(2010); Lotzkat et al. (2010: referring to SMF 89963). Holotype. Adult female SMF 50951, original field number AB 1241 (Fig. 12) collected in leaf-litter 500 m east of the village Chicheme (8.865278 °N, 80.643829 °W, 100 m elev.), San José del General, Donoso district, Colón province, Panama, collected on 25 January 2013 at 11: 40 hrs by Abel Batista, Lester Vásquez, and Leysi Díaz. Paratypes. Four adult males, all from Panama: SMF 89963 from Cerro Negro, Veraguas, on 28 July 2008; SMF 50950 (collected on 20 July 2011), 50952, and MHCH 2954 from Petaquilla, Coclé del Norte, Donoso, Colón; see Appendix I for locality details. Diagnosis. Lepidoblepharis victormartinezi (our sp. nov. 3) is characterized by the following combination of characters: (1) dorsal scales small, granular, and juxtaposed, ventral scales large, cycloid, flat, and imbricate; (2) scales on head small and granular; (3) 3–5 (4.4 ± 0.89) postrostrals; (4) two paramedian clefts demarcate the slightly convex median portion of the posterior mental border, rendering the latter vaguely M-shaped in its totality; (5) 5–7 (6.0 ± 0.71) postmentals; (6) lamellae under fourth toe 6–8 (6.6 ± 0.89), lamellae under fourth finger 4–5 (4.8 ± 0.45), the subdigital lamellae under each digit showing a peculiar morphology that is unique within the genus, with 1–3 proximal one(s) longitudinally greatly enlarged, each about 3–4 times longer than any of the remaining lamellae; (7) median subcaudals only slightly larger than the neighboring scales, about as [...]

Panama is a hotspot of amphibian and reptile diversity and many areas of the country still remain underexplored. Here we present results of our field work carried out through several years in western Panama, further increasing the numbers of amphibian and reptile species known from the country. We provide the first country records for Smilisca manisorum and Lepidophyma reticulatum. Additionally, we extend the known distributional ranges of Pristimantis taeniatus, Pleurodema brachyops, Leptodactylus fuscus, Bachia blairi, Basiliscus plumifrons, Anolis auratus, A. capito, A. cryptolimifrons, A. humilis, A. kemptoni, A. pseudopachypus, Geophis godmani, Mastigodryas pleei, and Bothriechis supraciliaris.

Ethanol extracts from Oophaga pumilio specimens collected in western Panama (4 populations) and southern Nicaragua (two populations) were analyzed for their alkaloid composition by gas chromatography-mass spectrometry. High variability in the alkaloid profiles among the various populations as well as among individual specimens from Panama and Nicaragua were observed. Since alkaloids in dendrobatid frogs and other anurans are of dietary origin, the various alkaloid profiles found are not representative for certain populations, but are indicative for the availability of prey (mites, ants and other arthropods) containing these chemical compounds selected as food by the frogs in their habitats.

Pristimantis gretathunbergaesp. nov. is a sister species to the allopatric P. erythropleura-penelopus group from northern Colombia with a mtDNA sequence divergence of > 4.4% at 16S and > 14.6% at COI. Its closest congener in sympatry is P. cruentus that differs by a large sequence divergence of > 9.6% in 16S mtDNA and 19.0% at COI, and from which it differs also by ventral and groin coloration, unusually prominent black eyes, a contrasting light upper lip, commonly a single conical to spine-like tubercle on the upper eyelid, and a larger head. While the habitat continuity at most sites in eastern Panama is moderate, habitats in central Panama are severely fragmented. Cerro Chucantí and the surrou...
