The imagery on this page is the subject of a paper entitled A new frog family (Anura: Terrarana) from South America and an expanded direct-developing clade revealed by molecular phylogeny by M.P. Heinicke, W.E.Duellman, L. Trueb, D.B. Means, R.D. MacCulloch, and S.B. Hedges (Zootaxa, 2211, 1-35, 2009). The abstract is as follows:

Three frogs of a new species found in cloud forests on two nearby mountains in Guyana were included in a molecular phylogeny of 17 nuclear and mitochondrial genes (10,739 aligned sites) that revealed that their closest relative is Terrarana (Brachycephalidae, Craugastoridae, Eleutherodactylidae, and Strabomantidae) and their next-closest relative is Hemiphractidae (marsupial frogs). We place these frogs in a new family, genus, and species which is strongly supported as the basal clade within Terrarana: Ceuthomantidae n. fam., Ceuthomantis smaragdinus n. gen, n. sp. Morphological evidence supports the placement of two other species from the Guiana Highlands, Pristimantis aracamuni (Barrio-Amorós & Molina) and P. cavernibardus (Myers & Donnelly), in the new family and genus. This close phylogenetic relationship of terraranans and marsupial frogs, nearly all of which have direct development, supports an hypothesis that direct development evolved early in the evolution of this huge clade (~1000 species), for which we propose the unranked taxonomic epithet Orthobatrachia.

This specimen was collected 4.2 km north of Hardwar Gap, Portland Parish, Jamaica on 31 May 1983. It was scanned at the Center for Quantitative Imaging at Pennsylvania State University for Dr. Blaire Hedges.

The specimen was scanned with an interslice spacing of 0.028 mm, an interpixel spacing of 0.026 mm, and a 26.6 mm field of view.
