Klapperich beetle (Gonioctena klapperichi) and Oberthür beetle (Gonioctena oberthueri) from China

NEWS - Gonioctena Chevrolat, 1836, is currently known from the Palaearctic, Nearctic and Oriental regions. In China it now has 53 species of which about 60% are endemic with the addition of the Klapperich beetle (Gonioctena klapperichi) and Oberthür beetle (Gonioctena oberthueri).

G. klapperichi is similar to G. scutellaris Baly, 1862, and G. melanota Kippenberg, 2010, but can be distinguished by the long oval aedeagus (vs. the apical 1/3 of the aedeagus is very slender in G. scutellaris and the apical 1/3 is tapering to blunt in G. melanota). G. oberthueri can be easily distinguished from the other species by its unique coloration, slightly elongated antennae VII-XI and the shape of the male genitalia.

Hee-Wook Cho of the Nakdonggang National Institute of Biological Resources in Sangju, named Klapperichi after the German entomologist Johann Friedrich Klapperich, who collected specimens in Fujian. Oberthueri is named after the French entomologist René Oberthür who obtained the type specimen from a missionary in Kangding, Sichuan.

Gonioctena is one of the most diverse genera of the subfamily Chrysomelinae, with 9 subgenera. The main features of the other genera are the middle and hind tibiae each with an angled subapical projection, appendicular tarsal claws, elytral epipleura visible in lateral view, well-developed hind wings and a procoxal cavity opening posteriorly.

Humpback whales (Megaptera novaeangliae) manufacture bubble-nets as tools to increase prey intake

NEWS - Humpback whales ( Megaptera novaeangliae ) create bubble net tools while foraging, consisting of internal tangential rings, and actively control the number of rings, their size, depth and horizontal spacing between the surrounding bubbles. These structural elements of the net increase prey intake sevenfold. Researchers have known that humpback whales create “bubble nets” for hunting, but the new report shows that the animals also manipulate them in a variety of ways to maximize catches. The behavior places humpbacks among the rare animals that make and use their own tools. “Many animals use tools to help them find food, but very few actually make or modify these tools themselves,” said Lars Bejder, director of the Marine Mammal Research Program (MMRP), University of Hawaii at Manoa. “Humpback whales in southeast Alaska create elaborate bubble nets to catch krill. They skillfully blow bubbles in patterns that form a web with internal rings. They actively control details such ...

The surface is wavy, pale green on the underside, dark green on the top. The three main veins are central and linear. Rounded base, tapered ends and serrated edges. The inflorescences are paired, the male is a dense cyme paniculata.

Cempaki (Termitomyces microcarpus)

Cempaki ( Termitomyces microcarpus ) is a species of fungus in the Lyophyllaceae family. It grows wild in tropical Asian forests near termite nests. It is rarely reported in urban areas. It is edible and known for its deliciousness, high nutritional value, and difficulty in cultivating. In Indonesia, it is used as an alternative food ingredient. T. microcarpus is the smallest of the Termitomyces species, umbrella-shaped, plain white, measuring 5 cm tall and 2.5 cm wide. It grows in dense clusters on surfaces and forms a mutualistic relationship, requiring the metabolic activity of termites as a substrate for growth. This species is known for its deliciousness, rich in nutrients, and has potential bioactive properties, such as helping lower cholesterol and acting as a tonic. Currently, it is difficult to cultivate on a large scale, and people rely solely on wild harvests. This mushroom is highly favored for its savory, delicious flavor and soft, chewy texture. It is often stir-fried ...
