Newly Found Flasher Wrasse
Fig.1 Paracheilinius Rennyae

A new species of Flasher Wrasse has been found in East Nusa Tenggara (southwestern Flores island) in the Lesser Sunda chain Island, Indonesia by scientists from Conservation International and The Indonesian Biodiversity Research Center.
Described with very unique and distinct outline to its profile. It has striking orange colours and rounded fins. Looking not unlike the smooth edge Paracheilinius Octotaenia from the red sea, Paracheilinus Rennyae is an endemic species found only in the coral reefs of Southwestern Flores and Komodo National Park.

The fish (locally known as ikan karang), was named Paracheilinus Rennyae in the latest Aqua, International Journal of Ichtyology, in recognition after Indonesian ichtylogist Renny Kurnia Hadiaty from Indonesia Institutes of Sciences (LIPI) found it. The new species of flasher wrasse from Southern Indonesia is distinguished from a complete lack of fin or filaments extensions. However, the color pattern and genetic indicates Paracheilinius Rennyae is most closely related to Paracheilinius Angulatus from The Philipines and Northern Borneo.

Flasher wrasse are favourite among the divers and underwater photographer due to their electric pattern and colour which only displayed during their ritual mating that normally occur an hour before sun down. At that time, the normally brownish-coloured male rise up in the water column and erecting their fins with short burst swimming to encourage the females to spawn.

Mark Erdmann vice president, marine, Asia Pacific from Conservation International to the Indonesia Marine Program, said around 2.400 species of flasher wrassse had been found in Indonesia with more than 1.700 of them in Papua and 1.300 in East Nusa Tenggara.
