Проведено ревью инкубирующих во рту видов рода Betta, обитающих в Тайланде с описанием двух новых видов из группы B. pugnax
Review of the mouthbrooding Betta (Teleostei, Osphronemidae)Abstract
The mouthbrooding species of the genus Betta from Thailand are reviewed. Six species are reported: Betta pallida, B. prima, B. pi, B. simplex and two new species of the B. pugnax species group, B. apollon sp. nov. and B. ferox sp. nov., both from peninsular Thailand. Diagnosis, description, illustrations and habitat notes are provided for all six species. Betta apollon sp. nov. is characterised by an unusually extended last branchiostegal ray and 25-26 anal fin rays. Betta ferox sp. nov. is distinguished from all other species of the B. pugnax group by the combination of the following character states: body depth at dorsal fin base 31.4-35.0% of SL, head length 30.0-33.6 % of SL, transverse bars on caudal fin, chin-bar and postorbital stripe present, 26 anal fin rays, 29-31 (mode 30) lateral scales, a lanceolate caudal fin shape and absence of a broad dark marginal band on anal fin. Statistical analyses of selected characters were calculated to test significance of differences between species and species groups.
