow, subtriangular. Shaft of genital styles with a distinct, u-shaped indentation; in ventral view genital styles very long and narrow. Aedeagus (Fig. 8A–D): phallotheca left laterally with a medium sized, curved spine (a), right laterally with a very long, curved spine (b); ventrally with several twisted, sclerotised ridges (d’).
FLAGELLUM. With a prominent, strongly sclerotised spine (c).
FEMALE GENITALIA. Segment IX rounded or truncate, with rounded edges, carinae absent. Anal tube short to medium length. Ovipositor protruding further caudally and dorsally than anal tube (including anal style).
