Morphology

Meyrick’s original description of Exelastis phlyctaenias reads[1]:

Marasmarcha phlyctaenias, n. sp.

♂, ♀. 16-20 mm. Head ochreous-whitish, face and crown somewhat infuscated. Palpi moderately long, slender, ochreous-whitish, terminal joint with dark fuscous lateral line. Antennae light greyish-ochreous, ciliations in ♂ 1/4. Thorax ochreous-whitish finely sprinkled with fuscous. Abdomen ochreous-whitish, with indications of pale brownish-ochreous stripes. Forewings cleft from 3/5, segments acute, first moderate, second narrower (but much less narrow than in atomosa); whitish-ochreous, tinged with fuscous except towards dorsum anteriorly, more infuscated on posterior half, sometimes with a few scattered dark fuscous scales; three more or less marked cloudy roundish discal spots of dark fuscous irroration, viz., towards dorsum at 1/4, towards costa at 1/3, and before cleft: cilia pale whitish-ochreous, grey on outer 2/3, beneath apex of each segment with an irregular blackish scale-tooth, above apex of second with a short blackish subbasal line, on lower margin of first segment with three blackish specks, on dorsum with several irregular undefined groups of black specks. Hindwings with segments slender, acute ; dark grey; cilia pale ochreous-grey, on dorsum with a series of scattered black scales from base to beyond middle.

Puttalam and Trincomali, Ceylon (Pole, Fletcher); N. Coorg, 3,500 feet (Newcome); from October to December, seven specimens. Closely allied to atomosa, but readily distinguished by the different colour and considerably broader segments of forewings. It has however hitherto been confused with atomosa, and most records of that species from Ceylon are probably referable to phlyctaenias, but I have a specimen of atomosa from Peradeniya.

Walsingham’s original description of Aciptilia atomosa reads[2]:

216. ACIPTILIA ATOMOSA, n. sp.

Bombay.

Head, thorax, palpi, and antennae dull fawn-colour, the latter with a slender dark fuscous streak along their upper side towards the base.

Fore wings dull fawn-colour, sprinkled with dark fuscous scales except along the costal portion of the wing. The anterior lobe has three dark fuscous spots on its costal margin at the base of the fringes, the first at about one third of its length from the base of the cleft; the other two closely approximate to each other about half way between the first and the apex of the wing. The fringes are very slightly paler than the wings, and are thickly speckled with dark fuscous dots beneath the apical portion of the anterior lobe and on both sides of the apex of the posterior lobe. In the fringes on the dorsal margin about the middle is a group of dark fuscous spots.

Hind wings pale fawn-brown, cleft to more than half their length, between the first and second lobes. On the dorsal margin of the third lobe is a row of dark fuscous dots along the middle of the fringes. Abdomen dull fawn-colour, with scarcely paler inconspicuous bands at the junction of the segments. Legs dull fawn-colour, with paler spurs; along the underside of each spur runs a dark fuscous line, and on the two anterior pairs of legs these lines are continued along the whole length of the legs themselves.

Expanse 20 millim.

Rose and Pooni[3] discuss the relationship between phlyctaenias and atomosa and conclude these are separate species. They describe and illustrate the genitalia. The genitalia presented for female phlyctaenias do not match those of the Australian specimen dissected by Arenberger. The Indian materials lack the "paired horn" signa typical of several Exelastis species, whereas the Australian specimen clearly has such signa.

Gielis[4] illustrates the genitalia as matching the Australian specimen.
