三色麗泉蟹定種

2024-01-16寵物

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".

這是一個非常令人興奮的訊息！最近有一種來自印度尼西亞加利曼丹（婆羅洲）的淡水螃蟹被發現，它被命名為Lepidothelpusa meneri，具有獨特的三色甲殼，與其他Lepidothelpusa屬物種有所區別。此前，這種螃蟹在業余愛好者中被引進，被稱為"Lepidothelpusa spp. "藍婆羅洲"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.

這個屬名為Lepidothelphusa的淡水螃蟹屬，最初僅在婆羅洲北部的砂拉越地區發現，已知有六個已確認的物種，分別是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.

現在，該屬首次在印度尼西亞婆羅洲地區被報道，最近從Kalimantan Barat省Sintang Regency的Gunung Kelam收集到標本。Lepidothelphusa menneri n. sp. 具有非常獨特的三色斑紋，在其同屬物種中獨一無二。它還可以透過甲殼、上唇、雄性腹部和雄性第一性孔器的特征與同屬物種輕松區分開來。
