Despite the amount of data on different aspects of biodiversity, such as species distributions, taxonomy, or phylogenetics, there are still significant gaps and biases in the available information. This is particularly true for life history traits, with fragmentary data for most taxa, especially those with complex life cycles. Anurans (frogs and toads) show larval (premetamorphic) stages that are in general radically decoupled from adult forms in most biological aspects. Our understanding of this group is highly uneven, as the main wide-scope investigations focus on adult specimens and larval stages remain unknown for a significant part of the anuran tree. The main purpose of this work was to estimate the extent of knowledge gaps regarding the diversity of tadpoles, interpret their biological and geographical patterns, and discuss possible explanations and implications for other large-scale analyses. Our findings show that more than half of the anuran species described to date still lack information on their embryonic/larval stages. Furthermore, knowledge varies among taxonomic groups, larval ecomorphological guilds, and world ecoregions. Description percentages generally decrease in lineages with a higher proportion of species known or suspected to have endotrophic development. Also, geographic areas with the highest levels of ignorance in larval biology (Tropical Andes and New Guinea) coincide with the highest diversity of endotrophic guilds. Among exotrophic larvae, generalized lentic-lotic tadpoles have the widest distribution and levels of knowledge, whereas specialized lotic, fossorial, and terrestrial forms are more taxonomically and geographically restricted. Further large-scale analyses on tadpole biology are crucial for their impact in varied scientific disciplines including anuran conservation. At a conceptual level, the discussion of the anuran biphasic life cycle is pertinent in the context of shortfalls of biodiversity knowledge and their interrelationships.

“…Additionally, a rich diversity in bats has also been documented in the region [15]. In the recent decade, several new vertebrates including six fishes [16,17], three snakes [18][19][20], and four amphibians [21][22][23][24] were described from the Langbiang Plateau. Across the plateau, cryptic genetic diversity was also detected in the frog genus Leptolalax [25].…”

Langbiangia, a new genus of Gesneriaceae endemic to Langbiang Plateau, southern Vietnam and a taxonomic endeavor to achieve key targets of the post-2020 global biodiversity framework

Situated in the southern end of the Annamite Mountain Range, Langbiang Plateau is a major biodiversity hotspot of southern Vietnam known for high species diversity and endemicity. To achieve effective conservation, parts of the plateau were designated as the Langbiang Biosphere Reserve, an UNESCO World Network aiming to improve relationships between inhabitants and their environments. Amongst the rich endemic flora of the plateau are three gesneriads ascribed to Primulina, a calciphilous genus with high species diversity in the vast limestone karsts stretching from southern China to northern Vietnam. However, a recent phylogenetic study questioned the generic placement of the Langbiang Primulina, corroborating with observations on the geographical distribution, habitat preference, and phyllotaxy of the three species. Based on phylogenetic analyses of nuclear ITS and plastid trnL-F DNA sequences of a comprehensive sampling covering nearly all genera of the Old World Gesneriaceae, we demonstrate that the three Langbiang Primulina species form a fully supported clade distantly related to other Primulina. As this clade is biogeographically, ecologically, morphologically, and phylogenetically distinct worthy of generic recognition, we propose to name it Langbiangia gen. nov. to highlight the rich and unique biodiversity of the Langbiang Plateau. By means of this taxonomic endeavor, we are hoping to raise the conservation awareness of this biodiversity heritage of southern Vietnam and promote the importance of Langbiang Biosphere Reserve that is crucial for achieving action-oriented global targets of the post-2020 global biodiversity framework (GBF) of the UN Convention on Biological Diversity (CBD)—effective conservation and management of at least 30% of biodiverse terrestrial, inland water, and costal and marine areas by 2030—that has been agreed at the COP15 in Montréal in December 2022.

“…The amphibian genus Micryletta Dubois, 1987 (family: Microhylidae), commonly referred to as paddy frogs, is a relatively small genus comprising twelve species, namely M. aishani Das, Garg, Hamidy, Smith and Biju, 2019; M. dissimulans Suwannapoom, Nguyen, Pawangkhanant, Gorin, Chomdej, Che and Poyarkov, 2020; M. erythropoda (Tarkhnishvili, 1994); M. hekouensis Liu, Hou, Mo and Rao, 2021; M. immaculata Yang and Poyarkov, 2021; M. inornata (Boulenger, 1890); M. lineata (Taylor, 1962); M. melanops Poyarkov, Nguyen, Yang, and Gorin, 2021; M. menglienica (Yang and Su, 1980); M. nigromaculata Poyarkov, Nguyen, Duong, Gorin and Yang, 2018; M. steinegeri (Boulenger, 1909); and M. sumatrana Munir, Hamidy, Matsui, Kusrini and Nishikawa, 2020. These small-sized terrestrial frogs range from northern Sumatra through the Malay Peninsula, Indochina, southern China (Yunnan and Taiwan), and northeastern India (Frost 2021).…”

The genus Micryletta, also known as paddy frogs, ranges across much of south, east, and southeast Asia. Due to their relatively broad distribution and overall morphological similarities, many species have gone undetected until recently, largely owing to the use of molecular data. Consequently, the species diversity within this genus has quadrupled in just three years from three species prior to 2018, to 12 species in 2021, indicating that the systematics of this genus is still poorly understood. As such, we assembled the most comprehensive molecular phylogeny of Micryletta hitherto including novel sequences from a previously unsampled population from Singapore to assess the species diversity within this genus. In particular, we investigate the population from Singapore whose specific identity remains in question due to the lack of voucher specimens and genetic material. Our results show that the Singapore population represents a strongly supported and distinct lineage that is most closely related to M. inornata sensu stricto from Sumatra, Indonesia. Morphological and species delimitation analyses corroborate its distinction as a new species, which we describe herein as M. subaraji sp. nov. This and recent new taxon discoveries in Singapore demonstrate that the biodiversity of the highly urbanized island-state is still far from being fully realized and underscores the need for continued systematic surveys and protection of remaining habitats.
