| Distribution | S Cameroon, Gabon and Congo (Brazzaville), Equatorial Guinea Type locality: Cameroon, Campo Region, Nkoelon, 2.3972° N, 10.04515° E, 85 m |
| Reproduction | oviparous (not imputed, fide Zimin et al. 2022) |
| Types | Holotype: ZFMK 87679 (Fig. 4), adult male, collected by Michael F. Barej and Julia Wurstner on 27 October 2007. Paratypes. ZFMK 87680-82, same data as the holotype. |
| Diagnosis | Diagnosis: A medium sized species of Hemidactylus, with a max. SVL of 78 mm, a maximum total length of 174 mm, a more elongated head than the other species of the H. fasciatus group, and three enlarged internasal scales present in most specimens. It is unique in coloration by possessing body crossbands which are more narrow than the pale interspaces; the interspaces contain indistinct dark bands which are not connected at the vertebrate; by having the first body crossband restricted to the neck (vs. reaching the cranium as in the other species); by having the last crossband on the body between the legs not in contact with the hindlimbs (vs. in contact); and by having a distinctly fine narrow dark stripe on the side of the head between eye and ear, as the extension of the crossband on the neck (vs. a band slightly narrower or as broad as the crossband in the other species). |
| Comment | Relationships. This species includes all populations that cluster with those from the southern portion of the Congolian rainforest (southern Cameroon, Gabon and Congo) presented by Leaché & Fujita (2010), with strong support in the Bayesian species delimitation model. The SNP loci used by Leaché et al. (2014) provide strong support placing this taxon in a clade with H. biokoensis sp. n. Carlino & Pauwels 2015 consider H. coalescens as a synonym of H. fasciatus. Species delimitation: Douglas & Bouckaert 2022 applied a new species delimitation approach to this and other species but apparently did not infer any changes to current species definitions. Distribution: For a map with localities in Equatorial Guinea see SÁNCHEZ-VIALAS et al. 2022. |
| Etymology | This species is named after the coalescent process used to delimit the species. |
