Researchers from Kerala and Tamil Nadu person discovered 2 caller taxon of highly uncommon ant flies from India—one from a disturbed municipality wood successful Delhi and different from the Western Ghats successful Tamil Nadu— highlighting the value of conserving some municipality greenish spaces and biodiversity hotspots.
The recently discovered species, Metadon ghorpadei and Metadon reemeri, beryllium to the sub household Microdontinae (Syrphidae). These flies are known for their unsocial relation with ants, arsenic their larvae unrecorded wrong ant nest and provender connected ant brood, a specialised behaviour called myrmecophily that makes them exceptionally uncommon and hard to detect. Until now, lone six taxon of the genus Metadon person been reported from India.

The taxon were discovered by by H. Sankararaman, Assistant Professor, School of Agricultural Sciences, Amrita Vishwa Vidyapeetam, Coimbatore, and S.S. Anooj, Assistant Professor astatine the College of Agriculture, Vellayani, nether Kerala Agricultural University. The findings based connected elaborate morphological studies and DNA investigation were published successful the planetary diary Zootaxa.
According to Mr. Anooj, some morphological characteristics and DNA investigation were utilized to found the novelty of the 2 species. The survey besides reviewed the Indian fauna of the genus Metadon and redescribed six antecedently known species.
He said Metadon ghorpadei was discovered successful the bluish ridge wood of Delhi, a disturbed municipality wood spot surrounded by roads, postulation and dense residential areas.
The bluish ridge is portion of the Delhi ridge, an hold of the past Aravalli elevation scope and constitutes lone astir 1 per cent of its archetypal grade owed to fragmentation and quality pressure.
Mr. Anooj said the taxon was recovered successful a spot of moderately dense vegetation wrong the different thorny scrub forest, underscoring the hidden faunal worth of municipality forests. The researchers pass that conservation efforts successful Indian cities mostly absorption connected greenish screen alternatively than situation circumstantial biodiversity, putting specified uncommon taxon astatine risk.
The 2nd species, Metadon reemeri, was discovered successful the Siruvani hills of Western Ghats successful Tamil Nadu. The Western Ghats, a globally recognised biodiversity hotspot with precocious endemism, are mostly protected, yet lesser known insect groups similar Microdontinae stay poorly studied, Mr. Anooj said..
He said members of Microdontinae are seldom encountered due to the fact that big flies seldom sojourn flowers and thin to stay adjacent to ant nest.
Globally, galore Microdontinae taxon are considered uncommon oregon threatened owed to their specialised situation requirements and patchy distribution. Of the 454 taxon reported worldwide, lone 27 are known from the Indian subcontinent.
The researchers accent the request for targeted survey, elaborate mapping of Microdontinae situation and stricter regularisation of quality activities successful delicate areas. Controlling invasive works taxon and restoring indigenous vegetation are besides recommended to enactment situation recovery.
The researchers telephone for extended surveys crossed different Indian regions, including the Vindhya range, Deccan Plateau and bluish plains, on the with molecular phylogenetic studies to amended recognize taxon divergence and endemism.
