Classification / Names Common names | Synonyms | Catalog of Fishes (gen., sp.) | ITIS | CoL | WoRMS | Cloffa

Actinopterygii (ray-finned fishes) > Cyprinodontiformes (Rivulines, killifishes and live bearers) > 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).

Environment / Climate / Range Ecology

Freshwater; benthopelagic.   Tropical

Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 16-17; Anal spines: 0; Anal soft rays: 17 - 18; Vertebrae: 31 - 32. Diagnosis: Males of this species 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 color 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, this species 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).

Biology     Glossary (e.g. epibenthic)

This species is found in seasonal pools, the type locality being at the time of collection a small and very shallow pond, without aquatic vegetation, in the open woodland; the water was brown and very turbid (Ref. 87047).
