After Otto Hofmann, an Austrian aquarist who discovered the species with Ed Pürzl.

4 cm (Radda & Pürzl 1987), 30.5mm (Holotype), 26-30mm (Paratypes).

• D = 11-12, A = 14-15, D/A = +6-7, ll = 30-32 (Radda)

Aphyosemion

hofmanni

• Aphyosemion hoffmani Wildekamp, Romand & Scheel 1986
• Aphyosemion hoffmanni Scheel 1990

• Munalzamb-Mageni
• GHP 80 / 12. Iméno Mbila
• GJS 00 / 6 - Myanga
• GJS 00 / 8 - Takamogikou

• GJS 00/6 - Myanga - A hofmanni collected together with some barbs and Clarias.
  This locality was water temperature 21°C, pH 5·3 and the conductivity 1 microsiemens.
• GJS 00/8 - Takamogikou - Collected in a stream named Boungoma. Here were found a very handsome population of A. joergenscheeli that later actually split out into two different phenotypes - a very blue and a very red one. Here were also found a very handsome and variable A.hofmanni. Unfortunately this one did not make it to Europe, only 4 females survived the trip.
  

Collection point GHP 80 / 12 on the road from Mimongo (via Mokabou) to Mbigu near Imeno Mbila, 55 km from Mimongo. du Chaillu Massif, Ngounié Province, southern Gabon.

Very small distribution area apparently restricted to the highest parts of the Massif in the Mbomi drainage. Closest neighbouring Aphyosemion is A.lamberti.

Small mountain streams at an altitude of 600 metres. Water depth was often recorded at 1 cm (shallow areas appear to be their favourite habitat). Air & water temperatures taken at 0900 was 20'C. Sympatric sp. include - Aphyosemion ocellatum, Barb sp. Clarius sp. & Ctenopoma sp.

Collecting place of A.hofmanni & A.ocellatum Du Chaillu Massif, Gabon.

Originally collected by Purzl & Hofmann in 1980 from Imeno Mbila a small mountain stream on the road between Mimongo & Mbigu 55 km from Mimongo. Males only survived the trip back to Austria.

The holotype & paratypes ( being 2 males, 7 females & 43 sub-adults are deposited in the Musee Royal de l'Afrique Centrale. Tervuren, Belgium.

Radda considered this sp. to belong to the A.elegans group from meristic & morphological data but this was not taken up in various other articles.

Only males survived the return journey to Austria.

Little has been written about this sp. but breeding may be similar to A.ocellatum.
