Three new species of Otostigmus Porat, 1876 from Brazilian Atlantic Forest are described. Otostigmus beckeri sp. n. andO. lanceolatus sp. n. are described from the state of Bahia and O. giupponii sp. n. from the state of Espírito Santo. InBrazil, the otostigmine scolopendrid genus Otostigmus comprises 22 species. A summary of Brazilian Otostigmus speciesis presented with new distribution records, taxonomic remarks when appropriate and an identification key. Otostigmus sul-catus Meinert, 1886 is recorded for the first time from Brazil; the Andean Otostigmus silvestrii Kraepelin 1903, previouslyrecorded from Brazil, is here considered not to be present in this country. Eight nominal species are regarded here as newsynonyms. Five of them—Otostigmus pradoi Bücherl, 1939, O. longistigma Bücherl, 1939, O. longipes Bücherl, 1939,O. langei Bücherl, 1946 and O. dentifusus Bücherl, 1946—are based on females of O. tibialis Brölemann, 1902. O. latipesBücherl, 1954 is conspecific with and is considered a junior synonym of O. sulcatus Meinert, 1886; O. limbatus diminutusBücherl, 1946 is a junior synonym of O. limbatus Meinert, 1886 and O. fossulatus Attems, 1928 is a junior synonym of O. goeldii Brölemann, 1898. A lectotype is designated for O. goeldii.

Land use is the human utilization for money, private, recreational, conservational and administrative purposes. The idea of land use is firmly interwoven with human network advancement. Examples of human turn of events and land use have molded the earth legitimately and internationally since ancient occasions. Current improvement designs, along with highlights of the common habitat and the outcomes of past advancement exercises, decide future advancement openings, and furthermore the requirement for rebuilding or upgrade of natural assets. North-east India is the abode of highly endemic flora and fauna preserving the pristine environment with little human interference until recent times. However, for past two decades a drastic change in the land use pattern in the region has been observed which may threaten the fragile ecological balance of the region. Tripura, known as one of the seven sisters, is a bamboo resource and second largest rubber producer in India. Tripura has the highest number of primate species found in any Indian state. However, as compared to its other sisters, the state is economically backward. The land use of the state is undergoing rapid change which is facilitated to a great extent by rapidly increasing population. The present paper deals with the changing land use of Tripura especially in the last two and a half decades. The objective of the study is to analyse the changing land use of the state in general and changes in agricultural and non-agricultural land use in particular based upon the data collected from secondary sources like Statistical Abstract of Tripura, Population Tables of Census 1991, 2001 and 2011 along with the information collected from various government websites.

Sumi (also known by its exonym ‘Sema’) is a Tibeto-Burman language spoken in Nagaland, North-east India. It is one of the major languages of the state, with an estimated 242,000 speakers living primarily in Zunheboto district, as well as in the major cities of Kohima and Dimapur. Bradley (1997) places Sumi (referred to as Sema), among the ‘Southern Naga’ languages, which include Angami (also known as Tenyidie) and Ao, in contrast to the ‘Northern Naga’ languages such as Konyak and Nocte. Burling (2003) offers a more conservative classification, placing Sumi (referred to as Simi) in an ‘Angami-Pochuri’ group containing Angami, Chakhesang (Chokri and Kheza) and Mao. Four main dialects of Sumi have been identified: the Western dialect, the Eastern dialect, the Chizolimi dialect, and the Central dialect. The Central dialect is the standard dialect used in published works of Sumi (Sreedhar 1976: 4–5).

Gnetum gnemon L. (Gnetaceae) is used traditionally for treating malaria related fever by indigenous people of North East India. In our preliminary study, the ethanol extract of G. gnemon leaves showed promising antiplamodial activity against Plasmodium falciparum chloroquine sensitive (3D7) strain in vitro with an IC50 value of 29.4 μg/mL. Therefore, it was further investigated, and by following a bioassay guided approach, 2,3-dihydroxypropyl icosanoate (1), oleic acid (2) and ursolic acid (3) were isolated for the first time from this plant. Compound 3 showed highest antiplasmodial activity with IC50 values of 4.0 and 6.0 μg/mL against chloroquine sensitive (3D7) and resistant (Dd2) strains of P. falciparum, respectively. The antiplasmodial activity of 1 (IC50 9.5 and 11.4 μg/mL) and 2 (IC50 17.6 and 21.1 μg/mL) was moderate. The isolated constituents showed low cytotoxicity against rat skeletal muscle (L6) and human cervical cancer (HeLa) cells. This is the first report on the antimalarial potential of G. gnemon and the isolated compounds may be responsible for its activity. The findings of the study are in line with the ethnopharmacological claim and can be possible leads for future studies.

Chromosomal study conducted in nine species of Dioscorea from different forest belts of Tripura revealed that their somatic chromosome number ranged from 2n=40 to 2n=60. The record of 2n=40 chromosome in the sexual phenotypes of Dioscorea hamiltonii, Dioscorea glabra and Dioscorea pubera are the first time report from Tripura, North East India. Moreover the somatic chromosome counts of 2n=60 in Dioscorea pentaphylla would be attributed as a new cytotype. However at the respective ploidy level no difference in somatic chromosome count was observed between their sexes.
