Sundatelia Holloway^{Gen. n.}

Type species: gentingthea sp. n.

This genus has the typical euteliine features of a curved flange associated with the apodemes of the basal abdominal sternite and an oval sclerite within the ductus ejaculatorius of the male vesica. The facies is similar to that of Atacira Swinhoe, but the doubled postmedial of the forewing is more closely associated with the submarginal, the two only enclosing a small dark block on the costa rather than the triangular mark that typifies most Atacira, and then three patches of paler ground over the rest of their length. The antemedial is darker than the medial, also double, much more prominent than in Atacira and obtusely angled centrally. The general ground colour is grey or brownish grey. The forewing reniform is formed of a grey oval with a fine black surround, with the orbicular similar but smaller and round. The hindwings are also grey, paler basally, with poorly defined, slightly darker medial and submarginal fasciae. The male antennae are densely ciliate rather than bipectinate over the basal half as in Atacira.

In the male abdomen, the eighth sternite has a semicircular band of sclerotisation anteriorly that encloses a membranous zone with setal hairs that extend posteriorly, the setal bases being enlarged in a semi‐circle just posterior to the sclerotised band. The anterior margin of the tergite is deeply concave between two rounded apodemes with a seta‐bearing membranous zone also extending posteriorly. The genitalia are characterised by strong saccular spines on the valves as in Atacira, but the cucullar part is also elongate and triangular rather than reduced. The uncus is unmodified, and the saccus is broader and shorter than in Atacira. The aedeagus vesica has one or two robust cornuti as well as fields of scobination and patches of more needle‐like spines.

The female genitalia are typical of the group with a narrow eighth segment that has short but robust apodemes and a generally scobinate, pyriform corpus bursae with a double scobinate signum in the distal part.

The genus contains three species that have so far only been recorded within Malaysia, two only within the Genting Tea Estate, as reflected in the name of the type species.
