Abstract:
A new subspecies of Sideroxylon mascatense (A.DC.) T.D.Penn. in the Western Hajar Mountains, differing from the type subspecies in the colour of the mature fruit, is described. The two colour forms are genetically isolated, showing that these two are distinct taxa.Keywords:

There are 14 subspecies in the world (Mayr & Paaynter,1964;Howard & Moore,1980),5 subspecies recorded in China (Cheng,1987,1994;MacKinnon et al.,2000),3 subspecies recorded in Yunnan Province.Seven adult specimens of Chestnut-crowned Laughingthrush collected from the Ailaoshan Mountain region in Jindong,Shuanbai,and Xinping et al.counties of Yunnan,were discovered to have essential differences from all other recorded subspecies of Chestnut-crowned Laughingthrush and distribute in certain specific areaTherefore,they are identified as a new subspecies and named as:The Ailaoshan subspecies of Chestnut-crowned Laughingthrush Garrulax erythr ocephalus ailaoshanensis subsp.nov.

The taxonomy of honey bee A. mellifera contains a lot of issues due to the specificity of population structure, features of biology and resolutions of honey bee subspecies discrimination methods. There are a lot of transition zones between ranges of subspecies which led to the gradual changes of characteristics among neighbor subspecies. The modern taxonomic pattern of honey bee Apis mellifera is given in this paper. Thirty-three distinct honey bee subspecies are distributed across all Africa (11 subspecies), Western Asia and the Middle East (9 subspecies), and Europe (13 subspecies). All honey bee subspecies are subdivided into 5 evolutionary lineages: lineage A (10 subspecies) and its sublineage Z (3 subspecies), lineage M (3 subspecies), lineage C (10 subspecies), lineage O (3 subspecies), lineage Y (1 subspecies), lineage C or O (3 subspecies).

For subspecies divergence of red panda,two subspecies of the red panda ( A.f.fulgens and A.f.styani ) have been described.However,the validity of these two subspecies is argued because of the significant variation in coloration among individuals of same subspecies.Therefore,further taxonomic study within the genus is recommended by the conservation biologists to examine the validity of the two described subspecies.In this study,DNA fingerprinting technique is applied to validate the present subspecific status of red panda.Our results obtained from DNA fingerprints indicate that all individuals of A.f.styani have a 8 4?kb band which the individuals of A.f.fulgens lack.Conversely,all individuals of A.f.fulgens share another band of 1 8?kb which individuals of A.f.styani lack.These two characteristic bands can pass on parents to offsprings,which meet Mendelian fashion.Furthermore,differences in polymorphic and genetic variations between two subspecies also indicate that the gene flow between two subspecies might become smaller and smaller after these two subspecies are formed.This further supports that there are genetic divergences of two subspecies and the status of two subspecies is valid from the view of genetic level.

Two new subspecies of Therates alboobliquatus (Horn, 1909), amisi new subspecies and fangi new subspecies are described. An identification key of all subspecies of alboobliquatus is given. The subspecies are distinguished by the shape of the midline on the elytra. The distribution of the subspecies corresponds to the regional climatic patterns of Taiwan.

A new subspecies of Leionema lamprophyllum, formerly included in L. lamprophyllum subsp. obovatum F.M.Anderson, is here described as new. Currently known from fewer than 50 individuals, the new subsp. is highly restricted and warrants a conservation risk code of at least Endangered. An illustration of the new taxon, notes on its distribution and habitat, and a key to all four subspecies of L. lamprophyllum are also provided.

Crepispalaestina subsp. babcockii Inceer & Aksu Kalmuk subsp. nov. (Asteraceae, Cichorieae) is described and illustrated. It grows in shady places and red pine forest in southwest Anatolia, Turkey. The chromosome number of the new subspecies is 2n = 2x = 8. The diagnostic morphological characters that distinguish C. palaestina subsp. babcockii from morphologically similar taxa C. palaestina subsp. palaestina and C. pulchra are discussed, and a conservation status for the new taxon is suggested.Bangladesh J. Plant Taxon. 25(1): 45-49, 2018 (June)
