A new deltocephaline leafhopper genus Hamulotettix is described and illustrated based on a large, distinctly patterned species, Hamulotettix ungulatus sp. nov., from China and Thailand, and is tentatively placed in the tribe Athysanini. Detailed morphological description and illustrations are provided. The genus is similar to Abrus Dai & Zhang in external body form, and also bears a superficial...

Five new species of Hypseloecus viz., Hypseloecus acutus sp. nov., Hypseloecus articulatus sp. nov., Hypseloecus belli sp. nov., Hypseloecus orientale sp. nov. and Hypseloecus spinosus sp. nov. are described from India. The genus is recorded for the first time from India collected on hemiparasitic plants of the genera Dendrophthoe and Viscum (Santalales). A key to identification of the five spe...

Hedychium putaoense Y.H. Tan & H.B. Ding, a new species of Zingiberaceae from Putao, Kachin state, Northern Myanmar, is described and illustrated. It is similar to H. densiflorum Wall. and H. longipedunculatum A.R.K. Sastry & D.M. Verma, but differs by its very small bract (4-6 × 2.5-3 mm vs. 18-19 × 5-5.5 mm and ca. 11 × 7 mm, respectively), semicircle and dark red bracteole, orange flower and...

An unusually coloured, small baleen whale was documented off the southern coast of Sri Lanka in February 2017 during routine field surveys. Based on five distinct morphological characteristics including jaw asymmetry, presence of a prominent central rostral ridge, blaze on right side, asymmetrical chevron on left and right sides and a strongly falcate dorsal fin the individual was positively id...

Immunomodulators are agents that are able to stimulate or inhibit the immune response. The leaf extracts from Potentilla indica and Dendrophthoe pentandra were analyzed in vitro for immunomodulatory activity and an MTT colorimetric assay was conducted to determine the proliferation of mice splenocytes and thymocytes. A bromodeoxyuridine assay was performed to analyze DNA synthesis and the Trypa...

The leaves of Dendrophthoe falcata growing on different trees had differing dry solid content. With 1 exception, the parasite leaf contained less dry solid than host leaf.A characteristic feature of the loranthus parasite was the accumulation of phosphate in excess of that present in host leaves. Expressed as percent of the total phosphorus, the parasite tissue contained significantly less acid...
