Type locality. ‘[ Indonesia, Enggano Is.,] Bua Bua’.

Distribution. Indonesia: Enggano ( GESTRO 1892), Java ( UHMANN 1929, 1931a), Sumatra ( WEISE 1911a); Malaysia: Selangor ( STEINER 2001a,b).

Host plants. Arecaceae ( KALSHOVEN 1957) ; Calamus ornatus Blume in J. J. Roemer & J.A.Schultes, Eugeissona tristis Griff. , Iguanura wallichiana (Mart.) Benth. & Hook. f. ex Becc., Oncosperma horridum (Griff.) Scheff. , Salacca sp. ( STEINER 2001a,b).

Remarks. WEISE (1911a) gave the distribution of this species as ‘ Malacca, Sumatra, Amboina’. However, it is unknown why he listed these as there was no published record of abovementioned places prior to his catalogue. The species was recently published from Malaysia ( STEINER 2001a,b) and the record for Sumatra was probably generalized and in fact refers to the type locality, Enggano Island situated about 100 km soutwest of the Sumatran coast. However, I leave Sumatra in the distribution as it is very likely found there and it might be that Weise actually studied some specimens collected on the Sumatran mainland. On the other hand, I do not adopt the record from Ambon because, if it was based on collected material, it was probably misidentified or erroneously labelled.

The occurence in Java is also uncertain according to Uhmannʼs unpublished notes in his separata as he additionally handwrote there that the record supposedly belongs either to W. palmarum or W. drescheri (see the original copy of UHMANN (1929) deposited in SDEI).
