Duri punggung (Keseluruhan (total)) : 0; duri punggung lunak (Keseluruhan (total)) : 9 - 12; Duri dubur: 0; Sirip dubur lunak: 11 - 14. Diagnosis: This species is distinguished from all other species in the Aphyosemion alpha group by two delimited orange zones on body: orange portion on opercle and orange portion above pelvic fins vs. no orange portion, with beige ventral portion vs. yellow-orange, white bluish or orange, anal fin orange, blue near basal portion and near submarginal red band, no punctuation vs. never a similar colour pattern (Ref. 119374). It is distinguished from all other species of the subgenus Chromaphyosemion by alpha-shaped mark on pre- and postopercular region, especially visible on preserved specimens, vs. no alpha-shaped mark, only some red macules (Ref. 119374).

Found in the main course of small rivers, muddy streams less than 1 m wide, hidden among dead leaves and water plants, in quiet places (Ref. 119374).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = No PD50 data [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.1 ±0.4 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
