係唔係都係在沙螺灣公廁影的?
作者: dick    時間: 2006-10-9 00:08

呢d靚好多!
係咪公廁又暗又濕又安全, 而且晚上又有燈, 所以d蛾比較喜歡呢?

Yes~
不妨順道去參觀一下~

我日頭去過, 得d毛蠓.
唔怪得方sir話異性廁所比較多野睇

#1 is a species of Acentropinae (=Nymphulinae), within Crambidae. Not sure of the genus and I'm pretty sure I've not seen this one before for HK. The larvae of species in this subfamily are aquatic - I would guess that you were within 50m of the main stream at Sha Lo Wan?

#2 is Glyphodes bicolor (Crambidae, Spilomelinae) - common and widespread in HK.

cheers,

Roger.

Thanks~Roger

#3. Endotricha theonalis

Endotricha theonalis - but a little worn and somewhat suffused. Unfortunately the amount of variation within some of the Endotricha species in Hong Kong makes this a difficult genus - theonalis  is one of the easier ones!

cheers,

Roger.

Update on #1

I've received a reply from Yen Shen Horn, who is a specialist on the Acentropinae.

He said:

"good...its an Eristena feeding on littoral algae of mangrove"

cheers for now,

Roger.

Thanks again~!!

is look like this??→ http://www.jpmoth.org/Crambidae/ ... tena_argentata.html

Quite close, but not the same species - there are differences in the maculation that are apparent on the visible components of both fore and hind wings. One really needs set specimens for comparison of similar species, as is the case in this genus. If the Lantau species turns out to be new, then I'd have to look for specimens to base the species description on - the photo is insufficient as most characteristic features are associated with the genitalia.

cheers,

Roger.

#1 could be the Eristena argentata Yoshiyasu.    Genitalia (specimen) is required for confirmation.    If the ID is affirmed, it would be the first record from the whole of China.   Congratulation Mao!
作者: hkmoths    時間: 2006-10-11 11:37

Rats!!

I have a problem with some of the images not downloading at the moment. I was going to point out the differences in fasicae and maculation between Eristena argentata and the indiviual of Eristena sp. from Lantau - Nadia, I am not convinced that they are the same species, although they are definitely closely allied. Yen Shen-horn is sending students to work on this subject shortly (permit applications in progress!)

By the way - no preposition is needed when referring to a scientific name.

Does anyone know if the species in Li et al., 2003 (尤平, 李后魂, 王淑霞) are illustrated anywhere, and if so are these species (except E. bifurcalis, which is already known from HK) more likely to represent the Lantau species?

cheers,

Roger.

The paper on Eristena is by You et.al., 2003 instead of Li et al., 2003.  

The illustrations of the the two new species are attached here with due credit given to the authors.   The Eristena from Lantau is not among the known Eristena spp. from China.

Hi Nadia,

Many thanks for posting the two species described in You et al. (please forgive the incorrect order I used - I don't know many Chinese characters - I do know the characters for Li and Wang, but will have to try and remember You for future reference). Incidentally, Prof. Li attended the recent 1st South East Asian Lepidoptera Conservation Symposium held by Kadoorie Farm & Botanic Garden. He has helped with some species identifications already from my thesis (and subsequent) collection, and has taken some voucher material to work on back in Tianjin - mostly Gelechiidae and Oecophoridae. We will be doing a few joint papers over the next year or so to list the HK species, including several currently undescribed.

As to the Eristena - the most obvious difference appears to be the medial fascia on the forewing, which is virtually continuous and heavily shadowed in the Lantau specimen, whereas the Japanese specimens illustrated on the internet of E. argentata have the medial fascia broken into three sections with very little shadowing; the apical side of the post-medial strigula is not lined on the Lantau specimen (and the strigula appears broader). There are subtle differences on the abdominal banding as well. As we both noted, a specimen will be needed to confirm, via its genitalia, the actual identity of the Lantau species.

cheers,

Roger.

This is a different subfamily!

Cymoriza sp. nr. albiflavidalis

Crambidae, Musotiminae

cheers,

Roger.

It could be C. hoenei Caradja, 1933. The specie's type locality is Guangdong, Luofu Mt.

I didn't see any figures about albiflavidalis, could you provide some to me? Thank you!
作者: fool12345    時間: 2007-4-12 11:37

To: 貓魔鈴 老兄
Could you send me some specimens of the Eristena sp. in your photo. I am now doing some research on Acentropinae, Schoenobiinae and Musotiminae. I can afford the cost.

sorry, mao just took a photo, haven't took any specimens with this.

It indeed very similar with Eristena argentata, which is not recorded in China now.
That's a figure from a Japan Web.

original description of E. argentata available online at
http://ci.nii.ac.jp/els/11000337 ... =1305860652&cp=

I now have four specimens from Hoi Ha Wan, where the species appears common. Will compare and dissect in due course, but there are four h/w eyespots on the tornus and subtle differences in (especially) the medial and postmedial f/w areas.

cheers,
Roger.
