    Dear Dr Seow,

    Requesting ID and clarifications regarding some Skipper shots of the Tribe Baorini from across my butterfly-photography journey!

    1. Borbo cinnara?

    2. Borbo cinnara? To differentiate Borbo from Parnara, do we look at the FW subapical spot 8 (absent in local Parnara?) and arrangement of HW spots?

    3. Not too sure about this one.

    4. Baoris sp. maybe Baoris oceia?

    5. Caltoris sp. or Baoris sp.? This one seems to have faint HW spots which I've never seen before in Caltoris!

    6. Just wanted to confirm if this is Potanthus ganda! My saturation levels are in the negatives and yet it is still so orange!

    I apologize for the quality of some of the photos as they were taken with my old lens when I was just starting out! Thank you so much in advance!

    Cheers,
    Lumin Ong

    In terribly worn individual the subapical spots may be a help.

    Parnara .
    FW subapical spots 6 & 7 with their margins aligned. The upper spot 8 shifted out or also aligned with spot 6 & 7.
    P. ganga.

    Borbo cinnara.
    All three subapicalspots in an arc or upper spots 7 8 more aligned.

    Pelopidas mathias/agna
    FW subapical spots 7 7 8 with their margins aligned. Spot 6 shifted out.

    1. FW subapical spots eveenly separated; Greenish body hairs; antennal clubs thick.
    Likely Borbo cinnara.

    2. Borbo cinnata.
    No hW cellspot; thick antennal club ;fW subapical spots 7 8 in line.

    3. Pelopidas agna female.
    FW spots 6 & 7well separated. This indicate if spot 8 is present it will be close to spot 7 (as in Pelopidas)
    There appear to be a faint white cellspot in the correct position.

    4. Uniform dark brown ;antennae black suggest Baoris probably B. oceia.

    5. Unknown
    Fw spots suggest or baoris.
    The reddish brown colour exclude Borbo or Pelopidas or Parnara.
    HW "vague spots" do not match any species.

    6. Female Potanthus ganda.
    Potanthus ganda is normally stated to be quite reddish.
    The Singapore population is likely to be mixed & variable.
    typical male.
    https://www.inaturalist.org/observations/16026310


    7. Parnara probably P. bada.
    Note FW subapical spots 6 & 7 in line, spot 8 is missing; thick antennal club.
    HW with irregular spotting.

    Re4vision

    https://www.inaturalist.org/observations/178335953
    Post 41, 5.Pelopidas spp.

    The three well-spaced HW spots are as in this example of female Pelopidas agna.
    The three large HW spots are spot 2, 4, & 6.
    The three small spots are spot 3, 5, & 7.
    https://www.inaturalist.org/observations/178388163

    The HW cellspot is missing, but this does occasionally happens.
    Below, note the male from Ranong lack HW cellspot.

    Dear Dr Seow,

    Requesting ID for these two skippers!

    1. Potanthus trachala tytleri? FW spots 4 and 5 touching only the spikes of the adjacent spots + abdominal end black-banded. So unfortunate a Crab Spider got it before I did

    2. Baoris sp. maybe Baoris oceia male? Shot by JX.

    Post 46.

    1. This is a typical male Potanthus trachala.
    Abdominal end banded black; FW spots 4 & 5 without overlap from the others.
    Note HW band upper spot (actually in space 4 & 5) strongly shifted outwards.


    2 Baoris likely B. oceia .
    If abdomen is noticeably banded, it is a plus feature.

    Dear Dr Seow,

    Hope you've been well! Requesting ID for this skipper found in Sungei Buloh. It has white-tipped antennae so I assume I can rule out most of the local swifts such as Caltoris and Baoris. All photos are of the same individual shot by JX and I.

    Might this be Hyarotis microsticta (please correct me if it has been revised to H.microstictum!)?

    Thank you in advance!

    Cheers,

    Yes. This is Hyarotis microsticta.

    All scientific names are written in Latin.
    Latin have gender specific endings whether in noun or adjective.
    The earlier European naturalists all studied Latin

    Hyarotis is the ancient Greek name of a river in the Punjab ( now Ravi river.)

    microsticta means small spots.... female gender.
    microstictus is the male gender form.
    microstictum is the plural neutral gender form.

    This species was named first as Isoteinon microstictum by Wood-mason et al.
    Not sure what Isoteinon meant.

    When it was transferred to Hyarotis it was named as Hyarotis microsticta.
    To be grammatically correct the gender of the describing adjective must match the noun.

    Since Hyarotis is regarded in the male gender, the correct adjective should be microstictus.

    I am simply following C&P4 in retaining the name as Hyarotis microsticta.
    ( Hyarotis' gender was probably uncertain then ,& thought to be female.)

    Japanese entomologists who now do extensive studies do not have Latin; they simply use the first written taxonomic name without considering the gender change.
    Thus they put this down as Hyarotis microstictum.
    https://yutaka.it-n.jp/hes/91840001.html

    Here is the grammatically correct name placed at the top.
