Sensitive plant (Mimosa pudica)

Putri Malu or shy princess or action plant or sensitive plant (Mimosa pudica) is a short shrub in Fabaceae and is easily recognized by leaves that quickly close when touched. Although a number of legion members can do the same, shy daughters react faster than other species.

M. pudica folds leaves only temporarily where a few minutes will recover or expand as before. This plant will also close the leaves when blown by the wind or exposed to heat. The process occurs by changes in turgor pressure in the leaf bone. The stimulation was also felt by other leaves that were not touched.

Dlium Sensitive plant (Mimosa pudica)

This seismonastic motion is an example of a tigmonastic movement that does not care where the touch comes from. The sensitive plant also folds the leaves at sunset and will recur after sunrise.

Basically shy princess plants close the leaves to protect themselves from herbivores who want to eat them. The color of the lower leaves is paler in color to make the animal think that the plant has withered and is no longer interested in eating.



The action plant has erect stems when young, but it creeps with age. The stems are slender, branched, slightly spiny and grow to a length of 1.5 m. The leaves are bipinnately compounds with one or two pairs of pinnae and 10-26 leaflets per pinna. The leaf stalks are also spiny.

The head of the pedunculate flower is pale pink or purple emerging from leaf axils with more flowers as the plant grows older. Fruit consists of groups of 2-8 pods for 1-2 cm long. The pods break into 2-5 segments and contain pale brown seeds of around 2.5 mm.

Kakizoe darkling beetle (Microblattellus kakizoei) is the second species after Microblattellus lecongmani Ferrer 2006

NEWS - Kakizoe darkling beetle ( Microblattellus kakizoei sp. nov) collected from a mushroom-growing termite nest of Macrotermes gilvus (Hagen, 1858) in Cambodia was established as the second species in the enigmatic tenebrionid genus Microblattellus Ferrer 2006. Microblattellus was established by Ferrer in 2006 as consisting of a single morphologically peculiar species represented by Microblattellus lecongmani Ferrer 2006 from Vietnam. The genus is characterized by a very distinctive pronotum shape, in which the head is completely hidden beneath the anterior margin, and the absence of eyes. M. kakizoei is easily distinguished from M. lecongmani by its more elongate and less robust body, looser antennal segments, distinct and transverse scutellum, rather than the reduced and absent one in the latter, distinctly formed humeral angles of the elytra, finely arranged and irregular strial punctures on the elytra, and less prominent body surface. The holotype is taken from the fungus Ma...

Ralph Holzenthal caddisfly (Rhyacophila lignumvallis) from Corsica in Rhyacophila tristis (Schmid 1970) group

NEWS - Ralph Holzenthal caddisfly ( Rhyacophila lignumvallis Graf & Rázuri-Gonzales, sp. nov.) from the island of Corsica (France) was established as a new species in the Rhyacophila tristis (Schmid 1970) group based on morphological analysis and the mitochondrial cytochrome c oxidase subunit I (mtCOI), including sequences from 16 of the 28 species in the group. Rhyacophila Pictet 1834 with 814 living and 30 fossil species is the largest genus of caddisflies in the world, distributed mainly in the northern hemisphere, but also in temperate and tropical India and Southeast Asia. One of the groups is the R. tristis group in the branch Rhyacophila invaria . R. lignumvallis is most similar to Rhyacophila pubescens Pictet 1834, Rhyacophila tsurakiana Malicky 1984, Rhyacophila ligurica Oláh & Vinçon 2021, Rhyacophila harmasa Oláh & Vinçon 2021 and Rhyacophila abruzzica Oláh & Vinçon 2021. However, R. lignumvallis differs in the shape of the X tergum, the dorsal arm ...

Three new species of Huntsman spider (Pseudopoda Jäger 2000) from Qizimeishan National Nature Reserve

NEWS - A spider survey in Qizimeishan National Nature Reserve in Xuan’en County, southwest Hubei Province, adjacent to the northeastern edge of the Yunnan-Guizhou Plateau, discovered three new species: arc huntsman spider ( Pseudopoda arcuata ♀), Qizimeishan huntsman spider ( Pseudopoda qizimeishanensis ♂ ♀) and Mian Wei huntsman spider ( Pseudopoda weimiani ♂ ♀). The reserve covers a total area of 345.5 km2 and the highest peak is about 2010 meters. It mainly protects the central subtropical mountain evergreen broadleaf forest and subalpine sphagnum swamp wetland area. The reserve is rich in wildlife resources and has been listed as a key biodiversity area in the China Biodiversity Conservation Action Plan. Pseudopoda Jäger 2000 is the largest genus of the Sparassidae Bertkau 1872 with 256 species. Currently, 155 species of Pseudopoda are known in China. This genus is a small to large spider that lives mainly in leaf litter and less frequently in plants. P. arcuata derives its spe...
