Cyana sp. 4802  

Cyana sp. 4802
(x 1.73)

A single male of a species similar to pudens or luzonica Wileman & South was taken by S.J. Willott in the understorey of primary lowland forest at 170m near the Danum Valley Field Centre in Sabah. It is larger (11mm) than pudens and has paler red almost straight fasciae that meet the dorsum at right-angles; the costa is a similar red. There is also a more orange-red marginal band, the inner border of which is undulating but not dentate. The discal dots are dark brown-black, three in number, the most dorsal being more of a streak, set on CuA approximately behind the more distal of the two costal dots. The secondary sexual scaling is on the underside only, consisting of a round patch just basal to the postmedial, distal to which there is a constriction, then a ridge running distad to converge with the costa. The tuft of scales on the upperside of pudens in the same position as the round one is absent from this species. The hindwings are white. C. luzonica has somewhat more oblique fasciae and, of the three black discal spots of the male, it is the more basal that is developed into a streak. The secondary sexual characters of luzonica are as in pudens. C. metaleuca Hampson (Java, Bali) is similar to luzonica in facies except the more distal two discal spots are set more obliquely, and the basal one is less extensively elongated and does not recur in the female. In both luzonica and metaleuca there is a blackish streak associated with the scale tuft and groove extending distally from the postmedial near the costa, and the underside of the forewing is extensively reddened.

The genitalia of the Bornean male are similar to those of luzonica and metaleuca (illustrated by Roepke [1946a]), and have fields of coarse scobination in the aedeagus vesica with clumps of longer spines not seen in pudens, but there are three of these clumps in the Bornean male and only one in the other two species.

However, whilst it is evidently distinct from the species already named, further material of this species, including females, is needed to ensure it is indeed new to this rather complex genus.
