Unraveling a 146 Years Old Taxonomic Puzzle: Validation of Malabar Snakehead, Species-Status and Its Relevance for Channid Systematics and Evolution

The current distribution of C. diplogramma and C. micropeltes is best explained by vicariance. The significant variation in the key taxonomic characters and the results of the molecular marker analysis points towards an allopatric speciation event or vicariant divergence from a common ancestor, which molecular data suggests to have occurred as early as 21.76 million years ago. The resurrection of C. diplogramma from the synonymy of C. micropeltes has hence been confirmed 146 years after its initial description and 134 years after it was synonymised, establishing it is an endemic species of peninsular India and prioritizing its conservation value

PRELIMINARY REVISIONS OF SOME GENERA OF MALAYSIAN PAPILIONACEAE II

The revisions or notes have been prepared by Miss M. S. van Meeuwen, except for those of Pseudarthria and Sophora by C. G. G. J.van Steenis, and Tephrosia by J. Stemmerik. In Alysicarpus 4 species are distinguished in Malaysia; a key, synonymy, and discussion are given.Lourea Desv., being a homonym, has, according to Dr. Bakhuizen van den Brink, to be replaced by Christia; a key and discussion is given of 4 Malaysian species; 5 new combinations are proposed. Under Desmodium the variability of D. heterocarpon (L.) DC. and its full synonymy are discussed; one new variety is proposed; an enumeration of specimens of both varieties is given. D. ormooarpoides DC. and D. zonatum Miq. are two sharply distinct species which have been confused in the past; a key, synonyms, discussion, and enumeration of specimens are provided. The discrimination of D. sequax Wall, and D. viegaphyllum Zoll. is discussed and their synonymy given; specimens have been enumerated. Distribution is given of D. scorpiurus (Sw.) Desv. and D. tor-tuosum (Sw.)DC. Psoraleai is revised for Malaysia where 4 species are recorded and keyed out; a fifth species must remain dubious, as the type could not be traced in the Paris Herbarium. Of Pseudarthria only one species occurs in Malaysia; its synonymy and distribution is given.Sophora longipes Merr.; an endemic species from the Philippines, is recorded for Timor. Of Tephro&ia maculata M. & P., from Papua, the synonymy is given and specimens enumerated; T. brachystachys Laut. & K. Seh. is reduced. Notes and distribution are given of T. zollingeri Backer. For T. mollie . Val., a later homonym, the new name T. papuana is proposed
