This species has a somewhat confusing taxonomic history and it remains unclear whether it is conspecific with S. izecksohni (Da Cruz, 1983) or not.

The latter is considered to represent a synonym of S. myersi by Costa (2007), but the majority of authors do not follow the conclusions of that study (see below) and continue to view both as valid.

Known only from a relatively small area near the villages of Takwai I and II, Atebong Wire and Edjuingan in wester Cameroon, with records existing from the Bagwor and Mack river systems both of which are tributaries within the upper Cross River basin, western Cameroon.

Type locality is ‘West Cameroon, 5°34’N, 9°50’E’.

Aplocheilus spp. are surface-dwelling predators preying on both aquatic and terrestrial invertebrates.

In the aquarium they will learn to accept dried foods in most cases but should also be offered regular meals of small live or frozen fare such as Artemia, Daphnia, chironomid larvae (bloodworm), etc.

This species is euryhaline and mostly inhabits lowland, often coastal, habitats containing still or slow-moving brackish or freshwater.

It displays a preference for habitats with surface vegetation or overhanging cover and is commonly found in mangrove swamps and rice paddies.

Endemic to the Ubangi (also spelled Oubangui) River drainage in southwestern Central African Republic with type locality given as ‘Small stream along Mbaiki-Mongoumba road, south of Bangui, 3°55’N, 18°10’E, Central African Republic’.

The Ubangi is is the largest right-ba…

Following the key of Romand (1992) this species can be told apart from congeners by the following combination of characters: adult size > 40 mm SL; large, dark, transverse bars and some reddish-brown pigmentation on flanks; longitudinal bands more-or-less defined; longitudinal bands composed of small red spots; caudal-fin subquadrangular caudal fin; 11-13 anal-fin rays; 16-17 dorsal-fin rays; 7-8 anal-fin rays located anterior to dorsal-fin origin.

Native to northwestern Africa with a range extending southwards from Guinea-Bissau through coastal parts of Guinea and Sierra Leone as far as western Liberia, around the city of Monrovia.

Type locality was originally given as ‘Sierra Leone’ and ‘Upper Nile’ but this was later changed to ‘Freetown, 8°30’N, 13°15’W, Sierra Leon’, referring to the capital of Sierra Leone.

P. arnoulti has been in the aquarium hobby for many years but was identified as the congener P. omalonotus prior to its description.

It appears in the majority of older aquarium literature under that name and as a result a degree of hybridisation has undoubtedly occurred.

Type locality is close to a waterfall on the Ndian River in southwestern Cameroon, and appears restricted to the coastal plains either side of the border between Cameroon and Nigeria, including the Korup and Cross River National Parks.

This species is widely-distributed in lowland, coastal regions of Togo, Benin and Nigeria as far as the Cross River delta, and occurs at some inland localities along the lower Niger River. Populations in Cameroon, Equatorial Guinea and Gabon are now considered to represent other species.
