A New Species

A new species of Quercus (Fagaceae), Q. ngochoaensis, from Ba Vi National Park, Ha Noi, northern Vietnam is described and illustrated. This species is morphologically similar to Q. glauca in having glabrous twigs, cuneate leaf base, two or three fruits per infructescence, almost entire margin of lamellate rings on cupule except the lowest three rings, slightly convex scar at the base of a nut. However, it differs from Q. glauca in having smaller leaves, cup-shaped cupule enclosing 1/2–2/3 of the nut, 7–8 lamellate rings on cupule, and subglobose nut. In addition to the description, DNA barcodes of the two partial plastid regions of matK, rbcL and the nuclear region of ITS of the new species are provided.

A new species of the genus Eurostocepheus (Oribatida, Otocepheidae) is described from soil and litter of Tam Dao National Park in Northern Vietnam. Eurostocepheus (Eurostocepheus) wojciechniedbalai sp. nov. is morphologically most similar to E. (E.) mahunkai Mondal & Kundu, 1999 from India in the presence of four pairs of genital setae and medial prodorsal condyles, but differs by the quadrangular, anteromedially excavated lateral notogastral condyles, short interlamellar setae, short notogastral setae c, minute epimeral setae 1a, 2a, 3a, two pairs of epimeral setae on epimere IV, and by the transverse position of the anal setae. Revised generic and subgeneric diagnoses, an identification key to the known taxa, and data on the distribution and ecology of Eurostocepheus are presented.
