关于 内溪蟹属 

Tiwaripotamon是由Bott(下称博特)于1970年使用蟹类分类学家Krishna Kant Tiwari名字命名的,所以台湾称为荻溪蟹(音译)。模式种是越南的安南泽蟹Geothelphusa annamensis  Balss, 1914。由于发表的比较迟,博特本人对于近溪蟹类群的研究没有深入到我们这个时代的进度,建属时博特放入了6种,但是到今天仅剩2种仍然在里面,即安南内溪蟹Tiwaripotamon annamensis  (Balss, 1914)(安南泽蟹)和蜘蛛沃玛内溪蟹Tiwaripotamon araneum (Rathbun, 1905)。

后来越南和中国学者陆续发表了一些物种,目前大部分物种都是近些年整理的。

动物志17卷发表时,戴爱云和Naiyanetr(1994)[5]发表了中国的两种内溪蟹:修仁内溪蟹Tiwaripotamon xiurenense Dai & Naiyanetr,1994和平果内溪蟹Tiwaripotamon pingguoense Dai & Naiyanetr,1994,两者全部分布于中国广西。

2001年,Yeo和Ng[4]发表了吉婆岛一新种编辑内溪蟹 Tiwaripotamon edostilus Ng & Yeo, 2001。并讨论了发表的几种内溪蟹:安南内溪蟹Tiwaripotamon annamense (Balss, 1914)和蜘蛛内溪蟹Tiwaripotamon araneum (Rathbun, 1905)在越南的分布。

2002年越南学者[7]发表了一种越南泽蟹Geothelphusa vietnamicum Dang & Ho, 2002,后被重新归为内溪蟹(2007、2012),称越南内溪蟹Tiwaripotamon vietnamicum (Dang & Ho, 2002)。

2014年,施习德和越南学者[6]发表了渭川内溪蟹Tiwaripotamon vixuyenense Shih & Do, 2014。

2016黄超,施习德等人[3]发表了中越边境的梅雨内溪蟹 Tiwaripotamon pluviosum Do, Shih & Huang, 2016。

2017年,越南学者又发表两种新的内溪蟹[8]:春山内溪蟹Tiwaripotamon xuanson Do, Nguyen, Dang,2017和咸安内溪蟹 Tiwaripotamon hamyen Do, Nguyen, Dang,2017

2020年,学界大牛Sameer.K.Pati、Darren.C.J.Yeo和Peter.K.L.Ng发表了一新单种属奎氏溪蟹属Krishnamon Pati,Yeo & Ng,2020[1],用于安置唯一在印度的奥氏内溪蟹*Tiwaripotamon austenianum (Wood-Mason, 1871)。所有的内溪蟹种类都被确定范围,仅分布在越南北部-中国的狭长地带里。

至此,到2020年3月10日,内溪蟹包括了10种。

以及

奎氏溪蟹属Krishnamon Pati,Yeo & Ng,2020(1种)

属名致敬Krishna Kant Tiwari,和内溪蟹的属名是一个来源同一个人。(我觉得下次是不是应该来个Kant溪蟹属···)

1奥氏奎氏溪蟹*Krishnamon austenianum (Wood-Mason, 1871)

种名无法找到意思,借用其他类群的种名可能存在的来自于姓氏* Austen。也可能是为南方的?

该类群还有一些看起来极度相似的种类,通常分布在泰国。

同氏塔普溪蟹Thampramon tonvuthi Ng & Vidthayanon,2013[2]

属名指代山洞Tham Pra 。种名致敬Mr. Pituk Tonevuth,泰国的一位社区领袖,他保护免受采石场特许权影响石灰岩地区(喀斯特地貌)生态,他现在成功地将整个Tham Pra所在的卡斯特地区作为Thung Salaeng Luang国家公园的一部分加以保护。

纤足菲氏溪蟹Phaibulamon stilipes Ng,1992 [10]

属名致敬Ng的同事Professor Phaibul NAIYANETR。种名是由“木桩\触笔\指针”和指节的组合,指其步足细长。

童哇地溪蟹Terrapotamon thungwa Promdam, Yeesin & Ng,2017[11]

长指地溪蟹Terrapotamon longitarsus Lheknim & Ng,2016

种名指代指节细长。

此前博特(1970)发表时的另外几种

Ti.simulum (Alcock,1909)移入坎氏溪蟹属*Kanpotamon Ng & Naiyanetr,1993(前面说了这个问题,有点怀疑属名真的是又来自于Krishna Kant Tiwari)*:拟译

Ti.beusekomae Bott,1970移入拉氏蟹属*Larnaudia Bott,1966*:拟译

Ti.artifrons(Bürger,1894)移入卵型溪蟹属*Ovitamon Ng & Takeda,1992*:拟译

Ti.adiatretum移入平滑溪蟹属*Teretamon Yeo & Ng,2007*:拟译

而小巧“中国溪蟹”"Chinapotamon" pusillum (Song,1984)曾经也作为内溪蟹属成员发表[9]


另外由于内溪蟹采集困难,数量稀少,市面上见到的产于越南的甚至国内的都几乎不能确定产地而无法鉴定。通常所能见到的几种全部都可能是新种。

颜色不是分种的重要依据!但是如果熟悉种类了以后再通过颜色去判断是可行的!
