| 1:46a | [Herpetology • 2022] A Review of Records of the Trimeresurus albolabris Gray, 1842 Group (Reptilia: Viperidae) from the Indian Subcontinent: Expanded Description and Range Extension of Trimeresurus salazar, Redescription of T. septentrionalis and Redisco
Abstract We revisit the identities of ‘Trimeresurus albolabris’ records from India and Nepal, based on a re-examination of historically mentioned specimens. Based on morphological congruence, we identify an old specimen originally labeled as T. albolabris from ‘Nagpur, Central Province’ as Trimeresurus salazar. We also provide new records of T. salazar based on molecular data from newly collected specimens in Central India. As the range of T. salazar is now known to approach that of its sister species Trimeresurus septentrionalis, we also redescribe T. septentrionalis based on the holotype and referred material. Finally, we examined two historical specimens from “Madras” collected during the Novara Expedition, which we identify as T. davidi, leading to a reassessment of their origin. Consequently, we remove T. albolabris from the list of Indian snake fauna. Keywrods: Reptilia, Car Nicobar, distribution, identity, Nagpur, Madras, morphology, scalation
"Our recent publication reviewed the status and distribution of so called White-lipped pit viper (Trimeresurus albolabris) in Central and Northeast India. Here, we declare that there is no White-lipped pit viper found in mainland India. Salazar's pit viper (T. salazar) is new White-lipped pit viper in mainland India." | ||||||
| 2:05a | [Botany • 2022] Phyllanthus pterocaulis (Phyllanthaceae) • A New Critically Endangered Species of Stone Breaker from Central Brazil, with Notes on its Leaf and Stem Anatomy
Abstract A new species from the state of Goiás, Brazil, Phyllanthus pterocaulis, is described and illustrated, with comments on its geographic distribution and environmental preferences, phenology, morphological relationships, and systematic position. It is morphologically allied with Phyllanthus avicularis, P. heliotropus, and P. hyssopifolioides, but differs from all of them by a set of characters related to cymules sex, presence and types of trichomes on leaves and stems, leaf consistency, numbers of sepals in flower of both sexes, integrity of stamens, capsules and seeds. Additionally, we provide images of the new species in the field, conservation status, mapped distribution, the anatomical description of its stem and leaves, and a key to differentiate it from the other similar species belonging to Phyllanthus sect. Loxopodium occurring in Brazil. The new species is one of the few in the genus that occurs in shaded environments in seasonal dry forests within the Cerrado biome. Keywords: Seasonal dry forest, Phyllanthus sect. Loxopodium, Phyllantheae, diversity, taxonomy, Eudicots
Phyllanthus pterocaulis M. J. Silva. sp. nov. Diagnosis:—This species can be differentiated from its most similar species (see table 1) by having herbaceous habit up to 13 cm tall, stem short and sparsely hispidulous, conspicuously winged in cross section, Leaves ovate with margin irregularly serrate, base truncate or cordate, hispidulous below; flowers on both sexes 5 or 6-merous, the staminate ones with three free stamens, the pistillate ones with bilobed stigma. Etymology:—The specific epithet “pterocaulis” refers to the cross section of its winged stem (“ptero” from the Greek “pterón”, plus “caulis”, from Latin).

| 7:12a | [Botany • 2017] Sonerila janakiana (Melastomataceae) • A Stoloniferous Species from India
Abstract Sonerila janakiana, a new tuberous, scapigerous and stoloniferous species of Melastomataceae collected from exposed wet rocks of evergreen and semi evergreen forests in the Nilgiris and Wayanad districts of Tamil Nadu and Kerala states on the Western Ghats in India is described and illustrated. Apart from other characteristics, it is distinguished from all hitherto known species of the genus in India by having stolons and dimorphic leaves. The stolons produced from tubers terminate and develop into new tubers producing new plants.
Sonerila janakiana Ratheesh, Sunil & Sivadasan sp. nov. A species resembling S. wallichii in general morphology, but differing by having a stoloniferous habit, up to 11 leaves, inflorescence with up to 15 flowers, glabrous peduncle, pedicel and hypanthium, urn-shaped glabrous capsules and seeds with non-excurrent raphe. It also resembles S. vatphouensis in its stoloniferous tubers and S. tuberosa in its foliar dimorphism, but strikingly differs in size, shape, structure and texture of petioles and flowers. Etymology: The epithet is proposed in honor of the late Dr E. K. Janaki Ammal, a renowned Indian botanist, in recognition of her valuable contributions in cytogenetics, phytogeography and ethnobotany and also for her service in reorganizing the Botanical Survey of India (BSI) in her initial capacity as Officer on Special Duty and later as the Director-General of the BSI. She was honored with several prestigious awards and recognitions including the award Padma Shri by the Government of India. Th e Ministry of Environment and Forests, Government of India has instituted the E. K. Janaki Ammal National Award on Taxonomy, in her commemoration to encourage and promote taxonomy in India. M. K.

| 7:23a | [Entomology • 2022] Ctenostegus hansoni • A New Species of Spider Wasp (Hymenoptera: Pompilidae) endemic to Lord Howe Island, Australia
Abstract Lord Howe Island is a UNESCO World Heritage Site with a highly endemic biota and a history of recent species extinction. During the 2017 and 2018 Australian Geographic Society expeditions to Lord Howe Island, spider wasps in the genus Ctenostegus Haupt, 1930 were collected from various sites. A new species – C. hansoni sp. nov. – is described based on this material. The external morphology and male genitalic features are illustrated for all constituents of the C. immitis species-group, for which an identification key is provided. New distribution data for the Hymenoptera of Lord Howe Island include an additional genus of Pompilidae (Fabriogenia sp.) and the first record for the family Mutillidae (Ephutomorpha sp.). Ctenostegus hansoni sp. nov. is one of the few spider wasps restricted to an oceanic island and constitutes an intriguing new record of long-distance dispersal from mainland Australia followed by speciation. Keywords: pompilid, solitary wasp, systematics, taxonomy
Ctenostegus hansoni sp. nov. Etymology: This species is described in honour of Luke Hanson, who, along with his family and the Australian Geographic Society, made the Lord Howe Island expeditions possible. Distribution: This species is known from AUSTRALIA: New South Wales: Lord Howe Island. Juanita Rodriguez and Olivia Evangelista. 2022. Ctenostegus hansoni sp. nov., A New Species of Spider Wasp endemic to Lord Howe Island (Hymenoptera: Pompilidae). Austral Entomology. DOI: 10.1111/aen.12616 | ||||||
| 1:26p | [Botany • 2016] Ceropegia nampyana (Apocynaceae: Ceropegieae) • A New Species from A midland Lateritic Hill of Kerala, India
Abstract Ceropegia nampyana, a new species of Apocynaceae from the southern Western Ghats, is described and illustrated. The new species is morphologically allied to Ceropegia spiralis Hook.f. & Thomson, but differs by having corolla lobes shorter than the tube, corolla tube glabrous within and hairy outer corona. The new taxon belongs to Ceropegia Ser. Attenuatae.
Ceropegia nampyana Manudev, Kambale & Pramod, sp. nov. Ceropegia nampyana is close to C. spiralis Wight but differs by having corolla lobes shorter than the tube, corolla tube glabrous within, hairy outer corona as opposed to corolla lobes as long as corolla tube, bulbous based conical trichomes present within tube, glabrous outer corona in C. spiralis. Etymology: This species is named in honour of Professor Santhosh Nampy, Department of Botany, University of Calicut, Kerala, for his valuable contribution to the field of Angiosperm taxonomy, who guided the first author to the field of taxonomical research.
