三色丽泉蟹定种

2024-01-16宠物

A while since we've posted a "Crustaceans in the News" story - so glad to find this absolutely stunning new species of freshwater crab from Kalimantan (Borneo), Indonesia has just been described - 𝐿𝑒𝑝𝑖𝑑𝑜𝑡ℎ𝑒𝑙𝑝ℎ𝑢𝑠𝑎 𝑚𝑒𝑛𝑛𝑒𝑟𝑖. With a unique tri-coloured carapace, setting it apart from the other 𝐿𝑒𝑝𝑖𝑑𝑜𝑡ℎ𝑒𝑙𝑝ℎ𝑢𝑠𝑎 𝑠𝑝𝑝. Previously imported into the hobby as 𝐿𝑒𝑝𝑖𝑑𝑜𝑡ℎ𝑒𝑙𝑝ℎ𝑢𝑠𝑎 𝑠𝑝. "Blue Borneo" or "Tricolour".

这是一个非常令人兴奋的消息！最近有一种来自印度尼西亚加里曼丹（婆罗洲）的淡水螃蟹被发现，它被命名为Lepidothelpusa meneri，具有独特的三色甲壳，与其他Lepidothelpusa属物种有所区别。此前，这种螃蟹在业余爱好者中被引进，被称为"Lepidothelpusa spp. "蓝婆罗洲"或"三色"。

The gecarcinucid freshwater crab genus, 𝐿𝑒𝑝𝑖𝑑𝑜𝑡ℎ𝑒𝑙𝑝ℎ𝑢𝑠𝑎 Colosi, 1920, is known only from Sarawak in northern Borneo, with six recognised species i.e. 𝐿𝑒𝑝𝑖𝑑𝑜𝑡ℎ𝑒𝑙𝑝ℎ𝑢𝑠𝑎 𝑐𝑜𝑔𝑛𝑒𝑡𝑡𝑖𝑖 (Nobili, 1903); 𝐿. 𝑓𝑙𝑎𝑣𝑜𝑐ℎ𝑒𝑙𝑎 Grinang & Ng, 2015; 𝐿. 𝑙𝑖𝑚𝑎𝑢 Grinang & Ng, 2015; 𝐿. 𝑙𝑜𝑖 Grinang & Ng, 2015; 𝐿. 𝑝𝑎𝑑𝑎𝑤𝑎𝑛 Grinang & Ng, 2015; and L. sangon Grinang & Ng, 2015.

这个属名为Lepidothelphusa的淡水螃蟹属，最初仅在婆罗洲北部的砂拉越地区发现，已知有六个已确认的物种，分别是Lepidothelphusa cognettii (Nobili, 1903)、L. flavochela Grinang & Ng, 2015、L. limau Grinang & Ng, 2015、L. loi Grinang & Ng, 2015、L. padawan Grinang & Ng, 2015以及L. sangon Grinang & Ng, 2015。

The genus is now reported from Indonesian Borneo for the first time, from specimens recently collected from Gunung Kelam in Sintang Regency, Kalimantan Barat Province. 𝐿𝑒𝑝𝑖𝑑𝑜𝑡ℎ𝑒𝑙𝑝ℎ𝑢𝑠𝑎 𝑚𝑒𝑛𝑛𝑒𝑟𝑖 n. sp. has a very distinctive tri-coloured pattern in life, unique among congeners. It can also easily be separated from congeners by carapace, epistome, male pleonal and male first gonopod characters.

现在，该属首次在印度尼西亚婆罗洲地区被报道，最近从Kalimantan Barat省Sintang Regency的Gunung Kelam收集到标本。Lepidothelphusa menneri n. sp. 具有非常独特的三色斑纹，在其同属物种中独一无二。它还可以通过甲壳、上唇、雄性腹部和雄性第一性孔器的特征与同属物种轻松区分开来。
