NEW DELHI. A study by scientists from three countries has reported a new genus of the Old World treefrog family Rhacophoridae — the first report of a tree frog species (Striped Bubble-nest frog) from the Andaman Islands.

The study was led by Prof S D Biju of Delhi University, and included researchers from India, Indonesia and China.

The new genus ‘Rohanixalus’ is named after Sri Lankan taxonomist Rohan Pethiyagoda.

A taxonomist is a biologist who groups organisms into categories. A plant taxonomis, for example, may study the origins and relationships between different types of roses while an insect taxonomist may focus on the relationships between different types of beetles.

The findings are published in an article titled ‘New insights on the systematics and reproductive behaviour in tree frogs of the genus Feihyla, with description of a new related genus from Asia (Anura, Rhacophoridae)’ in the current issue of Zootaxa, an international journal of animal systematics.

“Our discovery of a treefrog member from Andaman Islands is unexpected and once again highlights the importance of dedicated faunal surveys and explorations for proper documentation of biodiversity in a… country like India. This finding also uncovers an interesting new distribution pattern of treefrogs that provides evidence for faunal exchange between Andamans and the Indo-Burma region,” said Biju.

The scientists studied “external morphology of adults and tadpoles, phylogeny, calls, and breeding biology of several treefrog species widely distributed across South, Southeast, and East Asia” to confirm that it is a new genus.

Researchers said Rohanix-alus is the “20th recognised genus of the family Rhacopho-ridae and currently comprises eight out of the 422 known Old World treefrog species found in Asia and Africa”.

They are characterised by a “rather small and slender body (2-3 cm long), a pair of contrastingly coloured lateral lines on either side of the body, minute brown speckles scattered throughout the upper body, light green-coloured eggs laid in arboreal bubble-nests, and several unique behavioural traits including maternal egg attendance”.

Besides DU, the team had researchers from Zoological Survey of India – Andaman and Nicobar Regional Centre, and National Centre for Cell Science, in addition to researchers from Indonesian Institute of Sciences, Chengdu Institute of Biology (China) and Chulalongkorn University (Thailand).

Prime Minister Dr Harini Amarasuriya issuing a message on the occasion of the Hajj festival called upon all Sri Lankans to build a society valued with peace and harmony, guided by unity and solidarity beyond all differences

The Prime Minister’s message:

“On the occasion of “Eid-ul-Adha” or the Hajji Festival, celebrated with great reverence by Muslims across the world upholding the values of selflessness, unity, and compassion, I extend my felicitations to the Muslim community in Sri Lanka and around the world.

On this special Day, the festival of Hajji commemorates the boundless devotion to God and the noble spirit of generosity demonstrated by Prophet Ibrahim. This festival reflects the willingness of humanity to dedicate even its most precious possessions for the greater good of humankind and the devotion towards the God.

On this day, the most important lesson we must all understand is the value of rising above our differences and standing together in unity and solidarity. The message of Eid-ul-Adha, founded upon sharing and compassion, serves as a great example in our journey towards building a strong, peaceful, and prosperous Sri Lanka.

Therefore, setting aside narrow divisions, we must all resolve to act with respect and kindness towards one another and work together to create a society valued with peace and solidarity.

May this Hajji Festival bring happiness, peace, prosperity, and blessings to you all”.

Rajitha calls for combined lists, denounces those unwilling to join as traitors

Ranil-led group asks govt. to hold PC polls

Former Cabinet Minister Dr. Rajitha Senaratne yesterday (27) claimed that there was no consensus between the JVP and the NPP regarding the long delayed Provincial Council (PC) polls.

Dr. Senaratne said that though JVP General Secretary Tilvin Silva had declared in Jaffna, over the last weekend, that it wouldn’t be possible to conduct PC polls this year, due to financial constraints and legal impediments, the position of NPP General Secretary Dr. Nihal Abeysinghe was different.

Addressing the media at Hotel Nippon, on behalf of the People’s United Opposition grouping, operating out of Ranil Wickremesinghe’s Flower Road Office, Dr. Senaratne, who represents the UNP, claimed that the JVP/NPP was all out to postpone the long delayed PC polls. The New Democratic Front (NDF) parliamentary group, elected to the current Parliament, received the backing of Wickremesinghe.

The ex-Minister explained how the NPP, with a 159-member parliamentary group, could comfortably secure the approval of the Parliament to conduct the PC polls under Proportional Representation system.

Declaring that they would submit combined candidate lists at the PC polls, Dr. Senaratne declared that those who declined to join them would be considered traitors.

Dr. Senaratne emphasised that there was no need for alliances and their objectives could be achieved through fielding combined candidate lists.

The Illankai Thamil Arasu Kadchi (ITAK) was represented by former lawmaker and acting Secretaray General of ITAK but the Sri Lanka Podujana Peramuna (SLPP) and the main Opposition Samagi Jana Balawegaya (SJB) weren’t represented.

Convenor of the People’s United Opposition Prof. G. L Peiris, at the beginning of the briefing, explained how the people were deprived of their democratic rights by the NPP, through the postponement of PC polls.

On Tuesday (26) MPs Shanakiyan Rasamanikkam, Mano Ganesan, and Nizam Kariapper attended a joint Opposition discussion with SJB and others, organised by PAFFREL. MP Rasamanikkam has criticised the delay in holding PC elections.

The Batticaloa District MP highlighted that he had already presented a private member’s bill to facilitate the conduct of elections, under the earlier system.

Rasamanikkam said:”The four Opposition members representing the Parliamentary Select Committee affirmed their stance to hold the Provincial Council elections under the preferential voting system.

“We noted, however, that the establishment of this committee appears to be a measure to further delay the process.

“Concurrently, an Additional Solicitor General of the Attorney General’s Department presented two proposals for conducting the elections.

“One of these recommendations involves introducing minor amendments concerning women and youth representation to the private member’s motion I tabled in Parliament, which seeks to hold the Provincial Council elections under the previous system.”

Meanwhile, PAFFREL said that altogether 42 political parties and civil society organisations were involved in that discussion.

PAFFREL said that of the 42 political parties and monitoring organisations that participated in the discussion, all but one political party consented to endorse the following joint statement. And it was decided to forward the joint statement to the Parliamentary Select Committee and the government.

“We, the secretaries of political parties and representatives of the other organisations, who attended the meeting organised by PAFFREL at the Hector Kobbekaduwa Agricultural Training and Research Institute, on 26 May, 2026, agreed to the proposal adopted to hold the Provincial Council elections as per the electoral system prevailed prior to the enactment of Act No. 17 of 2017, pending the final outcome of the Parliamentary Select Committee. We also agreed to ensure 25% representation of women and youth on a voluntary basis.”
