Comprehensive Study

Dipterocarpus cornutus Dyer is commonly known as ‘keruing’. It belongs to the family of Dipterocarpaceae, an important timber family in South East Asia. D. cornutus is listed as critically endangered on IUCN Red List. Since no comprehensive study has been documented on the chemical constituents of D. cornutus, there is an urgent need to study this plant comprehensively. Phytochemical study of the stem bark of D. cornutus afforded a new flavonoid (1) and nine known compounds, which consist of flavonoids (2, 3), oligostilbenoids (4, 5, 7, 8, 9, 10), and coumarin (6). The finding of the study contributes to the chemotaxonomic differentiation in the plants of the tribe Dipterocarpae.

The type species of the genus Acidiella Hendel is A. longipennis Hendel, which is known as a widely distributed species in South East Asia. Specimens of A. longipennis are rarely found in insect collections, but I was able to examine a number of Myanmar specimens collected by R. Malaise during the Swedish Expedition in 1934, and reported as A. longipennis by M. Hering in 1938. As a result, three related species were sorted out from these specimens. They look very much alike except for the dorsal abdominal patterns (difficult to see in dried specimens) and postabdominal structures. I here provide detailed descriptions of and a key to A. longipennis, A. spinipenis, sp. nov., and A. kambaitiensis, sp. nov. They are here defined as the A. longipennis species group based on a single synapomorphy: vesica of glans ventrally with 7–9 tiny spines. This is a unique characteristic never found in any other species of the tribe Trypetini as well as the family Tephritidae. I am providing this information as a starting point to refine the currently confused concept of the genus Acidiella.

Molecular Phylogenetic

The laniatorean family Phalangodidae has been largely reduced to a core of Holarctic species; however, many taxa were never formally transferred to other families. We examined a group of harvestmen related to Beloniscus Thorell, 1891, from South-east Asia and determined the nature of the relationships of the ‘Beloniscus-like harvestmen’, herein described as the new family Beloniscidae, fam. nov., in the broad context of Laniatores. Based on a molecular phylogenetic analysis of a broad representative laniatorean Sanger-sequences dataset we found support for our taxonomic hypotheses that (1) inclusion of Beloniscidae, fam. nov. in Phalangodidae would render the family non-monophyletic, and (2) Beloniscidae, fam. nov. represents a lineage that is morphologically and genetically distinct from all other known laniatorean families. The new family Beloniscidae is endemic to South-east Asia and comprises 37 species in two new subfamilies: Beloniscinae, subfam. nov. and Buparinae, subfam. nov. Beloniscinae includes the genera Beloniscellus Roewer, 1931, Beloniscops Roewer, 1949, Belonisculus Roewer, 1923, Beloniscus (type genus) and Kendengus Roewer, 1949. Buparinae includes the genera Buparellus Roewer, 1949, Bupares Thorell, 1889 (type genus) and Buparomma Roewer, 1949. Members of Beloniscidae are relatively homogeneous in their external morphology, but are recognised by well marked genitalic features. Male genitalia are described for exemplar species, and the morphology is compared with that of Epedanidae. Names are given to two new genitalic structures: sella curulis and pseudocalyx. http://zoobank.org/urn:lsid:zoobank.org:act:540BCE49-6F2E-4372-BFD4-D3C6068F045D http://zoobank.org/urn:lsid:zoobank.org:act:FE8B011B-AA6D-4E6C-A321-123542A0563F http://zoobank.org/urn:lsid:zoobank.org:act:E4A559CD-170A-40F2-924A-541C22974344

Guggulu is an oleo-gum resin which exudes out as a result of injury from the bark ofCommiphora wightii(Arnott) Bhandari [syn.  Commiphora mukul(Hook. Ex Stocks) Engl;Balsamodendron mukul(Hook. Ex Stocks); Family, Burseraceae]. It has been used in theAyurvedasince time immemorial for the treatment of variety of disorders such as inflammation, gout, rheumatism, obesity, and disorders of lipids metabolism. It is a mixture of phytoconstituents like volatile oil which contains terpenoidal constituents such as monoterpenoids, sesquiterpenoids, diterpenoids, and triterpenoids; steroids; flavonoids; guggultetrols; lignans; sugars; and amino acids. This review is an effort to compile all the information available on all of its chemical constituents which are responsible for its therapeutic potential. The wild occurrence of this species is restricted mainly to the dry regions of Rajasthan and Gujarat States of India, and the bordering regions of Pakistan. Oleo-gum resin, guggulu, tapped from the stems of this species, is consumed in high volumes by the Indian herbal industries. There has been a decline in its wild population over the last several decades, as a result of habitat loss and degradation, coupled with unregulated harvesting and tapping of oleo-gum resin. This species is consequently assessed as Critically Endangered and enlisted in the IUCN red list of threatened species.

