Comments. The species is exclusively found in the northern region of the country (Hauts Plateaux and coastal area). Recent studies showed that there are several cryptic groups related to Chirocephalus diaphanus outside and inside of Algeria (Boumendjel et al. 2023; Reniers et al. 2013). Further molecular analysis is required to clarify the taxonomic status of Chirocephalus diaphanus .
