    Default Curetis sperthis. Possibly still extant.

    Two decades ago, the late Sunny Chir have an intriguing pic of a female Curetis that is marked as in C. saronis but seem to be marked with dark specks.
    Unfortunately I have not been able to trace this although I think I kept a shot of it.

    A recent observation seem remarkably similar .
    https://www.inaturalist.org/observations/256536296
    Correction: This image is actually male..
    The FW band is sort of bent slightly to be parallel to the margin.
    The black dotd are rather sparse but those at the bases of FW space 1b, 2-5 looks similar.
    These black dots can be sparse in some cases.
    eg below.
    https://www.gbif.org/occurrence/2847199185

    In comparison C. saronis have a relatively clean look.

    This observation is almost certain to be a male Curetis sperthis.
    It have the following characters.
    1. The ground is finely speckled with black dots.
    2. The FW band is set very close and mostly parallel to the margin.
    3The HW postdiscal spots 6 & 7 are in line; likewise submarginal spots 6 & 7 are in line.

    Compare with a standard C. sperthis male below it is a very good match.

    Added.
    1.This looks to be a female C. sperthis.
    The markings are that of the bulis group.
    The FW band is parallel to the margin and the ground appeared speckled.

    2. Male C. sperthis.

    Default The thetis group.

    The thetis group comprise three species, C. saronis, tagalica and regula.

    The species have a clear ground with lunulate postdiscal spots that runs parallel to the FW margin. Their patterns can merge into one another and can be very confusing.
    All three species were recorded in Singapore .
    The first two species are probably still extant.
    CURETIC.png

    Curetis saronis.

    Saronis :Greek Goddess Artemis was provided a sanctuary by King saron. In doing so she also acquired the surname Saronis.

    This is the most frequently seen species.
    UnH with postdiscal spot 6 basad (shifted inwards towards base)of spot 7, and just clear of spot 5.
    Lunules (striae) usually poorly shaded.
    Legs banded red/orange or red-brown.
    Female orange patch square-ended.

    Curetis tagalica.

    Tagalica. Latinised, the Tagala region of the Philippines.

    Unh postdiscal spot 6 is basad of spot 7 and well clear of spot 5.
    Spots typically moderately shaded, heavy in some regions eg Borneo.
    Legs banded black or dark brown (Fleming.).
    Male HW shaded brown inner margin.
    Female FW orange patch elliptic.

    Thailand.

    There is great variations in the indentation of the HW band and the leg colouration.
    There were past observations of individuals with black or grey banded legs.
    C. saronis also have forms with very dark redbrown bands.
    It is possible that crossing have results a lot of confusing forms.
    Probably C. tagalica.
    https://blogger.googleusercontent.co...eam2-FedHo.jpg
    Very likely.

    Curetis regula.

    regula ; regular ,refering to the band being much less crooked.

    UnH postdiscal spot 6 usually level with spot 7 and just clear of spot 5.
    Spots often heavily shaded giving a continuous appearance.
    Female FW orange elliptic.

    There is no observation to suggest that C. regula is still extant in Singapore.
