RRI.CO.ID, Jakarta - Indonesia’s status as a global biodiversity hotspot has been further solidified following the successful identification of two new endemic moth species by the National Innovation and Research Agency (BRIN). The discovery, focusing on the genera Glyphodella and Chabulina, marks a significant milestone in entomological research, uncovering unique evolutionary traits within the nation's tropical ecosystems.

The research team, led by Hari Sutrisno and Rosichon Ubaidillah from BRIN’s Biosystematics and Evolution Research Center, conducted extensive field surveys across Papua and Sulawesi between 2002 and 2017.

Their findings, supplemented by a deep-dive analysis of specimens at the Museum Zoologicum Bogoriense (MZB) in Bogor, culminated in the naming of Glyphodella fojaensis Sutrisno & Ubaidillah, 2026 and Chabulina celebesensis Sutrisno & Ubaidillah, 2026.

According to Rosichon Ubaidillah, the two species are distinguished by highly specific morphological characters, particularly in their wing patterns and genital structures.

"Glyphodella fojaensis features distinct circular yellow spots on its forewings and a male genitalia structure that differs from its relatives. Meanwhile, Chabulina celebesensis can be recognized by its unique wing line patterns and characteristic genital shape," he explained in a statement released in Jakarta on Tuesday, March 3, 2026.

As quoted by Antara, these distinct traits served as the primary scientific basis for classifying them as new species, reflecting unique evolutionary adaptations to their respective habitats.

The habitats of these nocturnal moths are as specialized as their morphology. Glyphodella fojaensis thrives in the primary tropical forests of the Foja Mountains in Papua, while Chabulina celebesensis was discovered in the secondary tropical forests of Sulawesi.

Researchers utilized light traps for collection and employed high-precision microscopy for detailed observations. They then documented the specimens as part of the national collection at MZB.

Despite the excitement of the discovery, the research team issued a sobering reminder regarding the vulnerability of these endemic insects. Given their limited geographic range, both species are highly susceptible to environmental shifts, including deforestation and habitat degradation.

"Therefore, efforts to protect the forest ecosystems in Papua and Sulawesi are essential so that these endemic species can continue to survive," emphasized Rosichon.

The findings were recently published in the February 2026 edition of the international journal Raffles Bulletin of Zoology (Volume 74, pages 87–94). Titled "Description of two new endemic species of the closely related genera, Glyphodella and Chabulina from Indonesia," the study adds vital data to Indonesia’s insect diversity, specifically within the Crambidae moth family, and underscores the urgent need for ongoing conservation in the region's remaining wilderness. ***
