Plusiodonta wahri sp. n.
14mm, possible 16mm. The male forewing resembles that of a rather drab form of coelonota with the area between the oblique fasciae and the tornus rather pale, not particularly golden, and with the darker delineation within it somewhat more regular, such as for the triangle based on the dorsum immediately distal to the fascia; this extends inwards and has a slightly paler spot at its apex. These features also occur in the putative female, which additionally has further paler patches distal to the fascia more anteriorly and also in a band subbasally as illustrated. In the male genitalia the distal process of the valves is more robust, curved rather than angled around the margins, and is more distinctly bifid at the apex. The interior saccular process is short, wider than in coelonota and rather square. The interior margin of the sacculus also has a prominent subbasal lobe that bears numerous coarse, short spines. The aedeagus has a distinctive lateral process that is sinuous, with a serrated distal margin. The vesica is small, cylindrical, with a cluster of small spines distally. In the putative female, the ostium and ductus are very broad and finely rugose, the breadth possibly to accommodate the process on the aedeagus.
