Psaphis endoi Holloway sp. n.

Psaphis camadeva Doubleday sensu Holloway, 1976: 91, partim.

♂♀ 30mm.

The hindwing margin is more indented on the more anterior anal vein than in other Bornean species, but the facies is generally similar to that of euschemoides. However, the yellow of the hindwing is paler and less orange than in other species and is generally as extensive as that in euschemoides or more so, particularly in the female where the subapical spot is broadly contiguous with the yellow area basal to it. On the forewing the yellow antemedial and subbasal spots are smaller and separated compared to those in euschemoides, more as in scotais. In the subapical triplet of white spots, the most posterior one is diagnostically narrow and elongate; the subtornal duo are set more obliquely than in euschemoides. The white spots are generally larger in the female. On the underside, the purple iridescence amongst the distal pale spots of the forewing is more restricted to the veins and is of a darker, more turquoise tint compared to that in euschemoides and scotais. On the thorax, the tegulae are basally black as in scotais and camadeva rather than all yellow as in euschemoides. In the male abdomen, the structures of the eighth sternite are diagnostically massive, incurved, pincer-like. The uncus of the male genitalia is small, entire rather than bilobed. There is a particularly long serrated component within the valve sacculus.
