Werneria cf. mertensiana Amiet, 1976 Photo figures 12A–B

TYPE LOCALITY.— “ Mt. Nlonako, env. de N’Kongsamba, 1.000 m ”, Cameroon .

DISTRIBUTION.— In Equatorial Guinea it is only known from Monte Alén National Park, Río Muni (De la Riva 1994) (Map 13B).

COMMENTS.— This genus was originally reported in Equatorial Guinea by De la Riva (1994) at Monte Alén National Park based on a single specimen, which was regarded as W. mertensiana Amiet, 1976 . However, Rödel et al. (2004) suggested that the taxonomic status of the Werneria species from Equatorial Guinea needs to be revised, as no morphological characters concordant with those of other congeneric species, including W. mertensiana from Cameroon, were detected.

Thus, the population from Río Muni could represent an undescribed species (Rödel et al. 2004), but more data are necessary to test this hypothesis.

SPECIMENS EXAMINED.— No specimens of Werneria from Equatorial Guinea were found in the collections examined by us in this study.
