A new genus of the old world tree frog family discovered in Andaman Islands was named after Sri Lanka’s taxonomist Dr. Rohan Pethiyagoda, on Thursday.

A team led by Delhi University Professor S. D. Biju along with a group of researchers from India, China, Indonesia and Thailand, said it was the first time a tree frog species, Rohanixalus vittatus (Striped Bubble-nest frog), had been reported from the Andaman Islands of India.

‘Even though the amphibian fauna of Andamans has been frequently surveyed in recent years, family Rhacophoridae had not been reported from these islands.

Dr. Pethiyagoda told The Island: “Rohanixalus is a genus distributed from Northeast India to Southeast Asia, and I feel honoured that they chose to associate the name of this new genus to me.”

He added that only future research will show how the newly discovered species had got there. As you know, there are three genera of rhacophorid frogs in Sri Lanka too––Taruga, Polypedates and Pseudophilautus.

Frogs of the new genus have a unique nesting behaviour and are reported to display territorial behaviour and frequent male-male combats involving pushing, kicking, and dislodging, in order to successfully mate with a female.

Sagarika derailment disrupts coastal rail line; services to resume in two days

Published

on

Railway General Manager Ravindra Pathmapriya said on Friday that re-railing operations of the derailed ‘Sagarika’ train have already commenced and that services on the Coastal Line are expected to be restored within two days.

Addressing the media, he said the Minister had instructed officials to take all necessary measures to minimise inconvenience to passengers.

Commenting on the incident, he said: “The damaged train is a significant loss for us, especially as our fleet is already limited. We have incurred this loss and hope to rectify the situation promptly. However, we will need to deploy an alternative train in its place, and discussions are currently underway.”

The ‘Sagarika’ train, operating from Beliatta to Maradana, derailed near the Wadduwa Railway Station on Friday morning (24), causing severe damage to one track of the dual-line section.

The Railway Department has since restricted services on the affected Coastal Line up to Panadura Railway Station.

Arrangements have been made to transport passengers from Panadura to South Kalutara by Sri Lanka Transport Board (SLTB) buses, from where train services will resume towards Matara and Beliatta.

Meanwhile, the Department said efforts are underway to clear the obstruction and restore at least one track by the end of the day.
