Taxonomists discover new ‘true frog’ genus from South-east Asia

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.

CEB seeking tariff hike while making huge profits, says opposition trade union leader

Published

on

Ananda Palitha

Convenor of the Samagi Joint Trade Union Alliance affiliated with the Samagi Jana Balawegaya, Ananda Palitha, yesterday (16) said that the Ceylon Electricity Board was seeking to raise electricity tariffs by 13.56% percent although it had earned a profit of more than Rs 22,000 mn.

The CEB recently submitted its proposal to the Public Utilities Commission of Sri Lanka (PUCSL) for an electricity tariff revision for the second quarter of this year – the period effective from April 1 to June 30.

Palitha alleged that the PUCSL, in spite of knowing the massive profit earned by the CEB, at the expense of the hapless public, had chosen to allow the state enterprise to propose an additional burden.

The economic, technical and safety regulator of the electricity industry, and the designated regulator for petroleum and water services industries, should exercise its powers in terms of the PUCSL Act No. 35 of 2002 and the Sri Lanka Electricity Act No. 20 of 2009 to provide relief, the veteran trade unionist said.

Palitha emphasised that the PUCSL had the right to intervene on behalf of electricity consumers but, unfortunately, chose to facilitate the CEB’s despicable strategy. “The proposal to increase tariffs by 13.56% was meant to divert attention. The real issue at hand is the percentage of electricity tariff reduction,” Palitha said. The former UNPer found fault with the Opposition for failing to expose the CEB.

Taking into consideration the Rs 22,000 millionplus profit, the PUCSL could order the CEB to grant relief to consumers, Palitha said, adding that the CEB and PUCSL, together, deprived electricity consumers tariff reduction in the first quarter of this year, too.

In January this year, the CEB asked for a 11.59% tariff increase though it was enjoying Rs 22,000 mn profit at that time, the trade unionist said.

Palitha said that as the PUCSL received all data available to the CEB it was fully aware of the finances of the state enterprise.

In January, 2025, regardless of the NPP government floating the idea regarding as much as a 37% tariff increase, the PUCSL granted a 20% tariff reduction (25% of Rs 22,000 mn profit), Palitha said.

According to him, as a result of relief granted to the consumers, the profits had been reduced to Rs 16,000 mn but by June 2025 profits had increased to Rs 18,000 mn and there was a need to grant tariff reduction. But, the NPP, having always lashed out at the International Monetary Fund (IMF) in the run up to the presidential election, held in September 2024, started playing a different tune.

Responding to The Island queries, Palitha said that contrary to claims that the CEB proposed a 13.56% tariff increase to cover up losses caused by the importation of low-quality coal for the Norochcholai Lakvijaya coal-fired power plant, the current strategy seemed to have been adopted at the behest of the IMF.

Instead of granting tariff reduction for the third quarter in 2025, the PUCSL ordered an 18% increase, Palitha said. The trade unionist claimed that the Finance Ministry, at the behest of the IMF, directed both the CEB and the PUCSL to increase electricity tariffs by 20% in violation of the relevant Acts, he said.

Then in Oct, 2025, the CEB proposed a 6.8 % tariff increase at a time its profits were around Rs 22,000 mn. The CEB and PUCSL staged a drama over that proposal and finally, on the false pretext of the CEB’s failure to furnish its proposal on time, the revision was dropped, Palitha said. The SJB activist pointed out that the Opposition failed to highlight that consumers had been deprived of downward revision in spite of massive profits earned by the Board. “In fact, when Energy Minister Kumara Jayakody met trade unions, he very clearly declared that they were considering electricity power reduction, perhaps by 10%, 12% or 15%. But in the end nothing happened.”

Now the same drama is being enacted by the government, the CEB and the PUCSL, Palitha said.
