Material examined.

Holotype: ♀, with labels: "Holo- | type" [round label, red ringed]; "Batchian [Bacan islands] | Mar[ch]. 1892 | W. Doherty"; "Pyrocrambia | ocellata | type ♀. H[a]mps[o]n." [handwritten]; "♀ | Pyralidae | Brit[ish].Mus[eum]. | Slide N°. | 20258"; " NHMUK 010923358" [barcode appended]. Deposited in NHMUK.

Diagnosis.

The large oblique elliptic white patch at base of the forewing, the median trapezoid and postmedian semi-elliptic tawny patches are unique to H. ocellata . In female genitalia, the long, wrinkled and multicoiled ductus bursae, the ovoid corpus bursae bearing long acanthae, and the long glabrous thorn unequivocally segregates H. ocellata from other Hoploscopa species. Male unknown.
