Diagnosis. Infectostriatus absentis sp. nov. is most easily differentiated from I. differens sp. nov. by the absence of punctation between the seventh and tenth striae between the base and elytral fascia.

Description. Habitus: Fig. 149 . Total length: 6.7–9.7 mm. Head: Vertex, frons, genae and gula black, clypeus and supra-antennal elevation dark reddish-brown, anteclypeus, labrum, antennae and palpi orange-brown or chestnut-brown; frons narrow (eyes separated by 0.5–0.8 eye widths), weakly impressed above narrowest point, frontal sculpturing confused-foveolate, often transversely wrinkled below narrowest point, genae wrinkled; exterior margins of terminal palpomeres about 1.6 times (maxillae) and 3 times (labium) the length of inside edges; antennae reaching near base of pronotum; eyes and most of cranium vested with erect pale setae, frons with shorter medially-directed setae. Prothorax: Pronotum dark reddish-brown to reddish-black, darkest laterally, sometimes paler at anterior and posterior margins and ventrally; pronotum 1.24–1.3 times longer than wide, anteriorly slightly narrower than head, sides impressed above conspicuous lateral tubercle, subapical depression deeply v-shaped, disc weakly tuberculate behind prontal arch, sulcate centrally; surface smooth with only occasional small seta-associated punctures, well-vested in short fine multi-directional setae and occasional long erect setae. Pterothorax: Ventrites orange-brown, impunctate, moderately vested with short pale and occasional long setae; elytra ( Fig. 15 ) brown with yellowish markings (a large apical macula, a broad ‘stepped’ central fascia and a variable irregular sub-basal macula—sometimes thin and running obliquely from the suture towards the fascia and joined to it along the suture, or sometimes broadly connected to the fascia and enclosing a small dark spot), length to width ratio 2.6–2.8:1, punctation with lateral bead-like nodules, 8 th and 9 th striae highly reduced, evident only within dark area between fascia and apical macula, 8 th stria beginning between the tenth and fifteenth puncture of the 7 th stria, the 9 th stria represented by a few punctures only, punctation relatively large until near apex; disc well-vested in very fine short and thicker erect setae, short setae on anterior and lateral perimeter of punctations and within interstriae, longer setae in rows following interstriae, epipleurae extending well into apical curve; hindwing with CuA 3+4 and CuA 1 cross-veins complete, MP 3+4 basad of CuA 1 crossvein small (but not completely absent). Legs: Femora bicoloured, basally yellow (basal half of profemora, basal three-quarters of meso- and metafemora), apically brown, tibiae and tarsi brown, ventral tarsal pads yellowish; profemora slightly swollen, other femora slender. Abdomen: Ventrites orange. Male genitalia: Tegmen ( Fig. 37 ) robust, slightly narrowing before parameroid lobes, the latter angularly expanded laterally, bent inwards and blunt (not pointed) apically, dorsal sinus very wide, just over one-quarter tegmen length, slender transparent (sensory?) membrane apparent at broadest point, ventral sinus almost as long, tegminal arms sharply meeting apodeme, apodeme just over quarter tegmen length; median lobe as in Fig. 76 ; pygidium as in Fig. 112 .

Etymology. The specific epithet absentis (Latin, meaning absent or missing) refers to the total absence of basal punctures between the seventh and tenth elytral striae.

Biology. Adults have been collected from January to July, many by light trapping.

Distribution (Map 2). Atherton Tableland (Parada, Tolga, Station Creek), Cooktown and Coen in far north Queensland.
