    1. Parnara bada. Note also short antenna with thick club.

    2. Polytremis lubricans. Note colour & shape of HW spot 4.

    3. Probably Pe;opidas conjunctus male. Variant with reduced spots.
    There is a HW cellspot; in the correct spot ,so can not be an artifact ie injury mark, etc.
    Deep brown colour suggest P. conjunctus.

    4.Uncertain. The shape is as in Caltoris philippina but the colour is wrong & there is an upper cellspot.
    C. philippina male.

    Could it be another Caltoris. No other have this narrow shape.

    Could it be Baoris . Never seen one so distorted.
    Baoris farri male.

    5. Probaly Caltoris bromus female.
    C. cormasa always have the subapical spots small.
    FW & HW of the same colour tone.
    Female C. bromus.

    Dear Doctor Seow,

    I kindly request this identification for what i suspect is Zographetus species, Zographetus ogygia. The photo credit goes to Nicholas, with his remarkable and outstanding photography.

    When it becomes very worn as here the appearance can be confusing.
    Although the HW have a reddish tone the overall markings are closer to Z. doxus.
    I would put it this is more likely to be Z. doxus male.

    Z. doxus generally ochreous although it can be reddish.
    HW with a yellow discal area.
    HW brown border more defined.
    Veins in the outer zone strongly darken.
    Reddish males.

    Z. ogygia.
    HYW more uniform redbrown to golden brown.
    Veins hardly darken.
    No yellow area, & brown border diffuse.

    Dear Doctor Seow,
    I was scrolling through forums and was reading the ID features for amathusia species, would this, based on the notched 4th brown bae in between the veins, be a bicolor palm king?

    Yes. This would be Amathusia friderici.
    Since it feeds on the common oil palm it is not rare in P. Ubin.

    The other species of Amathusia are very similar & difficult to separate..

    A. binghami looks very similar ,the median band is broad & more reddish. The upperside with more dusky orange markings.
    https://www.pbase.com/lcgoh/image/155684525

    A. masina is deep reddish brown ,the paler postdiscal band is also solid, without a colour break in the middle of the band.
    https://inaturalist-open-data.s3.ama...9390/large.jpg


    Amathusia perakana have the HW 4th band often completely broken , with separated spots.
    In addition the male have sharper FWs.
    Males.

    https://thaibutterflies.com/wp-conte...a-perakana.jpg

    The recent observation from Kent Ridge is definitely not A. phidippus.
    https://static.inaturalist.org/photo...502/large.jpeg
    It looks like a female A. perakana.
    The FW is not sharp as in the male.
    However, there are examples of A friderici from Ubin having the HW 4th band very narrow & broken.
    So it is uncertain whether this is A.perakana or friderici.

    Dear Doctor Seow,

    i was looking through inat and i realise there are two species of white tipped skipper,Erionota hiraca and Erionota acroleuca. Do you know what are the differences or why is there a species shift which i may have missed out?

    As often in taxonomy there are a lot of shifts & turns, & this one have a fair bit.

    1881 Wood-Mason & De Niceville described taxon acroleucus from the Andamans.

    In the same year (1881) Moore also described a male as hiraca from the Andamans.

    de Jong & Treadaway in 1992 thought Moore', name have priority, but this was later proven wrong by later researchers.

    Thus the correct name would have been Erionota acrolueca (gender shift to feminine gender).Synonym hiraca.


    Semper described taxon apex from Luzon, Philippines in 1892.
    This was considered a subspecies of acroleuca.
    This taxon apex was applied to all the forms in SE Asia.
    Evans described taxon apicalis from Bassein ,Myanmar in 1932, & this name falls as a synonym of apex.

    de Jong & Treadaway 1992 judged taxon apex to be distinct & different from the mainland population, elevating it to a new species.

    The population in SE Asia is given the next available name ,ie Evans' apicalis.
    Thus the population from SE Asia becomes Erionota acroleuca apicalis.


    Some researchers also suggest the mainland population (taxon apicalis ) is different from that in the Andamans (taxon acroleuca.).
    Thus the current situation if verified by DNA analysis.

    1. Erionota acroleuca (= hiraca ). Andamans.
    Note HW patch is very broad.

    2. Erionota apicalis SE. Asia including NE India.
    http://yutaka.it-n.jp/hes/92340010.html
    As E. apex following Evans' 1946 revision.
    https://www.ifoundbutterflies.org/si...abb545-1_0.jpg
    Cambodia.
    https://inaturalist-open-data.s3.ama...113/medium.jpg


    3. Erionota apex. Phillipines.



    Currently here, this is best left as Erionota acroleuca apicalis unless later research into genetics prove otherwise.


    TL Seow:Cheers.
    PS. Note taxon = taxonomic name.
