Not 100% sure on this one.

Most likely Macroglossum variegatum, though there are several other possibilities. Will follow up with a couple of specialists, but if a ventral shot were available, this would make life a little easier. A specimen would settle the issue, but I don't condone taking [i.e. a voucher specimen] every individual Macroglossum to find out what species it is, even if it's a difficult group and one has a collecting permit from AFCD!

cheers,

Roger.

It looks like a Macroglossum heliophila to me.

Hi Nadia et al.,

I don't think this is M. heliophila as the dark medial band on the forewing turns basally where it meets the dorsum (trailing edge), both on the inner and outer edge of the band, which is typical of M. variegatum. Also the dark abdominal segment two segments up from the tail fan is typical of M. variegatum.

I have attached a photo showing specimens of M. heliophila (left; 5) and M. variegatum (right; 15) for comparative purposes - it is taken from one of the plates in my forthcoming book. - the scale bar is for reference (CMY-RGB and each colour section is 1/6th of an inch, the b/w sections are in mm, the whole bar is 1 inch / 25mm and will not appear on the final plates! I should add that these specimens were collected under a permit issued by AFCD for my PhD fieldwork.

cheers,

Roger.

BUT . . .

I haven't yet ruled out Macroglossum pyrrhosticta, which is also very similar to M. variegatum (virtually identical forewing pattern) - I am a little suspicious of the thoracic pattern, this doesn't quite match variegatum, so I need to check out pyrrhosticta.

cheers,

Roger.

回覆 #8 hkmoths 的帖子

My reply in 6 is assuming #5 is definitely correct.   Honestly I'm more comfortable if the species is Macroglossum heliophila.   'pyrrhosticta ?'   ............   not quite likely.     Unfortuntely I can't afford the time and opportunity to do the genital study.    You're our only hope now!

Hi Nadia & lamchoping,

I've checked out M. pyrrhosticta on Tony Pittaway's site (http://tpittaway.tripod.com/china/m_pyr.htm) and the abdominal band, as well as the wing fasciation are a good match, making this the most likely species. The thoracic patterning also matches the female specimen illustrated by Pittaway (and the broad tail fan in the photo of the specimen posted by lamchoping also suggests a female). Without dis-secting the genitalia it's really not possible to be 100% certain if it's M. pyrrhosticta or M. variegatum, though I have to reiterate that it is not M. heliophila, for the reasons I've pointed out in post #5. There is one other character that would help make a final decision, but that is the colour on the ventral side of the tail fan - as pointed out by Tennent in 1992 who noted the ventral side  of the tail fan was chestnut in fresh specimens of M. pyrrhosticta, not dark brown. Unfortunately, this is not a feature that is visible!

I would be reasonably confident to place this as a female Macroglossum pyrrhosticta, though a genitalia dis-section would be the only sure way of knowing.

cheers,

Roger.

probably yes, though would need to see the hindwing and ventral view to be sure that it's not M. variegatum.

sorry, no. need to see the underside of the "tail fan" - can't make out the necessary details from this view.

However, the dark sub-medial band is pretty straight, so I'd be 95% confident of this being M. pyrrhosticta

cheers,  Roger.
