A new kind offungusparasite, named *Pleurocordyceps cornusynnemata*, was recently identified by researchers in the jungles of Borneo, Malaysia. With a peculiar shape that resembles a horn, this surprising creature feeds on “zombie fungi”, which are known to infect and control ants, causing them to behave strangely and eventually die.
The unprecedented finding was documented on June 2 by a team of scientists from Universiti Malaysia Sabah (UMS) and published in the renowned scientific journal Phytotaxa. Associate Professor Jaya Seelan led the research that located the parasite in a lifeless ant in the Danum Valley Conservation Area, located in Lahad Datu.
The mechanism of action of the new hyperparasite
Professor Seelan explained to Agence France-Presse (AFP) that the newly discovered fungus was classified as a “hyperparasite” due to its remarkable ability to parasitize other creatures. Its target is the “zombie fungi” of the *Ophiocordyceps* species, famous for altering the nervous systems of ants, causing them to exhibit bizarre behaviors before dying, and then emerging from their bodies.
Instead of directly manipulating the host insect’s nervous system, *Pleurocordyceps* acts differently. It infiltrates and consumes the *Ophiocordyceps* tissue that is developing inside the ant, Seelan detailed.
The expert highlighted that, although this is not the first known “hyperparasite”, it stands out as the first member of its genus to present a distinct horn-shaped physical structure.
The importance of the discovery for biodiversity
This discovery reinforces Malaysia’s position as a global biodiversity hub, home to numerous species that still await scientific documentation. The unique horn-shaped morphology of the new fungus distinguishes it from the other 26 species of *Pleurocordyceps* already cataloged in China, Thailand and Japan.
Researcher Seelan pointed out that the newly identified fungi offer vast potential for advancing science. They can be studied both for the development of a new generation of antimicrobial medicines, combating resistant infections, and for the creation of highly effective biocontrol agents to combat agricultural pests, offering a more sustainable alternative.
In an official statement, UMS vice-chancellor Datuk Dr Kasim Mansor emphasized that this achievement reflects the university’s vision to position itself as the “brain of Borneo”. He also highlighted the ability of local scientists to conduct high-impact research that captures the attention of the international scientific community.
In addition to the new globally recognized species, the research team also made the first record in Malaysia of two other fungi: *Pleurocordyceps aurantiaca* and *Pleurocordyceps nipponica*.
