Abstract

Hemibates koningsi, new species, is described from southern Lake Tanganyika (Republic of Zambia) as the second species of Hemibates Regan, 1920. Males of the new species are easily distinguished from H. stenosoma (Boulenger, 1901) based on their adult color pattern, i.e. black vertical bars on the anterior flanks part and posterior horizontal bands on a silvery-whitish body coloration vs. an anterior flank color pattern of black blotches of variable number, size and shape and posterior horizontal bands. Males and females of the new species are further distinguished by their longer lower pharyngeal jaw (37.6–38.2% HL vs. 27.8–32.5% HL) with a characteristically curved keel, which is straight or only slightly curved towards the tips in H. stenosoma. The new species has on average fewer gill rakers on the first gill arch than its only congener (33–37 vs 35–43).

The moment Rich Bireley saw Konings famous image of this species during a talk nearly 20 years ago, he immediately recognized it as a new species of Hemibates. A few years later on, when I saw it in his 2nd edition Tanganyikan cichlids book, it was clear that it was a new Hemibates species, even though Konings could not see it. Funny how it was named after the very person who doubted its validity for so many years.
