 “Eilema” brevivalva sp. n

"Eilema" brevivalva (holotype)
(x 1.32)

"Eilema" ?brevivalva
(x 1.32)

11-13mm, probable 12-13mm. Males of this species have a patch of rufous scales on the forewing underside posterior to the anal vein as in sandakana, with the basal part of the dorsal margin expanded, but are more a pale fawn on the upperside with a darker greyer zone at the forewing apex on both surfaces. The forewing venation also differs, with R2 stalked with R3-5. The female has similar venation, but the forewing is a uniform pale grey, including the costal margin. The male genitalia are very different from those of sandakana apart from the aedeagus, where there are similar globular and narrow diverticula bearing apical cornuti, but the narrow one is much more elongate. There is a spur at the apex of the aedeagus, but very much smaller than in sandakana. Whilst the saccus is narrow and rectangular, and there are weak and less rugose sclerotisations in the diaphragm, the arched juxta structure of sandakana is not evident and the valves are very short, consisting of a weak dorsal part and a narrow saccular spine that extends beyond it, angled from a broad, semicircular base. The probable females have a long bursa that may correspond to the long diverticulum of the male vesica, the whole of it rather thickened and with a slight honeycomb pattern. There are two weak, nipple-like signa distally within it, and a slight lateral lobe at the base. The ductus is short, expanding to the ostium..
