In an effort to assess the current geographic distribution of the critically endangered frog Telmatobufo bullocki Schmidt, 1952, we conducted several field surveys in the Nahuelbuta mountain range in central-south Chile. We surveyed historic localities cited in the literature, and potential new localities in private forestry areas. Telmatobufo bullocki was found in six localities: four historic and two new. The discovery of new populations and the confirmation of the persistence of the species in at least four historic localities open new perspectives for the conservation of this threatened species.

New northwestern records of the striped treefrog Hypsiboas caingua (Carrizo, 1991 “1990”) are presented for Brazil, extending its known geographic distribution approximately 115 km northward (linear distance) of the previous northernmost record of the species. In all new localities, individuals of H. caingua were only found in calling activity under temperatures below 18°C. The species appears to be associated with Atlantic Forest, although it had already been recorded in Cerrado. Although the scientific literature data suggests that H. caingua presents discontinuous geographical distribution, three methods of distribution modelling based on climatic data show that the species' distribution is continuous. The gap in the distribution may be related to the lack of field surveys in the regions that connect these populations, especially in colder periods. Nevertheless, factors other than climate might also be responsible for the current distribution of H. caingua, since the species was absent in well-surveyed sites situated between the areas of modeled distribution. Therefore, further studies on natural history, populations' genetic structure, and geographic distribution models implementing factors other than climate will be important to elucidate some ecological and evolutionary aspects of the distribution of H. caingua in South America.

We report new localities for Anolis pseudokemptoni Köhler, Ponce, Sunyer & Batista, 2007, along the Serranía de Tabasará in the Comarca Ngöbe-Buglé of western Panama. These records extend the known geographic distribution of this lizard about 6 km eastward and 9 km northwestward, as well as the known vertical distribution approximately 470 m lower and 380 m higher. We also provide photos of specimens from different localities and comment on their morphology. No population of this Panamanian microendemic species, which is classifiable as Critically Endangered, lives inside a protected area.

Nannophrys marmorata is a critically endangered species of frog known only from a few locations in the Knuckles Conservation Forest (KCF) in the Knuckles mountain range of Sri Lanka. Here, we report new localities outside its known range in the KCF and examine the distribution of N. marmorata providing the most extensive distribution map for this species. Furthermore, using the distribution information, we model the fundamental ecological niche of this species through Ecological Niche Modeling (ENM) to predict suitable habitats and fine-scale distribution patterns. ENM predicted eastern slopes of the Knuckles mountain range in central Sri Lanka as areas with high habitat suitability (suitability 75%) for N. marmorata. Predicted Extent of Occurrence for N. marmorata was 831 km2 and predicted Area of Occupancy was 275 km2. We discuss these findings in light of conservation for this species threatened with extinction.

A New Species

To date, only one species of Temnocephala is known from Chile, Temnocephala chilensis, and three from southern Argentina (Patagonia), namely T. chilensis, Temnocephala dionii, and Temnocephala mexicana. Here we describe a new species of Temnocephala and provide an updated description of T. chilensis based on material found on an anomuran crab (Aeglidae) from southern Chile. Additional hosts and localities are reported for both species in southern Argentina and Chile, and a diagnostic key for all species of Temnocephala hosted on Aegla and Parastacidae is included as well. In southern Chile, both T. chilensis and the new species were found on the crayfish Samastacus spinifrons and on the anomuran crabs Aegla abtao and Aegla alacalufi; in addition, the new species was found on Aegla manni, and T. chilensis on Aegla rostrata. In southern Argentina, T. chilensis and the new species were found on Aegla riolimayana and S. spinifrons. Based on their shared traits (morphology of the penial stylet, host preferences and geographic distribution), the temnocephalans hosted in Aegla are tentatively gathered into two clusters, the Chilensis and Axenos groups.

Digitaria Eriantha

Natural hosts of pangola stunt virus (PaSV) in eastern Austalia were found to be Digitaria eriantha ssp. pentzii (pangola grass), D. ciliaris (summer grass) and D. milanjiana. Transmission tests using the planthopper vector, Sogatella kolophon, showed that D. polevansii, D. eriantha ssp. eriantha, D. swazilandensis and the Australian native, D. divaricatissima were also susceptible, whereas D. didactyla was not infected. In tests of 22 species in 15 other genera, only Urochloa panicoides (annual urochloa grass) was infected. In field surveys, PaSV was commonly found in pangola grass in near-coastal districts from Grafton, N.S.W. to Walkamin, N. Qld and was detected up to 100 km inland at Toowoomba. The virus was not detected in either pangola grass or D. eriantha ssp. eriantha in subhumid areas west of Toowoomba or at Gayndah. Sogatella kolophon was collected from Bamaga, N. Qld to Murwillumbah, N.S.W. It was commonly associated with both PaSV-infected and PaSV-free digitgrass pastures. It is concluded that PaSV poses a threat to many digitgrasses in near-coastal districts of Qld and subtropical N.S.W., but so far is unknown in inland Australia.

Extensive field surveys of the Critically Endangered Central and Eastern Rûens Shale Renosterveld have uncovered that Notobubon striatum, as currently circumscribed, comprises two distinct species. Upon careful examination of the type material it has become clear that names exist for both species. The type specimen of N. striatum clearly matches the lesser known species, a large shrub, ca. 1 m. tall, with a powerful anise-scent and which is restricted to the banks of seasonal rivers and watercourses in the Central and Eastern Rûens Shale Renosterveld. The second and better known entity, with a wider distribution, corresponds to the type material of Dregea collina Ecklon & Zeyher. As such, a new combination, Notobubon collinum (Ecklon & Zeyher) Magee, is here made to accommodate this taxon, restricted to dry quartz and silcrete patches or outcrops in Eastern Rûens Shale Renosterveld. In their revised circumscriptions N. striatum and N. collinum are readily distinguished by habit, scent, leaf size and division, as well as leaf lobe shape and sepal size. Comprehensive descriptions of both species are provided, together with notes on their ecology and conservation status, and the existing key to the species of Notobubon updated. This brings the number of recognised species in the genus to thirteen.

Abstract Phyllodytes tuberculosus is a bromeligenous anuran species whose geographic distribution is restricted to areas of the Caatinga and to transition zones between Caatinga and Atlantic Forest in the central-south of the state of Bahia. Its existence in close relationship with bromeliads and its occurrence in dry and highly seasonal environments drove us to the supposition that species is opportunistic/generalist regard to diet. We collected the items present in the stomach of 43 P. tuberculosus individuals with stomach-flushing method. Of these, 18 stomach contents were obtained during the dry period (April–October), and 25 during the rainy period (November–March). We recorded nine classes of prey, finding the greatest relative importance for the categories Formicidae and Coleoptera in dry season and Blattodea (Termites), Formicidae and Coleoptera in the rainy season. Phyllodytes tuberculosus presented a varied, possibly opportunistic diet in semiarid environments. Additionally, we report an apparent temporal differentiation related to the typical Caatinga seasonality. This study adds to the data on the natural history of an anuran species adapted to a semiarid environment with a narrow geographic distribution.