IN October 1948, the Governor of Hong Kong appointed a committee to consider the position of Chinese law and custom in that colony. The report of this committee, which was published in February 1953,1 will have drawn attention to the fact that the old family law of China, quite apart from the limited recognition given to it by the courts, continues to exercise considerable influence on the lives of millions of Chinese, not only in Hong Kong, but in the other British territories of South-East Asia. In China itself, as regards matters of the family, the Civil Code of the former National Government had never, over most of the country and for the mass of the people, any very eifectual force, and the customary law continued to exist in almost undiminished vigour until the establishment of the People's Government in 1949.2 Since then the situation has changed completely. New laws regarding marriage and property are effectively enforced, and have everywhere replaced the old customs and, what is still more important, an extremely efficient system of mass-education in the principles of Communism will before long have expelled from people's minds those beliefs on which the old Chinese law was based. From now on, apart from Formosa, it is only in Hong Kong and among the communities of overseas Chinese throughout South-East Asia that Chinese customary family law will continue to exist, but even with such limitations it is still of sufficient importance to make its study of practical significance.

Stephanopachyslinearis (Kugelann, 1792) belongs to the family of horned powderpost beetles (Bostrichidae), represented in the fauna of Europe by 29 native species. It is a characteristic element of the northern, boreal zone of the Palaearctic and alpine areas of central and southern Europe. This species as a rare beetle important for the European Union, has been placed in Annex II of the Habitats Directive, on the IUCN Red List of Threatened Species and European Red List of Saproxylic Beetles. S.linearis was described from Poland in 1792 and, after 220 years, again encountered in this country. The zoogeographical distribution is shown and elements of its biology and ecology are discussed.

The IUCN Red List of Threatened Species is the most widely used information source on the extinction risk of species. One of the uses of the Red List is to evaluate and monitor the state of biodiversity and a possible approach for this purpose is the Red List Index (RLI). For many taxa, mainly hyperdiverse groups, it is not possible within available resources to assess all known species. In such cases, a random sample of species might be selected for assessment and the results derived from it extrapolated for the entire group - the Sampled Red List Index (SRLI). The current contribution is the third in four papers that will constitute the baseline of a future spider SRLI encompassing 200 species distributed across the world.A sample of 200 species of spiders were randomly selected from the World Spider Catalogue, an updated global database containing all recognized species names for the group. The 200 selected species where divided taxonomically at the family level, and the familes were ordered alphabetically. In this publication, we present the conservation profiles of 58 species belonging to the famillies alphabetically arranged between Oecobiidae and Salticidae, which encompassed Oecobiidae, Oonopidae, Orsolobidae, Oxyopidae, Palpimanidae, Philodromidae, Pholcidae, Pisauridae, Prodidomidae and Salticidae.

Phytochemical study on the plant Premna integrifolia L. led to the isolation of twelve compounds. In which, a new acylated iridoid glycoside, 6- O-(3″- O-acetyl-2″- O-trans-p-coumaroyl)-α-L-rhamnopyranosylcatalpol (premnacorymboside A) (1), was isolated from the flowers along with 10- O-trans-p-methoxycinnamoylcatalpol (3) and verbascoside. From the leaves, a new iridoid glycoside, 6- O-(3″- O-trans-p-coumaroyl)-α-L-rhamnopyranosylcatalpol (premnacorymboside B) (2), together with 10- O-trans-p-methoxycinnamoylcatalpol (3), scutellarioside II (4), premnaodoroside A (5), 1- O-trans-p-coumaroyl-α-L-rhamnopyranoside, hexyl glucoside, 4-hydroxy-2-methoxybenzaldehyde, and 4-hydroxybenzaldehyde were obtained. The new compound premnacorymboside A (1) and scutellarioside II (4), were also isolated from the stem bark along with quercetin 3-rutinoside and leonuriside A. The structure determinations were based on physical and spectroscopic evidence.
