Ranela (Selaginella plana)

Ranela or Asian spikemoss (Selaginella plana) is a species of plant in Selaginellaceae, fibrous roots, creeping in the forest, stems 0.5-1 cm in diameter, yellowish brown and slightly grooved, used by local residents as an antidote to demons and treat poisonous snake bites.

S. plana has green leaves with small and simple sizes that resemble flat scales, smooth surface, encircling the trunk and on the side branches arranged in four rows where the two side leaves consist of large leaves that fall off easily and two front rows of small, attached leaves.

Leaves are not stemmed, appear crossed, smooth surface. Ranela produces two types of spores that are not the same size. Sorus grows at the tip of the terminalia. Sporangia in fertile axillary leaves. The sporophyll is larger than the sporangia, collected into rectangular and sometimes slightly flattened terminal grains.

Shaded terrestrial at an altitude of more than 200 m in the tropics. Often used as an ornamental plant. In some areas it is used as a wound medicine, blood purifier, stomachache medicine and fever medicine by bathing using boiled water.

Laniger bat tick (Ixodes lanigeri), new hard tick species (Ixodidae) from mouse-eared bats (Myotis) in Vietnam

NEWS - Researchers have identified Ixodes ticks from Vietnam based on morphological and molecular characteristics of females, nymphs and larvae as a new species, laniger bat tick ( Ixodes lanigeri ), which like other members of the Ixodes ariadnae complex appears to show a preference for vesper bats as a typical host. Historically, for more than a century and a half, only one species has been called the “long-legged bat tick”: Ixodes vespertilionis Koch. However, over the past decade, it has been molecularly recognized that long-legged ixodid ticks associated with bats may represent at least six species. Host associations and geographic separation may explain the evolutionary divergence of the new species from its closest living relative Murina hilgendorfi Peters in East Asia, Japan, as no Myotis or Murina spp. have overlapping distributions between Vietnam and the Japanese mainland. On the other hand, assuming that I. lanigeri may be present in other myotine bats and knowing that s...

Giant golden spider (Nephila pilipes)

Kemlanding or giant golden orbweaver ( Nephila pilipes ) is an animal species in the Araneidae, a web spider with a vertical and asymmetrical mesh, sexually dimorphic with elongated females up to 20 cm in size and has a large investment in egg production and web construction, whereas males only a few millimeters. N. pilipes displays female gigantism and male dwarfism. Females usually have a body size of 30-50 mm, the cephalothorax is 15 mm long and 10 mm wide. The stomach is 30 mm long, 15 mm wide and is mostly tawny with yellow stripes. The female has black or brown, covered in thick hairs. The two rows of eyes stick out towards the back. Plastron is mostly black and brown. The legs are very long, stick-shaped with several joints, black and yellow, lacking of hairs. Males are 5-6.5 mm in size, cephalothorax is 2.5 mm long and 2 mm wide. The stomach is 4 mm long and 1.5 mm wide. The front eye is bigger than the back eye. The legs are light brown with some hair.
