The anuran genus Laliostoma Glaw, Vences & Böhme forms, together with Aglyptodactylus Boulenger, the subfamily Laliostominae in the endemic Malagasy-Comoran family Mantellidae. Laliostoma labrosum (Cope) is the sole representative of the genus. This stout, terrestrial frog is widely distributed in open areas of western and central Madagascar and breeds in lentic waters. It is the only mantellid without intercalary elements between terminal and subterminal phalanges of fingers and toes (Glaw & Vences 2006) and has an important potential to understand the evolution of mantellid frogs (Glaw et al. 2006). The tadpoles of L. labrosum have briefly been described by Cope (1868) and Glaw & Vences (1994), with additional detailed measurements and data on natural history published by Glos & Linsenmair (2004). As a contribution to provide reliable and detailed larval descriptions of all Malagasy frog species we here update the previous descriptions based on newly collected Laliostoma tadpoles identified by DNA barcoding (Thomas et al. 2005).

The poorly-known, insular endemic frog species, Minervarya nicobariensis (Stoliczka, 1870) is re-described based on new material from the Nicobar Archipelago. A neotype is designated as its holotype had been lost. Novel data on biology, ecology, distribution and natural history of this poorly known species are provided. Breeding biology and larval morphology are described in detail. Potential threats to the species are discussed and an assessment of its conservation status is attempted.

Behavioral Information

Several frog species descriptions from this century provide larval morphology, acoustical, molecular, ecological and behavioral information that, together, provide a better species characterization (e.g., Glos et al. 2005; Toledo et al. 2010; Vassilieva et al. 2016). For the majority of anuran species, basic information is still lacking, despite being fundamental to understand the evolution of a taxonomic unit as well as phylogenetic relationships established between taxa. Such information can be particularly useful for species groups with unresolved taxonomic issues, such as the Dendropsophus marmoratus group (Bokermann 1964; Heyer 1977; Caramaschi & Jim 1983; Gomes & Peixoto 1996).

AbstractThe tadpoles of three poorly known endemic frog species from the forested mountains of the Republic of Tanzania are described: Arthroleptides martiensseni (Anura: Ranidae), Afrixalus uluguruensis (Hyperoliidae) and Leptopelis vermiculatus (Hyperoliidae). Natural history observations are included where possible.

The South Asian spiroboloid species Xenobolus carnifex (Fabricius, 1775) is redescribed and illustrated in detail. The genus Xenobolus Carl, 1919 is diagnosed and its relationship and subfamily placement within Pachybolidae Cook, 1897 are discussed. The species Xenobolus acuticonus Attems, 1936 is synonymised with X. carnifex based on morphological and DNA barcoding data. Information on the natural history of X. carnifex is provided and its current distribution is mapped.

Biodiversity Inventories

An international consortium of major natural history museums, herbaria and other organizations has launched an ambitious project, the ‘Barcode of Life Initiative’, to promote a process enabling the rapid and inexpensive identification of the estimated 10 million species on Earth. DNA barcoding is a diagnostic technique in which short DNA sequence(s) can be used for species identification. The first international scientific conference on Barcoding of Life was held at the Natural History Museum in London in February 2005, and here we review the scientific challenges discussed during this conference and in previous publications. Although still controversial, the scientific benefits of DNA barcoding include: (i) enabling species identification, including any life stage or fragment, (ii) facilitating species discoveries based on cluster analyses of gene sequences (e.g. cox1 = CO1 , in animals), (iii) promoting development of handheld DNA sequencing technology that can be applied in the field for biodiversity inventories and (iv) providing insight into the diversity of life.

Anurans inhabiting Australia’s semi-arid and arid zones display eruptive breeding patterns. They emerge in large numbers to reproduce after significant rainfall before burrowing deep underground, where they remain concealed for extensive periods until favourable conditions return. This cryptic life history hinders documentation of the natural history and ecology of arid adapted amphibians of Australia. Fundamental information for some species such as geographic distribution thus remains uncertain. Here, we report range extensions for two species of Cyclorana. Cyclorana are a genus of 14 burrowing frog species that occupy arid, semi-arid and monsoonal regions of Australia. We document a 188 km southerly range extension of Cyclorana cryptotis, and an 88 km northerly extension for Cyclorana maini; both within the Davenport Murchison Ranges bioregion of the Northern Territory. Our observation of C. cryptotis is significant as it is the first record of the species in the Davenport Murchison Ranges bioregion.

We describe the larval stages of five frog species classified in the Madagascan subgenus Brygoomantis of the genus Mantidactylus, which were identified by DNA barcoding: Mantidactylus alutus, Mantidactylus curtus, and three taxonomically undescribed species here named Mantidactylus sp. aff. biporus "Ranomafana", M. sp. aff. biporus "Marojejy", and M. sp. aff. curtus "Ankaratra". The larvae of M. alutus, and of M. sp. aff. curtus "Ankaratra", had been described before, and we confirm and complement the previous studies. Our data confirm that Brygoomantis tadpoles are benthic, of a rather generalized body shape and oral disc morphology. All species for which tadpoles are known so far have a large dorsal gap of marginal papillae, a labial tooth row formula of 3-5 rows on the anterior labium of which only the first is continuous and the others have distinct medial gaps, and three rows of labial teeth on the posterior labium of which the first usually has a very small medial gap which however can sometimes be undetectable. Total number of marginal and submarginal papillae ranges from 50 to 103 and density of labial teeth (on the second upper row) from 19 to 76 per mm.
