Unveiling Singapore's Hidden World: The Discovery of 115 New Fungus Gnat Species

In a landmark achievement for biodiversity research, scientists have documented 120 species of fungus gnats (Diptera: Mycetophilidae) in Singapore, with an astonishing 115 of them new to science. This discovery, published on December 30, 2025, in the journal Integrative Systematics: Stuttgart Contributions to Natural History, marks the first comprehensive study of these tiny, fungus-loving flies in the city-state. 58 57 Led by Professor Dalton de Souza Amorim from the University of São Paulo and hosted by Dr. Yuchen Ang, Senior Curator of Insects at the National University of Singapore's (NUS) Lee Kong Chian Natural History Museum (LKCNHM), the project highlights Singapore's role as an unexpected hotspot for insect diversity despite its urban landscape.

The research team analyzed 1,454 specimens collected over a decade starting from 2012 across 107 sites, including mangroves, swamp forests, primary rainforests, secondary forests, and even urban green spaces. This effort not only expands the known Oriental Mycetophilidae fauna by over 25% but also introduces a new genus, Integricypta, underscoring the untapped potential in 'dark taxa'—abundant yet understudied groups. 59

Understanding Fungus Gnats: Tiny Architects of Forest Ecosystems

Fungus gnats, scientifically known as Mycetophilidae, are slender flies typically measuring just a few millimeters in length. Their name derives from their close association with fungi, on which their larvae feed and develop. Adults are often seen hovering in damp, shaded forest environments, drawn to light and fungal patches. 58

Ecologically, these insects play crucial roles in nutrient cycling and decomposition. By shuttling between fungal patches, they aid in spore dispersal and influence fungal community structures, which are foundational to forest health. While some species can become pests in greenhouses by infesting potted plants, most tropical fungus gnats contribute positively to ecosystem processes. In Singapore's context, their diversity suggests a robust fungal network supporting the nation's remnant forests. 57

  • Feed on fungi, facilitating decomposition.
  • Disperse spores, maintaining fungal balance.
  • Indicator species for moist, healthy habitats.

Dr. Ang notes, “Their tight association with fungi strongly suggests they’re an important part of fungal-driven forest processes.” 58

The Science Behind the Discovery: Integrative Taxonomy in Action

The study exemplifies 'dark taxonomy' or integrative taxonomy—a hybrid approach combining DNA barcoding with morphological analysis. Specimens were first sorted using a short DNA sequence (cytochrome c oxidase subunit I, or COI barcode), grouping them into Molecular Operational Taxonomic Units (MOTUs). High match rates (95-99%) between DNA clusters and physical traits validated this method, allowing efficient handling of vast specimen numbers. 59

Malaise traps, tent-like nets that capture flying insects, were deployed at diverse sites. This 'reverse taxonomy'—starting with bulk samples rather than targeted hunts—proved ideal for dark taxa where traditional methods falter under sheer volume.

Dominant genera include Neoempheria (31 species), Epicypta (29 species), and Manota (14 species), revealing a 23:1 ratio of undescribed to described species regionally. 59

Honoring Trailblazers: Species Named After Singapore's Notable Women

In a nod to gender equity in science—where species names historically favor men—31 new species honor inductees of the Singapore Women's Hall of Fame (SWHF), an initiative celebrating pioneers in arts, sports, rights, and more. Professor Amorim stated, “We wanted to tell a bit of Singapore’s story through these names.” 57

Dr. Ang emphasized, “A modest step towards greater gender parity.” Such naming immortalizes legacies while spotlighting underrepresented figures. 58

Singapore as a Biodiversity Powerhouse Amid Urbanization

Singapore, spanning just 730 km², punches above its weight in biodiversity. Positioned in the Indo-Malayan hotspot with high endemism, it hosts thousands of insect species despite 90% urbanization. The 'City in Nature' initiative integrates green corridors, parks, and nature reserves, preserving habitats where these gnats thrive.

This discovery boosts known arthropod diversity, with implications for monitoring development impacts. Rare singletons like Aspidionia janetjesudasonae flag vulnerable microhabitats. 58

  • High endemism due to island geography.
  • Urban forests sustain surprising diversity.
  • Baseline for NParks conservation planning.

Navigating Dark Taxa: Revolutionizing Insect Taxonomy

Dark taxa like fungus gnats challenge taxonomists with overwhelming diversity. Traditional morphology is labor-intensive; DNA barcoding scales it up. This study's 85% coverage of trap samples demonstrates feasibility for tropics-wide revisions. 100

Professor Amorim calls it “front-edge” for diverse groups. Future expansions target Keroplatidae, predatory kin.

Implications for Conservation and Ecosystem Management

Mapping distributions aids habitat protection. Species tied to primary forests inform land-use decisions. As climate change stresses fungi, gnats serve as biomonitors for forest health. 57

Singapore's NParks can leverage this for the Singapore Index on Cities' Biodiversity. International collaborations via NUS exemplify higher ed's role in global science.
