Taxonomists discover new ‘true frog’ genus from South-east Asia
by Ifham Nizam
Discovering new species is fundamental for the expansion of knowledge of the endangered biodiversity of the planet, a large part of which still remains unknown to science.
It is rare to discover a completely new genus or higher taxon. Most new species discovered nowadays are part of well-known genus.
A group of taxonomists discovered a new genus of ‘true frogs’ and ‘ranid frogs’, which scientifically belong to Family Ranidae, according to a research article in the latest edition of the Journal of Asian Biodiversity, ‘Taprobanica’.
The new genus is named as “Bijurana” in honour of Prof. Sathyabhama Das Biju of the University of Delhi, India, for his enormous contribution towards amphibian research and conservation in the Indian subcontinent.
Prof. Biju is renowned as “the frogman of India” for bringing fresh fascination for Indian amphibians. He has discovered hundreds of new species new genera as well as new families. This world renowned taxonomist has been working very closely with many Sri Lankan amphibian taxonomists for decades.
The research of discovering new genus was conducted by three expert herpetologists and taxonomists in the Asian region, S. R. Chandramouli, an Indian researcher at Pondicherry University, Amir Hamidy, an Indonesian researcher at Indonesian Institute of Sciences and Thasun Amarasinghe, a Sri Lankan researcher at University of Indonesia.
The frog family Ranidae comprised 26 genera in the world. Among these, 15 genera, namely Abavorana, Amolops, Chalcorana, Clinotarsus, Huia, Humerana, Hydrophylax, Hylarana, Indosylvirana, Merystogenis, Nidirana, Odorrana, Papurana, Pseudorana and Pterorana are in the Oriental Region.
The first systematic classification of true frogs of the genus rana was carried out by world- renowned, most senior amphibian expert in the world, Alain Dubois in 1992. Prof. Dubois placed the sub-Saharan African Ranid frogs into the genus Amnirana and placed the unique species, Hylorana nicobariensis found in Nicobar Islands in South and Southeast Asian genus, Sylvirana, considered the most appropriate placement for the species at the time.
However, subsequent researchers from different parts of the world reallocated the species into different genera during the past two decades from Sylvirana to Hylarana, Hylarana to Amnirana and thereafter from Amnirana to Indoylvirana.
Actually since the discovery of Hylorana nicobariensis in 1870, the taxonomists were unable to find the correct generic position of this species. Therefore, its generic position has changed more than 10 times during last 150 years.
The tree experts reassessed the systematic position of Nicobarese species based on an integrative approach of both phylogenetic and morphological affinities and described a new genus to solve the long disputed taxonomic issue of true frogs.
The team observed these animals during last decade in Nicobar and Indonesian Islands with the support of their respective institutes and governments. They also recorded calls of Nicobarese frogs and analyzed the sounds. The description of the new genus will shed new light on the conservation of the species, as the new genus is now endemic to Southeast Asia, which earlier considered distributed up to sub-Saharan Africa.

Action suggested for the Land area:
• Coastal hutment dwellers are advised to move to safer places. Other people in the affected areas to remain indoors.
• People living in hilly areas (particularly landslide prone areas) and low lying areas in river basins are requested to be vigilant.
• Drivers and people using roads in the hilly areas are requested to be vigilant.
• Beware of fallen trees and power lines.
• Avoid using wired telephones and connected electric appliances during thunderstorms.
• General public is requested to be vigilant regarding impending extreme weather situation.

Easter Sunday attacks: Govt. says wife of Katuwapitiya Church bomber alive
Minister of Public Security Ananda Wijepala told Parliament yesterday that information uncovered during ongoing investigations indicated that Pulasthini Mahendran, also known as Sara Jasmine, linked to the 2019 Easter Sunday terror attacks, was not dead.
Responding to a question raised by Opposition MP Mujibur Rahuman, the Minister said there was no confirmation that Sara Jasmine was currently in India, despite speculation to that effect. He added that investigators suspected she may have fled the country and stressed that further inquiries were underway to establish her whereabouts.
“If necessary, the government will take steps to obtain a warrant,” Wijepala said, noting that legal action related to the Easter attacks had already been initiated, based on available evidence.
Minister Wijepala said the new government had launched an thorough probe to determine whether a political or other conspiracy had been behind the attacks that killed more than 270 people in 2019. However, he declined to disclose certain details in Parliament, citing the risk of hampering investigations.
Sara Jasmine, Mohammed Hashtun, who bombed St. Sebastian’s Church, in Katuwapitiya, in 2019, was long presumed to have died in a suicide blast in Sainthamaruthu, days after the attacks. Wijepala said attempts by previous administrations to establish her death had failed, with recent reports indicating that DNA tests conducted at the time were inconclusive.
During the debate, MP Rahuman recalled that senior figures, including then-Opposition MP Nalinda Jayatissa, had previously claimed Sara Jasmine was in India. He questioned why authorities had not sought an open warrant for her arrest whether the issue had been raised in talks with Indian officials.
Wijepala, responding on behalf of Deputy Minister of Defence Arun Jayasekara, said the government would not hesitate to pursue legal action, including warrants, if necessary.
