兩個可能變更的學名 / Possible taxon change in the checklist of Taiwan

  1. 扶桑蜻蜓
    .
    Orthetrum japonicum internum McLachlan, 1894
    => Orthetrum internum McLachlan, 1894
    .
    根據苅部治紀 (KARUBE Haruki) 等人於2012年發表的研究(*1),日本就把這隻蜻蜓從 O. japonicum internum 亞種升格成 O. internum 「種」。連中國今年最新的出版的「中国蜻蜓大图鉴」(*2)也採用這種見解。「臺灣生物多樣性國家資訊網」雖然也引用苅部治紀等人於2012年發表的研究結果,把「無霸勾蜓」的學名從Anotogaster sieboldii (Selys, 1854) 改成 Anotogaster klossii Fraser, 1919。 但是,TaiBNET / TaiCOL 並沒有據此研究更改「扶桑蜻蜓」的學名。台灣會把它命名為扶桑蜻蜓,應該是根據他的學名 O. japonicum internum 來的,這也許是台灣學界不肯把它「升格」的原因之一。
    .
    Based on Karube et al (2012) (*1), the publications & internet dragonfly websites in Japan have been employing O. internum since. The latest Chinese publication on Odonata in China by Dr. Zhang (*2) also accepted such conclusion. It's puzzling why Taiwan's academia not. Curiously enough the same research conclusion was used to modify the taxon of Anotogaster sieboldii to Anotogaster klossi as published on website of TaiBNET/TaiCOL.(*3)
    .
    根據苅部 治紀 (KARUBE Haruki) 等人宁 2012 年所發表的研究(*1),日本就加這隻田蛜按 O. japonicum internum 亞種升格做 O. internum 「種」。連中國今年上新出版的「中国蜻蜓大图鉴」(*2) 嘛採用這款見解。「臺灣生物多樣性國家資訊網」雖然嘛引用苅部治紀等人宁咧 2012 年所發表的研究結果,加「無霸勾蜓」的學名按 Anotogaster sieboldii (Selys, 1854) 改成 Anotogaster klossii Fraser, 1919。 但是,TaiBNET / TaiCOL 並無根據這个研究來更改「扶桑蜻蜓」的學名。台灣加號作「扶桑蜻蜓」,應該是根據伊的學名 O. japonicum internum 來的,這無定著嘛是台灣學界毋肯加伊「升格」的原因之一。

  2. 灰黑蜻蜓
    .
    Orthetrum melania (Selys, 1883)
    => Orthetrum melania continentale Sasamoto & Futahashi, 2013
    .
    從 iNat 上的觀察紀錄來看,日本的 O. melania 比台灣的好認,比較有特色。青木先生去年夏天在通信中告訴我 O. melania 有四個亞種,其中三個在日本;在台灣、中国和朝鮮半島是另一個亞種 ssp. continentale。(但是「中国蜻蜓大图鉴」的記載是「异色灰蜻 Orthetrum melania melania (Selys, 1883)」) 原來台灣與日本的「灰黑蜻蜓」是不同亞種,所以看起來不太一樣。
    .
    (還有一個亞種在越南北部,ssp. superbum (*6 )。但是這五個亞種的學名都還沒有新增到 iNat 的資料庫中。)
    .
    One can easily find that O. melania in Japan are more distinctive than those in Taiwan on iNat. I was told, "species O. melamia is divided into four subspecies, i.e. melania melania, m. continentale, m. ryukyuense, and m. yaeyamense. Spp. continentale is distributed in Taiwan, Korea Peninsular and China, not in Japan.(*4)" by Mr. AOKI Takashi in the email correspondence last May (2018). Mr. AOKI subsequently rewrote his website and added to his Japanese checklist with 2 southern ssp. and modified O. melania into O. m. melania.(*5). Later on, I learnt there are 5 ssp., O. m. superbum distributes in northern Vietnam. The taxa of all these 5 ssp. have yet to be added to the iNat database.
    .
    自 iNat 的觀察紀錄來看,日本的 O. melania 比台灣的好認,較有特色。青木先生舊年熱人宁咧通信中加我講 O. melania 有四个亞種,其中三个宁咧日本;毋過宁台灣、中国偕朝鮮半島是另外一个亞種 ssp. continentale。(「中国蜻蜓大图鉴」的記載是「异色灰蜻 Orthetrum melania melania (Selys, 1883)」) 原來台灣偕日本的「灰黑蜻蜓」是無仝款的亞種,所以看起來無相siang (相同)。
    .
    (猶有一个亞種宁越南北部,ssp. superbum (*6 )。毋過這五个亞種的學名朗猶未收入 iNat 的資料庫裡。)

可能只是沒人修改蜻蛉目的臺灣物種名錄而已,我只改鞘翅目的。

The researches cited were published in 2012 & 2013, but these 2 taxa remained the same in Taiwan's latest 2016 publication by Lin & Yang* (which also upholds "A. sieboldii", rather than "A. Klossi".)

"O. japonicum internum" was promoted to "O. internum" based on DNA evidence, and the research was published in 2012. Since it's science, I incline to embracing the new-found fact and favor the promoted one. But I wish to know your opinion on this. Should we still stick to the checklist or take the initiative id the species as "O. internum" here on iNat? PLS let me know your opinion.

Follow the checklist, O. japonicum internum.
O. internum as DNA evidence supported.
Leave it as the uer identifies it, and both are considered good.

I may say that further contact with the professionals in Taiwan is needed, about the exact reason why they didn't make the promotion. Before changes happen here. @aru

@aru I'm sorry for my late reply, I'm rather busy these days. Can you send me "Karube, H., R. Futahashi, A. Sasamoto & Itsuro Kawashima, 2012. Taxonomic revision of Japanese odonate species, based on nuclear and mitochondrial gene genealogies and morphological comparison with allied species. Part 1. Tombo Fukui, 54: 75-106." if you have pdf? I can check.

I do not have that report though it's cited in some I read about. For example, I read one in Aug, it goes, "Species complexes in the genus Orthetrum have been uncovered by DNA sequence analyses. Based on molecular phylogeny and morphological characteristics, Orthetrum internum McLachlan, 1894 (previously regarded as O. japonicum internum McLachlan, 1894) is resolved as a genuine/distinct species from O. japonicum japonicum (Uhler, 1858) "*1 by Yong et al.

As mentioned in the post, the latest Chinese publication also stated it as O. internum.*2 So are many Japanese publications and websites.*3 In fact, I just found one Taiwanese website made such a change already. http://gaga.biodiv.tw/new23/9404/a19.htm

The reason I inquired this is to decide the "style" of the project. Should the Project be conservative or a bit proactive. Should the Project just play a role of followers of authorities in Taiwan or it should act a bit more progressive. The Proj. TDD is not in academia, I kinda of thinking perhaps the Proj. may usher in new findings, offering something different or new based on scientific researches, rather than novelty or desire of attention-getting. Then the changes to these 2 taxa coming to my attn. Perhaps, we can take the initiative on iNat about Odonata in Taiwan, though still a follower in the scientific world.

Since this project is no longer a one-man show after 3 were inducted as managers & curators. So, I would like to know your opinions.

In my opinion, I need to check the original publication (not Yong et al., 2013). Because they just cited the paper but didn't include this species in their analysis.
