Diagnosis. Agrotera longitabulata   resembles A. nemoralis   and A. genuflexa   in the sinuate termen and the simple, continuous and dark brown postmedial line of the forewing, but can be distinguished from A. nemoralis   by a pale yellow hindwing base and a conspicuous dark brown costal spot in the basal field of the forewing, and from both A. nemoralis   and A. genuflexa   by the undivided valva and a long, slender and band-shaped saccus in the male genitalia. In the female genitalia, A. longitabulata   differs from A. genuflexa   by the long ductus bursae, the long narrow colliculum and the small, laterally attached corpus bursae. Agrotera longitabulata   resembles A. posticalis Wileman, 1911   and A. basinotata   (illustration of adult could be found at https://www.biodiversitylibrary.org/item/ 180088#page/187/mode/1up) in wing pattern, but can be distinguished by the band-shaped saccus and the sickleshaped upcurved fibula-like process emerging from below the base of the costa.

Description. Frons pale yellow, vertex orange, thorax yellow with orange scales; labial palpus laterally grey with long, ventrally projecting scales; legs in male unmodified. Abdomen in male long, slender; segments 1–5 pale yellow with orange scales, terminal 3 segments grey, 3–8 with blackish hind margin. Wingspan 17–22.5 mm. Forewing subtriangular, termen sinuate; basal third pale yellow, reticulated with orange, distally edged by a scalloped antemedial line of orange and brown scales, remainder of wing purplish grey; terminal margin brown; conspicuous dark fuscous spot at 1/10 of costa; reniform stigma crescentic, outwardly followed by ovate orange spot; postmedial line grey-brown but darker on costa, from 4/5 of costa slightly sinuate to CuA1, bent to middle of CuA2 then to 3/4 of posterior margin; fringe grey-brown and pale yellow, with yellow bars below apex, before middle and before tornus. Hindwing fan-shaped; basal third pale yellow with few orange scales outwardly edged by brown scales, pale yellow along anal margin with an orange longitudinal streak, remainder of wing purplish grey; postmedial line pale brown, weak, darkest on edge to pale yellow anal margin, then vanishing; terminal margin brown; fringe grey-brown in costal half, remainder pale yellow. Male genitalia ( Fig. 8 View FIGURES 7–10 ). Uncus small, subtriangular, rounded at apex. Tegumen trapezoidal, with obvious shoulders. Vinculum V-shaped. Saccus extremely long (approximately of valva length), slender, band-shaped, slightly tapering to truncate tip. Valva narrowly elliptical with acinaciform apex, undivided; transtilla two triangular lobes from base of costa, their points slightly downcurved, meeting in the middle; costa broadly sclerotized to beyond middle of valva; sacculus to 3/5 of valva, broad, densely setose on inner side, inner margin projecting as triangular point; with a very slender, sickleshaped upcurved fibula-like process from ventral base of costa. Juxta shield-shaped, distal half bifid. Phallus long, nearly parallel-sided, slightly downcurved at base; vesica in distal third with long, dense, sclerotized spinules and a large band-shaped sclerite. Female genitalia ( Fig. 10 View FIGURES 7–10 ). Antrum membranous, funnel-shaped, colliculum long, sclerotized, with two spinulose spikes. Ductus seminalis originating from anterior end of colliculum. Ductus bursae long, posterior part slightly wrinkled; corpus bursae small, laterally attached, without signum; ductus bursae and corpus bursae spinulose.

Distribution. Australia (Queensland).

Etymology. The specific name is derived from the Latin longi - = long and tabulatus = band-shaped, referring to the long, band-shaped saccus.

Remark. According to Shaffer et al. (1996), A. basinotata   occurs in Australia. However, our examination of genitalia reveals that specimens identified as A. basinotata   by Shaffer, are indeed the new species A. longitabulata   . The differences of these two superficially similar species are given above at the diagnosis of A. longitabulata   . Currently, no specimen of A. basinotata   is collected in Australia.
