Nothobranchiidae (African rivulines)
Etymology: Nothobranchius: Greek, nothos = false + Greek, brangchia = gill (Ref. 45335); seegersi: The species is named in dedication to its first collector, the enthusiastic aquarist and ichthyologist Lothar Seegers, Germany (Ref. 87047).
Eponymy: Dr Lothar Seegers (1947–2018) was a German biologist and enthusiastic aquarist. [...] (Ref. 128868), visit book page.

背面の脊椎 (合計) : 0; 背鰭 (合計) : 16 - 17; 肛門の骨: 0; 臀鰭: 17 - 18; 脊つい: 31 - 32. Diagnosis: Males of Nothobranchius seegersi share with the other members of the Nothobranchius neumanni species group a combination of colouration characters, which distinguish them from all other species of the genus: caudal fin red or partially red; pectoral fin hyaline; anal fin yellow with red stripes, proximal portion light bluish grey (Ref. 87047). It is distinguihed from N. neumanni by bright light blue scales, vs. pale bluish grey; an irregular pattern formed by red scale margins on lateral body and head vs. uniform; and a single, blue male colour morph, vs. two colour morphs, blue and red; both male and female of N. seegersi have a relatively higher predorsal length compared to N. neumanni, 60.3-68.8 vs. 54.8-61.0% of standard length in males, 68.0-68.4 vs. 57.1-64.6% of standard length in females (Ref. 87047). Based on osteological characters, Nothobranchius seegersi differs from N. neumanni by having a conspicuously longer lateral process of the post-temporal, and by having short antero-dorsal process of the urohyal (Ref. 87047).
Body shape (shape guide): fusiform / normal.
This species is found in seasonal pools; the type locality was at the time of collection a small and very shallow pond, about 3x5 m wide and 0.25 m deep, without aquatic vegetation, in the open woodland; the water was brown and very turbid (Ref. 87047).
