Aubria subsigillata (Duméril, 1856)

TYPE LOCALITY.— Gabon .

DISTRIBUTION.— This species is distributed in rainforests from southern Guinea and northern Liberia to Gabon. In Equatorial Guinea, it has been recorded from Río Muni at Cabo San Juan (Boulenger 1903) and Benito River (Boulenger 1900). There is also a record of this species from Bioko based on the specimen CAS 207956, tentatively idendified by Drewes et al. (1999) (Map 25B).

COMMENTS.— The specimens examined from Equatorial Guinea correspond to the longlegged form with the femoral glands half-way between knee and vent. These features correspond to A. subsigillata as stated by Ohler (1996), who also proved that A. occidentalis Perret, 1964, is a junior synonym and that the short-legged form with femoral glands closer to knees should be considered as A. masako Ohler and Kazadi, 1990 . Rödel et al. (2005) provided a summary of the taxonomic history of A. masako and A. subsigillata, and suggested that the later might comprise more than one species. Members of this genus (currently comprising two morphologically distinct species, A. subsigillata and A. masako) present a remarkable sexual dimorphism in which the secondary sexual characters characterize females (see Perret 1994): femoral glands are best developed in females, while they are smaller or absent in males. Drewes et al. (1999) suggest the possible presence of this species on Bioko based on a tentative identification of a single specimen, that is yet unconfirmed.

SPECIMENS EXAMINED.— Six specimens. Bata, Río Muni, 1966 (Nº 2694–2697); without data (B8715); Cabo San Juan, Río Muni (MNCN 3872) .
