Two types of spiders found in southern Taiwan’s Hengchun Peninsula have been identified as new species after years of analysis and cross-checking, the Taiwan Biodiversity Research Institute said on Thursday.
The new species are Idioctis parilarilao, also known as the parilarilao trapdoor spider, and Hogna arborea, or the Taiwanese tree-dwelling wolf spider, the institute said in a statement.
The discoveries came after years of effort by a research team consisting of personnel from the institute, National Taiwan Normal University, National Chung Hsing University and international experts, the institute said.

It did not specify when the spiders were first found, but said it took years of collecting specimens, reviewing published studies and DNA time series analyses, and comparing foreign samples to confirm the Parilarilao trapdoor spiders as a new species.
Ultimately, researchers determined that parilarilao trapdoor spiders belong to the family Barychelidae, and that Taiwan is the northernmost habitat of spiders in this family.
Parilarilao trapdoor spiders build nests with trap doors and live in intertidal zones, meaning they are underwater at high tide but exposed during low tide, the institute said.
Their nests are closed by watertight trap doors to ensure that there is enough air and their homes are not flooded or washed away at high tide, and the spiders slightly open the trap doors at low tide and attack prey that go past their nests.
The new species was named after the indigenous name for the area, with parilarilao meaning “living at the end of Taiwan” in the Paiwan language, the institute said.
The other species, Hogna arborea, was determined to belong to the family Lycosidae, and according to the institute, wolf spiders in this family often dwell in grasslands, farmland or meadows.
Researchers found wolf spiders living in treeholes in recent years in several areas of eastern and southern Taiwan, including Hengchun in the south and Yilan and Hualien counties in the east, and that these spiders were later confirmed to be a new species, the institute said.
The new species was named Hogna arborea, with hogna meaning “wolf spider” and arborea meaning “living on trees,” the institute said.
According to the institute, Taiwanese tree-dwelling wolf spiders have a body size of more than 2cm and are considered large compared with most Taiwanese wolf spiders.
Taiwan has more than 20 wolf spider species, the institute said.
A decision to describe a Chinese Ministry of Foreign Affairs statement on Singapore’s Taiwan policy as “erroneous” was made because the city-state has its own “one China policy” and has not followed Beijing’s “one China principle,” Deputy Minister of Foreign Affairs Tien Chung-kwang (田中光) said yesterday. It has been a longstanding practice for the People’s Republic of China (PRC) to speak on other countries’ behalf concerning Taiwan, Tien said. The latest example was a statement issued by the PRC after a meeting between Singaporean Prime Minister Lawrence Wong (黃循財) and Chinese President Xi Jinping (習近平) on the sidelines of the APEC summit
Taiwan’s passport ranked 34th in the world, with access to 141 visa-free destinations, according to the latest update to the Henley Passport Index released today. The index put together by Henley & Partners ranks 199 passports globally based on the number of destinations holders can access without a visa out of 227, and is updated monthly. The 141 visa-free destinations for Taiwanese passport holders are a slight decrease from last year, when holders had access to 145 destinations. Botswana and Columbia are among the countries that have recently ended visa-free status for Taiwanese after “bowing to pressure from the Chinese government,” the Ministry
HEALTHCARE: Following a 2022 Constitutional Court ruling, Taiwanese traveling overseas for six months would no longer be able to suspend their insurance Measures allowing people to suspend National Health Insurance (NHI) services if they plan to leave the country for six months would be abolished starting Dec. 23, NHIA Director-General Shih Chung-liang (石崇良) said yesterday. The decision followed the Constitutional Court’s ruling in 2022 that the regulation was unconstitutional and that it would invalidate the regulation automatically unless the NHIA amended it to conform with the Constitution. The agency would amend the regulations to remove the articles and sections that allow the suspension of NHI services, and also introduce provisional clauses for those who suspended their NHI services before Dec. 23, Shih said.

They would be incorporated in a first joint operation plan to be formulated in December, Kyodo reported late on Sunday, citing sources familiar with Japan-US relations. A US Marine Corps regiment that possesses High Mobility Artillery Rocket Systems — a light multiple rocket launcher — would be deployed along the Nansei Island chain stretching from Kyushu to Yonaguni near Taiwan, Kyodo said.
