🌍🐾 世界の動物・昆虫ニュース — 2026.08.24 新種 2件 ＋ 新知見 3件 ＝ 計5件 🔬 新種発見 ― 2選 1. 「チョウの模様」を背負う毒蛇 ― チベット秘境メドクから新種のピットバイパー 爬虫類（クサリヘビ科） 中国・チベット 2026年 ※イメージ：同属種 Ovophis monticola（マウンテン・ピットバイパー）| 新種はより短くずんぐりした体形で、背に黒いチョウ形の斑紋を持つ 東ヒマラヤの生物多様性の宝庫、中国チベット自治区メドク県の調査で、マムシの仲間の新種 Ovophis medogensis（英名：Medog Pitviper）が記載された。褐色の背に並ぶ19〜20個の黒い「チョウ形」の斑紋と、眼の後ろに走る橙色の縞が特徴。形態とミトコンドリアDNAの両方が独立した系統であることを支持した。近縁種との遺伝距離は5.5〜13.5%。発見はこの地域の爬虫類の多様性がまだ底知れないことを物語る。Asian Herpetological Research誌に掲載。 🔗 2. アフリカ最後の「生物多様性の空白地帯」で新種ラッシュ ― アンゴラの高原から約70の未知種 昆虫・クモほか アンゴラ 2026年 ※イメージ：ゴライアスオオツノハナムグリ Goliathus goliatus | 調査では「手のひらサイズ」の果実食甲虫も見つかった アンゴラ南東部の未踏査地リシマ高原で行われた調査「Cassai Life Atlas」が、トンボ8新種、バッタ類3新種、ガ・チョウ類約60新種という驚きの成果を報告した。手のひら大の果実食甲虫や、蛍光ブルーの模様をもつ小さなクモ、テントウムシに擬態するクモまで。栄養の乏しい土地ゆえ個体数は少ないが、特殊化した種の多様性は予想をはるかに超えていた。ここは数千km下流の生態系と人々を潤す大河の水源地でもあり、調査結果は流域全体の保全の基礎資料となる。 🔗 🧠 既知種の新たな発見・知見 ― 3選 3. 温暖化はモルフォチョウの「青い輝き」を奪う ― 蛹が浴びた熱で虹色が鈍る 気候変動・発生

A new green pitviper species discovered in Sichuan, China, was confirmed through genetic analysis and named after the philosopher Laozi. A newly identified pitviper with bright grass-green scales and amber-colored eyes has been discovered in the misty mountains of western Sichuan, China. Researchers from the Chengdu Institute of Biology and the Giant Panda National Park uncovered the species while surveying the biodiversity-rich West China Rain Zone. What had long been considered a common snake turned out to be an undocumented species. The team named it Trimeresurus lii, also known as the Huaxi Green Pitviper, in recognition of the region’s cultural heritage and the national park where it was found. “The specific name lii honors Li Er, the ancient Chinese philosopher better known as Laozi,” said the research team, led by Bo Cai. “His teachings emphasize the harmonious coexistence between humans and nature, a principle that perfectly aligns with the conservation mission of the Giant Panda National Park where this species was discovered.” Genetic Analysis Reveals a Distinct Species The Huaxi Green Pitviper is the 58th known species in the Trimeresurus genus and only the second member of its particular subgenus identified in Sichuan Province. For many years, these snakes were...
