Specimens examined.

MALAYSIA: SABAH: British North Borneo, Tenompok, 10-14.II.1959, T. C. Maa, collector (3 ♀, BPBM); British North Borneo, Tenompok, 1460 m, Jesselton, 48 km E., 26-31.I.1959, T. C. Maa, collector (1 ♀, BPBM); North Borneo, Ranau, 22-25.II.1959, T. C. Maa, collector (1 ♂, BPBM).

Discussion.

The male has not been described. It is black with the apex of the fore- and midfemora, fore- and midtibiae and tarsi, and the basal half of the hind tibia white. The lancet was illustrated by Wong (1977: fig. 15). Benson (1963) and Wong (1977) distinguished it from all other Oriental Pristiphora by its linear malar space, but Pristiphora ettera has a similar malar space and Pristiphora annetna and Pristiphora inthanoni approach it. Wong (1977) placed it in his Pristiphora chlorea complex, near Pristiphora fausta (Hartig). The male genitalia are illustrated here ( Figs 26, 27 ) and do not have the curved valvispina typical of the chlorea complex. The genitalia are unusual among Pristiphora because of the unusually long, straight valvispina and the extremely broad gonocardo. Pristiphora fausta also has a long valvispina ( Wong 1977: fig.7), but it is curved at its apex. I have not seen such a broad gonocardo in other Pristiphora species, but this is not usually illustrated by authors who illustrate the male genitalia. The additional records are close to the type locality. The species was described from one female from "North Borneo: Mt. Kinabala, Maru Parei, 5,000 ft., 27 April 1929, H. M. Pendlebury" ( Forsius 1933).
