Surprisingly, recent inventories carried out at the

rapids near
|
||
<normalizedToken originalValue="Booué">Booue</normalizedToken>

in 2019, 2020, and 2021 did not allow to rediscover this species at this site, though having been collected there in 1966 by Nicolas
|
||
<normalizedToken originalValue="Hallé">Halle</normalizedToken>
|

and Annick Le Thomas, and then noted as being abundantly present. Nevertheless, recent inventories revealed its presence in the

over time, which shares the same micro-habitats and was recently noted as very abundant at

<normalizedToken originalValue="Booué">Booue</normalizedToken>

was not recently collected at
|
||
<normalizedToken originalValue="Booué">Booue</normalizedToken>
|
||
, its absence from this large area of rapids (ca 550
|
||
<normalizedToken originalValue="×">x</normalizedToken>
|

900 m), difficult to access in their entirety, is not certain. This site does not seem to have suffered from any particular human-induced impact, but it is yet unknown whether past stochastic events (such as exceptional natural disturbances of the seasonal variations of water levels) may have favoured one species over another. It is also possible that in such a dynamic environment, natural species replacement may occur without any human-induced impact or natural stochastic extreme climatic events. Long-term surveys of selected areas should be designed to explore these questions, and the
