A Rare Cleptoparasitic Bee Tetralonioidella himalayana (Bingham, 1897) (Hymenoptera: Apidae) from India: Review and New Data. NATIONAL ACADEMY SCIENCE LETTERS. NATIONAL ACADEMY OF SCIENCES, INDIA 2023; 46:1-6. [PMID: 37363280 PMCID: PMC10071265 DOI: 10.1007/s40009-023-01243-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/11/2022] [Revised: 03/13/2023] [Accepted: 03/15/2023] [Indexed: 04/07/2023]
Abstract
Tetralonioidella Strand 1914 is a very rare apid genus globally, of which only two species, Tetralonioidella himalayana (Bingham, 1897) and Tetralonioidella tricolor (Lieftinck, 1972), are known from India. They are known to be cleptoparasitic on species of Habropoda Smith, 1854 and Elaphropoda Lieftinck, 1966. During hymenopteran survey in Arunachal Pradesh, we encountered Tetralonioidella himalayana (Bingham, 1897) and observed their behavioral regime, which is very poorly known. The identifying characteristics of both male and female, their foraging behavior, floral preference, distribution pattern, and possible host association have been studied. Exclusive floral association and host specialization are potential contributing factors to the rarity of T. himalayana. Such factors may limit the distribution range of the species. A priori sampling resolution with genetic and demographic exploration is required to evaluate the present status of such bee species.

Abstract
A new genus and new species of Atalophlebiinae, Klugephlebia kodai Selvakumar, Subramanian & Sivaramakrishnan, are described based on male and female imagos and larvae from Palni hills of the southern Western Ghats of India. The imago of Klugephlebia gen. n. can be differentiated from all other genera of Atalophlebiinae by having the combination of vein MP forked slightly less than half of the distance from base to margin, MP2 attached at base to vein MP1 by a crossvein, a distinctive shape of the hindwing, dissimilar claws on each leg, and distinctive genitalia structures. The larva can be distinguished from other Atalophlebiinae larvae by having the combination of gills present on abdominal segments 1-7, dorsal and ventral portions of lamellae of gills 1 slender and lanceolate with branched tracheae, dorsal and ventral portions of lamellae of gills 2-7 wider & lanceolate and long & suddenly tapering at apex, fore and mid femora with regular rows of long thin setae on outer margins, denticles on claws progressively larger apically, a distinctive labrum, the maxillary palp short with long setae on third segment, and the third segment of the labial palp with distinct setation. The larvae cling to the underside of boulders in the middle of streams where the boulders lie amidst sand and silt. Updated keys to the genera of south Indian Leptophlebiidae are provided.

Adsorptive removal of dye using biochar derived from residual algae after in-situ transesterification: Alternate use of waste of biodiesel industry. JOURNAL OF ENVIRONMENTAL MANAGEMENT 2016; 182:187-197.

Abstract
The primary aim of this present study was to utilize the residual biomass (DB) of Spirulina platensis algae, left after in-situ transesterification, for biochar preparation. This is a solid waste residue of biodiesel industry. The biochar (BC) prepared was examined for its capacity to adsorb congo red dye from the aqueous solution. The results were compared with other adsorbents used in the study such as commercial activated carbon (AC), original algae biomass (AB) and DB. The results of proximate analysis of BC showed the decrease in the percentage of volatile matter and an increase in fixed carbon content compared to DB. The physico-chemical properties of BC were studied using elemental analysis, SEM, FTIR and XRD techniques. The AC and BC adsorbents showed better performance in removing 85.4% and 82.6% of dye respectively from solution compared to AB (76.6%) and DB (78.1%). The effect of initial dye concentration, adsorbent dosage and pH of solution on the adsorption phenomena was studied by conducting the batch adsorption experiments. The highest specific uptake for biochar was observed at acidic pH of 2 with 0.2 g/100 ml of adsorbent dosage and 90 mg/l of initial concentration. The equilibrium adsorption data were fitted to three isotherms, namely Langmuir, Freundlich and Temkin. Freundlich model proved to show the best suited results with value of correlation coefficient of 99.12%. Thus, the application of DB for production of biochar as potential adsorbent supports sustainability of algae biodiesel.

Abstract
Two new species of water striders in the genus Pleciobates are described from India and compared with allied species. Pleciobates bengalensis Jehamalar, Basu & Zettel sp. nov. is described from the Jalpaiguri District, West Bengal and Pleciobates expositus Jehamalar, Chandra & Zettel sp. nov. (Hemiptera: Gerridae) is described from the Dhubri District, Assam. A key to the species of Pleciobates and a distribution map of the species of Pleciobates from India are provided. For the first time the genitalia of Pleciobates females are described in detail.

Abstract
Amemboa mahananda sp. nov. and Amemboa bifurcata sp. nov. are described from Mahananda Wildlife Sanctuary, in the Darjeeling district and from Kalikhola, in the Jalpaiguri district of West Bengal, and compared with all allied species. A species checklist of the genus Amemboa Esaki, 1925 and Amemboides Polhemus & Andersen, 1984 from India and their distribution in India and elsewhere is provided. Amemboa kumari (Distant, 1910) is reported for the first time from West Bengal and Amemboa dentata Polhemus & Andersen, 1984 is newly recorded from Himachal Pradesh.

Abstract
The status and distribution of Idionyx Hagen, 1867 (Odonata: Corduliidae), of the Western Ghats, India, is updated and a new species Idionyx gomantakensis is described and illustrated based on male and female specimens from Kulem (= Collem), Goa, India. This new species can be differentiated from other species of Idionyx by long and slender cerci and epiproct, absence of teeth in the basal half of the cerci, and a tuft of golden hairs at the end of the lateral lobes of the epiproct. A revised key to the species of the genus is provided, and its diversity and ecology in the Western Ghats is discussed.

Caste and sex specific olfactory glomerular organization and brain architecture in two sympatric ant species Camponotus sericeus and Camponotus compressus (Fabricius, 1798). ARTHROPOD STRUCTURE & DEVELOPMENT 2009; 38:485-497. [PMID: 19539048 DOI: 10.1016/j.asd.2009.06.001] [Citation(s) in RCA: 46] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/10/2008] [Revised: 05/31/2009] [Accepted: 06/08/2009] [Indexed: 05/27/2023]
Abstract
We use monoclonal antibodies against synaptic proteins and anterograde tracing with neurobiotin to describe the architecture of the antennal lobes in different castes of two ant species -Camponotus sericeus and Camponotus compressus. The reproductives and worker classes are readily categorized based on size and external morphology. The overall organization of brain neuropile is comparable between castes with differences only in the visual ganglia. Males have a larger fraction of neuropile occupied by the medulla and lobula than females. In the diurnal species, C. sericeus these regions are more highly represented, than in the nocturnal species C. compressus. The most striking differences are in the antennal lobe where males possess a macroglomerulus, which is about ten times larger in volume than the other glomeruli; such a specialization is absent in females. Minor workers possess a significantly larger number of glomeruli than the majors despite the smaller overall volume of the lobe. These caste-specific differences occur mainly within glomerular clusters that receive input from sensory neurons that project in tracts - T4 and T5 - within the antennal nerve. The comparative anatomy of different castes of ants provides an entry point into a future systematic analysis of how divergent brain architectures can arise within a single species.
