Nothobranchius Milvertzi
📖 Overview
The accompanying fauna of the ephemeral pools consisted of non-annual species, such as Barbus haasianus, Lacustricola moeruensis, Protopterus sp. and Pseudocrenilabrus cf. philander . The type locality was a large ephemeral pool formed in a river bed, as a standing fragment of the seasonal river, about 50 m long and 10 m wide, and about 2 m deep at its deepest point; the edge of the habitat was heavily overgrown by grass and the aquatic vegetation consisted of Nymphea species; the water was brown and slightly turbid, whereas at shallower parts the bottom of the pool was visible . Eggs slightly oval, measuring 1.27-1.36 mm on average, with short filaments on chorion .
🔬 Taxonomy
🐟 Physical Description
Dorsal spines (total): 0; Dorsal soft rays (total): 15 - 17; Anal spines: 0; Anal soft rays: 15 - 18. Diagnosis: Nothobranchius milvertzi belongs to the Nothobranchius taeniopygus species-group, presenting the diagnostic characters of this complex of caudal and anal fin with broad light submarginal band and dark distal margin in males . Nothobranchius milvertzi is distinguished from all other species of this complex, with the exception of N. malaissei and N. hassoni, by having an anal fin with orange submarginal band and a dark red-brown distal margin . It is distinguished from these two last mentioned species by having a red caudal fin with narrow orange semicircular submarginal band and wide dark red-brown distal margin . Furthermore, the species presents within the species-group the unique morphometric characters of head length 28.5-31.5% of standard length, interorbital width 39-46% of head length, and snout length 18-20% of head length . : short and / or deep.
