    Default Potanthus

    #26 https://www.inaturalist.org/observations/231748488

    There are at least two individuals mixed up here.
    1 is a male.
    https://www.inaturalist.org/observations/231748488
    4 is a female.
    https://www.inaturalist.org/observations/231748488


    They all looks to be Potanthus lydia.





    #27. https://www.inaturalist.org/observations/231779903

    Potanthus lydia. Abdominal end indicate a female.


    Potanthus lydia medium FW 14-15mm.
    FW spots 4 & 5 deatched at the upper end between spots 5 & 6.
    There is always a little overlap between spots 3 & 4.
    FW spots 4 & 5 usually converging on their inner margins in a shallow ;V;.
    Underside lightly shaded with diffuse dark spots edging the band.
    Abdominal end shaded black, heavy in the male.

    Two similar species.
    Small skippers with a pointed nose marked by a dark dividing line.

    Aeromachus jhora.
    UnH with two series of defined spots.

    Default Melanitis

    #30 https://www.inaturalist.org/observations/230444429

    Most likely female Melanitis zitenius.

    The females of M. phedima & zitenius can be very similar.

    In M. zitenius the Fw costa (forward margin) is less arched & the falcate Fw apex have a longer & more acute hook.
    https://yutaka.it-n.jp/sat/40030010.html
    https://wingscales.com/Nymphalidae/M...tenius-auletes


    In M. phedima the FW costa is very arched (rounded) & the apical hook is shorter & less acute.

    Default Parnara

    #1 https://www.inaturalist.org/observations/224339719

    Parnara bada.

    P. bada is widespread, ranging from Africa to Australia.

    The UnH series of spots is often small& irregular but there is wide variation.
    https://yutaka.it-n.jp/hes/93050001.html

    Typical small spot form P. Malaysia.
    https://2.bp.blogspot.com/-r10tmE1OD...rnara+bada.jpg
    Larger spot form
    https://indiabiodiversity.org/group/.../show/15072995
    https://thaibutterflies.com/Butterfl.../parnara-bada/

    P. ganga usually have larger spots but HW spot 8 is absent or vestigial.

    https://blogger.googleusercontent.co...ara+ganga1.jpg

    P. apostata which have a small spot 6 is very dark above.
    P. Malaysia.

    Default Arhopala

    #2 https://www.inaturalist.org/observations/226120778

    Arhopala pseudomuta

    This seem quite common in Penang.

    PSEUDOMT.png

    Arhopala pseudomuta.
    FW postdiscal spot 4 shifted outwards.
    HW postdiscal spot 6 across spot 5 & cellend bar.
    Spot 7 directly above spot 6.
    HW postdiscal band widely dislocated at vein 2.

    This & A. alitaeus have more rounded spots .

    A. pseudomuta.
    https://www.butterflycircle.com/chec...1---Horace.jpg
    https://www.butterflycircle.com/chec...-%20Horace.jpg
    Arhopala alitaeus. More strongly contrasted markings.
    https://www.butterflycircle.com/chec...le_Loke_01.jpg

    The other members have spots/bands with straighter margins eg
    A. elopura.
    https://thaibutterflies.com/wp-conte...la-elopura.jpg
    A. aida.
    https://res.cloudinary.com/ppc1/imag...wku7yfpttq.jpg
    A. ariana.
    https://en.wikipedia.org/wiki/Arhopa...naMUpUnAC1.jpg




    #3 https://www.inaturalist.org/observations/226874613

    The markings are as for the amphimuta group, but the vital tornal parts are torn.
    Although it is most likely A. moolaiana it is impossible to be certain.

    Default Hesperiids

    #4 https://www.inaturalist.org/observations/226930943

    Potanthus probably P. mingo.

    You need the upperside, abdominal end & underside to id Potanthus.

    The 1st pic manage to show the abdominal end as black.
    Veins on the HW are not dark-dusted.
    3 possibilities, P. mingo, lydia & flava.
    Most likely P. mingo.



    # 5 https://www.inaturalist.org/observations/227266810

    Salanoemia fuscicornis.
    FW subapical spots hyaline.
    https://wingscales.com/Hesperiidae/S...ia-fuscicornis
    With reduced subapical spot.
    https://thaibutterflies.com/wp-conte...s-1080x719.jpg

    Salanoemia sala.
    FW subapical spots are black.

    Default Allotinus

    #6 https://www.inaturalist.org/observations/227719965
    Allotinus horsfieldi male.

    #7 https://www.inaturalist.org/observations/227719967
    Allotinus horsfieldi female. Note unusual feature ie HW spot 7 is doubled.


    Two species are very similar.
    They are still much confused.

    Allotinus horsfieldi.
    This is a common species next after A. unicolor.
    FW postdiscal band dislocated in the middle.
    HW spot 6 just under spot 7.
    All spots are variable.
    Ground colour pale biege with the spots brownish.
    Female with broad-based teeth on the HW.
    https://yutaka.it-n.jp/lyc2/80380010.html
    Males.

    Female
    https://www.flickr.com/photos/gancw1...n/photostream/

    Allotinus leogoron
    The 2nd species is very rare .
    FW band with a mid-dislocation & HW spot 6 is under spot 7.
    Male upperside with a broader brand.
    It differs mainly in that the underside ground colour is whiter & the markings darker giving it a better contrast.
    Female HW teeth slightly narrower but impossible to be certain in fieldshots.
    https://yutaka.it-n.jp/lyc2/80390001.html
    Male.
    https://inaturalist-open-data.s3.ama...55/medium.jpeg
    Female.
    https://d29tlldvxtis6c.cloudfront.ne...darkie6683.jpg

    There is much confusion.
    Otsuka's Bornean Lycaenids give good comparisons L49 & L50.

    These IDed as A. horsfieldi are probably A. leogoron.
    Males.
