    Default Malay Hesperiidae for ID

    Some confusing Hesperiidae, all from Malaysia, observed Feb.-March 2019.
    I think 1, 2 and maybe 3 could be Potanthus.
    4 and 5 Telicota?

    1. Kuala Selangor

    4. Kuala Tahan

    5. Cameron Highlands

    #1. Potanthus sp. Uncertain . Since FW spot 8 is reduced in size could be P. juno.

    2; Potanthus juno: FW spot 8 absent (ie only 2 subapical spots) ; Abdominal end black ;often FW spot 5 is smaller than spot 4 but not here.

    A female P. juno.Note FW subapical 8 absent (may be vestigial) spot 5 smaller than spot 4;

    3. Ampittia dioscorides.

    4. Female Telicota colon ;Note spot 4 detached from spot 3 ; spot 4 & 5 not fully overlapping; HW no spot 7 (both sides) All Potanthus should have spot 7.

    5. Potanthus lydia The inner margins of spots 4 & 5 forms a characteristic 'V'.

    Thank you very much dr. Seow.

    A couple of other Hesperiidae, this time from Vietnam.
    All were shot in Baoloc, Central Highlands, Alt. approx. 800m, Dec. 2018

    - No.1 and no.2 might be Potanthus Lydia: FW V-shaped inner margins spot 4,5
    - No.3, 4 and 5: Taractrocera archias?
    - No. 6: Potanthus sp.?

    No.1

    Potanthus are very difficult without both upperside & undersides.
    There are far more species in Vietnam.

    1. More orange; HW veins not darkened. Probably P. ganda.

    2. Yellower; HW veins not darkened; abdominal end dark. Probaly P. mingo
    http://yutaka.it-n.jp/hes/92810010.html

    3 , 4, & 5. Taractrocera archias ;antennal club without apiculus (tip) HW with hockeystick mark.

    6 HW veins not dark ;FW band without overlap to subapical spots; HW band's outer spot just shifted out a little.
    Probably P. nesta.
