Abstract The female of Zeuxidia mesilaueizsis is described for the first time based on a single

specimen from Mount Kinabalu, Sabah, East Malaysia.

Key words Zeuxidia mesilauensis, Nymphalidae, Morphinae, Amathusijni, Mount Kinabalu,

Borneo, endemism.

Introduction

The Morphinae Zeuxicfia HUbner, 1826 is distributed in the Oriental region and comprises nine species ranging from Burma to Sundaland and the Philjppines (Corbet & Pendlebury, 1992; D'Abrera, 1985), Zeuxidin species are typical elements of closed forest habitats and generally are found in dense fbrest understorey (Schulze & Fiedter, 1998), Both sexes of all recognised species of the genus are illustrated by D'Abrera (1985), except for the female of Zeuxidia meshauensts Barlow, 1971 which apparently is still unrecorded. This

species was discovered only in 1964 during an expedition by The Royal Society to Mt Kinabalu on nonhern Berneo (Sabah, Malaysia), and was described based on a single male specimen now deposited in The Natural History Museum, London (see Barlow et aL, 1971). Subsequently, additional male specimens of Z mesiZZxuensts have been eollected on Mt

Kinabalu by Japanese entomologists and members of Sabah Parks staff some of which have been illustrated by Otsuka (1988: pl. 41), The species is endemic to the island ofBorneo and so far only known from the vicinity of its type locality on Gunung Kinabalu in Sabah (Otsuka, ]988). Both Corbet & Pendlebury (1992) and Otsuka (1988) state that the female of Z mesilauensis is still unknown.

Duringjoint field work undertaken by both authors in Mt Kinabalu Park between 1993 and 1999 to recerd and monitor the local fauna (Hla'user et aL, 1997; Schulze, 1995), we collected a single female Zeuxidia specimen which was initially thought to represent Z doubleddyi Westwood, 1851. After preparation of the specimen, however, it proved to be quite distinct frorn known females of Z dbubledayi, and was found to closely match males of Z masilauensis in wing pattern. Therefbre, we regard it as belonging to this species and here describe the female of Zleusidla mesZtzxuensis fbr the first time,

Deseription of Female Zeuxidia mesiZduensts 35

postdiscal blue band narTow compared to males, mixed with white towards the anterior margin, and submarginally with two white spots in spaoes 2 and 3; the apical spot prominent, also white. Hindwing upperside without any blue pestdiscal band. Underside of both wings matching exactly the male pattern, except for the absence of blue markings near the forewing hind margin.

From the ZezLxidia species recorded frem Borneo, the female of Z mesilauensts is most similar to the female of Z doubledoyi, from which it can be best distinguished by the fbllowing characters: Forewing upperside with a postdiscal blue band continuous towards the anal margin, not dissolved into individual spots; a white apical spot well developed; underside of wings with all markings bolder; the straight postdiscal dark band on both wings contrasted with a pale line along both margins; fbrewing underside with a small, well developed eye spot in space 2; hindwing with eye spot bordering yein M, (space 6) brightly orange.

Collecting data: 1 \, Borneo (Malaysia), Sabah, Mt Kinbalu Park, Park Headquarters, 1,2oo-1,5oo m, 6. IV. 1994, deposited in SMNS. The specimen was netted at daytime flying close to the ground in the forest understorey near a smal1 stream.

Discussion

The habitat of Zbitxidia species in are understorey sites of closed forests, where they 'especially general can be abundant along streams (Schulze & Fiedler, 1998). While the vertical

distribution,of the other three species of Zbuxidia on Mount Kinqbalu ranges from the lowland dipterocarp to the lower montane fbrest (soe Hla'user et aL, 1997), Z mesilauensis seems tb be restricted to the lower montane forest zone. So fhr, only two sites are known for the species: (1) the type locality, Mesilau plateau at an altitude of ca 1,500m, which today is 1argely destroyed through conversion into a golf course, and (2) the area around Mt Kinabalu Park Headquarters, from which the present female also originated. However, there is a high potential for a inore widespread occurrence in further mountain ranges on northern Borneo (e. g at similar altitudes in the neighbouring Crocker Rarige). Zbuxidia specimens are not frequently collected and, therefbre; it Would not be surprising when future field surveys "previous" will result in records from additional sites like in other Mt Kinal)alu endemics.
