• Ndong Mbong - CBL 01 / 10
• Bonepoupa - CLL 03 / 18

• CMM 8 - Collected near the Edea to Kribi road by Kämpf, Sonnenberg & Tränkner in 2000.
• C 01 / 77 - Collected by Kullmann, Misof & Sonnenberg 2001 in a small stream crossing the Edea - Kribi road near the village of Koukoué.
• C 01 / 78 - Collected by Kullmann, Misof & Sonnenberg in 2001 at Mangoule on the Douala - Edea road 1· 5 km from the exit to Yabassi. This was a swampy habitat on the left of the road behind the last houses & is reported as easy to see.
• KV 03 / 14 - Collected by Kullmann & Völker in 2003 in a small stream crossing the Mbambou - Mouanko road a few kilometres from the Oil Palm Plantation towards Mouanko.

On the road from Edea to Dizangue & Ndonga in the Koungué. Found in a small forest stream near the village Koungué Ndonga. This location fished by Kämpf, Sonnenberg & Tränkner in 2000.
This location was a small river/stream in forest approx 3 metres wide & 0·4 m deep. The bottom was sand covered by mud & leaves. Water temperature 26°C, air temperature 28°C, pH 4·9, conductivity 10µS/cm.
Sympatric species at this location - Epiplatys infrafasciatus, A.ahli, Kribia nana, young Benitochromis cf.finleyi & Barboides gracilis.

North of Kribi up to Douala, near the Wouri River. Replaced southerly by A.loennbergii & northerly by A.splendopleure.

During initial collections in the range of this species Chauche, Mallet, Poliak (1985 - CCMP 85 / 8 & 85 / 9) & also Eberl, Legros & Vlijm (1989 - C 89 / 33 & 89 / 47) reported differences with A.splendopleure which at the time were thought to be in this range.
Later, all Chromaphyosemion collected between Douala & Kribi were assigned the name sp.aff.splendopleure Dizangue.
In 2005 & 2006 J.F.Agnèse published DNA results of splendopleure. However, the results led to some confusion & Sonnenberg attempted to classify splendopleure populations on colouration. This led to the description of koungueense.
