2:31p	[Botany • 2024] Glochidion yangchunense (Phyllanthaceae) • A New Species with discoid flowers from Guangdong Province, China    Glochidion yangchunense Z.Q. Song & Gang Yao,  in Song et Yao, 2024. DOI: 10.3897/phytokeys.239.118411 Abstract Phyllanthodendron can be readily morphologically distinguished from Glochidion, but recent molecular evidence showed that Phyllanthodendron is paraphyletic due to Glochidion being nested within it. In this study, a new species of the former Phyllanthodendron is described and illustrated as Glochidion yangchunense Z.Q. Song & Gang Yao from the limestone areas of South China. This is a peculiar new species and morphologically distinguished by its discoid flowers, T-shaped disc segments, and glabrous flowering branches. A key to Glochidion yangchunense and related species in China is provided here. Key words: Karst, Malpighiales, Phyllantheae, Phyllanthodendron, Taxonomy Glochidion yangchunense Z.Q. Song & Gang Yao  A habit B detail of the apex of branches C fruiting branches D, E leaves, adaxial and abaxial surfaces, shapes and sizes F, G pistillate flower, front and lateral view H, I staminate flower, front and lateral view J branches with staminate and pistillate flowers as well as fruit K fruits and seeds. Arrows indicate disc segments.  Glochidion yangchunense Z.Q. Song & Gang Yao, sp. nov. Diagnosis: Glochidion yangchunense resembles Glochidion anthopotamicum (Hand.-Mazz) R.W. Bouman in general morphology, but much differs from the latter by its glabrous flowering branches (Fig. 1G, I) (vs. pubescent flowering branches; Fig. 3C–F), sepals with lateral veins (Fig. 1F, H) (vs. sepals without lateral veins; Fig. 3D–F), sepals jointly formed a discoid shape (Fig. 1F–I) (vs. sepals jointly formed a urceolate shape; Fig. 3D–F), T-shaped disc segments (Fig. 1F, H) (vs. linear disc segments; Fig. 3D), and short stipules (ca. 1 mm vs. 3 mm long). Related species of Glochidion yangchunense Z.Q. Song & Gang Yao A–F Glochidion anthopotamicum (Hand.-Mazz.) R.W. Bouman G–L Glochidion dunnianus (H. Lév.) R.W. Bouman A, G habit B, H, I branches C–F, J–L flowers, front and lateral view H part of winged branch with stipules D, K pistillate flowers E, F, L staminate flowers. White arrows indicate disc segments and red arrow indicates stamen. Etymology: The specific epithet refers to the type locality, Yangchun City in Guangdong Province, China, a hotspot for biodiversity research in Guangdong Province, where multiple new taxa of plant ... have been described (see Song et al. 2023).

3:39p	[Herpetology • 2024] Cnemaspis chandoliensis, C. sahyadriensis, etc. • A preliminary Taxonomic Revision of the girii clade of South Asian Cnemaspis Strauch, 1887 (Squamata: Gekkonidae) with the Description of Four New Species from southern Maharashtra, In  Cnemaspis barkiensis, C. chandoliensis,  C. maharashtraensis and C. sahyadriensis  Khandekar, Gaikwad, Thackeray, Gangalmale & Agarwal, 2024 DOI: 10.11646/zootaxa.5429.1.1   facebook.com/AkshayKhandekarAK Abstract The girii clade is the most diverse clade of South Asian Cnemaspis in the Northern Western Ghats, including ten valid species. Recent collections of four divergent lineages from southern Maharashtra prompted us to examine the type material of all species in the girii clade, which led to the discovery of numerous errors and discrepancies in the literature. We take this opportunity to provide an updated and expanded morphological dataset including diagnoses and comparisons for all species of the girii clade and to build an almost complete species-level phylogeny including the first ND2 sequences of C. rajgadensis and C. uttaraghati, as well as the four new species described herein (but excluding C. fortis). We describe the four divergent mitochondrial lineages as new species using morphological data, and provide a key to species of the girii clade. Finally, we list some inconsistences in previous publications and data for the girii clade.

We have named one of the four new species Cnemaspis barkiensis, after the type locality, Barki Reserve Forest in Kolhapur District. The remaining three new species were found in the Chandoli National Park in Sahyadri Tiger Reserve, and we have named them Cnemaspis chandoliensis (after the Chandoli National Park), Cnemaspis maharashtraensis (after the Maharashtra State), and Cnemaspis sahyadriensis (after the Sahyadri Tiger Reserve and Sahyadri Mountain Range). All four new species are endemic similar to other members of their genus, and are currently known only from around their respective type localities.  ..."   Akshay Khandekar, Sunil M.
