Diagnosis

The wide frons near the apical transverse carina (at least 5 × as wide as median ocellus) and the strongly elevated lateral carinae on the frons place I. geminatus sp. nov. in the multimaculatus group. Innobindus geminatus can be distinguished from all other species within the multimaculatus group by the presence of a medium sized spine on each side of the phallotheca ( Fig. 12B ). All other species in this species group possess a large or medium-sized spine on one side of the phallotheca only.

Etymology

The Latin term ‘ geminatus ’ means ‘double’ or ‘pair’. Named after the arrangement of the aedeagal spines in ventral view, with a medium-sized spine and a minute spine occurring in pairs on each side of the phallotheca.

Description

COLOUR. Head light brown apart from mid brown central parts of frons and vertex. Pronotum light brown. Mesonotum mid brown. Forewings hyaline light brown, with dark markings in apical cells along the apical margin, one dark mark in the centre of clavus and usually two dark markings in the postcostal cell; veins slightly darker than cells; tubercles concolorous with veins. Legs light brown. Body mid to dark brown.

MEASUREMENTS. Body length: ♂ 6.4–6.6 mm; ♀ 6.9–7.4 mm.

HEAD. Vertex about 0.7 × as long as wide; apical transverse carina straight or incised (u-shaped); subapical transverse carina straight or slightly u-shaped; median carina of vertex covering ⅓ to ½ of entire length of basal compartment. Frons 2.1–2.3× longer than wide at frontoclypeal suture, about 1.9 × 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 wide (at least 5× as wide as median ocellus of frons); lateral carinae of frons in facial view sinuate; strongly elevated (distinctly higher elevated than median carina of frons); foliaceous, very distinctly extending laterally; lateral carinae of frons continuous with those of clypeus.

THORAX. Hind margin of pronotum acutely angled or rectangular. Forewing 2.7–3.4 × longer than wide; costal margin with 31–32 tubercles; fork of ScP+RA and RP distinctly basad of fork CuA1 and CuA2; crossvein r–m 1 slightly to distinctly basad of fork MP1+2 and MP3+4; transverse veinlet m–cu 1 where it inserts at CuA distinctly distad of transverse veinlet r–m 1; transverse veinlet m–cu 1 where it inserts at MP3+4 slightly basad of transverse veinlet r–m 1; icu, where it inserts at CuA, slightly to moderately distad of apex of clavus; RA bifid; MP3+4 bifid; crossvein m–cu 2 (delimiting subapical cell C4) slightly to moderately distad of crossvein icua (delimiting subapical cell C5); nodus of y-vein moderately to distinctly distad of centre of clavus. Hind leg: tibia with 6 apical spines and up to 2 minute to medium-sized 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. 12D–E . Pygofer and genital styles as in Fig. 12F–G : ventromedian process of pygofer narrow, 3-lobed, with a distinct constriction near base. Shaft of genital style slightly narrowed near base but without a distinct indentation. Aedeagus ( Fig. 12A–C ): phallotheca laterally with a short to medium-sized, slightly to moderately sclerotised, almost straight spine on each side (spines a, b), ventrally near base with a bifurcate process (d’); laterally on each side with a minute spine near level of ventral bifurcate process. Flagellum with a short, slightly sclerotised spine (c).

FEMALE GENITALIA. Segment IX truncate, with a disc bearing an elevated median carina running from ovipositor to anal tube. Anal tube medium length (about 1.5–2× longer than wide in lateral view). Ovipositor protruding slightly further caudally and as far dorsally as anal tube (including anal style). Anal style slightly longer than remainder of 11 th segment.
