As part of a review in progress on the genus Clusia Linnaeus in Venezuela, Clusia ucamira J.E. Nascim. & Bittrich is reported for the first time for that country. Clusia ucamira is quickly distinguished from similar species of Clusia sect. Oedematopus (Planchon & Triana) Pipoly by its hemiepiphitic habit, strongly coriaceous and conspicuously revolute leaves, with a very prominent midvein in the abaxial surface. With this range extension, Clusia ucamira is known, besides from the Amazon basin, from terra firme forest in the Amazonas state of Venezuela, where it grows in oligotrophic soils derived from materials from the Guayana Shield. In Venezuela, this species is to be considered Least Concerned (LC), according to the IUCN Red List categories.

Miconia angustidentata, from upland rain forest in northwestern Guyana, is described, illustrated, mapped, and compared with its superficially similar species based on morphological features. It is characterized by its ovate to elliptic 3–5-nerved entire leaves; axillary clusters of 3–5 sessile mostly 5-merous flowers; sparse cover of minute stellate trichomes on abaxial foliar surfaces, hypanthia, and calyx lobes; conspicuous oblong calyx teeth that obscure calyx lobes at anthesis and in fruit; white oblong petals that lack a subapical mucro on the abaxial surface; white stamens with ventrally inclined anther pores; (4–) 5-locular superior ovary; and ovoid-pyramidal angulate seeds with an irregularly rugulate testa and a raphe that extends about 50% the length of the seed. A conservation assessment of Endangered is recommended for this species based on IUCN Red List Categories and Criteria.

Euastrum lacustre is reported for Russia for the first time. This alcaliphilic species was found in the periphyton and plankton of three lakes in the Kursk Region (European Russia). A description of morphology, including the relief of cell wall, and habitats where this taxon is found are represented. LM and SEM microphotographs are provided. Morphological differences of E. lacustre from similar species are discussed. New species for region, namely Closterium aciculare, Cosmarium formosulum, C. granatum, C. pseudoinsigne, C. reniforme and Staurastrum pingue, are found in the samples together with E. lacustre.

Immature stages of many Brazilian Smicridea species remains unknown, and efforts to describe all life stages are required. In this paper, the larva and pupa of Smicridea (Rhyacophylax) gladiator Flint 1978, associated with adults through the metamorphotype method, are described and illustrated. In addition, the known distribution of this species is extended in the Brazilian Amazon Basin with new records from Amazonas state and the first record in Pará state. Information about its bionomics is also provided.

The notoriously destructive and invasive soft scale, Pulvinaria urbicola Cockerell (Hemiptera: Coccidae), is recorded for the first time from India. This scale, with variable morphological appearance and similarities with other known scales of the same genus established in India, is redescribed to facilitate its identification and separation from other similar species. Information on its host range, natural enemies and distribution is provided. Management options in the event of an outbreak are discussed briefly. A key to the species of Pulvinaria Targioni Tozzetti in India is also provided. This new arrival warrants special attention in India as it is a potentially damaging plant pest and has a broad host range across many plant families.

Begonia yizhouensis, a new species in Begonia sect. Coelocentrum (Begoniaceae) from Guangxi of China, is described and illustrated. Morphologically, it is similar to the adjacently distributed B. luochengensis, but clearly separated by its waxy leaves with glabrous or sometimes sparsely puberulous surfaces, larger variation in leaf color and maculation along the main veins, white to pinkish-white flowers and late flowering. Furthermore, molecular phylogenetic analysis indicated B. yizhouensis was a monophyletic lineage and was sister with B. luochengensis. The relationship of the new species and other similar species is also discussed. This new species is endemic to limestone hills in Guangxi and is assessed as “Endangered” (EN) according to the IUCN Red List Categories and Criteria. Additionally, morphological and molecular evidence for B. yishanensis not being synonymous with B. porteri is presented.

A New Species

Begonia leipingensis D. K. Tian, L. H. Yang & C. Li (2n = 30), a new species in Begonia sect. Coelocentrum from the limestone area of Guangxi, China. B. leipingensisis is easily distinguished from any other compound-leaved species in Begonia by its large variation in petiolule number and its unique spirally-arranged petiolule pattern, which has never been seen in Begoniaceae before and rarely seen even in other angiosperm taxa. Besides having non-overlapping flowering periods, it is clearly different from B. fangii, the most morphologically similar species in the same section and with the same chromosome number. In addition to its unique petiolule pattern, B. leipingensis has longer abaxial wings, shorter internodes, and usually larger leaves, leaflets and habit. Molecular phylogenetic analysis showed that B. leipingensis formed an independent lineage belonging to Sect. Coelocentrum. Morphological and phylogenetic evidence strongly supports this species as a new taxon in Sect. Coelocentrum of Begonia. B. leipingensis was assessed to be critically endangered based on criterion outlined by IUCN Red List Categories and Criteria.

Spiradicliskarstana, a new species of Spiradiclis (Rubiaceae) collected from Yunnan, China, is described for the first time. It is morphologically close to S.jingxiensis, but differs from the latter mainly by its inflorescences with 5–9 flowers, its 1.5–2.4 mm long peduncles, its stipules shorter than 1 mm and the 5–12 pairs of secondary veins. The conservation status is assessed as “Vulnerable” (VU) according to the IUCN Red List Categories and Criteria.

Dracaena cambodiana Pierre ex Gagnep., a dragon tree species, is reported here for the first time from India. Its taxonomic relationships with other closely related species of genus Dracaena Vand. ex L. are examined and discussed. A detailed taxonomic description, along with color photographs is provided to facilitate its future identification. Recent surveys confirm that the habitat and regional population of the plant is under severe threat. Hence, following IUCN Red List Categories and Criteria, it is regionally categorized as Critically Endangered.
