Infectostriatus gen. nov.

ZooBank registration: urn:lsid:zoobank.org:act:C11736E5-943C-41E5-8D14-DF24D7BF7B65

Gender. Masculine.

Type species. Infectostriatus absentis sp. nov., by present designation.

Diagnosis. Intrafoveal setae short but visible under magnification; basitarsi without a distinct ventral pad; ninth elytral stria absent ( Fig. 15 ); inside lateral rims of elytral punctures with nodules; elytral interstriae with several setae distributed across interval width; elytral striae terminating near apices; apical lobes of median lobe with rearward-directed spine or barb.

Description. Eyes coarsely-facetted, strongly emarginate above supra-antennal elevations, separated by 0.5– 0.8 eye widths; antennal scape with carina bordering each side of flattened rear face; sensory face of terminal maxillary palpomere 1.6 times longer than inside margin; sensory face of terminal labial palpomere 2.3–3.0 times longer than inside margin; genae wrinkled; pronotum 1.15–1.3 times longer than wide, broadest near middle, disc lightly to heavily punctate, median sulcus present; elytra 2.44–2.8 times longer than wide at humeri, punctures with nodules, eighth stria with post-basal/pre-apical interruption or beginning between tenth and fifteenth puncture of seventh stria, ninth stria absent, most marginal and discal striae terminating near apices, interstrial setae not in single rows (often several setae across interval width), intrafoveal setae present; hindwing with CuA 3+4 cross-vein complete, CuA 1 cross-vein complete, RP not incurvate; tarsomeres 2–4 each with a well-developed ventral pad; tegmen ventral sinus as long as, or longer than dorsal sinus; median lobe with apico-lateral spine.

Etymology. The generic epithet Infectostriatus (from Latin ‘infectus’ meaning unfinished, and ‘stria’ meaning line or furrow) refers to the synapomorphic absence or reduction of the 8 th and 9 th elytral striae (i.e., intervals).

Remarks. Infectostriatus gen. nov. contains two species from far north Queensland.
