Taxonomy
The holotype of Crambopsis malacelloides Bleszynski, 1955: 229, figs. 3, 6 from Australia (Tasmania), is in Warsaw.
Description
A handsome species. Distally from the black FW costa is a broad white, median, longitudinal streak. In the submarginal area the the streak is notched and then expands to the termen. Apically either side of the acutely angled subterminal line the subcosta has four short white streaks. Another broad longitudinal streak extends along the rear margin. The HW is mainly pearly white but suffused with brown around the subcosta and radius veins.
Superficially it is almost indistinguishable from Crambus malacellus Duponchel, 1836, (the TS of Bleszynskia de Lattin, 1961: 115 = Angustalius Marion), which is a Mediterannean and African species (Slamka 2008, Globiz). For details of the characters see Bleszynski (1965) who gives a full description of the genitalia of B. mallaceloides (male fig. 3, female fig. 6) and A. mallacellus (230-231, venation fig. 22g, male genitalia, pl. 54, fig. 144), as does Slamka (2008: 36; Pls. 5, 7 & 35)
There is a specimen in the Agricultural Research Centre, Tuaran (Sabah) under Chilo partellus (Swinhoe, 1885: 879) but it is not that sp.
