A research team led by National Chung Hsing University Department of Entomology associate professor Lee Hou-feng (李後鋒) was the first to name an undocumented termite species found in eastern Taiwan.
The discovery represented the last piece of the puzzle of termite taxonomy, Lee said yesterday, adding that he is part of a transnational team that includes members of the department, National Taiwan University, as well as foreign academics in the Czech Republic, Belgium and China.
Part of the Stylotermitidae family, the species is an intermediate between the Kalotermitidae and Rhinotermitidae families, he said.

Once found worldwide, the Stylotermitidae can now only be found in Asia, he said, adding that scientific records on the species have been scarce since the 1980s.
The team has named it Stylotermes halumicus, Lee said, borrowing the word “halum” from the Bunun word for “pangolin.”
He said this was to thank the Bunun for their assistance in a pangolin conservation project hosted by National Pingtung University of Science and Technology.
The species was found in the trunk of a living tree in Taitung County’s Luanshan (鸞山) area, subverting the established notion that termites live in withered, dead trees or soil, he said.
Its unusual habitat might be why it was never documented in Taiwan over the past centuries, Lee said.
When the researchers collected the species in 2014, they assumed it was similar to the termites found in households, only bigger, team member and doctoral student Liang Wei-ren (梁維仁) said.
After examining its biological traits, the team learned that it is not one of the known termite species in Taiwan, he said.
Its evolution level is situated between the Kalotermitidae and Rhinotermitidae families, which vary widely in their respective habitats and impact on human life, he said.
Kalotermitidae often live in withered branches, with hundreds of termites in a colony; Rhinotermitidae live underground, with each colony housing up to 100,000 insects and can cause big economic losses if they are active in buildings, he said.
What happened between the two evolution stages is a long-term question for entomologists, to which their discovery might provide an answer and allow Taiwan to play a more important role in global termite research, he added.
The team’s findings have been published in the journals the Annals of the Entomological Society of America in 2017 and Invertebrate Systematics last year.
UPGRADE: The Kang Ding-class frigate is replacing its Chaparall missiles with Tien Chien II and Hua Yang VLS, which would provide it with long-range, 360° air defense Taiwan plans to produce 1,200 to 1,376 Hai Chien II missiles (海劍二, Sea Sword II) — also known as TC-2N — to serve as the standard air defense system of the navy’s surface combatant fleet, a source said yesterday. Last week, the Hai Chien II, the naval version of the Tien Kung II missile (天劍二, Sky Sword II), completed a live-fire test in waters off the National Chungshan Institute of Science and Technology’s Jiupeng facility (九鵬) in Pingtung County’s Manjhou Township (滿州). The MIM72 Chaparral and other dated air defense missiles that currently arm Taiwanese ships have inadequate range to combat Chinese
REASONS FOR TRAVEL: An assistant professor said that proposed amendments to penalize drivers if they used drugs overseas would not deter people from traveling People who operate a motor vehicle under the influence of marijuana would have their driver’s license revoked, even if they used the substance while overseas, the Ministry of Transportation and Communications said yesterday, citing proposed amendments to the Road Traffic Management and Penalty Act (道路交通管理處罰條例). The amendments would also authorize the government to revoke the licenses of people determined to have used Category 1 or Category 2 narcotics, even if they were not operating a vehicle while under the influence of drugs, as well as ban them from taking the license test for three years, the ministry said. People aged 18 or
Johanne Liou (劉喬安), a Taiwanese woman who shot to unwanted fame during the Sunflower movement protests in 2014, returned to Taiwan last night after being deported from the US. She is to stand trial in Taiwan for charges involving embezzlement, fraud and drug crimes. The Criminal Investigation Bureau (CIB) said it took her into custody at Taiwan Taoyuan International Airport and would first question her before transferring her to the New Taipei District Prosecutors’ Office. She was arrested upon disembarking a flight from San Francisco that landed shortly before 7pm. Liou absconded to the US in 2019 after jumping bail
Shih Hsin University President Chen Ching-he (陳清河) yesterday issued a public apology for comments made in his commencement speech last week, stating that he has asked the school to suspend his duties and halt his wages for two months as a show of contrition. At the commencement ceremony on May 30, Chen said, “If you don’t manage your time well, or your own emotions, or your health, then I am telling every one of you — put a quick end to ‘you,’ because the world has no need for ‘you.’” The comments have sparked significant controversy online, and Chen through an open
