Juergen Schmidt, noted author and researcher on wild bettas and other tropicals reported on a species of Betta macrophthalma from the blackwater swamps of Pekan Nanas northwest of Singapore. This species was first identified by Regan (1910) and placed the species in the Pugnax group. Years later Allan and Barbara Brown re-discovered the species and placed the species in the B. waseri group based upon the distinct throat color patterns, the large adult size and plain body coloration.
Further recent examination by Schmidt noted a resemblance to the B. hipposideros species but differed from the species in several aspects but principally in having an omega (Ω) pattern on the throat. This southern Malaysian population has now been described as a new species within the Waseri Complex – B. omega.
Luis — I have searched for a photo unsuccessfully for some time now. I have asked for a copy of the paper by Schmidt, which includes photos and hopefully will have it shortly. We will create a species page on our page and post the photos there.
