Meekistrotia Bethune-Baker^{gen. n.}

Type species: meeki Bethune-Baker (New Guinea, Seram) comb. n.

This genus separates out two described species from the concept of Hyperstrotia Hampson (type species aetheria Grote, U.S.A.) as listed by Poole (1989), the second being molybdota Hampson comb. n. (N.E. Himalaya, Peninsular Malaysia) and adds two new ones from Borneo. A further Bornean species currently in Hyperstrotia (Poole, 1989), inordinata Walker, will be treated in detail in the context of the revised checklist being prepared for Part 2 of this series but is hereby transferred from Hyperstrotia to Chorsia Walker, comb. n., as its facies and male genitalia indicate it to be a member of that genus, treated in detail by Holloway (2005: 405). Hyperstrotia is unrelated, the type species having a general appearance similar to that of species of Selepa Moore (Nolidae) or Savoca Walker (Stictopterinae).

The forewing facies in Meekistrotia is variegated blackish brown on fawn or bone colour with diverse black patches. The reniform, when evident, is 8-shaped. The hindwings are dull medium brown. The male antennae are ciliate. The forewing radial sector veins are reduced to four, the first two arising close together from the cell and diverging only slightly from each other as they run to the costa, and the second two arising from a common stalk more distally and splitting at about half way,  meeting the margin on each side of the apex. The phragma lobes of the second abdominal tergite are small.

The male abdomen has the eighth segment of a highly developed framed corematous type. Both tergite and sternite are twice as long as the seventh segment. The tergite is half the width of the sternite, however, with a central bulge, a pair of apodemes anteriorly and a tongue-like process posteriorly. The sternite has a barrel-shaped frame, with a pair of triangular flaps at each end and a pair of leaf-like plates continued in a pouch within it and extending into the interior triangular structures. The seventh sternite has a central apodeme. The genitalia have a short, fusiform uncus. The tegumen extends well beyond the saccus on each side, expanding as it does so into two hair-bearing lobes. The valves are narrow, parallel-sided, narrowing further over a short apical section. They bear dense masses of fine, deciduous hairs. The aedeagus is straight, narrow, and the vesica bears a single slende cornutus distally.

The female genitalia of the type species (Fig 95) have the apodemes of the eighth segment of a normal length. The ductus bursae is moderate, simple, joining the bursa just distal to a short apendix bursae. The corpus bursae is pyriform, with small lateral and extensive distal fields of fine spicules. 

Robinson et al. (2001) recorded Hyperstrotia molybdota as feeding on Acanthaceae as a larva, the record coming from Bell (MS). However, vouchers located for this record show the species to be Ozarba molybdota Hampson (Sri Lanka, S. India).
